Frame houses are deservedly considered healthy housing, since the main material of such houses is wood, which does not lose its relevance from year to year. Frame construction popular and developing in many construction companies, as well as in the private sector.
Frame house - perfect option affordable and attractive housing, and more than 20% of construction is now underway. Cost of materials and construction work frame house starts from 300-500 thousand rubles, which is much less than the cost of a small but full-fledged apartment. Even at such an inexpensive frame house can be created comfortable conditions residence, not only with the help of decoration, but also by creating proper insulation frame house.
Insulation of a frame house
After constructing the main structure, creating thermal insulation is the first thing to do. It is very important to choose the right type of insulation for a frame house.
Styrofoam
Foam plastic is the most common and cheap option to execute step-by-step insulation frame house. This material is easy to transport, but it is fragile and can break. The disadvantages of polystyrene foam include its fire hazard and the release of harmful substances during combustion and even simply when the temperature rises.
The frame is covered with foam plastic.
Insulation of a frame house with polystyrene foam is most often done due to low thermal conductivity, and this characteristic is the most important for insulation. Also, when insulating the walls of a frame house with polystyrene foam, you can save a lot on thermal insulation works and do it yourself. When installing foam plastic, you will not need to make a vapor barrier.
Mineral wool
Mineral wool is an excellent sound insulator and heat insulator, the most fireproof material for insulating a frame house with your own hands. However, it can absorb moisture quite well, deteriorate under its influence, crack and collapse.
Insulation of a frame house requires the installation of a vapor barrier, which is made from a special waterproof film. The joints of the film are overlapped and glued with reinforced tape or a special adhesive film.
Basalt wool Izover.
What you need to pay attention to when choosing insulation:
- Thermal conductivity.
- Fire resistance.
- Frost resistance.
- Noise insulation.
- Lifetime.
- Easy installation when insulating a frame house with your own hands.
On a note
It is better to insulate a frame house with mineral wool in the form of slabs rather than rolls, because breaks and damage will be excluded.
Other types of insulation
- Ecowool is a high-tech material in which there is absolutely no possibility for rodents and insects to live in it. The material is ideal for insulating a frame house from the inside due to its characteristics; its only drawback is the rather high cost of both the material and the installation procedure.
- – expanded clay, slag, sawdust. Good insulation, which is currently used more on flat surfaces. You can insulate the roof and floor of a frame house with the obligatory use of waterproofing, since it often gets wet, settles and requires replacement.
- Glassine is thick paper treated with bitumen. An excellent moisture insulator, great protection from the wind.
- Polyurethane foam is a good material that has a number of significant disadvantages - it is afraid of direct sun rays, high-cost insulation of a frame house from the outside.
- Penoplex - it contains extruded polystyrene foam. Penoplex is produced in rectangular slabs different thicknesses from 20 to 100 mm. Insulating a frame house with penoplex is justified by the fact that the material does not emit harmful substances. Like polystyrene foam, it conducts heat poorly, but it is much stronger and easy to process.
Mineral wool. Insulation of the walls of a frame house is carried out after the construction of the power frame and its installation under the roof. This procedure is due to the preservation of materials from getting wet. Especially if cotton insulation is used, which loses its heat-saving properties when exposed to water.
The video of insulating a frame house shows that mineral wool can also be installed for internal insulation of a frame house. Subsequently, the insulation boards are covered with OSB or clapboard. Additional insulation of a frame house made from the inside takes up part of the usable area.
Before taking measures to strengthen the walls of a frame house, it is necessary to carry out “ general cleaning", clean all beams and niches inside the frame of the house. Seal joints and cracks polyurethane foam.
Cross insulation
IN modern construction houses, it is popular to cross-insulate a frame house with outside. This method of insulation helps to get rid of cold bridges that occur at the points of contact between the insulation and the wooden frame. Also, wood itself is a bridge of cold.
Vertical cross planking. The usual thickness of the insulation of a frame house is 150 mm, which is placed between the frame posts. The insulation is used in the form of slabs, and its width should be one cm larger than the distance between the posts, which will allow the insulation to adhere more closely to the wood.
