House with flat. Projects of houses with a flat roof (62 photos): new materials - new opportunities

House projects with flat roof allow to build country houses using modern technologies. Their development led to the use various materials for roof installation. Before arranging it, you should familiarize yourself with all the stages of designing such exclusive buildings.

Projects of houses with a flat roof allow you to build country houses using modern technologies

When designing a house with a flat roof, it is important to identify all its main advantages. Among the positive aspects of the construction of a modern building are:

unique creative design, for example, a high-tech house with a flat roof or others;
savings on heating the building inside;
availability of additional square meters.

Arranging country house or a cottage with a flat roof, you should pay attention to design trends Western countries. Minimalism or hi-tech style: here you can always feel the material benefit. A house with a usable roof will be very comfortable. At the same time, this roof design allows you to improve a house with a flat roof by arranging a special area for sports games.

The expenses incurred in the process of designing houses or cottages with a flat roof are not a very expensive option. If a layer of snow remains on a flat roof in winter, it will act as a good insulator. Heating such a house will cost less.

Although it is acceptable for many to implement flat roof house designs, these options do have their drawbacks. A flat roof should be installed taking into account the requirements for laying waterproofing. Among the main reasons why home owners can criticize such a structure with any design is its leakage. This is usually due to minor deviations in technology or negligence of builders. Water may accumulate on the roof surface.

To completely eliminate the leak, reconstruction must be carried out, which can be very expensive. Roof cleaning is usually done independently without the use of equipment. Indeed, as the snow begins to melt, the waterproofing layer of the structure will begin to be subjected to heavy loads. As a result, the surface will be destroyed.

How to install a flat roof

Developing projects one-story houses with a flat roof, it is important to consider the following key points:

the roof should not be completely flat, so you should take into account its angle of inclination equal to 5-15°, otherwise this type of structure will be built only to collect rainfall;
An ideally flat roof should be sloped, since the required slope is required for drainage.

A terrace or gazebo with a flat roof is equipped using bulk building materials. You will also need concrete bracing or polymers having a fixed angle. This sheet material is called polystyrene boards.

A roof square, requiring an even roof angle, requires the presence of a load-bearing plane. The de-sloping stage must be included in the implementation plan for the house project. There are 2 types of projects country houses with a flat roof, which depends on the features of the roof structure:

lightweight;
exploited.

Each of these types has its own characteristics that should be taken into account during the roof construction process.

When arranging a country house or cottage with a flat roof, you should pay attention to the design trends in Western countries

Lightweight flat roofing

The lightweight version is a flat roof that does not require operation. It can be made in any style, for example, high-tech. This structure should be erected in stages:

laying of the main beams (timber material) is carried out on load-bearing walls or on a mauerlat mounted on them;
fixation of beams laid in increments of 0.5-1.0 m is carried out to the base using anchor pins;
solid material is laid on the beams wooden sheathing, consisting of edged boards inch thickness;
A membrane is laid on the sheathing for waterproofing.

The main beams can be wooden beams with a cross-section of 100x100 or 150x200 mm, which is determined by the calculated weight of the roof. The lathing is installed without any holes. The installation of the waterproofing layer must be multi-layered. All joints are glued using glue or tape.

Creating a flat roof “pie”

Experts do not recommend saving cash when purchasing and installing a waterproofing membrane. This material cannot be replaced with roofing felt, which will not provide the required effect, and the house cannot be left without a roof. When arranging thermal insulation for a roof, extruded polystyrene foam boards or mineral wool are often used. The heat insulator must be mounted on the waterproofing layer carefully so that cracks do not form. Even with the slightest inaccuracy thermal insulation material may eventually begin to let in cold air.

When laying insulation on a timber sheathing, vents for ventilation are immediately installed, which will prevent the accumulation of condensation. This will keep the insulation dry. Good insulation is expanded clay, which is popular when creating projects of one-story houses with a flat roof. This layer should be about 100 mm. At the final stage of roof installation, it is necessary to provide waterproofing protection to the structure. The modern building materials market offers a membrane. A lightweight flat roof is not able to withstand heavy loads, so it cannot be used in such conditions.

Flat solid roof

A private house with a flat, solid roof should not sag, so you can take advantage of all the free space. In this case, no cracks should appear on the roof of the house. To create a flat roof, you will need to master special technologies. This requires some effort. There are several ways to install a solid roof:

Using concrete slabs as floors, taking into account that the supporting structures are strong enough to withstand the load.
With the use of metal support beams, which make it possible to make a roof covering, T-bars or I-beams, as well as channel No. 14-16.
Using ceramic blocks placed on support beams to create a hard surface.

