Where to buy fasteners for plastic windows. Installing a plastic window with your own hands: consider the installation of a plastic window step by step. Window assembly sash adjustment

The decision to replace wooden windows with plastic ones has all the advantages, since modern double-glazed windows are much more functional and reliable. Of considerable importance is the correctness of their installation, for which several methods are used. The most popular of them is mounting on anchor plates.

Most often, one of two methods is chosen for installing plastic windows:

1. Direct screwing of the frame into the opening with screws.
2. Use of anchor plates.

The first option is considered more difficult, because. involves a complete disassembly of the structure, including the removal of sashes (both deaf and movable). This makes it possible to drill the profile without interference, attaching it to the walls of the opening with self-tapping screws. After installing the frame, the window is assembled again: this procedure includes adjusting the sashes, installing fittings and double-glazed windows.

This work is quite laborious, so most beginners prefer the faster second method. At the same time, it is important to remember that constructions with an area of ​​more than 2 m², it is recommended to install only directly (this option is more reliable).

The material for the manufacture of anchor plates for plastic windows is galvanized steel with a thickness of 1.5 mm, for which the stamping method is used. Products are equipped with a series of round holes for mounting screws. For the possibility of pre-assembly bending, the plates are equipped with a guide notch in some areas. The depth of the bend directly depends on the thickness of the installation gap: it is selected at the installation site.

It is most convenient to fix the anchor plates on window mounting screws 40x5 mm. To fix the flexible plates in the opening, you will need plastic dowels and locking screws. Each anchor must have at least two anchor points. Here you will need screws 50x6 mm.

There are three main types of anchor window plates:

• Swivel.
• Fixed.
• For wooden windows.

Rotary products used in those situations when fastening the window block in the opening is difficult for one reason or another. Thanks to the swivel mechanism, the plate is positioned on the part of the wall that provides the most secure fit.

If everything is done correctly (exactly combine the turn signal and the external bent teeth), the product will be fixed as securely as possible. In this case, there is no danger of deformation of the profile. The presence of a rotary element and the ability to bend the element makes it possible to use various mounting angles. Most often, arched, trapezoidal and polygonal systems are installed in this way.

With a simple fixed anchor plate installation of plastic windows inside the opening is carried out, with the possibility of selecting the optimal mounting angle. To improve the strength of fixation, some models additionally have a claw hook.

Concerning anchors for wooden windows, then they are not used to install plastic systems.

The ability of anchor plates to quickly provide a reliable connection between the window block and the wall is their main advantage. As a result of this, it is possible not only to save time and effort, but also to withstand seasonal and daily temperature fluctuations well (this is fraught with structural deformation).

This type of attachment has other dignity :

• Ease of installation. Unlike fastening through the frame, the plates eliminate the need for complete disassembly of the window system. This speeds up the installation work, at least twice.

• Selection of the optimal mounting area. Movable mechanisms allow you to fix the window at the most convenient angle.

• Possibility of installation of the block precisely on level. By adjusting the tension of the side screws, you can achieve precise positioning of the frame in space. In this case, you do not need to put pegs or adjust the openings.

• Quick dismantling. If necessary, the plates are unscrewed and the window is removed. This happens much faster than with through bolts.

• Ability to reinstall the block. Since the profile is not subject to reaming, the window system on plates can be reinstalled in another location.

• Use on walls made of different materials. In addition to concrete and brick surfaces, anchor plates adhere well to wood, foam concrete, gas silicate blocks, etc. They are especially convenient in cases where multilayer walls are used in the house: rod fasteners (screws, anchor bolts) in such situations are powerless.

• Possibility of disguise. Anchor devices open the possibility for the use of platbands, window sills and overhead slopes, well masking mounting gaps. In this case, there is no need to sink the plates into the surface of the slope, followed by sealing the resulting recesses with plaster or putty.

• Fastening reliability. The plates are well tolerated by significant operational loads, including strong wind and kickback during the opening of the wings.

• Cheap fasteners.

