Is it possible to insulate the frame of the house with foam. Insulation of a frame house with polystyrene foam: technology. The choice of insulation and tools. External finishing of a facade. How to insulate walls with foam from the inside

After the construction of the frame, it is time for insulation works. By itself, the wooden skeleton serves as an excellent basis for filling the cells. insulation material, one of which is foam. This material has excellent thermal insulation properties and other characteristic advantages, including an affordable price.

First you need to decide what types of foam will be needed to insulate the walls, floors and ceiling in the house, followed by the choice of brand of material. Then comes the time installation work, which need to be carried out, following correct methodology in compliance with all rules and regulations. As a result of all the manipulations, the building receives excellent thermal insulation and is ready for further finishing work.

Kinds

Styrofoam is not one material, but a whole class of them, hallmark which is a foamed cellular structure. At thermal insulation works in a frame house can be used the following types foam:

PPT- polystyrene foam heat-insulating plate or "ordinary polystyrene";
PSB-S- expanded polystyrene suspended pressless self-extinguishing, non-combustible appearance polystyrene;

penoplex– a modified version of expanded polystyrene;
penofol- rolled polystyrene foam with a foil backing;
liquid foam- urea-formaldehyde foam, great for blowing out cracks, joints and other problem areas.

Each of these types has its own specifics, and its use is appropriate under certain conditions. Standard foam has several basic criteria, such as density and purpose: for walls, plinth, foundation, and the like.

Density determines the main parameters of the foam - thermal conductivity, the higher the density, the better the thermal insulation properties and strength, which is in the same progressive relationship.

The main types of foam have a density of 10-35 kg / cu. m and the corresponding marking: PPT-20 (20 kg / m3), PPT-35 (35 kg / m3) and so on. And also this parameter determines the price and scope of the foam. For example, PPT-15 is relatively soft and cannot be used for floor insulation.

PPT-35 is considered universal, having the highest performance, because of which it can be used everywhere, but its price is also the highest. It is not advisable to use such foam for internal insulation walls, where its strength will not bring any dividends, since it is simply not needed there. The dependence of strength on density is much higher than for thermal insulation properties. Often PPT-15 is used for roof/ceiling insulation, PPT-25 for walls and other vertical surfaces, and PPT-35 for floors.

It is not difficult to lay a heater with your own hands, if you follow the recommendations of specialists. It can be insulated with both mineral wool and penoplex. Each of them has both its pros and cons and different reviews. How to insulate, you can choose yourself.

Gradual warming of the house

vapor barrier

Styrofoam does not allow steam to pass through, and, accordingly, does not allow moisture that has entered through the facade of the building to evaporate. To prevent its penetration to the frame of the building from the room, it is necessary to make a vapor barrier.

double-sided sealing adhesive tape;
reinforced mesh or other material as a vapor barrier.

The work is done in a certain order.

At the time of work, the frame must be treated with protective impregnations, then access to it will be closed.
Dust and dirt are removed from the frame in the work area.
The protective film is removed from the tape and applied to all frame elements with which the vapor barrier will come into contact.
The protective film is removed from the tape on the second side.

A roll with a vapor barrier is rolled across the racks, sequentially pressing against the tapes. The joints are glued with tape, and the webs of the rolls overlap each other by about 200 mm.
After gluing the film, it is additionally fixed with a stapler at intervals of 25 to 30 cm.
To provide further wall cladding and protect the vapor barrier from damage, slats are mounted on the frame. It does not matter if they will be attached immediately after the vapor barrier or immediately before finishing.

The wall vapor barrier technology provides absolute protection against the penetration of moisture into the foam, but prevents it from leaving the room. In this regard, the house should be equipped with a good exhaust ventilation otherwise mold and other problems cannot be avoided.

Thermal insulation and waterproofing of walls

After carrying out the vapor barrier, it is the turn of the walls to be insulated with foam plastic. For these purposes, you will need the following materials:

PPT or PSB-S slabs 10 cm thick, suitable foam with a density of 15 kg / cu. m or above;
film with wind and hydroprotective properties;
rails with a section of 20x30 mm;
adhesive sealing tape;
assembly foam.

The work is carried out as follows.

