Useful tips on the insulation of the walls of the brusade house with their own hands. Technology of insulation of brusade house outside insulation walls of the house of a bar outside

Wood more warm material compared to brick or concrete. But in most regions, the thickness of the structures from it, satisfying the heat engineering, is significant. To reduce the necessary thickness use effective warming methods. Warming can be carried out both from the inside and outside. This article discusses how to warm the individual house from the bar outside with your own hands.

Advantages and disadvantages of conducting events on heat offering outside

The insulation of the house from the bar is intended to provide a comfortable microclimate in the room and prevent the destruction of the bearing structures under the action of cold. Protection of walls and other surfaces outside has the following advantages.:

the dew point (the location of condensate) is located on the surface, which does not allow moisture to get into the thickness of the structure;
protection from cold not only internal premises, but also carrying construction structures;
it does not decrease the useful area of \u200b\u200bthe room.

But this scheme has its drawbacks:

the complexity of working works by their own hands from the street with bad weather conditions and at a significant height of the building;
the need for additional finish of the facade (siding).

Many choose a bar as the material of the walls because of its appearance. When insulating outside, siding will close the logs and the original surface of the walls will be visible only from the inside. Outdoor insulation correctly apply from the point of view of science, but the owner of the house it does not arrange. If necessary, keep the initial facade of the building better to apply the heat protection circuit from the inside.

Materials for work

The insulation of the brusade house can be performed using the following types of heat insulator:

mineral wool (basalt or glass);
insulating foam;
warming with extruded polystyrene foam.

The easiest way to spend works on the warming of walls with your own hands withpolystyrene foam(foam or extruded). To work with this material, no special skills and special means of protection are required.

Foam insulation

The insulation of foam with its own hands has the following advantages:

low cost;
ease of installation;
the possibility of applying under siding without the air layer device;
high thermal insulation characteristics;
the durability of the heat insulator;
stability of foams to biological influences.

The disadvantages include:

combustion;
low strength;
instability to wetting at low temperatures (possibly destruction);
when the walls are insulated with foam outside, it is necessary to use siding or other durable material as a finish;
low vapor permeability requires an attentive attitude towards ventilation of the premises.

Some lack of insulation of foam can be avoided when using its closest relative. Warming with extruded polystyrene foam with its own hands has a higher strength and moisture resistance. Thanks to the addition of special antipyrin substances, manufacturers have achieved a combustibility class for some products G1 (weaklyor). The last two lack of thermal insulation by foam is also extruded expanded polystyrene foam.

Warming Minvata

The main advantages of the thermal insulation of the Ministry of Service can be attributed:

high degree of thermal insulation (low thermal conductivity);
fire resistance;
resistance to biological effects;
durability.

For a wooden house, it is best to use the heat insulation of the Minvata. In contrast to the previous two types of insulation, it does not prevent air movement through the design of the walls and allows the house to "breathe".

The following properties include disadvantages:

the possibility of scattering the material to separate fibers and enter these particles to the skin and in the lungs. The problem is relevant only for the installation period and is resolved by applying workers of individual protection;
compared to foam, the insulation has a higher cost;
the thermal insulation of the mineral walls can absorb moisture and lind under its own weight.

It is important to remember that the installation of this insulation outside the siding requires a mandatory device of the air-ventilated layer with a thickness of at least 5 cm.

Warming technology

Works on thermal insulation of walls under siding are carried out in the following order:

before insulationing a house from a bar, it is necessary to clean the surface from dirt and dust;
a pair barlasting device (can be skipped using extruded polystyrene foam);
installation of insulation;
fixing the waterproofing layer (for extruded material it is also not necessary);
outdoor finish facade.

Polyethylene can be used as vaporizolation, but it is better to purchase a special steamproof membrane.

Fixing the material depends on its type. The mineral wool insulation is attached to the wall on the dowel between the bars. The fastening of polystyrene foam is best to carry out adhesive compositions. This will ensure the maximum degree of thermal insulation due to the integrity of the surface.

Competent insulation of the house will avoid many problems during operation and significantly save on the heating of the building.