Have anchor plates and weak sides :

• Restrictions on the weight of the window structure. Reliability of fastening on plates is guaranteed only for small and medium-sized window units. Heavy structures (most often of a balcony type) are best installed by screwing them through the frames. This also applies to cases where several rows of windows are located on top of each other.

• Danger from frequent opening of the sashes. In this case, the window frame is experiencing additional loads, which may adversely affect its integrity. Those sashes that open very often are recommended to be additionally reinforced with bolt fastening.

• Decoration damage. It is far from always possible to disguise the anchor plate. First of all, this applies to cases of using plaster or putty as a final finish on the slopes. It is not always possible to sink fasteners into the slope surface, especially when it comes to concrete walls.

Before starting work, you need to acquire the following tools:

• Impact drill or hammer drill.
• Electric jigsaw or hacksaw.
• Hex key for adjusting fittings.
• anchor plates.
• Measuring devices (level, tape measure).
• Fastening materials (screws, self-tapping screws).
• Silicone sealant.

• It is forbidden to fix windows with mounting glue, foam, etc. Only self-tapping screws may be used as fastening material.

• Drilling must be carried out very carefully, avoiding contact between the drill chuck and the plastic frame. To avoid damage, it is recommended to use a long drill and a special plastic pad.

• It is desirable to use the activation of the percussion mechanism only on concrete walls.

• A brick wall with vertical voids is drilled at the butt interblock sections.

• It is allowed to tighten screws with a screwdriver. Particularly convenient are models that have a built-in motion limiter that allows you to control the depth of immersion of the self-tapping screw into the frame.

Installation of anchor plates

The first step is the installation of anchor plates. The optimal distance between individual fasteners on the frame is no more than 100 cm. It is recommended to equip windows of considerable height with an additional fastening unit. The distance between the end plate and the corner of the window should not exceed 25 cm, otherwise it threatens to lose the stability of the block. Before marking, the outer plane of the frame is released from the protective film. To install the gear elements of the plate, there are special protrusions in the profile.

To make the fastener more reliable, it is reinforced with a window screw. Further, in the same way, the plates are installed along the entire profile, observing the above recommendations for the distance between the individual elements. When bending the plate in places with a notch, it is necessary to ensure that the first bend is adjacent to the frame, and the second is above the wall attachment point.

Frame installation

The installation of the window frame must be accompanied by compliance with all proportions and distances. The distance from the frame to the opening is in the range from 20 to 35 mm. Narrow openings have to be made out with additional seats for fasteners.

Having prepared the opening, a frame is inserted into it. Correction of its vertical position is carried out by driving under horizontal sections of wooden or polymer linings up to 30 mm thick.

Having exposed the structure, you can fix it to the opening. On brick and concrete walls, 6x40 mm dowels are usually used, on wooden ones - 42x45 mm. To avoid distortions, it is recommended to follow the sequence when attaching. It is best to fix the bottom corners first, which will allow the frame to be level. Top fastening is carried out at the final stage. It is recommended to fix each anchor plate with two bolts.

Foam laying

After completing the main installation work, you need to fill the gaps between the frame and the walls of the opening with mounting foam. It is better to fill volumetric cracks in two passes, with a pause of 1.5-2 hours. On sale are several types of mounting foam with different characteristics. When choosing a suitable option, they are guided mainly by the weather features of the region. Most often, there are instructions on the packaging about this.

It is best to insulate the inside of the mounting joint with polyurethane foam, building sealant or butyl-based vapor barrier insulation tape. It is recommended to lay the foam very carefully: a lack of material will not allow you to achieve good tightness of the room, and an excess amount threatens to deform the window profile. After solidification, the foam that protrudes beyond the cracks is cut off with a sharp knife. It is better to do this after 48-36 hours.

Installation of a window sill and a low tide

According to the rules, the window sill is allowed to be mounted 24 hours after the foaming of the cracks: this gives the material time to dry well and grab. In practice, this recommendation is often ignored (especially if the installation team is working). When choosing a suitable window sill, you need to consider only those options whose width exceeds the thickness of the outer wall. The plastic product is easily cut to length with an electric jigsaw or hacksaw.