The slabs are laid between the racks of the frame, often the distance between them was initially laid down for the size of the slabs - 50 cm. For cutting foam, it is better to use a small hacksaw or a mounting knife.
The gaps between the frame and the slabs are filled mounting foam.
The second layer of slabs is laid so that the joints do not line up with the first row, otherwise there will be cold bridges. The cracks are also filled with foam.
The film for wind and waterproofing is mounted on the outside like a vapor barrier inside. The frame is glued sealing tape, then a protective film is attached to it and subsequently fixed with a stapler.
On top of the attached film, rails on self-tapping screws are attached to the frame. The created gap is necessary for ventilation in order to remove moisture trapped under the facade cladding. When installing the rails, you need to use a level to maintain the correct verticality of the walls. If the frame was not built perfectly, the slats make it possible to fix it. The location of the rails is easily adjusted by placing scraps of plywood under the required end.

There is no big difference between sheathing the frame from the inside first, and then from the outside, or, conversely, the sequence of these stages is left to the discretion.

Floor insulation

At this stage, you will need the following materials:

PPT-35;
vapor barrier film;
sealing adhesive tape;
mounting foam;
penofol or other substrate.

Isolation occurs according to the following plan:

a vapor barrier film with gluing of joints is laid on the logs, the overlap of the sheets should be about 200 mm;
PPT is laid between the logs, and the gaps between them are filled with foam;
a second layer of vapor barrier film is laid on top, the fixing method is the same as for the walls - on adhesive tape, fixing with a stapler;
a substrate is laid above to improve sound insulation.

Ceiling insulation

For these purposes, you will need the following materials:

vapor barrier film;
sealing adhesive tape;
kapron thread;
nails.

Work is carried out in the following order:

the vapor barrier is fixed on the floor beams and attic flooring by means of self-adhesive tape and a stapler, like walls;
at the bottom of the beams, nails are driven in at intervals of 20-30 cm, so that the hats protrude under the thread;
the foam is inserted between the floor beams and fixed with a zigzag stretch of the nylon thread between the nails, with a snug fit of the plates, additional fixation can be omitted;
the second layer of vapor barrier is fixed to the beams with a stapler.

Advantages and disadvantages

When using foam, it is worth considering the specifics of this material based on its strengths and weaknesses.

Provides excellent thermal insulation - thermal conductivity is only 0.037-0.043 W / K * m. In winter, heat does not come out of such a house, and in summer it is cool, hot street air again lingers outside. Styrofoam creates the effect of a thermos and allows you to save on both heating and air conditioning.
It has excellent moisture resistance and waterproofing, water absorption of a foam sheet for 28 days under water is about 3%, water vapor diffusion resistance - (p) for rigid foam plastics from 20 to 100 units.
High level of noise absorption.
Low price, one of the best available materials for thermal insulation.

Trying to speed up and reduce the cost of construction residential buildings, builders have come up with many technologies. In our country, the construction is again gaining popularity frame houses. Light "Canadian" houses are familiar to Russians for a long time, but only modern technologies made them suitable for year-round living. Warming frame house foam allows you to make living in it comfortable, regardless of the time of year.

The idea of such a house is simple. The vertical frame, connected by spacers and special strapping from the outside and from the inside, is sheathed with panels. The space between them is filled good insulation. It is from him that the climate and atmosphere in the house depend to a greater extent. Anyone can insulate a frame house with polystyrene foam.

Types of heaters

All materials that are used for thermal insulation in the house can be divided into organic and synthetic. Adherents of environmentally friendly materials mistakenly believe that organic is healthier, more reliable than synthetics. They forget: sawdust, shavings, other natural insulators can insulate the house, but they are afraid of fire. They also love insects. So that the natural heat insulator does not rot, is not afraid of fungus, pests, fire, it must be treated with several additives. Natural purity after such treatments is no different from the purity of materials obtained synthetically.

Expanded polystyrene (styrofoam), stone, glass or mineral wool keep heat better, are not afraid harmful effects. Each of these heat insulators is good in its own way, each has disadvantages. If you focus on the price, then the most affordable is polystyrene - a material obtained by foaming plastic. Ease of manufacture, inexpensive raw materials provide foam with the most low price among all heaters.

Classification of foam by production method

There are two methods for producing foam. In the first, the plastic pellets are sintered under the action of high temperatures. Such foam can also be used for insulation from the inside, but this option will not be the best. Styrofoam, consisting of many balls, is more often used as packaging for household appliances.

