Slopes on windows: which ones are best to make. Are plastic slopes better or plasterboard? What is better: plastic slopes or plaster ones?

How to make slopes on windows? This question worries many who, after replacing window structures, are faced with such a problem. Indeed, it remains to be done serious work, which will make the surfaces reliable and beautiful. It is worth considering that slopes are not only decorative, but also protective function. Therefore, it is necessary to approach this with utmost care. If you make mistakes or do the work poorly, a lot of troubles will arise.

Window slopes are an integral part of any room. Some believe that minimal attention can be paid to such a design. But this is a misconception that leads to aesthetic and practical problems. The fact is that internal slopes perform a number of important functions:

1. Maintain a certain microclimate. Slopes prevent heat from escaping from the room to the outside, as well as preventing cold from penetrating inside. Naturally, protection from moisture, which leads to the formation of condensation, cannot be ruled out.
2. Extend the service life of all structures. That is why such finishing must be carried out in a short time. Of course, you can still delay installation indoors, but outside, installing the slopes is required within a minimum time.
3. They create an excellent decorative component. Installing slopes on windows can be considered one of the main components of a harmonious interior. You can install beautiful metal-plastic frames, but if they are not properly refined, they will lose their sophistication.

Therefore, when performing all the work yourself, you must comply with all technological nuances and rules. Then you can be sure that you will get a reliable and durable coating that will please the eye.

Design Features

The design of slopes has its own characteristics. The fact is that it is necessary to take into account the main nuances that must be done when working with your own hands:

• The structure should be finished so that the edge of the frame is covered quite a bit.
• It is necessary to take into account the location of hinges and opening doors.
• The foam is trimmed flush with the frame. If you delete more substances than required, then a distortion of the structure may occur. Also, any bulging residue will interfere with the finishing process.
• Particular attention is paid to the installation seam. The option that will be used for cladding the window slopes depends on its thickness.
• The sealing process is very important point. All places must be well coated.

But how to finish the slopes, the location outside the room? The technology is almost completely consistent internal work. But the obligatory and most important rule will be to install a low tide.

Finish options

It is customary to distinguish two main cladding options, which differ in the materials used.

Cladding with panel products

This technology assumes that materials will be used that are cut into panels of the required size.

When choosing this method, the following features should be taken into account:

1. Quality of material. It is necessary to carefully select the products used. The fact is that if you install a low-quality option, then problems will begin to arise during the installation process. For example, cheap plastic is characterized by the fact that it crumbles and cracks when cut, and after installation it does not retain its good appearance for long.
2. Correct insulation and processing technology. When installing panel products, voids often appear, which can serve as an opportunity for the development of fungus and mold. Such places are a source of cold penetration. Therefore, surfaces need pre-treatment and installation of insulation, the choice of which depends on the specific situation.
3. Careful measurement. The main mistake that can happen is inaccuracies in measurements. If you do not take into account the location of the parts, wide joints will form that cannot be hidden even with decorative moldings.
4. Finishing. Installation of slopes from panel products must be combined with the correct selection decorative elements. For subsequent finishing, you can use special profiles and corners, as well as putty external joints. When installing overhead fragments, it is important to make the correct trim so that all joints are equal.

Note! To produce the most accurate parts for window slopes, two methods are used. The first is to simply measure and transfer data to the material, the second is to create stencils. This method is much more accurate, but requires more time, because it is necessary to perform a stencil at each stage of the work.

Application of the solution

Such work involves applying a certain layer of prepared mortar to the windows yourself, which completely covers the entire surface of the slopes. This option is considered the most traditional. His distinctive feature is cheapness.

Finishing can be carried out according to two main scenarios:

1. Traditional. The surface is finished with a mixture that is leveled at a certain angle.
2. With additional insulation. This technology involves the use of foam plastic, which serves as the base. In reality, this option can be fraught with many problems. Improper installation of insulation is a guarantee that numerous cracks and peelings will appear.

Preparatory activities

Before wondering how to properly make slopes, you should thoroughly prepare the surface. The amount of work depends on the specific situation. Exists general order, which is required:

Slope manufacturing technology

How to finish the slopes? There are basic materials that are used for such work:

• plastic PVC panels for walls;
• sandwich panels;
• plaster.

Each option is selected based on several reasons:

• Distance from wall to window frame. That is, the thickness of the assembly seam.
• Width of plots.
• Financial costs.

Considering that the master must perform all the work himself, the option that will be most acceptable is chosen.

PVC panels for walls

PVC panels are the most popular material for finishing window slopes

This material is used most often, especially if needed. There are several reasons for this:

1. Cheapness. Modern technologies make it possible to produce products that are accessible to everyone.
2. Practicality. If you choose materials that do not belong to the category of economy, then they are unpretentious in operation and last quite a long time.
3. Easy to install. The work is completed quickly, without the use of complex tools.

Installation of slopes made of plastic panels is carried out according to the following instructions:

But the window decoration is not finished yet. A number of finishing manipulations should be performed. They consist in the fact that all joints are well coated with sealant. Decorative corners are installed on the outside. They must be trimmed correctly in order to join at an angle of 90 degrees.

When a dilemma arises about which slopes are better, many proposals and opinions may arise. But it is undeniable that it is better to make slopes from sandwich panels. They combine all the positive qualities of PVC materials, but have additional advantages:

• The products include a reliable layer of protection (one or two), as well as a layer of insulation. This avoids the need to use additional material.
• They are resistant to various influences, due to which their service life is practically unlimited.
• Have excellent decorative look. Indeed, such panels are superior in appearance to wall products. Besides this material can be made in a fairly wide size, which is ideal for large openings.

Making slopes on windows with your own hands using such products is quite simple. It must be taken into account that this option is excellent in cases where the thickness of the installation seam is minimal. Three-layer material is used for work.

Let's look at how to install slopes from sandwich panels. Everything is done as follows:

Using plaster

Previously, there were no questions about how to make slopes on windows. After all, there was only one option, which was to use plaster. This method quite convenient and practical, but requires skills. This need arises due to the fact that it is necessary to correctly display all the planes and maintain the angle of inclination. Although, if you practice a little and understand how best to apply the mixture, then plastering work will not cause any particular difficulties.

The general technology is as follows:

The result is an excellent coating that is highly reliable. The undoubted advantage of this option is that each section made can be repaired and the decorative layer can be changed.

Conclusion

Summarizing the above, we can conclude that there are various options finishing of window slopes, which depend on the specific situation and financial capabilities. The main thing is to initially carry out all the work efficiently, observing all the nuances.

Choosing the right slopes for plastic windows.

Installation of slopes is an important stage in window installation. Slope - inner part window opening, the place where the window itself is inserted. When you have to replace a window, you need to pay attention to the slopes; the higher their quality, the better the overall appearance will be.

When installing PVC windows, today we offer following types slopes:

• plasterboard;
• plastering;
• plastic.

Without a window frame, any newest and highest quality window will look unfinished and sloppy. And they often find out about slopes during the process of renovating an apartment or when replacing windows. There is an explanation for the fact that the old slopes stood for quite a long time without a single crack. The old window design had increased air permeability. There was air blowing from the loose fit and cracks, which created a gentle temperature zone for the slopes. But the modern design of wooden and plastic windows is airtight. Air does not enter the cracks, which simply do not exist, and the slopes are located between the cold outside and the heat inside, that is, on temperature limit, which is expressed quite sharply. When you open a window to ventilate, cold air hits the heated slope, causing it to crack. Condensation also plays an important role.

Plaster slopes for plastic windows

The plaster mixture from which the slopes are made is not firmly connected to the PVC frame, and this will sooner or later lead to detachment of the slope. There are no materials in the plaster slope that have good heat-insulating properties; this leads to overcooling of the opening and the window itself in cold weather. This causes condensation, both on the slope and on the glass unit.