The first method requires the use of heavy equipment. This type of roof must be insulated, which is done from inside the room. A plank flooring consisting of boards with a minimum thickness of 22 mm is laid on metal support beams. Then a layer of expanded clay with a thickness of at least 150 mm is poured. At the last stage of arranging the hard surface, you can proceed to laying the concrete screed.

Method 3 is most in demand in modern construction. Ceramic materials are used for installing solid roofs. roofing materials. They can be immediately laid on support beams, which should ensure the strength of the roof. This material is able to retain heat well. It has excellent soundproofing characteristics.

Ceramic roofing blocks have the main advantage, that is, moisture resistance. The screed is poured without first filling in the expanded clay. A significant drawback of the material is its high cost. Additionally, a roofing membrane is installed on a flat-type solid roof, which improves operational properties material and strengthen the waterproofing layer.

When choosing a project, it is important to remember that a flat roof is quite sensitive to the waterproofing layer. The pitched roof hides various operational defects. Having decided on the project for building a house with a flat roof, you should develop a further action plan, purchase quality materials. It is necessary to discuss in detail all conditions and requirements with the builders. As a result, a non-standard building will be erected, for example, in high-tech style, meeting European standards.

Projects of houses with a flat roof

If the search for a cottage project is unsuccessful, then you can design it with the help of a team of specialists. This exciting process allows you to see each design stage, starting from the overall concept. This process ends with the creation of a complete image, thought out to the smallest detail. Here it is necessary to take into account not only your own wishes, but also the landscape features of the suburban area.

Any project catalog provides the use of various architectural techniques. This entails the use of certain methods or technologies. The development of projects that allow the construction of two-story or one-story houses with a flat roof requires taking into account several points:

Conditions of the climatic zone where the object is located, which should affect the size of the thickness of the heat insulator used or its absence.
The roof being installed may or may not have a drain, which determines the method of water drainage used.
The functional purpose of the terrace with a roof is determined, which can be a resting place for people, a parking lot for a car, small garden for planting crops.

The nature of the use of the building influences the choice of type roofing structure, which could be:

traditional: the waterproofing layer is located above the thermal insulation;
inverse: the layers are arranged in reverse order.

If the process of roof operation involves the use of hydro- and thermal insulators, then they must bear the load. It can come from people or vehicles.

The roof of a house with an exploitable flat roof can be made of PVC membranes. She has long term service and does not require special care. Heating elements are used to remove snow from its surface.

Direct way to select projects two-story houses or one-story buildings - a specialized site. They are lightweight and convenient to build, especially if the material used is gas silicate (aerated concrete) or a large-format sample, which is classified as warm ceramics. When choosing a house project, you should take into account the needs, the number of rooms for a specific purpose, the presence of a garage, etc.

Attention, TODAY only!

“was perceived extremely negatively - the legacy of Soviet construction had an impact, when, due to violations of technology, poor quality of materials and poor quality of work, flat roofs of high-rise buildings began to leak within a couple of years.

Therefore, in private housing construction, preference was given to pitched or hipped roofs. The situation changed with the advent modern technologies and roofing materials, which made it possible to ensure durable and reliable waterproofing roofs of a house with a flat roof.

Flat roofs: advantages and disadvantages

The main reason for the growing popularity of flat roofing was the popularity of modern design trends - project high-tech houses with a flat roof allows you to match the exterior and interior of the building with the style features. Flat roofing is also often used in modernism and minimalism.

However, except impressive looking and visual appeal, it has a number of other advantages:

speed of roof construction - arrangement flat roof takes less time than a pitched (hipped) roof, including due to the convenience of working on a horizontal surface

accessibility of maintenance - there is no need to install ladders or involve steeplejacks, all work (cleaning gutters, monitoring ventilation ducts, removing leaves, etc.) can be done independently

obtaining additional space by arranging a usable roof

flat roof is ideal for installation and further operation/maintenance of various technological equipment – solar panels, wind generators, heaters, air conditioners, antennas, water collection systems.

A rather controversial issue is the cost of installing a flat roof. On the one hand, the area of such a roof is much smaller than that of a pitched roof, which means that less roofing materials will be required. And the roofing materials themselves used to construct a flat roof are cheaper.

But, on the other hand, the use reinforced concrete floors(in most cases, especially when creating an exploitable roof) creates a significant load, requiring reinforcement of the foundation and load-bearing walls, especially if these are projects two-story houses with a flat roof. Which, while saving money on roof installation, leads to an overall increase in construction costs.