The second method involves pressing the granules. Insulation with this material is the most common: it is strong, durable, almost does not break, so the insulation of a building with such a heat insulator is more reliable. The material can have different viscosity, density, therefore it is divided into grades. In order to insulate a frame or any other house, it is better to choose PSB-S-15 or PSB-S-15. These grades have an average viscosity, they are quite suitable for warming vertical surfaces because they have an average mechanical strength. If you need to insulate floors or plinths, it is better to choose foam with a higher strength: PSB-S-35 or PSB-S-35. These brands can also insulate the walls of houses, but more materials are suitable for buildings that are under heavy load or are exposed to high humidity: roads, pools, floors in multi-storey buildings.

Polyfoam is divided into several types. It can be polystyrene, polyurethane, polyethylene, polyvinyl chloride. Wall insulation (both outside and inside) can only be done with polystyrene foam.

Why polystyrene is an excellent material for insulating the walls of a house from the inside and out

Insulation of a frame building with polystyrene foam is very beneficial, because the material has a number of excellent characteristics.

Affordable, the foam has very high thermal insulation properties. Buildings insulated with polystyrene foam will keep warm for many years without requiring replacement of the insulator.
Microorganisms can only multiply on the surface of the foam: they cannot penetrate inside.
Light weight does not require a solid foundation.
Expanded polystyrene is so weightless that it allows installation without the help of heavy equipment, even for one person.
Styrofoam does not decompose, does not rot, is not afraid of wind and temperature changes.
Does not require additional wind protection.
A building insulated with this insulator becomes practically soundproof.

For the walls of the house has some disadvantages. However, when correct operation they don't show up.

The material does not tolerate heat: it begins to release harmful substances. However, no one heats thermal insulation to temperatures that make polystyrene foam dangerous.

Expanded polystyrene is afraid of acetone, some other building aggressive liquids. But the insulation, located inside or on the outer walls, is not covered with either varnishes or paints.

Wall insulation with polystyrene foam: sequence of work

Warming can be done from inside the house or outside. The technologies are the same. Careful observance of them ensures that warm, cozy atmosphere, which neither wind, nor rains, nor temperature changes can spoil.

Proper thermal insulation is carried out in several layers at once, and begins with preparation. Removed from the wall paint coatings, nails, any extraneous inclusions. If the partition is uneven or made of bulk materials, it must be well plastered. The result should be a flat surface without depressions, cracks. Before it should be coated with a primer: this will improve adhesion (adhesive properties).
If the insulation is carried out in a building under construction, then at the second stage it is recommended to install external window sills and insulate the slopes. The ebbs are attached so that the window sill protrudes 3-4 centimeters beyond the wall: this leaves room for thermal insulation. In order for the slope insulation to fit securely with the wall insulation, it should not be cut flush: it is better if it protrudes 1 cm from the outer slope beyond the wall.
Before sticking the insulation, a profile is installed from below that fixes the foam. If the heater is placed on flat surface, the fixative solution can be applied under the comb. With differences of more than a centimeter, it is better to do this with blunders so that more solution gets into the recesses, and less into the bulges. So the plane will be smoother, so the insulator will be fixed on it more reliably.
The solution is also applied to the edges of the foam: on the wall it will disperse, fall under other sheets. The work is done from the bottom up.
Important: when sticking the plates, make sure that they lie in a checkerboard pattern, and the seams of the next row do not coincide with the seams of the previous one.
After gluing the last sheet of thermal insulation, let it stand for three days so that the glue dries.

The walls are dry: what's next?

As soon as the glue is completely dry, the foam is nailed. Holes are drilled at the corners of each sheet (departing from it 6-9 cm) and in its center, into which fungi are then inserted - special hats with sleeves. A nail is inserted into the sleeves. It is better if it is made of plastic: metal ones form cold bridges. It is easier to first insert all the fungi, and only then hammer in nails. This must be done so that the hats do not protrude above the surface.
The next stage is the foaming of the gaps between the foam tiles. They are formed due to uneven walls of the house, poor-quality trimming of foam. If the gaps are more than a centimeter, strips of chopped thermal insulation are put into them, and then they are foamed. Gaps less than a centimeter are simply filled with airtight foam.
After the foam dries, the joints and places where the nails are driven in are covered with an adhesive. Then the putty is rubbed so that a smooth wall is obtained.
Outside wall insulation completed. Now on foam wall attach the mesh. Start from the corners. It is better to fix special perforated corners but you can do without them. The solution is applied to the insulation, so the mesh is fixed on the wall so that about 10 cm lie on a clean insulation. The mesh is smoothed, the solution is added so that it almost completely covers the mesh.
The dried wall is rubbed again, then primed. Now you can start finishing the facade.

How to insulate walls with foam from the inside?