Having adjusted the window sill, it is leveled and fixed. The void that forms under the bottom must be filled with foam by placing several loads on the surface (cans of water, bricks). In this position, the product is left until the next day.

In parallel with the window sill, the tide is being installed. It is inserted into a niche under the main frame and screwed onto the window sill. As a result of this, additional protection against the ingress of external moisture into the room is created.

Exterior finish

Having installed the plastic window on the anchor plates, it is necessary to arrange the outer slope. At the same time, both decorative and practical goals are pursued, because. uncovered foam tends to gradually break down under the influence of atmospheric influences. The easiest option is to use plaster or starting putty for this. When applying the mortar, it is important to achieve complete coverage of the assembly joints. As for the interior decoration of the slope, it is usually carried out along with the general repair of the premises.

Conclusion

When choosing the option of fixing a plastic window, it is recommended to stop at the anchor plates. This is especially true in cases where installation work is carried out by beginners. In the course of work, it is important not to rush, exactly following the recommendations above.

PVC windows have proven themselves from the best side for a long time. They are multifunctional, reliable and durable. However, these indicators directly depend on how well the installation of the window system was carried out. There are only two ways: mounting windows on plates and unpacking method. With the first method, you do not need to remove the glazing bead and remove the double-glazed window from the frame. The window structure is fastened with anchor plates, which allows you to install the window without any special skills.

Methods for mounting a window structure

Both methods have their own nuances, positive and negative qualities.

Unpacking or fastening through the frame with self-tapping screws

This fastening method is characterized by the fact that the frame must be completely disassembled before installation: the blind and opening doors are removed, and only then the installation is carried out through the profile with self-tapping screws.

The unpacking method is mainly used when installing large-sized windows.

After installing the profile, the system will have to be assembled and adjusted again. This option is used for large windows with an area of ​​​​4 square meters for the reliability of fixing such an overall structure.

Leveling plates are installed between the double-glazed window and the profile

Here it would be appropriate to mention the straightening plates, which are installed in order to avoid contact between the edge of the double-glazed window and the window profile. Their presence will ensure uniform distribution of the weight of the double-glazed window and ventilation of the rebate space. The plates are made of plastic, the width of the element corresponds to the width of the double-glazed window.

Mounting with plates

When installing PVC windows on plates, there is no need to remove the double-glazed window

Installation of windows on plates begins with the acquisition of these same plates. There are models for universal use and made for use with a specific profile system. They are usually supplied with designs of complex shapes. Their peculiarity lies in the fact that they have special "lugs" and can be inserted into existing grooves on the surface of the frame.

Anchor plates with lugs are used with complex window structures

Plates without ears are fastened with bolts, and with ears - with self-tapping screws.. Requirements for bolts: 4.5 * 25 and the presence of a drill for metal.

Installation rules

A standard window requires at least five plates. In the central part of the frame, one plate is fixed, and on both sides - two each: one from above and one from below. At the same time, 20 cm should be retreated from the border of the frame.

5 plates are enough to mount a standard-shaped window

Installing windows without unpacking involves fixing the frame with anchor plates on the outside of the window opening. In this case, there is no need to remove the glazing bead and double-glazed window. When unpacking, fasteners are provided through the frame with a preliminary analysis of the window system into its constituent elements: sashes, double-glazed windows.

Fastening with plates is appropriate to use on windows of medium and small size, more often these are standard windows of houses and apartments. Large window systems (more than 4 square meters) are mounted on anchor dowels through the frame, since the weight of such a structure is significant and the plates will not withstand it.

Large window systems are installed using anchor dowels

With the help of anchor dowels, door frames are also fixed. In professional circles, among the masters of installing metal-plastic structures, this method of installation is considered the most reliable, but it has some disadvantages:

• this type of installation is difficult even for professionals. There is a high risk of damage to the double-glazed window when removed from the frame;
• this type of fixation by one person is often not possible;
• this is a labor-intensive method that takes considerable time and requires the availability of appropriate skills.