During the construction of bruschers in the context of the Russian climate, the insulation of the walls is a prerequisite for a comfortable stay. Our winters are too harsh, so the laptile building will force the owner to freeze or pay incredible amounts for heating. But when choosing materials for the walls of the walls, you want a tree to preserve your healthy microclimate. Unfortunately, many insulation, having high thermal insulation characteristics, do not "be friends" with a timber, cause it to "choke." And in a couple of years, lead wood to a deplorable state. Consider what materials it is worth carrying a brusade house, so that it is warm and the walls are ventilated.

What is better: the insulation of the house from the bar outside or from the inside

The main rule of the builder: to plan everything in advance so that later not to face alterations. Therefore, to think through the insulation of the house from the bar, start when creating a project. First, decide: inside you will sow or outside.

The favorably insulation of the brusade house from the inside

If the house is new, then many owners do not want to hide the texture of the tree under the trim, because it is beautiful in itself. In addition, the insulation of the house from the bar from the inside is beneficial to control the condition of the wood. The owner will have time to notice places where the walls will begin to collapse or rot, on time and take measures to "treatment" and enhanced wood protection.

Disadvantages of internal wall insulation

And yet, the warming of a log from the inside is used less often than the outer. First, it steals a lot of useful living space. That is why this moment must be thought out during design to calculate the square of the rooms with insulation. But if the foundation is already worth - you will have to put up with the fact that the premises will become closer, or to mount the insulation of the walls from the bar outside.

Secondly, the builders do not recommend warming the brusade house from the inside, because the tree will be in direct contact with the cold. And when winters will begin, the dew point will shift on the inner side of the wood. With the slightest errors in the ventilation, the tree will begin to rotes inside the cake, and you will notice it only when the fungus is projecting a boll through.

Advantages of outdoor insulation

The main trump card, which has the insulation of the brusade house outside, is the correct distribution of materials to exit internal vapors. For construction standards, materials are stacked from weakened to the simplicable. To pair, penetrating into them, could easier to weigh. The tree has a more dense structure, rather than the insulation (only correctly selected!) And the diffusion membrane, therefore steam does not fall into the thickness of the cake, but will disappear in the ventilation gap. In the case of an internal covering of steam through the insulation, it will be easily penetrated, and it does not always break through the tree, because it will time to cool, and the molecules will move weaker.

Making a choice in favor of outdoor or internal insulation, it is necessary to weigh all the "for" and "against" the selected method of thermal insulation

In addition, for old buildings in which wooden walls look no longer, the warming of a cut from the outside is a more profitable option. You will warm the house at the same time and embellish the finish. Well, the useful area of \u200b\u200bthe premises will not suffer.

Minuses of insulation Outside

If you decide to warm the house from the bar outside, you will lose the ability to observe the condition of the wood. Therefore, it is necessary to adhere to the correct installation technology and find professional builders so that the walls covered with the walls are stored healthy even without your control.

Nuances of internal warming of a church

If you still chose an internal warming option, then it can be made as safe as possible for the "health" of wood. To do this, it is necessary to buy a suitable, well ventilated insulation, whose vapor permeability and the composition will coincide with the properties of the bar.

The polystyrene foam materials disappear immediately: they weakly pass moisture. They cannot be used for internal, nor for outdoor insulation, because in places of connection with wood, condensate will begin to fall.

With a high level of heat resistant, polystyrene foam insulation are not recommended for wood, as they do not give the house to breathe

Basalt and fiberglass materials possess excellent vapor permeability, and with proper ventilation moisture will be distant of them. The only minus is an unnatural origin. All of them to some extent are distinguished by harmful substances, and in their structure there are many microparticles in suspension. When shaking the slab, you can see how the air is filled with the smallest fragments of the insulation, and they can settle on a person, causing unpleasant sensations. With normal ventilation, part of the weighing is found inside the house, and you will be forced to breathe them. If you block them out into the house with an impenetrable film, then all the healing microclimate of the tree will destroy.

When installing mineral wool, they use respirators, and you will have to breathe inside the weighted pieces

The most beneficial to maintain environmentally friendly air in the rooms will be linen fiber and soft fiber. Both insulation of natural origin, therefore, ideally suited to the structure of the brusade walls.

Eco-insulation for wood

Linen fiber

It is plates facing 85 percent of flax fibers and 15-binding fibers. Len is known for antiseptic properties that are stored in the insulation. Those. It will not settle fungi and bacteria. When cutting and installing linen, the insulation will not dust. Does not degrade its thermal insulation properties during the saturation of pairs, therefore, when laying does not require a vaporizolation layer. Well ventilated and does not cause allergies.