Additionally, horizontal bars of 50x50 mm are nailed to the outside of the frame, with a distance of 590 mm between them to tightly fix the insulation, the size of which is 600 mm. Next, a moisture-proof membrane is attached to the sheathing using a stapler and overlapped, and blocks moisture from entering the inside of the frame.
A counter lathing is nailed onto the moisture-proof membrane and then facade material, thereby creating space for ventilation and removal of excess moisture. A ventilated facade is created, which is simply necessary in the technology of insulating a frame house.
On a note
There is no need to steam and waterproof the outside - this will further damage the wood of the frame. It is important to leave a small distance between outer skin and façade to ensure better ventilation.
We insulate the ceiling. Insulation of the ceiling of a frame house
Before carrying out work on insulating the ceiling in a frame house, it is necessary to install a ventilation system and think through openings for the exit of all pipes.
From the attic side, or if the frame house is multi-story, a layer of foil foam is attached, also with a construction stapler, and layers of mineral wool are laid between the beams. Additional insulation there will be strips of glassine laid on top of the cotton wool and unedged board.
Insulation of floor and ceiling. Floor insulation
It is better to carry out insulation after installing the power frame of the house and placing the building under the roof to avoid getting the insulation material wet. done between the joists on the subfloor, another layer of insulation is placed on top, and then covered chipboard sheets or OSB.
Polystyrene foam or mineral wool can be used as floor insulation. It is not advisable to combine these two materials for insulation due to different characteristics. The thickness of the insulation of a frame house can be quite large, but then this should be taken into account already at the design stage and the necessary gaps should be left.
Pitched roof. Roof insulation
If you plan to equip it, then the roof insulation is carried out in rafter system. And if the attic is not heated, then insulation is carried out by covering the upper floor.
Insulation of the roof of a frame house can be carried out using inexpensive materials such as straw, shavings, sawdust. They are not expensive, but quite fire hazardous and susceptible to the development of microorganisms and fungal infections. Of course it's already last century.
We lay mineral wool in the frame of the house. Exists new scheme insulation of a frame house, which is based on the use of modern thermal insulation materials. Nowadays they prefer mineral wool, polystyrene foam, and penoplex. Also for flat roof You can lay bulk insulation.
Useful tips- The thickness of the insulation of a house built according to frame technology depends on where the insulation is intended. Typically, the thickness of the insulation is from 150 to 200 mm.
- The installation technology of the house indicates the presence of nicks and nails in the beams. To avoid damaging the insulation, it is recommended to clean and sand damaged structures.
- Before starting work on the internal insulation of the frame, seal the cracks and joints using polyurethane foam and pieces mineral wool.
If you decide to insulate a frame house with your own hands, step-by-step instruction on our website will help you understand the process and do everything with minimal costs. The price of insulating a frame house will depend on many factors, so first of all choose insulation and materials that do not require special skills and equipment during installation.
Frame houses are especially popular today: they are easy and quick to assemble, do not require a reinforced and expensive foundation, are inexpensive, and therefore accessible to all segments of the population.
Nevertheless, many do not dare to build houses using frame technology, since they consider them not warm enough and intended exclusively for summer living. However, this opinion is wrong, because if you approach insulation wisely panel house, you can feel comfortable in it at any time of the year. "But how to insulate a frame house for winter accommodation"- you ask. The answer to all questions related to the process of insulating such buildings will be our article today.
Insulation options
First of all, you need to decide where you will install thermal insulation - outside the building or inside. To accept correct solution, you should consider the features of each insulation method.
The following facts speak in favor of the external location of thermal insulation:
In the process, the interior of the house does not suffer at all.
Wooden walls accumulate heat in the room, and when the temperature drops, they release it back into the room, allowing you to save on heating costs.
It should also be noted that insulation material installed outside the house, in addition to its main function, reliably protects the facade from the harmful effects of moisture, ultraviolet radiation and temperature fluctuations. As a result, the service life of the building increases significantly.
If you are wondering how to insulate the walls of a frame house from the inside, pay attention to several disadvantages of this method:
For the internal one, you will need to dismantle the entire decorative finishing premises, which will have to be restored again after installation of thermal insulation. This leads to an increase in work completion time and additional costs.