When installing windows on dowels, there is a high risk of glass damage

If there is a desire to install the window yourself using this method, then you will need to buy dowels 10 * 132 mm. Of the tools, you will need a powerful puncher - this device is professional and expensive equipment that is rarely used on the farm, so it is not advisable to purchase it for the sake of installing one or two windows. You can look for a company that rents out construction equipment, usually hammer drills are the most popular product.

With the installation of a window on the plates, all these problems will not have to be solved. You just have to buy the plates themselves.

Bolt Mounting Difficulties

A few more reasons why you should not get involved with bolting during self-installation, but you should prefer plates. In order to fix the anchor bolt, it will be necessary to drill a hole in the PVC window frame. As a result, depressurization of the double-glazed unit chamber is possible.

As a result of the fact that when drilling, the reinforcement of the system is possible, problems are observed in the future when the window system freezes through.. As a result, there is excessive moisture formation indoors and the appearance of mold on the surface of the slopes.

When fixing a PVC window on the bolts, depressurization of the double-glazed window may occur

With a lack of experience, not knowing the properties of the material from which the structure is made, it may turn out that it will stretch if improperly installed. Correcting the geometry of the window frame will be almost impossible.

There are still positive qualities in attaching plastic windows to anchor bolts:

• reliability of fastening of the structure - in order to dismantle it, it will be necessary to perform the reverse order of work that was during installation;
• after fixing the window system, there is no need to perform additional work, as is the case with fixing with mounting foam: time for solidification, leveling, cutting, finishing;
• the structure can be fully exploited immediately after it is installed;
• a similar connection method is reliable and durable, and fastening materials in the form of bolts are commercially available and have an affordable price.

Features of fastening to anchor plates

This method of fastening the window system is as simple as possible and accessible to everyone.

Compared to the unpacking method, the method is considered absolutely safe for the window system, but the only negative is that some fastening-plate elements will remain visible after installation. However, they can also be properly disguised, hidden under the slopes during their fine finishing.

Inserting a plastic window with plates is easier and safer than bolting

There is one more recommendation from experts: if the window has an opening sash, which will be used very often, then the window may fail. This fastening is recommended for moderate opening or fixed windows.

An alternative is the combined method of fastening: the upper part of the structure is mounted on plates, and the lower part is fixed with anchor bolts.

Rules for attaching a window to plates

Self-tapping screws should be used as a fixing element. Glue or foam is not suitable. The use of a percussion mechanism to create holes is only possible for concrete surfaces.

To avoid damaging the window frame with a drill, it must be of sufficient length. Additionally, you can protect the surface of the frame by placing a piece of PVC near the hole to be drilled..

Self-tapping screws are used as a fastener

When installing a window in a brick opening with vertical voids, holes for fasteners are formed in the interblock joints. To control the immersion of the self-tapping screw into the body of the frame, it is necessary to use a screwdriver with the appropriate function, which limits the torque.

The process of attaching the window to the plates

First of all, anchor plates are fastened in increments of no more than 1 meter. In order for the frame to maintain a stable position, the fastening elements must be located at a distance of no more than 25 cm relative to the corners of the frame.

The distance from the plates to the corners must be at least 25 cm

It is important to remember that the distance from the border of the window structure to the opening must be at least 2 cm.. In the case when this condition is not met, it is necessary to make recesses in the surface of the opening to accommodate the fasteners. To do this, the plates are installed on the frame, then it is installed in the opening.

On the surface of the wall with a pencil or chalk, mark the future location of the fasteners. Then the frame is taken out and a recess is made at the place of the marks with a chisel, into which the plate should enter and fix tightly. This will subsequently effectively mask the plates when finishing the slopes.

At the next stage, a window structure is placed in the opening and its position is leveled using wooden bars prepared in advance. Their thickness should not exceed 3 cm and their installation takes place only horizontally, while vertical alignment occurs, which is controlled by a level.

Vertical alignment is carried out according to the level

When the position of the frame is leveled, you can proceed to fixing the plates with dowels 6 * 40 with a concrete base or with self-tapping screws in other cases.