Flaxless does not contain suspended particles, so it will be safe to breathe in the house

Soft

It is made from chips of coniferous trees, forming into the stove environmentally friendly binders. Well absorbs sound and misses couples. It has a unique feature of drinking pairs during excessive humidity of the rooms and give them back if the air is reheated. Supports the maximum suitable level of humidity in the rooms: 40-60%.

Soft fiberboard - identical wood material, so they work perfectly in a pair

Some aspects of mounting

When using soft fiberboard does not need a doom. The insulation is glued to the bruster or take on the tapping screw. The wall is flat, so it is plastered, laying the joints of the plates with a reinforcing grid, and then color. You can immediately glue wallpaper immediately.

When using linen fibers create a vertical crate, stinging it directly on the bar. In it lay the plates of the insulation, fixing the dowel-umbrellas. At the top of the crates put metal profiles and sew the walls with plasterboard. Due to the metal profile in the wall, the ventilation gap is formed, through which the moisture that fell into the warmed bar will go under the roof or down and weathered. Note that when using linen fibers do not put parobaric films in order not to disturb the natural circulation of air.

How to insulate brusade house outside

Most often, we see in the video insulation of the brusade house outside. Mounted such a trim on the technology of creating ventilated facades, because the main requirement to preserve healthy wood is high-quality ventilation.

The choice of insulation in this case is wider than with internal trim. You can use any fiberglass or basalt insulation, because for their small particles the obstacle will be the glued bar itself. The main thing is to use plates, not rolls, because they are tougher and not fizzled down with time.

: Do not choose for mounting rolled materials, for over time they can landslide down

But before heating the house from the bar, decide on a specific heat insulator. For example, if you buy mineral wool, then when creating a wall cake, it is necessary to insulate the film from the bar, so that steam is not penetrating into the loose structure. Wet wool ceases to keep warm. But, fixing on the walls a vapor insulation layer, you thus reduce their ability to "breathe", because moisture from the bar will be forced to go back to the house. If you buy not afraid of wetting insulation (for example, eco-friendly or glass), it is not necessary to create vaporizolation. It is enough to protect the glued warmed bar with a ventilation gap from the finishing of the trim and the waterproofing film. Those. Your wall cake will look like this:

Bar.
Disease with eco-art inside.
Waterproofing film (superdiffusion membrane).
Ventilation clearance (Wooden rails are stuffed).
Finishing finishing material (lining, siding, etc.).

Rakes for ventilation are stuffed on the crate to be set exactly in terms of level: it will have to mount the lining or siding.

Choosing how to insulate the log house - outside or from the inside, weigh all the "for" and "against". Look for the option at which the wood will continue "healthy", and the rooms will become much warmer.

Houses from the bar, thanks to its environmental friendliness, are a popular private construction option. But although they quickly touch and have good thermal insulation properties, the insulation of the brusade house is an urgent need for most households.

Installation of insulation on the walls of the house from a bar

Differences between old and new technologies

Wooden construction in Russia is a centuries-old tradition. At the centuries at home, exclusively cutting, from massive round and semicircular logs, the thicknesses of which were enough for good thermal insulation. As today, the tree passed over time, and gaps appeared between the logs. But earlier there were other ideas about the beauty of the facade, so ordinary woody moss was used to constitute the gaps. He sat down in the creams between the logs and over time reliably filled out all the space between them.

In modern construction, savings issues go to the fore and make it use a bar, the thickness of which does not always meet the requirements of the developed standards. With an insufficient section, in the winter there is a complete freezing, and therefore, the walls of the house are not able to retain heat. In addition, over time, the tree begins to disappear, because of which the heat loss grow even more.

This looks like a wall of timber after timber sinking

Advantages and disadvantages of wall insulation in a brusade house

The maternity owners are looking for ways how to properly insulate a house from a bar to spend less means for heating in winter. This can be done in two main ways: from the inside and from the outside, and the external insulation for a number of reasons is preferable.

Features of insulation from the inside

With internal insulation, the positive effect of heat saving is leveled by disadvantages:

The part of the useful area is inevitably lost due to the installation of the frame under the insulation.

The heat insulating layer hides "live" Wooden walls and rooms lose their unique charm.