Making plaster slopes takes a lot of time. According to the technology, the material is applied in layers, and each new layer can be laid only after the previous one has dried. Otherwise the surface will crack. Plaster, which is applied to concrete or brick, continues the wall. Therefore, the slopes turn out to be cold and freeze at the junction with the frame. By the way, look at what we have now, the most common technology is oknadena.

Plasterboard slopes

The same disadvantages also apply to slopes made of wood, which still require good fastening. If you glue thin plastic onto a sheet of drywall, the quality will also not be up to par: this is labor-intensive work with insufficient stability of the drywall and unreliable adhesive connection, which also leads to destruction.

Thin plastic sheets are not suitable for finishing, although this is one of the most simple ways finishing. In this case, the window frames are not insulated, which leads to freezing and condensation, and the method of gluing the plastic leads to peeling due to compression/expansion of the material.

PVC plastic slopes

Now on the market building materials you can find panels made of cellular plastic. When insulating with mineral wool, using a mounting profile, or fastening panels to a batten, you can use this material. Here you should choose the most quality manufacturers. Cheaper panels change color over time, stiffening ribs are visible on the front surface, which in turn leads to a loss of the overall attractiveness of the window, creating the impression of handicraft finishing of a window opening with a high-quality window.

Slopes made of MDF panels They are quite cheaper in cost than those made from plasterboard, do not have sufficient moisture resistance and require high-quality fastening.

For single-sided sandwich panels good aesthetic characteristics, but lacks sufficient rigidity. This is especially undesirable when wide slopes, since the slope will sag.

Today, two-layer sandwich panels and special plastic slopes, which are considered the highest quality and most practical to use, although they are more expensive than others.

Installation of plastic slopes

In terms of installation, installation of slopes for PVC windows is the simplest. In addition, plastic, unlike other materials, can tolerate deformation to a critical point. If wooden slope cannot withstand seasonal temperature changes and deforms without varnish protection, then plastic calmly tolerates both moisture and temperature changes. From a decorative point of view, slopes can resemble the texture of finishing options such as metal and wood. This is achieved by lamination with a special film that imitates these materials. Find out about it, which will be very interesting.

The installation of practical and beautiful plastic windows is accompanied by the need to finish the slopes, which provide the window opening with better thermal insulation and give a complete appearance. The choice of building materials and technology for finishing slopes depends on a number of factors: the tightness of the material, resistance to moisture and temperature changes, appearance (compatibility with the interior of the room), cost.

The most practical and popular materials for finishing the slopes of plastic windows today are plasterboard and plastic sandwich panels. Let's look at the positive and negative aspects of using each of them.

Drywall slope

Drywall, consisting of two sheets of cardboard with gypsum filler inside, is an environmentally friendly material. To install window slopes, moisture-resistant plasterboard is used.

Mounted in two ways: framed and frameless. The frameless method is used on flat slopes and involves installing the material using mounting adhesive. The frame method is used when uneven surface slopes.

Drywall is attached to wooden beam or on a design from metal profiles(pre-installed with dowels). To improve thermal insulation, it is advisable to insulate plasterboard slopes with polyurethane foam or mineral wool. After installing the slopes, the seams and surface irregularities are sanded and treated with sealant, and the outer end part along the perimeter is closed with a corner. The last stage is painting or wallpapering.

Advantages of plasterboard slopes:

1. The material is durable and, with proper care, can last up to 20-25 years.

2. A slope made of plasterboard has good thermal insulation qualities (especially in combination with foam or mineral wool).

3. Unlike other materials, all kinds of defects (scratches, dents from impact and any surface contamination) can be easily eliminated on plasterboard.

4. Relatively low price.

Disadvantages of plasterboard slopes:

1. Low moisture resistance of the material. Using drywall in areas with high humidity will result in the need to periodically repair and paint the surface.

2. Difficulty in installation. Installing plasterboard slopes takes a lot of time. In addition, cutting and adjusting the material will lead to the formation large quantity dust and debris in the apartment.

Slope made of plastic sandwich panels

The sandwich panel, due to its structure (plastic, polystyrene foam insulation and moisture-resistant PVC), is an excellent thermal insulation material. It has a quality certificate and is safe for human health.

Most often, the installation of panels is carried out simultaneously with the installation of the window. To do this, it is enough to precisely cut the material and insert it inside a pre-established starting profile. The sandwich panels are attached to the slopes using mounting adhesive. At the top, the end part along the perimeter is closed with an F-shaped profile. Thus, the installation procedure is completed.

Advantages of slopes made of sandwich panels:

1. The technical characteristics of the panel provide the slopes with durability and excellent thermal insulation; there is no need for additional insulation.

2. Unlike other materials, sandwich panels do not require processing or painting after installation. The color matches the color of the window frame.

3. The panels are resistant to temperature changes and high humidity, making them easy to care for (for example, wash with detergents).

4. Fast and clean (compared to plasterboard) installation.

Disadvantages of slopes made of sandwich panels:

1. The main disadvantage of the material is that if the surface of the panel is damaged, the defect (pothole, deep scratch) cannot be quietly eliminated. As a result, the entire panel will have to be replaced.

In addition, these panels are quite soft and are easily pressed, for example, by blinds fittings when opening a window.

2. The price of some models of sandwich panels can significantly exceed the cost of other materials (for example, drywall).

Which slope finish should I choose?

We usually make our choice taking into account proposals from professionals who will supply and install windows, including price proposals. For example, you can find out about plastic windows from a manufacturer in St. Petersburg from representatives of the StroyKomfort company. But in principle, you can decide on the option for finishing the slopes even before calling the experts, taking into account the above-mentioned properties of the materials. First of all, for this you need to know:

Type of premises (residential, commercial, special purpose). So, in a room subject to large temperature changes and high humidity, drywall should not be installed.

Dimensions and characteristics of the window opening. Usually in heavily damaged window opening make plasterboard finishing of slopes.

Contamination of the premises, i.e. the possibility of wet cleaning of slopes.

In any case, no matter what material you choose, the main thing is to produce high-quality installation of the slopes themselves. Not only the appearance of the room, but also the tightness of the window opening and the thermal insulation of the entire room will depend on this.

The final stage of the installation process of modern double-glazed windows is the finishing of the slopes. They are needed not only for decorating a window opening. Thick double-glazed windows and reliable fittings provide excellent thermal insulation, but the interface between the window frame and the apartment wall remains the weak point of the structure. This problem area needs to be covered. Let's find out which slopes are best suited for plastic windows.

Before considering window framing options, their advantages and disadvantages, let’s determine what is required of these elements.

• Not inferior to the durability of the window design. Modern double-glazed windows are designed for a minimum of 15–20 years of operation. Slopes must withstand no less time without loss of basic qualities. Few people would like to redo them every two or three years.
• Comply with the general style of the window, forming a single whole with it.
• Maintain or even improve the performance characteristics of plastic windows.

When renovating an apartment in a new building or replacing windows, you will have to choose how to finish the openings after installing modern structures with double-glazed windows.

Window slopes can be finished using the following materials:

The manufacturing technology consists of sequential application of several layers of plaster and putty mortar. The finishing putty layer is painted.

Finishing a window opening with plaster has the following advantages:

• Versatility. This material is used in rooms with different humidity and temperature levels.
• Reasonable price. Plaster is an inexpensive material, and you can also save money by doing the work yourself.
• Strength. Plaster slopes are more resistant to mechanical stress compared to other types of finishing.
• No seams. Perhaps the main argument of supporters of such a coating is that there is no need to additionally process the joints and interfaces of the opening planes.
• Possibility of updating and repair.

But a number of serious shortcomings have led to the fact that plaster is used less and less for work of this kind:

• Duration and complexity of the process. Finishing takes considerable time: each layer of the plaster mixture needs to dry.
• A large amount of dust and dirt, risk of scratching the window.
• Low thermal insulation properties of plaster. Such slopes are prone to freezing in winter and condensation. In addition, when installing them, you have to cut the foam one or two centimeters inward, weakening the thermal insulation seam.
• Detachment from frame. It is impossible to firmly connect the plaster and the PVC frame. There are no sealants with equally good adhesion to both materials. This leads to the formation of cracks between window block and a plaster layer.