Gaps are filled with foam

To avoid distortion of the frame, the plates are fixed in order. First, fix the lower left corner, then the right, exercising control with a level. The top plates are fixed last. At the final stage, the seams are sealed with mounting foam.

How to fix a window: an overview of fasteners and a photo report on the installation

Hello. In this article, I will talk about how to fix plastic windows in a residential building with your own hands using an available tool. I hope that this topic will be of interest to you, as installation skills can save money.

Despite the fact that for many manufacturers the price of windows includes the cost of installation, there are many companies where they will sell you a double-glazed window cheaper due to self-assembly. Saving money is obvious!

Basic information about window installation

Installation of glazing in the opening differs depending on the type of profile used and depending on the type of walls. For example, installation in a stone, concrete or brick wall is carried out directly without any structures that compensate for the mechanical loads on the window.

At the same time, installation in a wooden house is carried out with the obligatory device of a casing box, which compensates for loads due to shrinkage processes.

There are two main requirements for the installation of plastic double-glazed windows:

• Strength and reliability of the installed glazing;
• Correct location in terms of level relative to the vertical and horizontal plane;
• Properly executed sealing of gaps along the perimeter of the opening to ensure optimal energy efficiency of the glazing.

Fasteners for installation of double-glazed windows in PVC profile

Commonly used fasteners for plastic windows: a - frame dowel with a metal seal; b - frame dowel with plastic seal; c - universal plastic dowel; g - screw (self-tapping screw); e - anchor plate

Before proceeding to the description of the installation, I propose to find out what fasteners for PVC windows can be purchased at hardware stores. There are many fasteners and such a variety is not accidental, since each variety is intended for one or another type of wall.

Window fasteners, according to the type of walls, are divided into the following categories:

• for concrete walls;
• for the installation of brick walls;
• for installation in aerated concrete walls;
• for fastening to wood.

By the way, with the use of the listed fasteners, a protective grille can be installed.

Fasteners for installation in concrete openings

Plastic double-glazed windows are installed in concrete openings by means of anchors or, as they are also called, frame dowels.

For reliable fixation of a heavy window in a concrete opening, it is customary to use anchors with a diameter of 8 or 10 mm and a length of 72 to 202 mm. The length and diameter of the hardware are selected taking into account the density of the wall - the more porous the concrete, the longer and thicker the anchor.

No matter how long and thick the anchors are, the strength of the finished result will depend on how carefully the hole is drilled. If the walls of the hole are broken as a result of unprofessional drilling, even the most reliable fasteners will not provide the necessary mounting strength.

Installation with anchors is carried out in two ways:

1. A hole is drilled in the profile and the anchor enters the concrete directly through the profile;
2. An anchor plate is attached to the profile and through the plate the window structure is fastened to the opening.

The first method is relevant if the technological gap between the profile and the gap is small. If the distance between the profile and the opening is more than 1 cm, an anchor plate can be used, since the fasteners can be covered during finishing if plastic slopes are used.

Anchor plates are metal strips of a simple or complex configuration. Plain plates are ordinary perforated strips. Along with such devices, there are “crabs” - plates that cut into the profile, which simplifies the finishing of slopes.

Fasteners for installation in brick walls

The fastening of plastic windows in a brick opening is carried out in approximately the same way as in. But there is one problem: if for installation in concrete, holes for the anchor in the profile can be drilled in advance, then in the case of brick walls, the holes are drilled in place, since you need to get into the center of the brick, and not into the masonry seam.

For installation in brick, the same frame dowel is used as for concrete walls, but with a length of at least 10 cm. A length of 10 cm is the minimum entry into the brick at which you can be sure that the fastening will not loosen or weaken when operation.

If you are sure that the brick is not hollow, and today this is rarely used, you can use dowels 6-8 cm long.

Fasteners for installation in wooden openings

The best option for installing windows in a wooden opening without a casing is self-tapping screws in combination with anchor plates. This type of fastening is equally good for log, lumber and frame buildings.

If a casing box is installed in the opening, installation can be done with screws directly through the profile. To install glazing in a wooden opening, I recommend using self-tapping screws with a length of at least 10 cm and a diameter of 8 mm. We screw in the screws in increments of 30 cm.