The frame structure will be especially warm if it is insulated not only from the outside, but also from the inside. They do it like this.

Important: all walls of the frame house should be insulated, and not just those that border the street.
A deeply penetrating primer is applied to the pre-aligned partition. It will dust the surface, allow it to better adhere to the adhesive solution.
As with external insulation, a basement profile is attached from the inside.
Prepare (using the same technology) a solution for work from the inside. Apply it to the thermal insulation, glue the polystyrene foam to the wall.
After drying, the foam is nailed with special nails.
Handle joints.
A layer of adhesive solution is applied, then the fiberglass mesh is laid and fixed.
Arrange vapor barrier. If the insulation from the inside was carried out with extruded polystyrene foam, then it is not needed. If the walls were insulated with foam of a different brand, then a vapor barrier film should be strengthened on top.
The resulting cake is primed, proceed to the finish.

More reliable, some experts consider the method in which finishing applied not to thermal insulation, but to additional wall from drywall. Such an additional partition allows you to use not only foam plastic for insulation, but also its variety - liquid polystyrene foam. In addition, additional air gaps between partitions also make the indoor climate more uniform.

What is especially important to consider when insulating with foam plastic?

Styrofoam is a material with uneven edges. Getting into the joints cold air can create cold bridges. This means that the wall will freeze through. That is why the joints should be sealed especially carefully.
The main problem of finishing walls with insulation from the inside is the transfer of the dew point. Moisture begins to condense closer to the inner wall, which can either ruin the plaster or destroy the wall itself. To prevent this, it is important to choose a reliable vapor barrier film. Only EPS (extruded polystyrene foam) does not need it. All other foams without vapor barrier are not recommended.

Wall insulation is a common practice. The work can be done independently, without the involvement of specialists.

Most Popular Blog Articles of the Week

Every day more and more more people want to live in own house. For this, plots outside the city are bought, and the construction of its own begins. small house. But building a house is usually colossal cash expenses, but not everything is so bad, today frame houses have become popular among private homeowners.

The cost of building such a building is much less compared to other structures. Indeed, at the heart of such a house is a frame, which is then sheathed and interior decoration is carried out. But the most important step is proper insulation such a structure, we will talk about this in our article.

The advantage of frame structures

Why is today frame structures are so popular among private homeowners, and why it is much more profitable to build such a house than from stone or brick.

As for the structure itself, this is, first of all, the foundation on which it is then installed wooden frame. After this frame is sheathed inside with plywood or OSB boards are used.

Here are some of the benefits frame buildings worth noting:

The price, wood-based materials are significantly lower in cost than analogues from which houses are usually built. The finished frame cottage at a cost differs from the same one built of stone by almost two times, to a lesser extent.
Construction speed. It usually takes builders two to three weeks to erect the skeleton of a building. After that, interior and exterior decoration begins.
Body and comfort, thanks to the fact that the structure is insulated modern materials, in such cottages it is much cozier and more comfortable than in stone houses.
Lightweight construction. Fully finished house by weight it turns out much less than all the same stone buildings. Therefore, it exerts little pressure on the foundation. As a result, the owners frame cottages protected from subsidence of the base and, accordingly, from the appearance of splits or cracks in the building.

But after all, the question of how to properly insulate a frame house with foam remains still open, and now we will deal with this not difficult process in more detail.

Frame cottage insulation technology

The construction of such a house, as well as the technology of insulation, is not complicated. When assembling the skeleton of the building, it is used in the installation wooden beam, he, in turn, is the walls of the whole house.

First of all, you should sheathe all the walls with thick plywood inside the house, and only then you can proceed to. With this approach, we have niches that are created thanks to the rack beam. It is in these niches that the insulation will go.

Finishing the house inside can also be called preparation for the insulation of the facade of the building, because it is simply impossible to carry out work without it. Sheathing the inner frame, we get turnkey solution for laying insulation.

Tip: it is also more expedient to insulate the loggia with the help of foam. The principle of laying is similar to the work on the insulation of the house.

Choosing a heater

Today on the market building materials There are two types of high-quality heat-insulating products. This is:

mineral plate;
Styrofoam.

We have chosen foam plates for ourselves, and we will work with them.

Why not use , you ask? The answer is obvious, the mineral slab shrinks quite often. After a while, it can settle behind the walls, and areas are formed into which cold air will pass.