The issue of snow accumulating on a flat roof during the winter also remains ambiguous. Some experts tend to consider this a positive point - snow acts as an additional layer of heat insulation, thereby reducing heat loss. Others argue that snow increases the load on the load-bearing elements (and, therefore, this should be provided for in the design), and its subsequent melting can provoke a violation of the tightness and leakage of the roof.

Types of flat roof

Projects of houses and cottages with a flat roof can have various types roofs:

operated - involves regular presence of people on the roof or the installation of heavy objects. Such a roof requires a rigid base (most often reinforced concrete), and the thermal insulation material must withstand serious static and dynamic loads and be strong in compression

unused - does not provide for a large load, so the rigid (concrete) base can be replaced wooden joists with lathing. To service such roofs, special ladders or bridges are used to reduce the pressure and distribute it evenly over the entire roof area

inversion - the insulation layer is located above the waterproofing layer, thereby providing it with additional protection from temperature changes, ultraviolet radiation and mechanical influences, the number of freeze/thaw cycles increases. Together, this leads to a significant increase in the service life of the roof. Most often, inversion roofs are used as functional roofs - you can put furniture on such a roof, walk on it, or break it flower beds.

Operable roof: every square centimeter is in use

The ever-increasing cost of modern housing forces us to make the most efficient use of all available space, and house designs with a flat usable roof will help with this. In fact, if we consider projects of one-story houses with a flat roof, the owners have at their disposal an additional “seasonal” floor, which makes it possible, for example, to refuse verandas, thereby freeing up additional space on the site.

Projects of houses with a flat roof

In our country, a flat roof is a rather atypical solution. Therefore, such a house will stand out among other buildings. A flat roof serves in its own way as an indicator of the status of the owner, the breadth of his views and the absence of conventions.

But a house with a flat roof is not just a tribute to fashion and a desire to stand out. If previously only elite apartment buildings, then today it is increasingly becoming an attribute of country houses. The flat roof allows you to realize the fantasies that owners pitched roofs and never dreamed of it. This is a luxurious flower garden and a pond with a beach area. Material benefits also play an important role when choosing such a roof. After all, it eliminates the need to design and build a rafter system. True, a flat roof also has significant disadvantages. For example, the lack of under-roof space, and therefore the lack of thermal insulation that it provides.

A house with a flat roof needs an attic with high-quality hydro- and thermal insulation. To do this you will need expensive materials. No matter how flat the roof is, minimum slope is still needed there. Usually it is 5-15 degrees. This angle of inclination is sufficient to prevent the roof from collecting rain and melt water. Moreover, on a perfectly flat roof you will have to make a slope, that is, give it some slope. For this purpose, special materials are used - plates with a certain angle. It is possible to use bulk materials. If you are worried about clearing snow in winter, calm down, you don’t have to pick up a shovel. A warm cable will help solve the problem, thanks to which the snow will constantly melt and flow off the roof on its own. However, even what is essentially a disadvantage can also be an advantage. It is not necessary to remove all the snow from the roof. By leaving it there in an amount safe for the roof, you get natural thermal insulation, which means you can save on heating.

If you decide to order a house project with a flat roof, you should remember that such construction may be associated with certain difficulties. For example, during the installation of a roof, all requirements for waterproofing must be met. Otherwise, you will end up with leaks and water pooling on your roof in the future. You can order individual project or buy standard project houses with a flat roof. In any case, you will be asked to choose one of two types of roofing. This can be a lightweight or exploitable flat roof. Lightweight roofing does not provide for operation. In this case, the beams are laid on top of the load-bearing walls and fixed in place. The next step is to install the sheathing, then lay the waterproofing in several layers.

The next stage is laying thermal insulation and installing ventilation vents to prevent condensation from accumulating in the insulation. Finally, you need to waterproof the roof using roofing membranes. If you choose finished project flat roof houses and would like to arrange a recreation area at the top, then you need to choose a structure with a solid roof designed for significant loads. There are several ways to arrange such a roof. Floors can serve as concrete slabs. It will not be possible to lay such a roof without the use of heavy equipment; in addition, it needs to be insulated. Also the basis roofing You can put metal support beams. Most modern way– ceramic roofing blocks. This material will give the roof strength, keep heat inside and keep out sounds from outside. Such blocks are resistant to moisture.