Due to the external winter cooling of the unprotected wooden wall, the dew point shifts into internal insulation. The formation of condensate occurs, mold appears, and control the state of wood is difficult.

What happens to the wall with improper insulation from the inside - on the video:

Wall insulation outside: the advantages and disadvantages of the method

Most often to it resorted, having in mind the obvious advantages compared with internal insulation:

The useful area of \u200b\u200bthe internal space is preserved;

External works do not change the routine of the family day.

The facade of the house is reliably protected from sudden temperature drops, which extends the service life of the structure.

The correct selection of materials does not violate the microclimate of the rooms (the house "breathes").

You can make a facade to your taste or improve the appearance if the wood darkened from time to time.

When compliance with wood, wood will be additionally protected from damage.

Easy control of the work of the construction team.

The main lack of outdoor insulation is the need to conduct it in good weather - when cold and damp, it makes no sense.

Three main methods of insulation

Any warming of the walls involves fastening the insulation layer on it and holding it with its designs. For this, several techniques have been developed and each of them has its advantages and features of execution.

The principle of insulation of the wall - the creation of an additional protective "cake"

Hinged ventilated facade

By itself, this technology is designed as an ornament of the facade of the house, but since the order of installation provides for mounting on the wall of the Minvat layer or a similar material, then this method can be considered as insulation.

Advantages of using ventilated facades:

Large service life (up to 50 years), excellent heat and sound insulation.

Easy in mounting.

A wide selection of facing material of various colors.

The dew point is shifted out.

Installation technology:

Pre-treatment of lumber is carried out by the compositions, which prevent rotting and make the tree unattractive for insects.

Outside the house is attached to the door, on which the canvas of hydro and windproofs are stitched. In the space between the layouts of the crates, the air freely circulates, due to which the condensation or an empty appeared from the insulation will be given away from the insulation.

The crate levets the level with a plumb.

Next, rails are stuffed on the crate, the distance between which should correspond to the width of the heat insulator. Accordingly, the height of the registers is also selected - for the middle strip of Russia, it is recommended to use a heater with a thickness of at least 70 mm.

The feature of the ventilated facade - the gap is left between the insulation and cladding

The mats of the insulation laid between the rails, fixing the dowels.

Then the rails are additionally stuffed with a thickness of no less than 5 cm so that the gap remains between the insulation and facing.

Mounted facing (siding).

Laying insulation under siding.

There are practically no fundamental differences from the previous technology - here the insulation is also used and the decorative coating is also used outside. But if the name of the ventilated facade itself speaks about the place of its use, then the whole house is closed by siding anyway.

Mounting nuances taking into account the selected material:

The distance between the rails is set to equal width of the mat if the foam or sheet extruded polystyrene is selected.

The distance between the rails is defined by 10-15 mm less than the width of the mat if mineral wool is used. This must be taken into account when calculating the number of minvati.

According to the technology of the plate from the wool mounted by Mosports; Polymer plates are placed in cells, butts are processed by mounting foam.

When using mineral wool, the waterproofing layer (diffuse membrane) is additionally mounted on top. It is not needed when using fiberglass or polystyrene.

Brous house lining siding

Polyurethane foam deposition method

The principle of this technology is clear to everyone who saw how they work with the mounting foam. The difference here is that the volumes of the material necessary to create a thermal insulation pillow are much larger, therefore, a spray gun is used to treat polyurethane foam, using compressed air from the compressor. Advantages of technology:

Simple use and high speed of the heat-insulating mixture on large surfaces.

Excellent adhesion (clutch) with most building materials, long-term storage of properties.

Ecology, fire resistance and protection against rotten surface rotation.

Deposition of the insulation can be made on any prepared surface

Types of insulation

The choice of insulation in external work is quite wide and each of them has distinctive features that need to be considered when choosing:

Mineral wool

Produced in three varieties - stone (basalt), glass and slag. All have similar properties: fire-resistant, non-combustible, possess chemical and biological resistance. Even the benefits of material include vapor permeability, environmental friendliness and high sound insulation.

By cons - wool attracts rodents and during wetting does not dry completely.

It all depends on the skills of builders, but usually the insulation of the house outside the Minvata is easier to spend using mats than rolls - the latter is not always convenient to deploy on vertical walls.