The last two drawbacks can be eliminated by insulating the opening with penoplex before plastering and using an adjacent window profile with reinforcing mesh.

To make them, pieces of gypsum board of the required size are used, which are screwed to a profile frame or glued to the sides of the opening. Then the surface of the drywall is primed, puttied and painted. The space between the wall and the new slopes is insulated with polyurethane foam.

Attaching gypsum boards is easier and faster than creating a flat surface with plaster. But we must not forget that after installation, finishing is required, which will take several days.

Advantages of using drywall:

• Low cost.
• Easy to install. Requires very basic construction skills.
• The ability to easily create perfectly smooth surfaces.
• Additional insulation.
• Simple repair, suitable for repeated repainting.

• Inability to firmly bind the slope material and the PVC frame (as with the plaster version). This leads to the appearance of cracks at the joints.
• Fear of moisture. If the windows “cry”, under the influence of condensation the drywall, even moisture-resistant, gradually collapses and swells near the frame. Judging by the reviews, this main reason refusal to use gypsum boards in the manufacture of slopes.
• Risk of sagging and squeezing. Still, drywall is a fairly fragile material.

To avoid the stage finishing, you can take laminated gypsum board instead of the usual one. But in this case, you will have to use special corners to cover the ends of the sheets.

The technology for installing slopes made of gypsum fiber boards is practically no different from attaching plasterboard; the advantages will be the same. At the same time, GVL does not have the disadvantages of GCR: it is much stronger and stiffer, and its moisture-resistant version is not at all afraid of a wet environment.

Mr. Build believes that when installed correctly, gypsum fiber board slopes are superior to other options in terms of performance and appearance.

Advantages of gypsum fiber slopes:

• Fairly simple installation.
• High strength and rigidity.
• Possibility of high-quality insulation.
• Ideal design geometry.
• Long service life - at least 10 years.
• Maintainability: a damaged element can be easily puttied and tinted.
• Moisture resistance.

• Relatively high price (compared to gypsum board and plastic).
• The need for finishing.
• Cutting gypsum fiber is somewhat more difficult than cutting drywall.

If, after priming and puttying, you paint slopes made of high-quality gypsum plasterboard latex paint, then they can be washed without fear. And repainting will be required no earlier than after 5–8 years.

Another way to get aesthetic and reliable slopes is to cover the opening with double-sided sandwich panels. They have not only good thermal insulation properties, but also sufficient rigidity.

It is not recommended to use one-sided sandwich panels and decorative panels for finishing a window opening. wall panels made of thin cellular plastic. They do not have the necessary strength, wear resistance and thermal insulation qualities.

Plastic finishing is gaining increasing popularity. The material of the slopes not only visually harmonizes with the window frame made of PVC, but is also securely fastened to it using special sealants. This method of finishing the opening has other advantages:

• Low price.

• A smooth surface that retains its properties for many years and does not require additional finishing or regular maintenance.
• No cracks or temperature changes due to the use of the same material from which the frame is made.
• Additional thermal insulation that strengthens the weak point of the window opening - the seam between the frame and the wall of the room.

• Fast installation. Plastic slopes are installed faster than plasterboard and especially plaster ones.
• Minimum amount of dirt and dust when facing with plastic.
• 100% moisture resistant.
• It is possible to replace part of the slope if damaged.
• The frame covering the outer contour reliably protects the junction of the wallpaper and the window opening.

• Susceptibility to mechanical damage.
• Impossibility of local repairs. If it breaks, you will have to replace the entire panel.
• Low quality of additional elements, such as corners. Often these small parts are made from recycled plastic, which turns yellow over time and stands out unattractively against the background of snow-white slopes.

• Incompatible with interior. Glossy plastic will look unnatural in a room decorated in a classic style, as well as in any other design direction where natural materials are used.

To avoid adding others to these disadvantages of plastic slopes, you need to choose the material wisely, guided by two main rules:

1. Panels must be made from virgin plastic. Only such products are absolutely harmless even when heated in the sun and will not turn yellow after a year.
2. The PVC layer must be thick enough. This will help avoid damage to the slopes.

When choosing between matte and glossy plastic, you need to take into account that stains and fingerprints are more visible on a glossy surface. Matte panels look more natural and are similar to classic painted slopes.

All slope finishing options have pros and cons. No ideal material, which would be better than the others in every respect. Therefore, when choosing, you need to decide which properties and characteristics are more important in a particular case.

Every man who has done home renovations knows that you can lay tiles, install doors, or paint the ceiling yourself and save a decent amount of money on this, rather than giving it to workers as payment.

You may not be able to install a double-glazed window alone, but with slopes things are much simpler. If you do the math, your savings will be about 25%, which is quite a lot. Slopes are a necessary installation element after installing new windows. Even with professional work, traces of damage to the window opening remain, and they must be repaired in order to maintain an aesthetically pleasing appearance. Best season for their installation - summer, since installation work in most cases must be carried out from the street side.

What is the best material to make window slopes from?

Using plaster

Most cheap option get rid of the untidy and sloppy appearance of windows - plaster. It should be immediately noted that it is best to use this method if you have undertaken a thorough renovation of the apartment and have not yet hung wallpaper in the room. Otherwise, traces of plaster or putty will remain on the wallpaper and you will have to re-glue it. Think over this moment in advance, save yourself from unnecessary work.

Photo from the site:

When choosing plastering materials, it is important whether the slopes for windows will be installed outside or inside. If the humidity in your home exceeds the norm of 30-60% (use a hygrometer to measure this indicator), then it is best for you to use a cement base or special plaster for facades (sold in any hardware stores). Use a gypsum, cement or lime-gypsum base if you are installing slopes from the inside.

If you use gypsum plaster, then you can do without reinforcement of the upper slope. If you are using another poorly adhering base, it is better to do it on galvanized mesh, this way you will increase the likelihood that the applied layers will adhere tightly immediately after application.

When applying, use a small spatula. When aligning layers, use the trapezoid rule.

Important to know

Plaster is not durable material. Over time, traces of cracks and destruction appear on it, both on the top layer and in the internal ones. Therefore, in a couple of years you will need restoration again.

Tips for finishing slopes with plaster

• Pre-protect the window frame from contamination by covering it with some material
• Nail a couple of planks on different sides to guide you and apply the finished mixture evenly.
• Prepare the plaster according to the directions and recommendations on the package. Use a bucket partially filled with water room temperature, and a special attachment on the drill for mixing to obtain a homogeneous mass.
• Thoroughly clean the window surface from traces of dirt and level the rough surface.
• Apply the plaster in several layers, each of which must first be left until completely dry. In this regard, the finishing time varies from 2 to 3 days.
• The last movements should go in the direction of the light: from the window into the interior of the room.

Using drywall

This method is faster and less complicated than the previous one.

All work consists of several stages that follow one after another in sequence:

1. installation of the frame;
2. laying drywall;
3. priming before putty;
4. putty;
5. priming before painting;
6. painting.

At its core, this material is gypsum, which is enclosed on both sides between cardboard sheets.

How to make plasterboard slope on one's own:

1. Take the profile corner and cut it into pieces according to the width and height of the window. Then form a rectangle from these beams and attach along the edge window profile using the required number of euroscrews or self-tapping screws. Don’t worry about the appearance, a little later we will hide them under drywall.
2. Pre-calculate all the same parameters we need, then cut out the plasterboard blank. Fill part of the slope with insulation (mineral wool is suitable). The inner edge of the panel with the cut corner will be attached close to the corner. Glue the other edge special glue to the slope. Drywall is divided into three types: waterproof, fireproof and regular. Most the best option when choosing a material, moisture-resistant plasterboard from Knauf or Gyprok is used. When choosing thickness, note that the best range is from 9 to 12 millimeters.
3. Use sealant and attach at the junction of the side and top panels perforated corner. Then seal the resulting joint near the window, and thoroughly putty the entire area of ​​the slope. After sanding, coat it with a deep penetration primer and paint it with waterproof PVA paint. Ready!