Buildings with a flat roof look original and are practical, especially in the cold season. All the pros and cons this option. One-story, two-story, wooden houses in high-tech style and minimalism. We'll look at everything in more detail later in the article.

Pros and cons

The main advantages of this design are the following factors:

efficiency – triangular roof the area is much larger; its construction requires more materials;
time– the construction of a flat roof requires less time, which is very valuable when building houses, especially if they are built from scratch;
safety for construction workers– it is difficult to fall from a flat surface, they will not have to provide themselves with insurance, build protective structures that require time and money;
ease of use– if you find a hole or need a routine inspection or repair, it will be easy for you to climb in for inspection;
practicality– many exploit the entire flat surface, make it into a flower greenhouse, a greenhouse, and use it for installing equipment.

Designers classify such designs as minimalism, which are still in fashion, so your living space will be in trend.

Among the disadvantages are:

impossibility of rolling snow in winter;
the creation of special gutters and their regular cleaning are required;
To prevent water from stagnating, you will have to install humidity control systems.

Those who were not afraid of the design flaws tried to install it for themselves and were not disappointed. Any building requires care and maintenance, so the need to remove water and snow is not terrible.

How to make a flat roof on a square house?

When planning the construction of a structure for a square building, you need to immediately decide what type it will be. The complexity of the work done will depend on this. Choose one of the options:

not in use;
exploited.

It is easier to make a flat roof that is not in use, if you want to reduce costs, it is better to choose this option. To do this, you will need to install beams on the walls of the frame house so that the distance between them is from 50 cm to 1 m. To fix them, use construction pins.

After fixing the beams, sheathing of boards is performed. Typically, those with a width of at least 3 cm are used. They need to be laid tightly so that holes do not form; defects at the beginning of work will make the entire structure fragile.

Install on the finished sheathing waterproofing membrane, fixing the material with either construction tape or glue. Then thermal insulation and waterproofing are formed. This short description technology that allows you to make a flat roof on a square structure.

The main difference in the construction of a roof structure that is not in use and one that is in use is that in the first, the waterproofing is located above the thermal insulation, and in the second, vice versa.

Projects

After determining what the structure will be, whether non-operational or exploitable, a plan or project is drawn up. The main goal of this stage is to calculate the loads that will be exerted on the building. On the basis obtained, you can calculate the amount of materials required.

If you do not have experience in constructing roofs, it is better not to create the project yourself. This task should fall on the shoulders of professionals who can take into account all the nuances. Many construction companies offer developed programs that allow you to select a project to suit your needs. ready house or completely new, when built from scratch.

The given diagram of how a flat roof is made is difficult to implement for a person who does not have the skills, so it is recommended to contact one of the available companies. Their work on creating the project will include:

drawing up a sketch of the entire building;
calculation load-bearing structures– experts calculate the number of beams, the distance between them, and other special structures of the sheathing;
creating a plan-scheme.

The final plan is an important part of the design. When creating it, all the nuances are taken into account, additional elements roofs. Consider the location and quality of the following parts:

junction nodes;
cornice (to protect walls from flowing water);
funnels for collecting water;
aerators – for removing water vapor;
lightning outlet;
drainage

Single storey

This option is suitable for a small family. The one-story building looks compact, there is no extra rooms, most of them relate to minimalism. A flat roof that also goes with this style would be suitable.

A triangular roof gives a one-story building volume and visually enlarges it, which often looks ridiculous. Flat - on the contrary, it emphasizes the neatness of the building. Among large quantity projects of one-story buildings, which are offered by many companies, country house options are also in demand.

If summer cottage plot small, you have to save space without cluttering it with unnecessary building elements. Many people decide to use the option with a usable roof for their dacha, placing a terrace, flowers, even a greenhouse on it. Because of small size The roof of a one-story house can be strengthened so much that furniture can easily be installed on it: tables, chairs, sofas, cabinets.

Advice

If you want to install a pool on a one-story building, you need to discuss this in advance, when you start designing. In such cases, particularly powerful reinforcement and a special waterproofing system are required.

Two-story

Such options are suitable for large families, so that everyone feels comfortable, it is important for them to have their own space. It is better to build a two-story one than a long one-story one. This saves materials, money, and costs.

As a rule, in a large family there are great needs; everyone requires their own conditions for comfort. Some people want to enjoy relaxing in the pool, some want to plant their favorite plants, and some want to have breakfast and dinner while enjoying the view of the sunset. A two-story building with a flat roof will provide the opportunity to implement any ideas.