Therefore, in our case, we will choose a polystyrene foam plate, and answer the question of how to insulate a frame house with polystyrene foam. But let us immediately note that self-insulation requires additional construction equipment, This scaffolding. They can be rented or assembled from wood, which in principle is very laborious and time consuming.

We buy insulation: choose the size of the foam board

In order to qualitatively perform the insulation of your new home, we need to choose a foam of the appropriate thickness. It is on these parameters that the thermal insulation of the walls of the house depends.

The thermal insulation properties of the material depend on the thickness of the material.

It will be technologically correct to choose foam plastic with a thickness of one hundred and fifty millimeters or more. You also need to take into account the width of the frame beams, the polystyrene foam plate should not be wider than the frame racks.

Looking ahead, let's say if the plate protrudes, then exterior finish facade you will spend with great difficulty.

Tools needed for the job

Accordingly, without necessary tools, such work will be difficult to carry out. So it is better to prepare immediately and then start warming your home.

So, what should be from the material in stock.

Scaffolding, they must be collected on the entire surface of the wall to be finished.
Construction knife, hacksaw with fine teeth. For cutting boards.
Construction mounting foam.
Roulette, building level

Here are the main tools you will need. If you need something else in the process, then it will most likely not be significant trifles.

Advice! If you are going to carry out insulation work with your own hands, then we will disappoint you. For one person, this is quite laborious. Therefore, it is better to immediately start working with an assistant.

We carry out work: installation of polystyrene foam boards

So we have come to the most important stage of work, now it is necessary to install the insulation in its place and fix it there. As you can see polystyrene boards, we will insert between the beams of the frame itself, strengthening it there.

So, let's proceed with the installation, and this instruction will help us with this:

We measure the width between the beams and cut the slab to the size we need, in width.
Insert the first sheet. He, like everyone else, should fit tightly between the beams and not have free play.
The installation of the heater must be carried out from the bottom up. This is done so that if you have an undercut, you put it under the base of the roof.
With a building level, check the vertical correspondence with respect to the plane.
According to this principle, the entire quadrature of the surface is laid.

Important! After the installation is completed, there may be gaps between the installed sheets, all these results are not perfect size foam sheets, and trimmings. These gaps are best eliminated with the help of construction. She will additionally open all the sheets and remove cold bridges.

Exterior decoration of the facade of the building

We have practically received an answer to the question of how to insulate a frame house with polystyrene foam, the insulation boards are already in place and fulfill their immediate task. But to leave, as you know, the house in this form is impossible. Now is the time to start finishing the facade.

House with siding panels

For these purposes, siding is the best suited, and we recommend using metal panels, not vinyl. Why exactly you ask, as practice has shown, vinyl siding not resistant to strong temperature changes.

Especially such panels are afraid severe frosts, after severe frosts, the panel loses its properties and may crumble. metal panels unaffected by temperature fluctuations.

Attention! Before installing the siding panels, it is recommended to close the insulation with a vapor barrier. This will protect the foam from moisture and create an additional heat-insulating barrier.

It is worth noting that in the case of finishing the facade of the building with siding panels, you will no longer need to mount the frame for them. The beams of the skeleton of the building will act as the profile for fastening the panels.

What other ways are there to finish the facade

Finishing the facade of a building with siding panels is, of course, not the only option for decorating a house. Knowing how to insulate a frame house with polystyrene foam, you also need to have an idea of what kind it will have. appearance.

This method is suitable for those who, for some reason, do not like finishing with siding panels. If this is the case, then you can use the block house finishing technology to decorate your building.

According to the principle of fastening, it is somewhat similar to the installation of siding panels, but the appearance is of course different. After the completion of the work, we get a house, the appearance of which is almost no different from a log building.

It is the block-house panels that give it such an extraordinary look. Typically, the price of such finishing material a little higher than siding, but the result is worth it.

Choosing this material, the facade cladding technology also changes slightly. In order to install the block-house panels, it is first necessary to sheathe the outer part of the building with OSB. Thus, hide the insulation under tight protection OSB boards and provide a foundation for attaching decorative panels.

Advice! If you veneer your facade in this way, after installing the sheets OSB plywood, be sure to go over the entire plane and blow out all the cracks with mounting foam. Remove all potential cold air bridges before installing the cladding material.

Now that you have processed everything qualitatively, you can proceed with the installation. facing panels. The principle of their installation is almost the same as when installing wooden lining. The panels are inserted into the grooves between themselves and then attached to the wall.

In practice, you already know how to insulate a frame house with polystyrene foam, now it remains to choose the technology and you can safely get down to business. By following these tips, you will definitely build a cozy and warm home.