Use of plastic

The best option today is plastic slopes. Why this particular material? The one-piece design that results from the work fits into any interior and looks most harmonious in comparison with other types of slopes.

Advantages of plastic slopes:

• Inexpensive cost;
• Long service life of the material;
• You can choose a color scheme that suits the decor of your room;
• Speed ​​of execution installation work. In 3-4 hours you can easily handle the installation;
• Plastic is easy to clean, so it is easy to care for and keep clean.

Plastic also has its disadvantages: if you have a hole or crack in it, you will need to make complete replacement slope You should also be aware that this material is very easily affected by temperature, so extremely high thermal exposure must be avoided.

After installing the double-glazed window, the polyurethane foam will harden completely within 36 hours. Once this time has passed, you can safely install window slopes.

When purchasing plastic slopes, pay special attention to thickness. The minimum thickness should be 8 millimeters. Next, correlate and calculate all the parameters of the plastic (length, width, height) based on the data of your window opening.

What we need:

• F-stripe equal to the length of the plastic panel.
• Plastic panel. The parameters are calculated from the height and latitude of the slopes
• Insulation. You can choose any, but mineral wool is most often used.
• Small wooden block. We will attach it to the sides and tops of the slopes.
• Dowel-nails and self-tapping screws. You will need them in order to attach wooden planks, as well as fix the starting profile
• Silicone. In order for it to look natural, it is best to choose it according to the color of the panels.

Polyvinyl chloride (PVC) is widely used in many industries: construction, toys, furniture, industrial products, etc. Its advantages compared to metal are that it is not subject to corrosion, and compared to wood - to rot. Compared to other materials, it is durable and, if handled with care, can last you for decades.

1. Calculate the parameters of your window and make blocks of wood of the appropriate length. Once you secure them on each side, use a drill to drill holes into which you will screw the screws.
2. Log out
3. Use a pencil to mark future holes into which we will then insert dowel nails. Using a level with two ampoules is the easiest way to level the block.
4. After marking, we make the necessary holes and insert the dowel plugs and secure the block, once again checking that everything is level with the spirit level.
5. Install an F-shape (shaped like Latin letter F) profile on the block. To do this, use a sawing object (knife, saw, grinder). Also cut out the profile parts for the side slopes. In order to get straight ends, use a tray for cutting boards, which is called a miter box. We will calculate the length we need using the formula: the length of the plastic slope + the width of the part of the profile that will line the slope + we leave 20-30 mm in reserve. Having measured the length that suits us, we cut what we need.
6. We measure from the lower profile the length corresponding to the distance from one edge of the slope to the other. From the part that remains with us, we cut off the strips intended for winding this profile. Next, we use a stapler (construction) and attach the strip to the block.
7. We measure the length of the top strip in exactly the same way as in point 4 and secure it again with construction brackets.
8. We need to accurately calculate the 45 degree angle and cut it off in order to later use it at the junction of vertical and horizontal stripes.
9. One of the last moments before installing the slopes is the installation of the starting profile. Install it using self-tapping screws to the window profile. Pre-mark to avoid unevenness. With a pencil we draw lines at the angle we need.
10. Using our drawn line, we again attach the strip to the profile using self-tapping screws and carefully trim the ends. As a result, you should end up with a structure whose joints fit almost perfectly together; you should not have any difficulty in connecting them.
11. We insulate the empty space between the F-shaped and starting profiles using mineral wool and also install the panels.
12. At the end of the work, be sure to go through all the joints and coat them with silicone. In this way, we will kill two birds with one stone: 1) the tightness will not allow air to pass through the holes, 2) the external attractiveness will be preserved and brought into proper shape.

Please note

If you have never installed a slope before, then for the first time try to find someone among your friends who will help you master this business. This way you will protect yourself as much as possible from failures, and besides, together you will get the job done much faster.

Video “How to install slopes on plastic windows yourself”

If you decide to go ahead and seal the slopes yourself with plasterboard, plastic or putty, then we advise you to watch this video, in which you can clearly see how to make slopes on a window using improvised means.

After installing the plastic windows, the slopes are installed. Proper implementation of this activity affects the subsequent thermal insulation of the room. But how to finish the slopes for the windows inside? Today there are many materials with which you can professionally finish slopes. Let's look at slopes made of sandwich panels, plasterboard, and PVC.

Drywall

Many people have a wrong idea about drywall. They believe that it is a profile structure to which a sheet is attached. At the same time, not many people understand how it can be connected to the window system. Therefore, the question related to how to make slopes on plasterboard windows with your own hands is very relevant for non-professional builders.

Organizational process

As a rule, slopes are installed immediately after changing window systems, so the surface should already be prepared.

If the place where the slopes will be located has not been prepared, then it needs to be processed independently, having first removed the remaining plaster from the surface. After which the walls must be treated with a primer in order to improve adhesion.

Drywall slopes - fastening

If the layer of plaster is dense and difficult to remove, then it does not need to be removed, but only if this does not interfere with installation. And to improve its strength, impregnate the plaster with a layer of primer.

Selecting materials

1. The operating time is already finished product largely depends on the material that will be chosen.
2. Since there is a constant temperature difference and high humidity near the window, then it is better to make slopes from moisture-resistant plasterboard.
3. Primer is an important component that plays an important role in the installation of slopes. It will also prevent the formation of fungus or mold.
4. The drywall will be attached to the planting gypsum. Therefore, it must withstand temperature changes, which will create warm slopes for plastic windows, and have moisture-resistant characteristics.

Taking measurements

When installing slopes after installing plastic windows, measurements are very important. Let's look at how to take measurements in more detail.

Slopes for plasterboard windows

1. The first thing you need to do is measure the distance from the edge of the wall to the window.
2. Then you need to measure the distance from the wall to the middle of the window, which sets the slope angle. Thanks to this we get legs.
3. Next, you should square the length of each side of the triangle, and then add everything up. The square root is taken from the resulting number. As a result, it will become the value of the width that the future slope should have. The length of the panel is measured with a tape measure.

Remember: it is simply necessary to make such calculations. If this is not done, then the result will be visually crooked openings and uneven windows. And to make accurate and quick calculations, use a calculator, thanks to which you can easily extract square root without using special formulas.

Installation

Before installing the slopes, markings should be made, which should be equal to the distance from the wall to the window. Then it is applied to the frames on which the slope will be located.

After this, according to the instructions on the packaging, planting plaster is diluted. The mixture is applied with a spatula to the wall in order to obtain 3.4 points of contact between the drywall and the wall.

Next, you can begin installing window slopes made of plasterboard, which includes gluing the sheet using planting plaster. At the same time, the edge near the end of the wall must be held tightly, and the edge located at the window is equal to the markings.

Installation of slopes for plasterboard windows

Remember: when adjusting slopes in the markings, it is better to use a level, thanks to which you can easily monitor the curvature of the surface.

Final works

When the putty dries, paint for the window slopes will come in handy for additional protection.

PVC panels

For those who are still puzzling over how to seal the slopes after installing plastic windows, we can offer another worthy variation - PVC panels.

Installation of PVC slopes is divided into several stages. Let's consider each stage separately.

Surface preparation

After a day has passed after installing the balcony block, you can proceed to installing the slopes. First, remove excess foam that appears between the profiles at the joints and the wall with a stationery knife. Afterwards, the surface must be cleaned of any remaining small debris.

Slopes for PVC windows

Initially, using a tape measure, you should calculate the parameters of the profiles along the visible edge. Moreover, it is necessary to calculate their outer width, and also find out the distance from the top of the window to the bottom. It should be noted that this process can be made easier if you completely remove the frames or at least bend the film back a little.