With internal insulation, flows of warm and cold air meet inside the wall, which leads to the accumulation of moisture in the room, and as a result, the service life of wooden partitions is significantly reduced.
The insulating layer located inside the building does not protect the façade from exposure external factors. The wall goes through many freeze and thaw cycles, causing its structure to deteriorate.
Selection of insulation material
When asking the question of how to insulate a frame house for winter living, you should understand that when it comes to walls made of wood-based materials, the insulation must have the following qualities:
1. Environmental friendliness. The heat insulator should not release substances hazardous to humans into the air (even when heated).
2. Fire safety. You should choose materials that prevent fire from spreading along the walls of the building and do not emit a lot of smoke in the event of a fire.
3. Low thermal conductivity.
4. Durability. must fit tightly between the walls and retain its original shape over time.
5. Low cost. The price of insulation should not exceed the cost of the building itself.
Expanded polystyrene and mineral wool are considered to be closest to the above requirements.
Expanded polystyrene
The main advantages of polystyrene foam include its low weight, which is very important when it comes to frame structures. The material withstands sudden changes in temperature, is not afraid of moisture and does not freeze.
The durability and low cost of polystyrene foam attract many homeowners, but along with positive qualities this insulation It also has disadvantages.
These include:
Rapid flammability;
Susceptibility to mechanical and chemical damage;
Poor air permeability (which creates a thermos effect in the house).
As an alternative, many use an improved type of foam - penoplex, which is resistant to various kinds damage, but has a higher price tag.
Most often, this insulation is installed with outside Houses.
Mineral wool
The most popular material used as thermal insulation in frame houses is considered to be Isover mineral wool (insulation, the price of which, compared to similar materials, is quite low). On sale it is found in the form of rolls, mats and durable slabs.
It is characterized by environmental friendliness, light weight, excellent heat and sound insulation properties, the ability to bend around any irregularities, as well as long service life.
The fire safety of a material depends entirely on its density. Products in the form of slabs do not burn at all.
When choosing this insulation for frame walls, it should be taken into account that after some time the wool can cake and sag, which leads to a violation of the integrity of the heat-insulating layer. Also, due attention must be paid to waterproofing, since, when wet, glass wool loses its original properties and becomes favorable environment for mold to occur.
Facade insulation
Let's take a closer look at how to insulate a frame house for winter living from the outside.
For these purposes, you can use technology. It involves installing insulation between outer wall And decorative cladding. In this case, the thickness of the thermal insulation layer directly depends on the climatic conditions in the region of residence (20 cm or more).
This method can also be used for internal wall insulation, and lining or plasterboard can be used as finishing.
Technology of insulating external walls with foam plastic
1. The wall is cleaned of dirt and dust, all protrusions are smoothed out. The base is completely treated with a primer, and if cracks are found, they are covered with special adhesives.
2. Next, install vertical hangers. Nylon strings with weights are placed at a distance of 0.5 m from each other in order to identify and eliminate all irregularities (if the walls of the panel house are as smooth as possible, this step can be skipped).
3. Using special glue, the foam boards are fixed to the walls. It is very important that the material fits as tightly as possible to the base.
4. Finishing material is installed on top of the heat-insulating layer.
Insulation of internal walls
Now let’s figure out how to insulate a frame house with mineral wool.
Laying insulation should be started only after the wall has been treated with antiseptic compounds.
Installation of thermal insulation includes the following work:
1. Place a vapor-permeable one on the walls so that its smooth side “looks” into the room.
2. Guide rails made of wood or metal are installed on top of the membrane using self-tapping screws. The distance between the slats must correspond to the width of the insulation material.
3. Installation of mineral wool can begin either from the top or from the bottom of the wall. If you use rolled “Isover” (insulation, the price of which varies between 1500-2000 rubles per package), installation should begin from the ceiling. Mineral wool in mats is installed starting from the floor. Fastening is carried out using dowels with a wide head.
4. It is located on top of the insulation. For these purposes, you should choose vapor-permeable products that will contribute to natural ventilation premises. The film is fixed using wooden slats so that it is not too tight and does not sag. Next, the cladding is installed.