Finally

We express confidence that the article will help you understand the principle of warming a frame house. And tips will help you avoid mistakes and unnecessary expenses. In the presented video in this article you will find additional information on this topic.

In order for the house to be warm, it is necessary to properly insulate it. It can be done different ways- synthetic wool, stone wool, expanded polystyrene, polyfoam and others. We will learn how the frame house is insulated with polystyrene foam.

What types are

Foam-based insulation is divided into several types. All of them have similar characteristics, but are fixed to the walls in different ways.

penoplex
polystyrene foam
penofol
liquid foam
actual foam

At the same time, the foam itself differs in density and function: there is foam for walls, there is foam for the base and foundation.

Consider the difference in foam density. The higher the density, the corresponding best performance He has thermal insulation. The standard density of the foam is usually in the range from 10 to 35 Kg/m3. Thus, foam grades are designated PPT 15 (i.e., with a density of about 15 Kg / m3), PPT 20, PPT 25 and PPT 35.

Please note that each of these brands is different in price, and also has its own scope. For example, PPT 15 is too soft, its density is low, so it cannot be used for floor insulation. The most versatile brand PPT 35, although it can be used everywhere without prejudice to the foam, however, its price is higher than the rest, so it will not be rational for it to insulate the walls from the inside of the room - it is too expensive. The denser the foam, the better it retains its shape, but the less dense foam is marginally warmer.

Thus, PPT 15 is used for roof insulation, PPT 25 for wall and vertical surface insulation, and PPT 35 for floor insulation.

How to insulate walls

Styrofoam is traditionally used to insulate the walls of a frame house, however, it is still better to use it to insulate the house from the outside, since the technical smell that the foam plates give off disappears from the room for at least a week. In the first week after the walls are insulated inside the house, residents may have headaches and sleep disturbances.

What you need to prepare the walls for insulation:

perforator
grater
paint brushes
bucket or other container for mixing mixtures
spatulas
needle roller
a hammer

To fix the foam, you need to make a flat surface of the wall, for which we remove old finish. After cleaning the wall from dirt, dust and other coatings, make sure that when applying foam sheets, there are no recesses and air spaces left. The foam should fit snugly against the wall. If the quality of the walls leaves much to be desired, it is necessary to primer. To do this, use a brush or spray.

With the help of a needle roller, we make the surface of the foam plate rough.

Important: we start gluing the insulation from the bottom, for which we set the starting bar. This bar will act as a support for the first sheets of foam, and will help to install them evenly.

Using a spatula, we apply the adhesive mixture to the insulation, after which we press it to the surface of the wall and press it with the palm of our hand. Do not use hard things that will damage the foam - only the palm of your hand. After installing the insulation, check for dents, cracks or damage.

In the same way, we continue to insulate all the walls, trying not to leave gaps between the foam sheets. When the work is finished, it is necessary to use special plastic nails, which experts call mushroom. Such a mushroom consists of a plastic circle and a sleeve-leg. Drive a nail into the sleeve, which is preferably plastic, this will avoid cold spots.

The fungus is attached thanks to holes made with a perforator. Hole length should be over size fungus 20 mm. On average, 5 fungi go to one sheet of foam.

Fungi are located at the joints of the plates, additionally pressing the foam sheets against the wall. Please note that the hats are flush with the insulation, and after driving in the nails, they are heated by 1.5-2 mm. If, after wall insulation, gaps of 5 mm or more remain between the sheets, they must be additionally foamed.

Subsequent wall finishing

How to make interior decoration after foam? So, you pasted all the foam sheets on the wall, foamed the joints and waited for them to dry. Next, you need to cut off the excess foam and check the wall for defects.

If any parts of the insulation stick out, they can be smoothed out with a grater. This is especially true for unevenly protruding places in the area of \u200b\u200bthe joints.

Use a spatula big size, and apply adhesive to the entire wall. Make sure the glue is applied evenly.

Paste plaster mesh to the heater. Since the glue dries quickly, we cut the grid in advance with a size of approximately 100x100 cm. A large grid may not have time to securely fix it. After the entire wall is pasted over with a grid, you can begin to apply a leveling layer. The layer should be about 3 mm thick, for this we also use a large spatula. After drying, grouting is performed, with the help of which irregularities are removed. The next layer is a special primer and a finishing layer. About ways interior decoration room read .