To install PVC slopes for windows, use P- shaped profile, suitable in width, it is cut into pieces. For these purposes, use special scissors designed for cutting metal sheets. Then the profile elements are attached at a distance of 20 cm with screws to the outer part of the frame. Identical manipulations should be done with the side and top surfaces.

Installation of sheathing

To assemble the sheathing, wooden slats are used (section 2*4 cm), which are attached to the side and upper corners of the slope. To fix the slats, dowels are used, the distance between which should be approximately 30 cm. If you want the perfect lattice, use a plane; thanks to this tool, you can flawlessly adjust the thickness of the slats. Finally, check their levelness using a building level.

Installation of the upper slope

How to repair slopes after installing plastic windows yourself? First, you should determine the length of the external slope, and then cut an element of the required size from the PVC panel. It is better to work with the material using a jigsaw, but the cutting must be done extremely carefully. Next, the panel is attached to the top profile and sheathing with self-tapping screws.

Installation of side panels

Side PVC profile mounted in the same way as top bar. The space that appears between the wall and the panel is filled with polyurethane foam. For this purpose, the outside of the product is wetted, and then foam is applied to it. Such work continues until all free space is filled with material. A PVC panel is attached next, and do not forget to ensure their evenness using a level, and also secure them with self-tapping screws. The relationship between slopes and angles is controlled by a tool called a malka.

Slopes for plastic windows

Installation of F-profiles

At this stage, the installation of plastic corners is carried out, during which the product of the required size is cut, and then it is inserted onto the panel along the edges. In those areas where the corners come into contact with the screws, inside A small cut should be made at the corner.

Final stage

At the end, the joints are finished using a slope sealant or a profile mixture of a suitable color. The composition is applied to the joint cut and then gently pressed. Remains are removed. The sealant will protect the product from dust, moisture, and debris.

Sandwich panel

When installing slopes from sandwich panels, builders use 3 main materials:

• foam;
• liquid nails;
• wooden beams.

Foam installation is the easiest option. However, in this case it is necessary to purchase sandwich panels that have a rigid frame. This process is done like this:

• taking measurements;
• cutting the frame strip;
• frame assembly;
• fixing the frame between the upper slope and the window sill;
• cutting panels;
• inserting panels into the frame.

Foam

First, 2 side slopes are assembled, and at the end - the upper one. Before blowing the system with foam, you need to measure the slopes with a level, and also install spacers so that the swollen foam cannot move the frame.

Slopes made of sandwich panels

This method can only be implemented if two-layer sandwich panels are used. To improve adhesion, before blowing out the cracks, the wall of the room and the inner plane of the panels should be sprayed with water from a sprayer.

After a day, the foam will harden, then it will need to be trimmed. Next, overlays are put on, which perform a decorative function. Sometimes installers carry out this process immediately, but this is not compatible with technical rules.

Liquid nails

They will be appropriate only if the walls are in good condition. Thanks to liquid nails, you can avoid using the frame and install it directly on the wall.

This method is suitable for spacious windows, where a lot of plastic will negatively affect their appearance. The process is divided into the following stages:

• measurements;
• panel trimming;
• preliminary fitting;
• leveling the surface (plastering, removing old materials);
• gluing the panel.

Initially, the outer panel is attached, and the side panels are adjusted to it. But after that there are 2 unresolved problems:

• seams in adjacent areas;
• open end element.

I seal the seams with a simple putty mixture that matches the color or with silicone, provided that the plastic is white. Today, acrylic paint is increasingly used for such work; its texture is similar to PVC coated, thanks to which you can create a good appearance.

Slopes made of sandwich panels for windows

The end can be covered with a layer of plaster. And if the windows are located over the entire surface of the wall, then you won’t need to think about what and how to paint the slopes on the windows inside. In this case, the end is painted with white paint, but it should be noted that the sandwich panels must have an identical color. You can also just hang wallpaper.

Wooden blocks

To reduce foam costs during the installation of difficult, damaged slopes, wooden slats are used, which are the basis for attaching the frame. The technology of this process is as follows:

• taking measurements;
• beam trimming;
• assembling a quadrangle to which sandwich panel strips are attached using a stapler;
• trimming and subsequent insertion of panels into the base;
• foam blowing;
• after 24 hours, all excess is removed;
• installation of overlays.

Window slopes made from sandwich panels are particularly resistant to mechanical defects. Give preference to 3-layer panels, because 2-layer panels are not rigid enough. However, this condition is not necessary.

To complete the installation of the front door or windows, you need to finish the slopes. A door or window slope can be made using plaster, drywall, and plastic panels.

The most common option for facing slopes is plastic panels. Because finishing window slopes inside with plastic is a universal solution. It should be noted that this building material is used for interior and exterior work.

Advantages of plastic

To cover the slopes of a house, the plaster method was previously used, then plasterboard, which was widely used for cladding. But with the advent of PVC windows, plaster and drywall faded into the background. Since finishing slopes using the plaster method has significant disadvantages. The main disadvantages include:

• If you plaster the slopes yourself, it takes a lot of time.
• This type of finishing creates a lot of construction waste.
• Due to shrinkage and temperature changes, cracks may occur on the surface.
• The component elements do not form the required adhesion to the plastic, as a result of which the slopes peel off from the window.

Internal window slopes made of plastic

To properly plaster the window opening, you should use a perforated corner and beacons. The perforated corner is installed on the outer corners of the slope. To do this, you need to cut off a corner of the required size, apply putty to the slopes and press the perforated corner. The plaster beacon is installed vertically along the window frame. To do this, cut the beacon to the required size, apply putty along the box and attach the prepared parts. After 40 minutes, you can plaster the slopes.

A finishing material such as drywall provides the opportunity to make slopes faster and warmer. But even the moisture-resistant version of this material cannot withstand temperature changes and the influence of condensation. PVC window slopes have a more interesting appearance.

Advantages of plastic slopes

But beauty is not their only advantage; positive characteristics include:

• The panels are made of the same material as the window frame, hence the window space n The premises acquire a monolithic structure.
• It is enough to simply install the insulation. It should be noted that with proper insulation, condensation is impossible.
• Installation of plastic panels creates virtually no debris or noise.
• This kind of building material can be used externally and internally, since polyvinyl chloride does not emit harmful substances.
• Insensitive to moisture.
• Duration of use.
• Tolerates temperature changes perfectly.
• Easy to use.
• The building material has an excellent pricing policy, therefore, it is available to anyone who wants to install plastic window slopes with their own hands.

The disadvantages of plastic include the impracticability of fragmentary restoration.

Do-it-yourself plastic slopes for windows (video)

Selection of building materials

Before you think about how to make plastic slopes yourself, you need to consider possible variations in materials. There are 2 types of plastic panels:

1. Decorative.
2. Sandwich panels.

Decorative slopes can be used:

• For the formation of partitions.
• As a facing building material for balconies.

Necessary tools for finishing window slopes

For all other purposes, preference should be given to sandwich panels. This kind of material differs in that it has 2 protective layers and a facing layer of insulation. This structure allows you to avoid additional insulation. Key Points panel selection:

1. Preference should be given to building materials made from virgin plastic. Since the correct material is chosen, it will not change color, and the composition will not cause damage to health.
2. It is better to choose a material with a significant plastic cover. Panels with thin PVC sheet covering are not durable. Over time, the plastic peels off the surface.

Finishing window slopes with plastic requires the following materials:

• Profile.
• Self-tapping screws.
• Dowels.
• Wooden slats.
• Gypsum insulation wool.
• Liquid nails.

Preparatory moments

Removing polyurethane foam residues

To finish the inside of window slopes with plastic in a high-quality manner with your own hands, you need to clean the walls and prepare all the necessary equipment and building materials. To form slopes, the thickness of the plastic strip should be 8 mm. The width and duration of the plastic must correspond to the size of the opening. You should prepare and clean the walls step by step:

1. Remove excess foam.
2. The shipping tape must be removed from the window profile.
3. Seal the internal seams.
4. The upper reaches and side sections of the hole must be freed from whitewash and leveled with putty.
5. It is recommended to wipe the prepared area and apply 1-2 layers of primer.