If the weight allows, the foundation and wall structure are strong, you can organize an entire beach on the roof. To make it comfortable in the heat, canopies are made around the pool to create shade. You can also use plants for this purpose; many prefer decorative ones.

Another popular option for using a large roof of a two-story structure is arranging a sports ground. Not every sport is suitable for playing at altitude, but for most it is possible. Many people install a tennis court, but it needs a sufficient area, otherwise you will have to run far for the ball.

Roof-mounted exercise equipment is especially in demand. Treadmills, orbitreks, other fitness devices that are under open air – good opportunity play sports outdoors. However, given that they run on electricity, a cover must be installed to protect them during rain.

If you plan to use the roof for active recreation, you need to take care of safety by installing sides.

Hi-tech

The high-tech style has been relevant for several years now. Its connoisseurs prefer to adhere to the desired design not only when decorating rooms inside, but exterior finishing buildings. The main features of the style are smooth surfaces and textured finishes.

High-tech elements are not suitable for creating a cozy, homely, modest environment; if you prefer old-fashioned home design options, it is better to avoid this. Initially, the style was used only for offices and was classified as official. Decades after its invention, it began to be used for residential premises, and there were immediately many fans of such rigor and minimalism.

High-tech is focused on demonstrating existing equipment, so modern exercise equipment and other equipment on the roof will look appropriate. This is not a modest style, so it is more often used for large two-story houses. If it is used to decorate a one-story building, it should look large.

Another high-tech feature is a lot of artificial lighting. Both small decorative lanterns and large main light sources can be installed on the roof. In order to strictly follow the rules of style, lamps must have a characteristic geometric shape.

The walls and roof are usually plain, but the colors should be bright and harmoniously combined with each other. Suitable shades are beige, light gray, and metallic. Suitable for harmony with them dark colors. If they have walls, then the roof should be dark blue, gray, burgundy, emerald, and other bright colors.

This will be interesting to you:

It should not just be a living space, but also have high functionality, convenience and comfort. Frame house with a flat roof can fully meet these needs, and it is also the most quickly erected and economical project.

Advantages and disadvantages of frame houses with a flat roof

Despite the attractive cost, they have not gained much popularity in countries in the former Soviet Union. While more prudent Canadians and residents northern countries Europe has long been using such houses to build budget projects.

This arrangement is due to the fact that modern houses with a flat roof are not perceived by our people, because they are accustomed to using various non-residential areas for household needs and storing any items there. Also appearance Such houses seem quite simple, and require a lot of effort on the part of the designer to somehow fix it.

Its advantages also include durability, lightness and reliability of the design. On average, its cost, compared to brick house, are 30% cheaper, and the presence of a second floor or attic makes their cost equal. But the construction technology itself frame houses does not allow the construction of buildings with more than two floors, because the weak point of frame houses is the strength of the frame and interfloor ceiling under heavy loads.

Advantages:

Smaller roof surface and, as a consequence, reduced installation costs rafter system and roof roofing;
Low windage of the building allows their use in regions with strong winds;
A pitched roof allows you to save money during installation drainage system, and in winter time the layer of snow will not fall off and will serve as air cushion which retains heat;
Project one-story house It's always much easier with a flat roof and cheaper compared to conventional brick houses;

Flaws:

A flat roof requires enough complex system sediment removal;
In winter, to drain snow and ice, heating of the roof surface is necessary;
It is necessary to regularly monitor the condition of the roof and carry out minor repairs of cracks;

Types of flat roofs

Flat roofs do not have any uniform design features. Therefore, they are divided according to type of use and design into:

Inversion;
Regular;
Exploited;
Unexploited;

Main stages and technologies of construction of frame houses

Design

In the process of designing houses with a flat roof, the presence of a slope, that is, the difference between two opposite walls, is provided for. This is usually done by making a slope between the front and the back of the house, which is why most houses with a flat roof are rectangular in shape.

Two methods are used to arrange the roof.

The first is when the ceiling and roof form one solid partition, but in this case, to ensure the slope, the ceiling will also be directed at an angle.
In the second case, a small amount of space is added between the ceiling and the roof.

Laying the foundation

Since one-story frame houses They have relatively light weight, so you can do without a particularly powerful foundation. Regarding the roof, the main load will fall on the perimeter around the top edge of the building, and on the rafter system, if the roof has space underneath.

That's why special attention It is necessary to pay attention to the strength of the rafter system, especially if the roof has a slight slope, then the load will be greater than that of a roof with a large slope.