How to insulate the floor

Styrofoam has long been used for floor insulation, as it consists of millions of small balls of polystyrene, inside of which air is stored. At the same time, it is not afraid of moisture, does not change its properties for a long time, and has a suitable density (PPT 35) to withstand floor loads.

At the same time, foam insulation is carried out without much effort and knowledge, anyone can do it - not even a professional.

To begin with, as with wall insulation, it is necessary to prepare the surface for thermal insulation material. To do this, we clean it, close up cracks, insect passages, cracks, holes through which rodents can enter the house. Next, we lay a thick film on the floor, with the help of which waterproofing will be provided. This layer will prevent water from getting inside to the insulation. We lay the film with an overlap, which should be at least 10 cm, and glue the joints of the film with construction tape. Modern membrane films not only do not allow moisture to pass through, but also have water-repellent properties, while they also return heat to the room.

We lay sheets of foam on the film. It is better to use with profiled edges, which help to avoid cold bridges. Foam the joints, as the fixation must be reliable plates. If the sheets are not foamed, after a while the sheets will rub against each other at the edges, and make unpleasant sounds. Sometimes, in order to avoid squeaks, it is suggested to deliberately leave a space between the plates of 5 mm, which after foaming.

On top of the foam, we lay another layer of waterproofing, which will help prevent water from penetrating into the floor if something is spilled on the surface.

Next, we perform the installation metal mesh and doing a rough screed. We apply cement so as not to damage the film and move the insulation. Its layer must be at least 5 cm. Next, you can make a finishing floor.

If you have completed a frame house cement strainer on the ground, foam insulation is carried out as follows? We lay the film on the cement, then with the help of dowels we fix the foam plastic and process the joints with foam. Useful information on how to make underfloor heating in a frame house, you will receive in our article.

Remember: if there is a basement, it is better to insulate the floor in the house from the side of the basement. In this case, an additional layer of air is formed, and the floors will be warmer.

If you are performing insulation without a basement, do not forget that the surface on which the sheets are laid must be prepared. The screed must be perfectly even, for this we use a grid.

We insulate external walls and plinth

Most often, foam boards are used for external insulation Houses. Since it is not afraid of moisture, therefore it is preferable to use it instead of mineral wool. As we know, frame wall consists of several layers and last layer- OSB board.

It is best if the work is carried out in warm time years, since frosts worsen the properties of the adhesive, and the insulation boards will be worse. We fix the foam in the same way as we attached it to the wall. We use dowels after we glued a few sheets. They securely fix the sheets. And you can be sure that when the life of the adhesive ends, the sheets will not peel off.

To insulate the basement, we use 10 cm foam, since it is the basement that is the coldest part of the wall. Socle, using a reinforcing mesh, we process cement mortar. When the cement is completely dry, you can proceed to the exterior finish. The most commonly used plaster. If you have opted for lime plaster, you must add cement of a grade of at least 400 to it. We process the wall in two layers without intermediate grouting. We read about finishing the facade after insulation.

We make the roof warm

Since the roof also needs insulation, foam can be used for it, and PTT 15 is suitable, the softest and most inexpensive. The fact is that there is almost no load on the roof. However, it should be remembered that more rigid and dense foam will last longer.

Styrofoam is suitable for insulation, both inclined pitched roofs, and straight lines. In addition to the fact that the foam is not afraid of moisture, neither rots, does not deteriorate, it has high thermal insulation properties and, it is light, which is especially important when building a frame house. At the same time, foam sheets are easily cut, fixed with glue. They have good soundproof properties, thanks to which, during rain, the noise from drops falling on the roof will be minimal.

How is the insulation material installed?

The whole process can be divided into stages:

Laying waterproofing material on the rafters.
Fastening foam boards between or under rafters.
Sealing of seams with polyurethane foam to exclude cold bridges.
Laying vapor barrier inside the room.
Finishing internal walls and attic ceiling.

Foam boards are usually laid in the space between the rafters, while the laying should be tight, without cracks. To fit the size, the foam is cut with sharp knife along the ruler and break along the cut. The sheets are fixed to the rafters with the help of rails or glue for polystyrene. Fastening with glue may not be enough, so it makes sense to bind from the board. This design should hold the plates in several places. The resulting voids between the foam plate and other elements are foamed.

How to insulate a frame house mineral wool, read our article.

Currently, siding is used for exterior wall decoration quite often. Before the siding is installed, the frame should be insulated with foam.

Insulation with extruded Penoplex or mineral wool gives the frame house a number of advantageous features.