Fasteners for installation in aerated concrete openings

Aerated concrete blocks are characterized by low density, and therefore we choose special dowels for installation and perform installation with a small pitch between the screws.

The installation of glazing in aerated concrete walls requires detailed consideration, as more and more houses are being built using such blocks. That is why, in order to get acquainted with the installation technology, I offer a small photo report on the installation work done.

Installation of a plastic window in the walls of aerated concrete blocks

To perform installation work you will need:

• Perforated anchor plates (160×40 mm and 2 mm thick);
• Plastic dowels (50×10 mm) for mounting in aerated concrete;
• Universal metal self-tapping screws (60×6 mm);
• Electric drill and drills in accordance with the diameter of the dowel;
• Screwdriver with a set of bits;
• water level;
• Roulette and pencil.

Installation instructions are as follows:

• If the perforation in the anchor plates does not match the diameter of the dowels, we drill holes, if the diameter initially matches, skip this step and proceed to the next one;

• Along the perimeter of the profile, we fasten the anchor plates to the self-tapping screws so that the holes drilled for the dowels are located outside;

In order for the frame to be securely fixed in the opening, we mount the anchor plates on 2 self-tapping screws, which will prevent them from turning. In addition, the installation step should not exceed 30-40 cm.

• We install the frame in the opening on plastic inserts and position it according to the level in the horizontal and vertical plane;

• After the structure is aligned in the opening, we drill holes in the aerated concrete blocks in accordance with the perforation in the anchor plates;

For drilling aerated concrete blocks, it is not necessary to use a drill with a winning surfacing. Since aerated concrete is soft, it is quite possible to use the same drill that was previously used to drill out anchor plates. By the way, when drilling, we try not to pull the drill from side to side, since breaking a hole in aerated concrete is easier than ever, and as a result, the dowel will not stick to the wall.

• We screw dowels into the drilled holes;

• We screw self-tapping screws into the screwed dowels;

At the end of the installation work, we do not remove the liners from under the window, as they will provide additional stability to the structure.

• From the spray gun, we abundantly moisten the technological gap between the opening and the profile;
• We fill the technological gap around the entire perimeter with mounting foam, so that the excess applied foam comes out from the outside and the gap is completely filled;
• After the foam has dried, the excess is cut off with a mounting knife on both sides of the profile.

By the way, how to attach a thermometer on the window and at the same time not make holes in the profile in vain?

It turns out that there is nothing complicated, just buy a special thermometer with Velcro on the glass. Thermometers with ears and mounting holes should not be mounted on plastic, but on wooden frames. But, if there is a thermometer with holes for screws, fix this device on the profile with short self-tapping screws - this will not harm the profile.

In conclusion, I note that if you don’t know how to fix the handle on the profile, you can also use small self-tapping screws that will go through the PVC and will be held in the metal.

Conclusion

Now you know how to install a PVC window block in an opening of walls of different composition. I hope that the suggested instructions were useful to you. If you have any questions, as usual, ask them in the comments to the text. Also, don't forget to watch the video in this article.

Specialization: a professional in the field of construction and repair (a full cycle of finishing work, both internal and external, from sewerage to electrics and finishing work), installation of window structures. Hobbies: see column "SPECIALIZATION AND SKILLS"

PVC window anchor plates are used as an alternative to standard anchors. This type of fastener is quite practical and easy to use, but at the same time it has its own characteristics that must be taken into account.

Below I will explain what a typical plate is, as well as an example of correct mounting using such elements.

Mounting plate features

Design and varieties

Window structures made of wood, aluminum or a metal-plastic profile can be installed in two ways - with or without unpacking (that is, with the removal of a double-glazed window).

For an inexperienced specialist, removing a double-glazed window without damaging it, and then installing it back correctly is not a trivial task, therefore, when doing the installation yourself, it is best to do without unpacking.

Yes, it's harder, but it's easier to find a physically strong assistant than a specialist in dismantling glazing beads.