Conclusion
Now you know how to insulate a frame house for winter living. To conclude the topic, I would like to draw your attention to the fact that thermal insulation will not make the building suitable for living in the cold season - it is designed to keep warm air indoors. Therefore, if you want your home to be warm and comfortable even in severe frosts, take care of its heating.
Insulation of a frame house- a responsible process, which then determines how much you will pay for heating and whether there will be ventilation in your house, whether you can calmly walk barefoot even in winter and allow children to play on the floor for hours, or whether you will have to buy warm home clothes, socks and slippers.
I will define important concepts needed to understand the text:
Closing the outline of a house- this is the result of that stage of construction when the house is covered with a roof, doors and windows are installed in it, i.e. We are protected from precipitation from the street.
Insulation “by surprise”- this is insulation in which the pieces of insulation are wider than the cavity into which we insert it, which leads to the fact that the insulation supports itself due to natural expansion (we compress it so that it fits into the desired cavity).
Let's look at insulation various elements frame.
Insulation of the floor in a frame house can be carried out by the most different ways And various insulation materials. If your house is not built using USP, then this point is definitely relevant for you. I drew this diagram to immediately highlight all types of floor insulation in a frame frame:
Risk of insulating the floor of a frame house until the circuit closes is that during construction, moisture will most likely get into the insulation more than once (rains are not uncommon in Russia, but floors made of plywood or OSB still allow moisture to pass through), which means that the insulation may lose all its insulating properties ( unless, of course, it's foam).
Insulation of the floor of a frame house after closing the circuit is devoid of this risk, but it requires additional movements: either removing the floor already under the roof or climbing under the house and insulating it from there, or building walls without a floor at all and installing the walls of the frame house directly on the logs (not recommended, this is quite dangerous).
As you already understood, the floor of a frame house can also be insulated both from above (while on the floor) and from below (from under the house). Let's look at everything possible options and potential problems.
Option 1. Insulation of the floor of a frame house from above until the contour is closed.
Most traditional version. Immediately after securing in place, we can insulate the floor of a frame house before covering it with plywood.
If our insulation glass wool or mineral wool, then we just need to simply insert the insulation rolls spaced between the joists. The width of the insulation should be 1-2 cm larger than the space between the joists (if the insulation is 600 mm wide, then the joist pitch is 630 mm, and the space between them is 580 mm). If the insulation does not match, then we cut the insulation to the required size.
To simplify this process, you can first hem boards or plywood underneath the joists so that the insulation cannot fall into the subfloor over time. To do this, before installation, either cranial blocks are nailed to the joists from below, onto which the slabs under the floor insulation will be attached (picture 1), or they are attached, and under it, an inch with a pitch of 300-400 mm across the joists (picture 2).
Everything is simpler and more complex at the same time. It’s easier, because it’s not scary for it to get wet, which means it’s not scary to insulate the floor of a frame house with polystyrene foam until the contour is closed. Harder because it's tough and doesn't stand up to surprise so easy, it needs to be cut into Exact size clearance between the joists (or even place it against one joist immediately during installation and press it with the adjacent joist, then there will be no gaps). True, when the boards dry out (unless, of course, the board was already dry), most likely, gaps will appear between the foam plastic and the joists; it is better to foam this space (you can remove it from the underground later). You also need to hem something underneath the foam plastic (boards, plywood or wind protection). 
Option 2. Insulation of the floor of a frame house from below after closing the circuit.
If you have a basement or your house is on, and it is raised from the ground by at least 40 cm, then you can easily insulate the floor from below. To do this, you will need to prepare rolls of insulation, crawl under the house and place the insulation there at random. Then pull it under the insulation in the same way (or slabs supporting the insulation as in option 1). Remember that even if your piles are only 30 cm high above the ground, then adding a grillage to them, you get a distance to the floor joists of 50 cm, and this is already a completely working option for insulation from below.
Option 3. Insulation of the floor in a frame house from above after closing the circuit.
Insulating the floor of a frame house in this way is the most comfortable option, in my opinion. First we put the logs, secure them in their places, put ours on top, securing it TEMPORARILY with 2-4 self-tapping screws to the joists.
After which we put the walls on the plywood (but only load-bearing ones; we don’t put up non-load-bearing partitions at all yet), we put floor joists, rafters, etc. on the walls. until we close the entire circuit walls-roof-doors-windows.