Technologists I formation and installation

After preparing the opening around the circumference, you should glue vapor barrier film. At the combination points, sections of the film should be laid with an excess of 5-7 cm and glued along the seam. The tape must be glued so that the edges do not extend beyond the window frame. After this, you can proceed to the formation of slopes using the following instructions:

We fasten the bars with dowels

• Fastening timber material. For these purposes, wooden slats with a thickness of 15 mm and a width of 40 mm are taken. The slats should be trimmed to the width and height of the outer edge of the opening. The slats need to be secured with dowels around the circumference of the opening. If the walls of the hole are wavy, then it is recommended to place wedges under the planks.
• Take the necessary measurements carefully. It should be understood that all measurements must be taken from the frame, and not from the edge of the special profile.
• Open the slopes. The length and width of the walls of the hole should be correctly measured, and attention should be paid to the angle of inclination on each side. You should mark the cutting points on the slab and cut out the workpieces. The resulting elements should be attached to the wall and their location and angular fit should be checked.
• Special profile fastening. A special profile should be attached along the outer edge of the opening with short screws. When joining the bars together, the special profile should be secured in the corners so that no gaps are formed. Installation of slopes begins with the manufacture of edging. This structural component is made from an F-shaped profile. All manipulations should begin from the top element. The profile must be cut to the size of the external opening and the corners must be filed at 45 degrees. The prepared special profile should be attached to the block so that it can be covered with plastic, but without blocking the groove for fixing the slope.

Installation of plastic slopes

• The profile is fixed to the beam with staples. The remaining sections are mounted in a similar way. The prepared slope element must be placed in a special profile, pre-coated with sealant. The resulting gap between the plastic and the wall must be sealed with insulation. It should be noted that the layer insulation material should not be overly massive or have vacuums. The outer edge of the slope must be inserted into the groove of the special profile and pressed to align the panel. Next, you should sew up the side slopes, while carefully distributing the thermal insulation. If external walls insulated, then such manipulations with the slopes need not be performed. In such a situation, the gaps between the panels and the base of the slopes should be sealed with polyurethane foam.
• The final period involves attaching decorative corners, which should be glued with glue. The contact points between the panels must be degreased and all cracks must be sealed. acrylic sealant. Acrylic should be squeezed directly into the gap, rubbed and leveled, and any excess should be removed with a damp cloth. All manipulations should be done in small areas and wiped carefully clean. Because while the acrylic has not hardened, it can be removed quite easily. The area of ​​the opening under the window sill is being plastered.

PVC slope cladding

Advice! You can veneer window slopes in another way, which differs significantly from the previous one. This method allows you to cover a window slope using any PVC material. It should be noted that this option is used when the installation seam has a small interval, that is, the distance from the frame to the wall is minimal.

The initial stage should be carried out in stages:

• Cleaning.
• Elimination of defects.
• Applying primer.

Sheathing slopes should adhere to the following rules:

1. Remove excess foam, making sure that the cut is placed flush with the surface of the frame.
2. Facing slopes with plastic plates involves treating the surface with a primer. Preference should be given to penetrating formulations with the addition of antiseptic components.
3. Fixing slats.
4. An important point is trimming the polyurethane foam. The cutting is done in such a way that a groove is formed for fixing the plastic. Trimming is done in close proximity to the frame to ensure maximum adherence of the material.
5. Reveal the details.

Window slopes lined with PVC

After the manipulations have been performed, a number of actions should be performed:

• Using a jigsaw you need to cut plastic. As a rule, burrs may remain along the edges, which can be removed with sandpaper.
• Performing preliminary installation. This manipulation will allow you to determine the presence of defects. If double-sided plastic is used for cladding slopes, then one side needs to be sanded a little, thereby indicating the wrong side of the material. Carrying out such manipulation promotes better adhesion. Since PVC panels are fixed using polyurethane foam.
• The prepared elements are placed in the right place. They need to be installed in the prepared groove. Using a level, the structure is leveled.
• The outer edge of the part is moved back and foam is poured into spots.
• All structural parts are attached to each other using masking tape. Fixation is carried out along the circumference of the structure and at the joining points.

Important! Beginners have a question: how long will it take to completely dry? As a rule, it will take a day for thorough drying. After which additional finishing activities are carried out. It should be remembered that external slopes also require attention.

Quite often, siding is used for such purposes. Working with building materials does not cause any particular difficulties due to the characteristics of the material. But if difficulties arise, then on the RuNet there are many videos and photos with detailed instructions regarding the installation of siding. The simplicity of installation work will allow you to do the cladding yourself.

Photo gallery of finished works

The final stage of window opening design is finishing the window slopes inside.

This is not only the aesthetic side and completeness of the interior, but also the replacement old plaster, which allows you to make openings more reliable with improved thermal insulation.

If the slopes are made with high quality, their heat and sound insulation properties will only improve. You should not postpone this procedure until later, as this can lead to unpleasant consequences:

• Thermal insulation may be damaged by sun rays on construction foam, which is usually used to process openings;
• If the foam layer is not treated, it will draw moisture into itself, thereby destroying the structure during the cold period;
• Cracks may appear due to an increase in the volume of foam;
• Drying of the polyurethane foam leads to the fact that it begins to crumble and gradually loses its thermal insulation properties.

Slopes can be finished various materials: laminate, wallpaper, wood, parquet boards, cork, decorative plaster. The base should be selected in accordance with the design of the room and the material of the window opening itself.

Light finishing requires the use of light materials, which cannot be said about heavy types of cladding, for example, tiles. Here you should prepare a cement-gypsum base.

Let's look at the most popular options.

Plastering

This method can be called the classic finishing method. It will require following materials and tools:

• Cement;
• Sand;
• Starting putty;
• Finishing putty;
• Water;
• Primer;
• Roller;
• Level;
• Water-based paint;
• Dye;
• Sandpaper (fine grain).

Work should begin after 36 hours so that the foam adheres well to the openings.

The window is cleaned of old plaster, paint, wallpaper and dust. A layer of mortar is applied to the walls, then to the slopes from bottom to top. A solution is prepared from sand, cement, water and the first layer of plaster is applied where a large amount of the mixture is required.

Apply each subsequent layer after the first one has completely dried. The thickness of each application should not exceed 7 mm.

Afterwards, the surface is rubbed down with fine-grained sandpaper and you can proceed to painting it with water-based paint, which can have any color using dye, according to your design.

You can also wallpaper it. The good thing about this method is that it is the basis for any type of finishing. But there is also a drawback: the solution made of sand and cement has an unreliable connection with the PVC frame material, which can lead to cracks.

If we talk about thermal insulation properties, they are weak and will ultimately lead to the formation of condensation and mold. To prevent this from happening, it is necessary to additionally install a layer of insulating material.

Drywall

Moisture-resistant material is mainly used when finishing slopes inside, since it is resistant to condensation on the window and is characterized by thermal and heat-insulating resistance.

Sheets of material are attached to a prepared sheathing (metal or wood). The surface should be pre-treated with a solution if there are strong potholes.

Assembling the slope begins with the panel located on top, its edge is coated with glue and inserted into the starting strip. The second end of the drywall should be pressed against the wall. This procedure must also be carried out with the side panels. Here it is mandatory to treat the joints with a neutral sealant.

To extend the life of corners, you can use paint corners.

The last step is to use putty and apply acrylic or oil paint to it.

Decorative stone

Natural stone is used quite rarely. There are reasons for this. First of all, it's heavy. Secondly, it is expensive. Therefore, an excellent analogue is decorative stone. They are used to finish door and window openings, and you can handle this work yourself.

Decorative slabs 2 cm thick are selected. An area is prepared for attaching artificial stone (plastering). Notches are made on the surface for more reliable fastening glue is added and treated with a primer.