In order not to damage the frame and not waste time on curing the double-glazed window, not anchors, but special plates should be used to install the structure. Such a plate has a fairly simple design:

1. Material- Cink Steel. High-quality products are covered with a multi-layer anti-corrosion coating, due to which they practically do not rust.
2. Dimensions- approximately 150 mm long (there are also longer ones, for installation in deep openings) and 25 mm wide.

1. metal thickness- from 1 to 2.5 mm. Standard products are made of 1.5 mm steel, and this is quite enough to securely fix typical windows in the opening. Mounting plates from 2 mm are used when fixing heavy structures from a multi-chamber profile, large-sized frames and for high-altitude installation.

Thickened modifications have two drawbacks - the high price and the complexity of bending. If 1.5 mm bends perfectly with your fingers, then 2.5 mm will have to be bent with a hammer on a template, which will also damage the galvanization.

Plates for fastening window structures are of two types:

1. Universal. They are just perforated strips of metal. They are used for wooden windows, and for PVC products, and for other purposes.
2. Specialized. They are usually equipped with latches, the configuration of which corresponds to the configuration of the protrusions on the PVC profile. At the same time, they are fixed not only through the use of fasteners, but also due to the hook on the profile.

The second variety is more reliable, so if possible, try to use it.

Terms of Use

The fixing plate for PVC window blocks provides less fixation rigidity compared to the anchor. On deaf structures, this is not so noticeable, but in windows with large and heavy sashes, the difference will be quite obvious. To compensate for it, you must strictly follow the rules for using plate fasteners:

1. Fixation of plates on the profile. The part must not only be snapped onto the frame, but also additionally secured with a self-tapping screw with a diameter of at least 4 mm and a length of 25 mm or more (with a drill). The self-tapping screw is twisted so that the drill enters the reinforcing profile.

When installed on a wooden frame, each element is attached to the array with at least two self-tapping screws.

1. Correct placement. On the sides, the plates are installed from above and below, at a distance of about 200 mm from the corners. In the upper part, fasteners should be placed either strictly in the center or opposite the impost. The optimal step for installing the plates is 500–700 mm.
2. Bending angle. To ensure contact with the opening, the plate is not bent at a straight line, but at an acute angle. Due to this, the transverse displacement of the frame is minimized, and the rigidity of the fixation is increased.

1. Fastening to the opening. Fixation of each plate in the opening is carried out using one or two plastic dowels with a diameter of 6–8 mm. The dowel is driven into a pre-drilled hole, and its wide neck should press the metal part against the plane of the opening. Final fastening is done with a locking screw with a conical point.

For installation according to all the rules for each attachment point, it is necessary to choose a bed with a depth of about 2 mm with a chisel so that the plate is flush with the opening plane. So, of course, no one does: all the same, the fasteners will be hidden by plaster or slope sheathing.

Plate mounting technology

The instruction for the installation of window structures involves working according to the following scheme:

Illustration	Stage of work
	Design preparation. We unpack the frame, remove the sashes from the hinges, install the connecting and expansion profiles. We glue mounting tapes on the frame: vapor barrier on the inside, vapor-permeable on the outside.
	Plate installation. In the selected places, we install the plates, snapping their fasteners into the grooves of the profile. We bend the plates at an angle so that when the frame is installed in the opening, they are pressed against the slopes.
	Plate fixation. We fix each plate with a self-tapping screw with a drill. Screwing it through a plastic profile into a metal armour.
	Drilling for fasteners. We install the frame in the opening and align it in three planes using mounting wedges. We correct the position of the mounting plates, pressing them tightly to the edges of the opening. We drill sockets for fasteners through the holes with a drill. The depth of the nest must be at least 10 mm greater than the length of the dowel used.
	Structure fixation. We hammer plastic dowels into the holes, pressing the plate to the base. We fix each dowel with a locking screw.

Working according to this scheme, we get the opportunity to quickly fix the frame without violating its integrity and without removing the double-glazed window. The fastener itself will subsequently be masked by the finishing of window slopes.