Then we remove the screws from the plywood in the floor and cut out the plywood in the places where the load-bearing walls and insulate everything as in the first option (just don’t forget to add jumpers under the joints of the newly cut places in the plywood).
Order your home
There is another variation. If, before installing the walls, you place under them not solid sheets of plywood, but cut pieces 150 mm wide. In this case, there is no need to make additional jumpers, and there is also no need to cut anything, just unscrew the screws, remove the subfloor and insulate it.
Ecowool and floor insulation in a frame house from above after closing the circuit.
With ecowool everything is the same, only you need to attach a windbreak to the bottom of the joists or sew it up with something, because... ecowool is bulk and it needs a solid base (it also makes sense to use MDVP instead of wind protection in this case). A big plus of ecowool is that with it you won’t need to cut anything in any case, make a step under the subfloor slabs (and of course, under the required load).
At all, ecowool, In my opinion - best insulation for a frame house. If you decide to insulate your house with ecowool, contact me, I work with a real professional in insulating walls with ecowool, who travels to various regions.
Personally, for myself, I chose the option with ecowool.
Insulation of walls in a frame house
Insulation of walls in frame goes home in a similar way. We insert the insulation between the . Remember that the pitch of the racks should also be 20-30 mm greater than the width of the insulation. Typically, the pitch of the racks is 625 mm with a 40 mm board and 635 mm with a 50 mm board. By the way, it seems to me that it is better to trim OSB-3 a couple of times than to constantly trim the insulation.
Video about insulation of walls in a frame house from the Rockwool company (manufacturer of insulation of the same name):
What kind of insulation is there for walls?
Types of insulation for walls: mineral wool with a density of more than 30 kg/m3, ecowool (wet method) and polystyrene foam. These three modern insulation used in 95% of walls frame houses Russia. It is difficult to say for sure that the best thermal insulation for walls is ecowool or mineral wool or polystyrene foam, since each insulation material has its own pros and cons.
Insulation for external walls
Special external insulation for walls it is used if you want to make a plaster facade using insulation. In such cases, you have 2 options: polystyrene foam or mineral wool high density(about 125 kg/m3).
The cheapest and best insulation for walls
We can say for sure that the cheapest insulation for walls is mineral insulation with a minimum density, but it is not recommended to use it, although some take risks and even use glass wool in the walls of a frame house. Over time, low-density basalt can settle in the walls and cracks will appear.
In my opinion, the best insulation for frame walls is. That’s why we insulate the houses of our clients, and we haven’t had any dissatisfied ones in 7 years of work. Ecowool can even withstand fires.
So contact us, we will insulate your walls with ecowool. But we had to throw mineral wool out of the walls more than once because it had become unusable. Of course, it wasn’t her fault, she just didn’t follow the insulation technology, but ecowool forgives even that.
Cross insulation of the walls of a frame house from the outside
Cross insulation of the walls of a frame house from the inside
Insulate a frame house from the inside invented by the Scandinavians. In fact, it is much more convenient than outside, because... In this option, we are not afraid of precipitation and other weather disasters (in particular, hints from a neighbor). Insulation from the inside It usually also comes in horizontal lathing 40×50 or 50×50 with a pitch of 400-625 mm, only the lathing goes on top plastic film(vapor barriers).
Do not forget that the sheathing breaks at the openings: 
Insulation of the attic floor (ceiling) of a frame house
WITH top floor everything is the same as with the floor of a frame house, only there is no point in insulating from below, we do everything from above. Remember that you can pour or lay not only 150-200 mm of insulation (in the size of the floor joist), but also 300, 400 or even 500 mm of insulation. Walking on it will be problematic, but it will be very warm in winter and cool in summer.
Attic insulation
Video about insulating the attic with Rockwool:
Insulation of the basement of a frame house
It is convenient to insulate the base of a frame house with polystyrene foam or extruded foam plastic, which is attached to special fasteners.
So, in this article we introduced you to the most different options insulation of a frame house. This is a very important stage that can directly affect the health of you and your loved ones, so I urge you to take it responsibly.