1 Advantages of frame structures

When insulating the frame with foam, on top of which the siding will be mounted, the house frame type significantly improves its performance. It improves:

Thermal insulation characteristics;
Noise isolation;
Vapor permeability;
Operational indicators.

Based on the fact that it performs a number of protective functions for such a heat insulator as Penoplex, it can be assumed that insulating a frame house with foam plastic from the outside or from the inside will be a rational decision.

The technology allows, as an alternative to polystyrene, to consider and subsequently use extruded polystyrene foam to insulate the walls of a frame house from the outside and from the inside.

For the same purpose, you can use mineral wool or Penoplex. Siding will be able to press the insulation from the inside to the surface of the walls with the necessary degree of accuracy.

To insulate a frame house from the inside with mineral wool, in order to subsequently place siding on the outer surface of the walls, it is necessary to take into account certain rules and recommendations.

In addition, siding provides a reliable level of protection for walls and a layer of thermal insulation. Currently, frame structures are very popular among most private homeowners; the construction of such a house is quite economical and profitable.

The design itself is quite simple, it consists of an installed foundation and a frame placed on it, made using wood.

Further installed frame sheathed with plywood or OSB boards (similar). It should be noted that the cost of wood materials used in the construction of frame houses is much lower than alternative analogues.

In addition, the already built frame-type house in terms of cost is much lower than the same structure built using stone or brick.

It takes only 14 days to build the walls of such a building. After that, the walls are finished from the inside. The whole structure weighs very little, which does not affect the strength characteristics.

This also contributes to a low load on the entire structure of the foundation of the building. All this suggests that frame-type houses are reliably protected from sudden subsidence of the bases, which can lead to the formation of splits and cracks.

2 Features of materials and insulation technology

The process of construction and further insulation of a frame house is not associated with any technological difficulties.

Based on this, it should be concluded that it will be quite easy to fix the siding and carry out the subsequent strengthening of the walls.

When assembling the frame of such a building, in most cases a wooden beam is used, which subsequently forms the walls of the future house as during installation.

In most cases, such a building is lined with clapboard from the inside, after which work begins directly related to insulation.

First, the surface of the walls is sheathed with a sheet of thick plywood. This takes place indoors.

At the end of these works, they begin the process of warming that part of the building, which is called the facade. When implementing such a campaign, additional niches may appear in some walls, which are created due to the fact that a rack bar is used during construction.

Further, all such niches are insulated with foam. Finishing of internal surfaces is made first of all, as it is necessary preliminary stage associated with the process of warming the front side of the building.

Continue without it further work(including the installation of siding) is strictly prohibited. When sheathing the inner frame, the owner receives a ready-made solution in order to lay the insulation.

Before implementing this type of work, it should be taken into account that the wall insulation scheme of a frame house consists of a certain number of elements. They are presented as:

load-bearing wall;
battens;
thermal insulation layer;
air gap;
membranes;
Siding.

Styrofoam is presented in the form of an environmentally friendly and harmless material. This insulation is characterized by ease of installation, it can be cut very easily.

At the same time, the foam has a high degree of ease of use. The presented insulation has a porous structure, which is formed from a large number cells independent of each other.

Expanded polystyrene has a low specific gravity and is characterized by high thermal insulation properties, mechanical strength and high parameters fire resistance.

Polyfoam is one of the highest quality thermal insulation materials. It perfectly combines the parameters of price and quality.

Plates of extruded polystyrene foam have high strength characteristics and are distinguished by a dense cellular structure of a closed type.

All boards are produced with a focus on the extrusion method, and at the final stage of production, a special foaming agent is added to the melted polystyrene.

It should be noted that extruded polystyrene foam is distinguished by a low thermal conductivity coefficient. This material is not capable of absorbing moisture and has increased compressive strength.

During production, special composite materials that are in the area high pressure. The use of fire retardant additives, dyes and all kinds of foaming additives, which are needed for the formation of gas in the internal structure, is relevant.

You can start installing siding at almost any time of the year. When installing siding, you need to pay attention to the air temperature, it should not fall below -10 degrees Celsius.

This is due to the fact that vinyl, when the temperature drops, can easily split during installation work.

All stages of work related to the insulation of the facade of a frame house are carried out in parallel with the installation of the crate on a brick or stone wall.

A layer of sheathing helps to hide obvious defects or irregularities on the wall surface. In order for the insulation to be securely fixed on the outer surface of the wall, first of all, it is necessary to assemble the crate, which is presented in the form of a frame.