Then, after drying, glue is applied to the slab or wall and the stone is fixed. You can also use liquid nails. The work is carried out using a building level.

Laying is carried out in horizontal rows from bottom to top. If necessary, trim the stone.

Plastic, laminate and parquet boards

The use of plastic is the most common processing option, since its distinguishing characteristic is durability (15-20 years).

It is convenient to install it for several reasons:

• Work can begin on the same day;
• Plastic panels are an additional heat-insulating barrier between the room and the street;
• High moisture resistance;
• The homogeneity of the material of the glass unit and the slope allows working synchronously during temperature changes;
• Does not fade;
• Cleans well, does not sweat;
• Does not need painting;
• Has an attractive appearance.

Technical features of the material allow you to make slopes various forms– bay windows, arched and round.

This finishing method deserves attention, as it looks original. There is one problem with working with laminate boards: they crumble. Therefore, you should decide in advance how to hide the corner joints.

Finishing can be started from top to bottom and vice versa. The difference is noticeable only in the direction of the grooves of the lamellas. Fastening is done with self-tapping screws, each subsequent lamella covers the groove of the other, due to which the fastening points remain invisible.

Parquet boards are quite easy to saw, since the base is wood. Laminate or parquet boards can be mounted on drywall.

Finishing the slopes inside and outside should be done simultaneously. Work is carried out at a temperature of 20-25 degrees.

To improve the quality of slopes, they need to be insulated. For an opening finished with plaster, it is better to use paint as the last layer - this will increase its moisture resistance.

Finishing window slopes inside the apartment

Architects creating their masterpieces great value were given to windows as the final stage in the formation of an architectural ensemble. Sizes, shapes and functional purposes have changed over time and the requirements of architectural fashion.

Architecture improved, and along with it, windows became the dominant decorative motif of the wall. Having absorbed the variety of styles inherent in a particular era, the windows acquired a laconic appearance and a classic shape. This element of architecture is decorative in nature and surprises with its functionality.

Plastic windows have been prevailing over their wooden counterparts for a long time. Therefore, finishing the slopes of plastic windows and their installation does not lose its relevance.

Types of materials

More recently, plastering of slopes has been in use. At the same time, the adhesion of plastic and plaster was not very good. Very often, the seams cracked; due to temperature changes, the entire surface of the window cladding cracked. hydro-, heat- and sound insulation was violated. At the same time, plastering is a complex and lengthy process that requires patience and accuracy.

With the help of modern developments, the finishing of window slopes inside is presented in several types, which involves choosing based on the positive aspects of the materials.

1. Panelite is a cellular panel made of PVC with an internal polystyrene foam filler. It is used at a depth of no more than 25 cm. The joining of this panel with a deeper window opening loses its presentability and also changes color over time. Due to its low weight, finishing the windows inside does not pose much of a hassle. They have increased resistance to mechanical damage.
2. Adhesive plastic is attached using glue. It has a number of disadvantages: peeling as a result of temperature fluctuations, and condensation forms when freezing.

Sheets of plasterboard as a finish have good thermal insulation, are environmentally friendly, and can be painted in any color. Disadvantages: when high level humidity causes cracking and destruction of the integrity of the plasterboard structure.

Sandwich panels are made of polymer plastic and are the most reliable option for finishing window openings: providing thermal insulation, color preservation, easy to maintain, and durable polymer coating, aesthetic appearance, reliability and durability during operation. With the right choice of insulation, sandwich panels are fire resistant. Sheet plastic is of high quality, excellent thermal insulation, and exact color match to the window frame. The disadvantage is the high cost.

With all the diversity, it is worth taking a responsible approach to the choice of materials, taking into account all the listed factors, first how trim window slopes inside .

How to choose the right slopes for plastic windows, read our article “Choosing the most “correct” slopes for plastic windows.”

Finishing window openings inside with plastic

High-quality covering of window slopes with plastic after completion of installation will save you from many unpleasant consequences. It is designed to ensure heat retention in the room, sound insulation and moisture penetration.

Finishing window slopes inside with plastic has numerous advantages. Defining parameters:

• aesthetic appearance;
• Duration of operation provides economic benefits;
• damage-resistant material;
• functionality.

In addition to the main characteristics, it is worth paying attention to the technological qualities of the slopes:

• presence of stiffeners (panelite);
• the content of foam insulation (sandwich panel) ensures greater heat retention in the room;
• preventing condensation formation;
• sealed;
• correct installation hides defects;
• the interior decoration of the windows looks symmetrical and smooth;
• large color palette;
• a lamination procedure is possible to create a textured structure;
• matte and glossy surface;
• dust-repellent surface,
• comfort and ease of care;
• ease of installation of the structure.

High-quality finishing of the internal slopes of plastic windows guarantees durability.

Required tools and materials

Interior finishing of plastic windows requires some preparation in terms of acquiring the necessary materials and tools:

• level;
• drill;
• construction knife;
• calculator (for comfort when making calculations);
• F-profile;
• stapler;
• mineral wool (spray foam, ponoizol);
• silicone (sealant, liquid plastic);
• staples;
• antifungal agent (primer, fungicide);
• self-tapping screws small size(“bugs”);
• plastic;
• choppers and slats (plastic, wood);
• masking tape;
• degreaser (alcohol, acetone).

How to do interior window decoration yourself

In order to finish openings. It is not necessary to resort to the help of qualified specialists. The easiest way, which is completely doable, is to decorate the windows with plastic with your own hands. It is enough to follow the rules and veneer the window opening step by step.

Having purchased and prepared all the necessary materials and tools, you can enthusiastically begin lining the window slopes with plastic.

1. Preparing for work:

• carefully cut off any remaining foam that protrudes;
• remove paint and old plaster;
• treat with antifungal agent.

1. Panel cutting:

• take accurate measurements;
• put markings;
• cut at an angle of 45°.

1. Installation:

• secure the cut panels around the entire perimeter of the window opening using small self-tapping screws;
• carefully join at the corners;
• if there is a slight discrepancy, adjust the design;
• maintain a gap of 3 cm between the base of the slope and the plastic structure.

1. Filling voids:

• fill the perimeter between the old and new slopes with installation foam (mineral wool, penoizol);
• fill with foam should not be a continuous line, but with small intervals.

1. F-band installation:

• F-profile corners cut at an angle of 45°;
• to fix the slats, use choppers made of wood or plastic;
• Attach the profile with grooves to the end part of the plastic panel using masking tape.

1. Finish:

• degrease facing seams at the junctions;
• fill them with sealant.

As a rule, finishing plastic windows inside takes no more than 3-4 hours, even without experience.

Reasons why you need to trim the windows in your home

The completeness and neatness of the window are created by slopes, both inside the room and from the outside, and also carry a number of functional loads:

1. external:
   • protection against destruction of polyurethane foam,
   • prevent moisture from entering,
   • thermal insulation,
   • maintain sound insulation,
   • protection from ultraviolet rays.
   • I ensure reliable adhesion of the window frame to the opening.

1. internal:

• decorative component,
• protection of waterproofing materials,
• eliminates condensation.

If the outside slopes are not finished in time, negative consequences will lead to re-installation of the window unit. These are additional costs of money, time, and effort.

How to finish slopes inside a window

Modern glazing technologies imply careful attention to every detail, so questions about how window sills and slopes are designed also do not go unnoticed by the craftsman. Proper repair of these structural elements of the window will provide him with more long term operation and will prevent the risk of cold air entering the home. Let's talk further about how the interior window slopes are finished, and what materials need to be used for this.

The need to finish the slopes inside the window

The relevance of finishing window openings indoors and outside the house with sandwich slabs, plaster, etc., as well as the front door with decorative stone, is very high. Internal factors, the action of which can negatively affect the quality of the window itself and its slopes, include:

• increased humidity indoors;
• the appearance of condensation on the window due to a significant difference in temperature outside the window and inside the house.