Laying Plates of Minvati in the crate

Styrers slab (foam, polyurethane foam)

Polyfoam is the cheapest option, lightweight and porous, low hygroscopicity and excellent thermal insulation. The main disadvantages are to be combustion (it allocates toxins during burning), fragility and instability when exposed to ultraviolet.

Extruded expanded polystyrene foam

It has a special porous structure, well tolerates low temperatures and is unsuitable for microorganisms. The material is durable, convenient for mounting (plates), does not absorb water. Disadvantages: Easily flammable and at the same time harmful toxins.

Polyfoam and polystyrene foam externally similar

Environmental sprayed styrenes (Equata and Polyurethan)

Such insulation roads due to the method of application; For processing large surfaces, special installation and experience is needed. For small areas of complex shape (cracks near pipes, windows, between the plates) are offered polyurethane insulation in cylinders.

"Warm" plaster

A mixture of light granules of complex composition (glass, cement and hydrophobic additives), which is not ignited, not afraid of ultraviolet, protects the facade from moisture well and is easily repaired.

Sounds of insulation of walls from a bar

The insulation of a brusade house outside under siding cannot be started when it wants - before that it is necessary that the following conditions have been completed:

Installation work of the insulation can be started only after complete shrink shrinkage - often this period can be one and a half or two years.

It is forbidden to carry out work if the facade was not processed by an antiseptic. Ignoring this rule will lead to the appearance of fungus and rot.

Before insulate a house from a bar outside, it is necessary to prepare the facade: to close not only wide slots, but also small cracks. To do this, you can use putty, mounting foam or similar materials.

Good thermal insulation of the brusade house requires a careful selection of material and the calculation of its quantity. It should be considered how the thermal insulation material will be combined with the tree of the bar himself.

To choose a suitable insulation, it is necessary to take into account the structure of the structure, the quality of the cut and seams.

Some insulation are installed without crate

Tools and materials for thermal insulation buildings

To insulate the house, without distracting the search for instruments and materials, builders need to prepare the following:

bubble or laser construction level, you can still use a plumb;

roulette, carbon or metal ruler;

hammer, construction knife or handcraft for metal, screwdriver;

facade dowels, scotch, chalk, mounting foam, antiseptic;

dry rails, insulation;

steam and waterproofing film;

material for final cladding.

wood processing sprayer protective compositions

Wooden Wall Processing Antiseptic

General installation of thermal insulation

All the steps on the insulation of the house from the bar in any of the described methods are simply equally the same and performed in the following sequence:

for ventilation of the first layer of the insulation, the wall is mounted on wooden planks;

the crate is hampering the frame for fixing the insulation

installation of insulation;

installing additional crates and frames (if double insulation is used);

laying of the addition layer of the heat insulator;

fastening the diffusion membrane, which will provide hydro and windproof.

installation of facade finish (lining, siding) with air gap.

In general, the warming of the house from the bar made according to the rules will give an opportunity to save in the future on heating. Despite the seeming simplicity of the whole process, there is a sufficiently large number of pitfalls that will definitely get out when installing. As a result - if there is no proper qualification, then the work is better to order professionals, because the construction of the construction is much more pleasant than to climb on the walls.

An ancient way to build houses from a wooden bar again became popular in our day. Now such buildings perform the role of not only country houses, but also full-fledged dwellings for year-round residence. Well, in order that in the wooden house it was warm in winter, it must be insulated. How correctly insulate the brusade house, we will talk in this article.

Warming of walls at home outside

As a rule, wooden buildings are taken to insulate from the outside. This allows not to engage the indoor space of the premises, and also does not allow wood to go. The insulation of the brusade house outside is necessary for several reasons:

The thermal insulation of the building protects the walls from heat loss, reduces heating costs.
High humidity, heavy frost and other unfavorable surrounding factors are not terrible home.
When doing thermal protection walls, you can simultaneously set siding, which will change the appearance of the house at the request of the owner.
As already mentioned, the outer insulation does not reduce the inner space of the rooms.

When performing such works, it is important to consider several points:

correctly select thermally insulating material, calculate its thickness and the required amount;
accurately comply with the installation technology;
do not forget about the creation of a hydro and vaporizolizing layer;
it is necessary to handle the wooden walls to protect them from insects, fungi, burning and other harmful effects.