And traditionally, I remind you about our services - you can buy a ready-made one from us or order its development according to your needs, and if you are still interested in insulation, we will insulate your house with ecowool or bring it.
The technology for building a frame house, which came to us from overseas, is gradually replacing all other types of buildings. Many advantages and a minimum of disadvantages brought it to the peak of popularity. More and more of our compatriots, faced with choosing the type of construction of their new home or cottage, give preference to it. Unfortunately, the construction of the box, covering the facade with facing materials, finishing inside doesn't make room new house suitable for living, because the climate in our country is very harsh. And in order for the home to be complete, and for its inhabitants to not have the desire to quickly move somewhere else, it must be insulated. In this regard, a logical question arises - how to insulate a frame house from the outside so that it becomes cozy and long years served his masters faithfully?
It is possible not to insulate a frame house, but in this case the owner must be prepared for exorbitant sums that will need to be paid for electricity and heating. And, of course, you shouldn’t expect the home to be quite cozy and comfortable.
External insulation of the house
There are several ways to install a thermal insulation layer during construction frame building. In some cases, insulation is filled into the gaps between the components of a frame building during the construction of walls. This method of arranging thermal insulation allows you to save usable space both inside and outside the building. In this case, the insulation is laid in a checkerboard pattern between the frame posts. The checkerboard pattern is needed to prevent the appearance of cold bridges in the heat-insulating layer.
In the event that it was not possible to carry out insulation at the construction stage, or the issue of thermal insulation arose after completion construction work, That additional insulation performed outside a newly constructed building by installing necessary materials on the surface of the facade.
It is best to choose material for insulation in slabs 5 cm thick. The total thickness of the layer, depending on the climate, should be from 10 to 25 cm. To protect the room from moisture and wind, it is used vapor barrier film, to prevent the appearance of moisture in the insulation - a superdiffusion membrane.
The vapor barrier film must be glued to the walls with an overlap of 15-20 cm. The seams are taped with moisture-resistant tape.
Choice of insulation
If the question of how to insulate a building had arisen in the last century, then there would have been no problems with the choice of material. At that time everything was done very simply. For this they used clay, straw or sawdust. They were used to make mixtures that were used to treat the walls. Now this type of insulation is not relevant and from the outside it looks, to put it mildly, comical.
Today the market is crowded various materials, and search suitable insulation may confuse an inexperienced and uninformed person in this matter. Therefore, it is important to know the characteristics, advantages and disadvantages of one or another material in order to find the most suitable one.
The following insulation materials are popular:
- mineral and ecowool;
- Styrofoam;
- polyurethane foam.
Insulation made of mineral wool and ecowool
Mineral wool is very often chosen for insulation. The material performs well in conditions high temperatures and combustion, it is lightweight and vapor permeable. Installation does not require much effort or special skills.
Quite often ecowool is used for insulation. You can buy it in briquettes. One weighs 15 kg. Before use, it is loosened, and then poured between the frame posts and compacted.
Over time, shrinkage of the material may occur, leading to heat loss. This is a disadvantage of ecowool.
Using foam plastic for insulation
The main advantage of polystyrene foam is its low weight, making it very easy to work with. The sheets are mounted without much difficulty, and in the future they do not affect the environment or people.
A huge advantage of polystyrene foam is that it does not rot or be affected by bacteria or fungus. Once installed on the wall surface, there will be no need to cover it with film.
Also among the advantages of this material is its low price, which allows you to save a lot on insulating a frame house.
On the other side of the scale is such a significant drawback as susceptibility to combustion, during which many harmful chemicals are released into the environment.
You can replace polystyrene foam with a flame retardant variety called extruded polystyrene foam.
Application of polyurethane foam
Insulation with polyurethane foam is performed by spraying onto the surface of the walls of a frame building. This option provides the highest quality thermal insulation among all others.
The application of a layer of this insulation is carried out using special equipment. All the necessary components are mixed inside the device, after which the mixture is sprayed onto the surface of the walls of the house. There, the polyurethane foam foams and turns into a solid state, forming a strong crust.
useful in work
The advantage of this insulation is the ability to apply it to almost any surface.