External factors that have a destructive effect on the window and its slopes include:

• precipitation, wind, sunlight;
• sharp changes temperature regime ambient air;
• mold, mildew, harmful insects.

Proper finishing of windows and doors with decorative stone allows you to increase the level of durability window design to the influence of the described factors as high as possible. This will ultimately extend the service life of the windows, improve the appearance of window openings in particular, as well as the facade of the house in general. You can see a window with high-quality slopes inside the room in the following photo.

Drywall

Most often, the decoration of indoor slopes and entrance doors is done using plasterboard. This is a finishing material with high performance parameters, which allows you to quickly and with a minimum of effort make slopes perfectly smooth and resistant to external influences.

Drywall is lightweight and its installation on vertical surfaces is not particularly difficult. It is beautifully painted in the current color shade. In addition, such materials, when properly treated with antiseptic compounds, can prevent the risk of mold and mildew developing at the joints of slopes and window frames. Window finishing with plasterboard is shown in the following photo.

Material selection

You should not think that you can choose any type of drywall to design slopes in your house. The material should be selected taking into account its operational parameters. And they differ for different types of drywall, which should be taken into account by the master before materials are purchased and window repairs begin.

Absolutely any window is a source of moisture in the form of condensation, which is formed due to the large difference in temperature in the house and outside. As a result, the materials used to repair slopes must certainly be resistant to this factor. This means that you need to select only moisture-resistant plasterboard sheets, on which the presence of condensation will not have a negative impact. Otherwise, the repair will retain its functionality and attractive appearance for only a short period of time. In addition, it is worth using antiseptic compounds to cover the surface of the material, as well as special paint for its finishing.

Finishing the slopes of plastic windows in a house should always begin with taking measurements, for which you will need to stock up on a measuring tape. The final results of the master’s work largely depend on the quality of this stage of work. If the slope does not fit as tightly as possible to the window frame, there will be a risk of developing such negative consequences, How:

• the appearance of mold and mildew outside and inside the premises;
• the appearance of microcracks through which frosty air will begin to penetrate into the house during the cold season. Gradually, without adequate measures to eliminate the problem, the cracks will grow, and with them the cost of heating the premises;
• reduction in the service life of the window structure, its rapid wear both in quality and aesthetic terms.

Taking measurements

Installation of slopes

Finishing slopes with plasterboard begins with an analysis of the measurements taken. All window parameters are transferred to plasterboard sheets, from which you need to cut pieces that are ideal for the window opening.

Drywall cutting process

Installation of such canvases can be carried out on the lathing, on the profile, or without them. The choice of technology should be determined by the fact in which state the slopes are. Visually evaluate whether they are processed with high quality, as well as what quality the double-glazed window itself has.

Installation of drywall is carried out using a special adhesive composition if the walls are perfectly even. If not, you will need to first bring them to this state.

Next, you need to attach the strip to the window profile or frame, which will securely fix the drywall on the side of the double-glazed window. Plasterboard panels are installed on top of the planks, carefully treating the resulting voids with sealant. Then the structure will be devoid of cold bridges.

PVC panels

No less popular today is the repair of slopes in the house. PVC panels on the profile and doors with decorative stone, thanks to which the entire structure acquires a solid appearance. This type of repair, as shown in the photo below, is different for a long time service and retains its properties for a long time.

Plastic panels are selected taking into account the size of the window opening, as well as its technical parameters. Before starting repairs, you will need to prepare the surface of the slopes. Then, PVC parts of the current size are cut out, which will be mounted around the entire perimeter of the window on wooden slats and profiles.

If you want to insulate the house, the space between the wall surface and the panels should be filled with a layer of mineral wool or construction foam. Finishing slopes with PVC panels on the profile is also beneficial because PVC materials have a smooth surface, are produced in different color shades, looks harmonious in the interior of a private house. This allows you to save on the final painting of the slopes.

Another attractiveness of this method lies in the fact that all elements of the window structure (window, slope) acquire the same expansion coefficient, which will ensure they fit tightly together and prevent the risk of cracks forming.

Surface preparation

To install plastic slabs on a slope, you need to carefully prepare the surfaces. To do this, I carefully cut off the excess mounting foam using a utility knife, and the surface itself is cleaned of dirt and dust, coated with an antiseptic, and primed. Next, you will need to install a metal frame made of guide profiles.

A hairdryer can help remove paint from walls.

Installation of the guide profile

Measure the profile along the outer edge using a construction tape, and then its outer width and the distance from the top edge of the window structure to the surface of the window sill. Take a U-shaped profile of the current width, cut it into pieces using metal scissors, according to the window measurements. Next, the sections are screwed at intervals of 20 cm using screws along the outer part of the window frame. The top and side profiles are mounted in the same way.

Metal profile Installation of starting profile

To organize the sheathing, you will need wooden slats with a cross-section of 20x40 mm, which are attached to the far corner of the slope from above and on the sides with dowels in increments of 30 cm. The sheathing must have perfect evenness, for which the thickness is adjusted with a plane wooden slats and check the work at the construction level.

Panel installation

Finishing with plastic plates can be easily done with your own hands. To do this, cut the material with a jigsaw, then fix it on the upper profile and secure it to the sheathing using self-tapping screws.

The side profile is mounted in the same way as the top bar. And the gaps between the window frame and the wall need to be filled with construction foam, for which the surface is first moistened with water. After this, you need to lean the plastic panel against the base and secure it to it with metal screws.

Fastening PVC panels

Installation of F profiles

The F profile is cut and inserted along the edges of the panels. In those areas where the corners come into contact with the fasteners, you will need to make a small cut. At the same time, the slopes of the front door should be decorated with decorative stone, which looks very expensive. At the end of the work, you need to fill the joints with white sealant, carefully filling the gap with the compound, removing excess volume.

These measures will not only make the window even more attractive, but also protect it from mold, mildew, and rapid wear.

Sandwich panel

Repair of window and front door slopes can be done with sandwich slabs, as shown in the following photo. The window sills and windows are decorated with sandwich slabs, and the door slopes are decorated with decorative stone. Sandwich plate long time retain visual appeal and original operational parameters.

In accordance with all the rules and regulations, repairs of window structural elements can increase the degree of resistance of windows to the negative effects of negative factors inside and outside the house. The distance between the wall and the sandwich plate must be filled with construction foam, which will act as additional insulation for the structure.

Installation of such plates is not particularly difficult. The sandwich plate is fixed to the base using liquid nails, which will provide the connection with high practicality, density, and durability. Check the angles of the slopes for compliance using a small tool.

Installation of sandwich boards must be carried out on wooden blocks, which will make it possible to give the surface of the slope ideal evenness even if there is a deviation of the slope from the vertical. To ensure a neat appearance for the joints of the plates, they need to be treated with silicone.

Plastering

Finishing window slopes outside or inside the house is often done by plastering the surface. But applying this method is only relevant if the slopes are perfectly even. The layer of plaster mass should not exceed 2 cm in thickness, otherwise the slopes will quickly crack and become unusable. This type of finishing goes well with finishing door slopes with artificial stone.

Common mistakes

It often happens that the finishing of window slopes inside is carried out in violation of technology, which entails a number of negative consequences. In other words, these structural elements of the window opening acquire low resistance to the effects of negative factors indoors, which entails rapid wear of the slopes. This is why it is so important to identify the most common mistakes made by inexperienced builders when finishing window slopes:

• incorrect measurements of the base for installation of sandwich or PVC panels, drywall, etc., which leads to a loose fit of materials to the slopes;
• neglect of antiseptic and sealant increases the risk of mold and mildew developing under sandwich panels, drywall and other finishing materials for decorating slopes;
• when using plaster mixtures often inexperienced craftsmen try to correct base defects by applying an excessively thick layer of finishing. And this is unacceptable, since plaster more than 2 cm thick may crack after drying;
• When finishing door slopes with stone, you should not give preference to too cheap material. Decorating even with artificial stone cannot be too cheap, because such savings affect the quality of the finish.