The insulation for the brusade house must comply with certain requirements:

be qualitative and durable;
easy to handle and install;
safe for health, environmentally friendly;
do not burn.

So that the insulation of the brusade house was effective, and the construction served you for many years, listen to the following recommendations:

In no case do not use raw material. The insulation must necessarily be dry and pre-treated antiseptic. If the walls are covered with wet material, wood will begin to mold, rot, collapse. It will take fungi and microorganisms in it, and in time, the bars simply come into disrepair.
You can warm the walls of a wooden house only after a complete shrinkage of the building. At such a shrinkage, as a rule, takes at least 1.5 years. If you take the construction earlier, as a result of seeding logs, cladding is deformed.
Mount the heat insulating material can be only on the prepared walls. This means that all deep cracks and chips should be smeared with a putty, and the wood itself should be impregnated with antiseptics and antipirens.

How to insulate a brusade house outside: creating a mounted facade

Among the methods of thermal insulation of log buildings, the construction of a ventilated facade is considered the most popular method, the reason for this is the advantages of this method:

the mounted facade is easy to install, it takes a relatively little time to work;
after insulation, the wall can be bred by various decorative materials: clapboard, porcelain stoneware, siding, boards, rush profile, etc.;
this method of insulation does not allow the walls to mold and collapse, the dew point moves for the outer wall;
resistance to temperature differences, humidity, precipitation, as well as excellent sound insulation should also be attributed to the indisputable advantages of the hinged ventilated facade;
a similar design is durable, its period of operation reaches 50 years;
when insulation of the walls, you reduce energy consumption for heating.

The outer insulation of the brusade house in a similar way can be described as follows:

So that the moisture was accumulated in the wood of the walls, the gap between the insulation layer and the decorative finishing material is made, that is why such a facade is called ventilated. To create airspace on the wall set the crate. To make it, on the surface at the beginning put marks where the bars will be attached later. The width between them should correspond to the width of the sheets of insulating material, and the thickness of the BRUSEV is selected depending on the thickness of mats.
Setting the marks, the logs are attached to the walls using self-tapping screws. The accuracy of the fulfillment of the crates is tested by the construction level and plumb. It is especially important to ensure that all the bars are located in the same plane - this will help subsequently make a beautiful, smooth and high-quality siding.
When the elements of the crates are fixed, the insulation sheets are paved between them. They are tightly pressed to the walls and fix the dowels.
To ensure the necessary airspace, on top of the crate and the insulation layer nourish the wooden plank. The thickness of them should be such that the clearance turned out to be at least 5 cm.
After laying the insulation, finishing decorative siding finish.

Warming houses sprayed materials

Instead of leafy insulation, you can use and sprayed isolation, such as eco-friendly or polyurethane foam. Equata is a cellulose substance that is produced from recycled paper, boos and boric acid. The advantages of such a material can be considered:

environmental friendliness and hygiene;
good resistance to moisture;
excellent thermal insulation and sound insulation qualities;
fire safety;
non-toxicity;
uselessness;
excellent vapor permeability;
the ability to fill even the smallest slits in the walls.

Equata has the form of the crumbly mass, compressed in briquettes. Before use, such briquettes are opened, their contents are poured and dried it.

If you want to use polyurethane foam as insulation, check out the pluses of this material:

like eco-art, polyurethane foam fireproof;
it is characterized by good sound and thermal insulation properties;
it is considered an eco-friendly type of finish;
the life of its operation is quite long, and during the whole period the material does not lose its properties;
polyurethane foam is not subject to rotting, the mold is not formed on it, insects and microorganisms are damaged;
easy installation is due to the fact that it does not provide for the use of special fasteners.

For insulation of walls by spraying, you will have to get a special equipment. It can be bought, but you can rent and save money. The process itself looks like this:

Even before purchasing the material, it is necessary to calculate its required amount. For this, measurements are made of the area of \u200b\u200bthe working foundation, and the consumption of sprayed insulation is taken into account.
Then on the wall of the log house from the outdoor side, a crate of wooden boards or metal products is mounted. Subsequently, this crate can be attached to the decorative finishing material.
Using a special installation, between the bars of the crates are sprayed with water moistened with water or polyurethane foam. Often, when the wool is soaked, adhesive substances are added to the water, which will allow the insulation to hold on to the surface.
Processing the walls of the house with a pneumatic sprayer, the material is left to full pouring.
After that, the excess insulation is cut off with a knife, and siding is mounted on top of the crates.