The disadvantage is that polyurethane foam is easily exposed to ultraviolet radiation, which means that if it is exposed to direct sunlight, it will lose its performance characteristics. Therefore, to prevent this from happening and to prevent the service life of the insulation from decreasing, you should not delay covering the facade facing material.
Preparing walls for insulation
Proper preparation must be done before any construction process. The insulation of a frame house is no exception.
If the building has already been in operation, then it is necessary to check the condition of all walls from the outside. All unnecessary elements must be removed from the facade, such as nails, screws, other construction elements, damage, bulges, etc. All such defects must be removed from the facade so that it is as clean and smooth as possible. All cracks that can be seen from the outside of the walls must be sealed with polyurethane foam.
You also need to carefully inspect the surface for damp areas. If there are any, they need to be dried using construction hair dryer, as well as take measures to find and eliminate problems that lead to such consequences.
For a frame house under construction, preparatory work also needs to be carried out. The frame of the walls is covered with chipboards from the inside. Then the process of removing defects takes place, as well as sealing the cracks with polyurethane foam. A vapor barrier film is applied to the inner surface of the walls to protect the insulation from air vapors emanating from inside the room. It then closes when interior decoration clapboard or drywall.
Facade insulation
Next, on the outside, on the surface of the walls, insulation is laid in layers. How many layers will be installed depends on the climate of the region. During installation of the material, each subsequent layer must overlap the joining seams of the previous one.
After installation is completed, the wall is closed windproof membrane, which is attached using construction stapler. Then a sheathing is constructed, which serves to provide a ventilation opening between the membrane and the facing material. The gap should be approximately 20-40 mm.
Particle boards are attached to the sheathing, after which the façade can be faced. For this purpose, siding, lining, etc. are used.
If this insulation turns out to be insufficient, then another one can be installed outside, applying an additional layer to the surface of the facade.
IN Lately Inexpensive construction of quickly erected housing using frame-panel technology is very popular among developers.
A frame house is assembled from prefabricated parts and does not require a massive foundation. Such lightweight designs have one drawback - insufficient ability to retain heat. Therefore, the insulation of such housing must be taken with full responsibility. What to do with isolating structural elements frame house is necessary both outside and inside the premises.
Features of thermal protection technology for wooden buildings
Thermal insulators are used to insulate wooden buildings. various types: synthetic and natural, with low thermal conductivity, high moisture resistance and fire resistance. For additional protection from exposure to moisture and rotting of the wooden parts of the frame house, waterproofing and vapor barrier are performed with membrane materials, thick polyethylene film or foil. Let's consider separately the insulation of each part of the building with our own hands.
Foundation and floor
The choice of foundation thermal insulation method depends on its type. The tape shallow support is insulated from the outside with rigid foam boards or penoplex. Concrete walls around the perimeter are dug out to the base, cleaned of dirt and coated bitumen mastic for two times. A 30 cm thick crushed stone-sand cushion is placed in the trench and compacted layer by layer. Then they are covered with polystyrene foam boards lateral surface base and lay a layer of insulation in the trench.
Then waterproofing is done with polyethylene film, a reinforcing mesh is attached and plastered. The trenches are backfilled with sand with compaction and drainage system corrugated pipe for drainage of soil and melt water. Then they do concrete blind area around the perimeter of the house. If there is a pile - screw foundation thermal insulation begins with fixing a waterproofing polyethylene film on the outside of the floor along the joists, which is laid with the condition that all seams and edges are completely sealed. From below to load-bearing beams stuffing the boardwalk. Mineral wool mats are placed between the joists on the subfloor and covered with an overlapping vapor barrier membrane, the joints are taped with reinforced tape. Then the finished floor is filled with boards or OSB panels.
Walls
To insulate the walls outside and inside, you can use slabs of mineral wool or extruded polystyrene foam and lay them in approximately the same pattern. The difference lies mainly in the choice finishing materials for outdoor and interior works. Here are step-by-step instructions for thermal protection of vertical enclosing structures:
- the walls are cleaned of old finishes, dust and covered with an antiseptic;
- covered with a waterproofing film, the sheets of which are overlapped and sealed with double-sided tape;
- mount wooden frame made of timber 50×50 mm, with cell sizes corresponding to the size of the insulation mat;