Conclusion

The anchor plate for plastic windows is a fairly versatile mount. But in order for the installation to ensure reliable fixation of the structure in the opening, it must be carried out in accordance with all the rules. The tips and videos in this article will help you learn these rules, as well as advice that you can get by asking a question in the comments.

Coziness and a comfortable microclimate at home are created primarily not by interior items, furniture and textiles, but by well-installed windows. Proper installation eliminates the occurrence of drafts, the accumulation of moisture and the appearance of fungus on the slopes and walls.

The choice of fasteners is based on the material of the walls and the design of the window opening. These can be construction screws, anchor bolts, expansion metal or plastic dowels, anchor plates.

Anchor plate options

Anchor plates are used to install both metal-plastic windows and wooden double-glazed windows. Any window installation technology pursues the main goal - the redirection of all force effects (wind, window weight, building load) from the plane of the double-glazed window to the wall.

The plate is a metal bar 25-30 mm wide with guide notches along which it is bent during installation. The bar has several holes for fastening with anchors (screws, self-tapping screws) in the desired position. Plates are stamped from sheet steel with a thickness of 1.2 mm, 1.5 mm, 2 mm in various modifications and treated with an anti-corrosion zinc coating. For each profile, it is important to choose the size of the anchor plate.

Features of the use of plates and their types

Mounting on an anchor plate has no alternative when installing a window profile in an opening with a “loose” wall component - these are three-layer walls, adobe blocks, wooden beams, hollow bricks.

Anchor plates are of two types:

• rotary;
• fixed.

Plates with a swivel assembly are used if fastening in the opening itself is not possible. Mounting on a rotary anchor is used for arched, trapezoidal and polygonal windows.

The usual fixed anchor is designed to fix the window in the opening, but the angle of attachment can also vary.

Anchor plate advantages

The ability to quickly create a strong and, at the same time, elastic window-to-wall connection with the help of a plate is the main advantage of this type of fastening. Seasonal and daily temperature deformations of the window do not affect the stability of the installation of the anchor plate.

Other advantages of anchoring a window onto a plate:

• There is no need to disassemble the profile and drill through it;
• choice of attachment point;
• ease of leveling the window according to a plumb line or level;
• lack of large mounting holes;
• exclusion of ingress of natural moisture inside the profile and seam;
• when dismantling the window, the plates are easily unscrewed, unlike anchor bolts;
• the window can be reinstalled;
• low cost of fastening;
• window installation time is halved compared to installation on bolts.

The advantages of installing windows on anchor plates are so noticeable that they are used everywhere when working with any wall materials.

The only case where this type of installation may not be acceptable is the installation of very heavy balcony sections to the full height of the wall, or the placement of several rows of windows directly on top of each other. In this case, the planned load on the fasteners may be too high and the anchor plates should be noticed on the anchor bolts.

Installation of PVC windows on anchor plates

Installation of PVC windows or balcony blocks begins with the calculation of the operating load. The type of opening-closing windows affects the support force, the total traction effect on the hinge mechanism and determines the required number of plates for installation. Having prepared all consumables, proceed to the installation:

1. Remove the transport film from the outside of the window frame;
2. Install the toothed "legs" of the anchor plate into the special protruding parts on the profile. Use a self-tapping window screw as an additional fastener.
3. Screw the plates along the perimeter of the entire profile, keeping distances from the frame corners of 150-200 mm. The further spacing of the plates is 500-700 mm.
4. Bend the plates at the notches in such a way that the first fold is at the junction with the frame, and the second at the attachment to the window opening.
5. Place the frame on hard pads. They should be not only in the corners, but also under each section of the window. Secure the frame vertically with wedges.
6. Using a level, fine-tune the frame in all planes and firmly fix the plates in the opening with two anchors.
7. Moisten the installation seam with water using a spray bottle.
8. Insulate the mounting joint internally with polyurethane foam. Consider its expansion properties so that it does not come out on the profile itself. The following materials are also suitable for internal insulation: building sealant (mastic), vapor barrier sealing tapes based on butyl material.
9. Creation of an external insulating layer: finishing slopes with plaster or lining with dense protective materials (stone tiles, facade bricks).