Thermal insulation of the house from the inside

Is it worth insulating a wooden house from the inside

Few people are solved by mounting the insulation on the inner surface of the walls of the log structure. The insulation of the brusade house from the inside is not popular for several reasons:

This method of thermal insulation of the building can lead to the accumulation of moisture in the walls, which is why wood will hide, mold and collapse. It is extremely unwanted to use a similar method in baths and saunas, where the air is constantly saturated with water evaporation. In winter, when wood freezes, the dew point is located between the walls and the insulation layer, as a result, condensate accumulates there, which destroys the structure. If you create a good ventilation system in the house, then such problems can be leveled.
The second reason why the walls of log houses are rarely insulated from the inside, lies in the loss of useful area. The space of the rooms is reduced at least 3-4 cm on each side, and it is especially noticeable in small rooms.
The insulation layer also hides the natural beauty of the log cabin, which does not like lovers of natural interiors.

However, sometimes the owners of wooden houses resort to a similar method for various reasons. Some, for example, do not want to hide the appearance of the house under the layer of insulation and siding. Someone wants to bind the inner walls by any decorative material. Regardless of the reasons, the technology of internal insulation of the premises should be in good faith, so as not to spoil the wooden bars and not shorten the life of the construction.

The better to warm the brusade house from the inside

For thermal insulation of the inner walls, only eco-friendly materials should be selected that will not be separated into the air toxic substances. For example, foam for a similar purpose is not suitable for several reasons. First, it does not possess vapor permeability and does not allow the walls to "breathe". The room is absolutely insulated, it does not have a necessary natural air exchange. Secondly, the foam during combustion highlights very poisonous substances into the air, so in the event of a fire, it is considered extremely dangerous material.

It is possible to heat the walls of mineral wool. It is environmentally friendly and does not burn, has good vapor permeability, high thermal insulation characteristics. The most significant drawback of such a heater is that small particles representing the hazard for respiratory tract are distinguished into the air. If the wool is closed by a layer of film and finishing finish, then you can not pay attention to such a minus.

Very often for the inner warming of the walls are used completely eco-friendly and safe materials: flax, jute, wool. Such insulation means are economical and effective, protect the building from cold and foreign sounds, provide good air exchange through wooden walls.

How to insulate the brusade house from the inside with their own hands

First of all, you need to carefully examine the walls on the presence of cracks, chips, damage, the quality of cacopa. All disadvantages are eliminated, cracks are smeared with putty. Dirt and dust with logs are cleaned, after which the bars are impregnated with antiseptic compositions. If electrical wiring passes along the walls, it is also checked and, if necessary, repaired.
After drying the antiseptic impregnation in the walls of the gaps canopate. For this purpose, the jute fiber is used, which is shoved into the gaps using the chisel.
Before heating the brusade house, it is also important to take care of the creation of vapor barrier. So that the thermal insulating material is not impressed, it is taken from two sides to cover the layer of a steam insulating film. Because of this, the humidity in the rooms will increase, to avoid, you should arrange good ventilation in the house.
When laying a steam insulating material, it is placed in a smooth face to the wood, so that the moisture from the logs did not impregnate the insulation.
The next stage is the installation of the crate. Wood bars or metal blocks are stuffed along the bearing walls. The step between the boards should be equal to the width of the matte of the heat insulating coating. In the corners of the room mounted angular racks, so that the angles turned out to be smooth and beautiful. The crate is fixed on the walls using selflessness, with the help of levels check its evenness. If wood is used for the frame, it, like the walls themselves, are also impregnated with antiseptics.
Between the details of the crates laid the sheets of the insulation, for example, mineral wool. From the roll of the material, the fragment of the desired length is cut and installed between profiles or bars. It is desirable that the width of the sheet was 1-2 cm more than the distance between the parts of the frame. Running, cotton wool fills all the space and does not require additional fastening. If the insulation itself rests on itself not very reliable, you can fix it with a dowel.
From above on the Minvatu, another layer of vapor barrier film is stacked. Its fragments are laid out the mustache and in the fields of joints are connected by scotch. To the insulation, the vaporizolator is naked by a stapler. Remember also that the film needs to have a rough side to the inner space room.
The final stage of work is the finishing of the walls. The easiest thing is on top of the crates to install plasterboard sheets, after which they can be painted, cover with decorative plaster or caught with wallpaper.