Construction of walls

The walls of frame houses are built quite simply. First install bottom trim, on which, like a constructor, the floor and load-bearing supports for the second floor or roof are installed. Afterwards, the internal and outer skin, and the space between them is filled with special insulation.

If a pitched roof is provided, then the space under it is also filled with insulation and a special layer of waterproofing. Frame for pitched roof consists of a wooden lattice stuffed over the rafters. This provides sufficient rigidity for subsequent installation of decorative coating.

Exterior finishing

When building frame houses, you should especially carefully select materials for decorative cladding Houses. This is due to the fact that houses with a flat roof and poor decor have a rather simple and unpresentable appearance, and are sometimes associated with outbuildings.

But this can be avoided by choosing suitable decorative materials, the range of which, today, is quite large.

Construction of a flat roof

Almost all roofing materials can be used to equip a roof; the only thing that needs to be taken into account is that they all must have the necessary characteristics and be organically combined with the design of the building.

Despite the fact that the roof looks completely level, it must still have a minimum slope to allow rain to drain away. In regions with no a large number precipitation, it is permissible to arrange a roof with minimum slope- from 5 degrees, and in regions with a large amount - from 10 degrees.

Moreover, it should be formed not only by the slope of the ceiling, but also by pouring bulk insulation materials. Even a relatively large angle of inclination will not cause additional difficulties during the process of insulation and roofing.

After all, almost all the work has to be done under your feet, and not at height and in dangerous conditions, as when roofing standard gable roofs.

Construction of a lightweight flat roof

Once the load-bearing walls have been erected and the top tie has been installed, the support beams for the roof can be laid and secured. Depending on the expected weight of the roof structure, and the maximum values of precipitation, calculations are made regarding the pitch and dimensions of the required beams. Consequently, the greater the load on the floor, the denser and thicker the beams must be placed. Typically, the pitch of the beams is 0.5-1 m, and the cross-section used is from 100×100 mm to 150×150 mm.
On a layer of load-bearing beams Lay out a layer of boards, plywood, drywall. Then a film of hydro- and vapor barrier is covered on the resulting surface, and the resulting joints are overlapped with wide tape.
Next, a thermal insulation layer made of mineral wool or polystyrene foam. Gaps and holes need to be filled polyurethane foam. If the heat insulator is capable of absorbing moisture, it is necessary to provide vents to remove it. A layer of moisture-resistant plywood is laid on top of this.
At the end, this entire “pie” is covered with a layer soft tiles or euroroofing felt.

In the end, you end up with a fairly warm and reliable roof, the surface of which can be used for your needs.

Construction of a solid flat roof

A flat hard roof has a significant weight, but in turn it can withstand quite large loads. That is why the walls of the building must have a sufficiently large margin of safety, and the ceiling should be done using metal beams, because wooden ones are unable to withstand heavy weight.

To insulate the ceiling, use a fairly large, up to half a meter, layer of expanded clay, covered with a layer of plywood and waterproofing. On top of which it is laid concrete screed with reinforcing mesh inside. Such a roof can withstand quite a lot of weight and rarely needs repairs.

Solid roofing with concrete slabs

This roof is quite quickly erected, but it is heavy and requires the use of heavy equipment. Therefore, it requires a strong foundation and strong walls.

A layer of boards is laid on top of the floor slabs, on which expanded clay is placed, and a layer of reinforced concrete is poured on top. Such an overlap is quite strong due to its solidity, but also requires additional insulation both above and below.

Insulation materials for roofing

Loose-fill insulation is considered the most accessible and cheapest, such as expanded clay or perlite sand. But in comparison with polymer or mineral insulation, they have less thermal insulation and with their help it is quite difficult to achieve a perfectly flat inclined surface.

Insulation based on mineral wool Although they have fairly high thermal insulation, they are quite soft. This fact forces us to take measures to strengthen the upper waterproofing layer.

Usually, sheets of plywood are laid on top of mineral wool and made cement screed, which distributes the load and gives additional rigidity. But cement has a lot of weight, and therefore the structure must be strong enough.

Foam glass is a new product on the insulation market. This material is distinguished by its unique qualities - it is resistant to high temperature, is not susceptible to biological corrosion, high strength, has a fairly long service life due to low expansion and contraction under temperature changes.

Extruded polystyrene foam It is also a high-quality new product on the insulation market and has unique characteristics, including: in terms of thermal insulation, it is the lowest heat-conducting substance, has high strength, is resistant to chemical and biological influences, and practically does not absorb moisture. Thanks to all these characteristics, it is the best insulation on at the moment, but as a consequence - a high price.