Warming of a brusade house. Video

Built from a wooden bar, the house actually breathes, providing space inside a healthy microclimate.

A well-cocked facade often does not need additional insulation. However, it is carried out in order to save and savage used for energy heating.

In addition, cladding and effective insulation are one of the most relevant ways to repair no longer a new structure.

Preparation for insulation

Facade preparation

Insulation is carried out on the principle of the mounted facade. In the choice of the most suitable for this, householders often listens to the recommendations of friends and acquaintances.

It is important to remember about the dew point, which even the most qualitative insulation is able to shut down the walls.

And this is fraught with consequences: condensate is collected on the inside of the facade in the cold season. And it becomes the reason for increasing humidity, the appearance of fungus and mold.

Before starting work in the outer wall will have to highlight all the gaps.

If the house is new, then you need to wait at least a year, as they will appear after its shrinkage.

In the old structure, all angles and walls carefully check. The openings found are close to pacles or hemp, for which the chisel will be required. It is advisable to have them several pieces of different sizes.

Cracks in a bar can be filled with a special composition - a sealant for wood. The glued bar does not need meal.

Selection of material

After completion of the restoration work, you can think about choosing a suitable insulation.

Most often in its quality use mineral Wat or polystyrene..

The modern foam has its improved option - extruded expanded polystyrene foam. It is characterized by higher strength, even over time, it does not scatter into fragments and granules. Normal styrofoam From time to time is destroyed. Also, the improved type of material is distinguished by its ingrediability.

How to insulate a house from a bar outside?

Such a heater like mineral wool, perfectly ventilated. Thanks to this property, it does not lose its working qualities even during wetting (it absorbs moisture well).

When choosing a material for the insulation of the wooden structure, the features of the finishing materials are taken into account, thanks to which they can breathe like wood. It is of great importance.

The working properties of wood should not be violated, otherwise qualitative physical characteristics of the housing can change. Therefore, more often the choice does not fall on polystyrene foam, but on mineral wool.

The process of insulation of the house from a bar

How to correctly calculate the required thickness of the material for insulation

Before buying a material, it is required to make the calculation of the required amount of mineral wool. An important meaning is the thickness of the plates of the insulation.

Too thin is not only a violation of technology, but also sweating and wet walls inside the building in the cold season. Excessively thick material is fraught with unreasonably high expenses. When working, it is important to observe the following position: the dew point from the wall is outlined strictly into the insulation.

For this reason, the facade of wood is insulated only outside.

You can not do your own, rather complex calculations, and not to order them from professionals, but to refer to the requirements of a special SNiP, which defines all the necessary indicators for each specific zone.

It also indicates that if the wall has a thickness of up to 15 centimeters, then for mineral wool as a heater, 5 centimeters is quite thick. Material in 10 centimeters will be too massive.

To calculate the thickness of the insulation, you can use the uncomplicated folk method:

If the winter temperature indicators do not fall below 20 degrees of frost, then with a thickness of 20 centimeters, one layer of 5-centimeter mineral wool plates will be required.
If the winter is colder and the temperature often overcomes the mark of 20 degrees, two layers of the insulation of mineral wool are used.

Warming outside. Stroke work

Suppose we decided on the choice of material, and we know what thickness it should have. All subsequent work is carried out on a well-known mounted facade mounting pattern. This is a well-known technology.

The following manipulations have to be done:

Wooden timber is processed by special compositions - anti-health and antiseptic.
The lamp is mounted, for which the timber is used with a thickness equal to the thickness of mineral plates. The step between individual bars should be equal to the width of the insulation plates, which can be different - it depends on the manufacturer.
Mineral wool is located between the bars, it is reliably fixed to them with special self-drawing with umbrella hats.
Mounted wind insulation and waterproofing film. It is important to ensure that the film is placed in the right side: glossy outside, and Schezavva to the insulation itself.
After that, directly on the bar are tangible facing facade rails. Finishing can be made by different materials: it can be lining, block house, siding and so on.
It is also necessary to remember the observance of the necessary air gap between waterproofing and facing itself.

Such a technology provides for high-quality air ventilation of all available layers, which guarantees free evaporation of excess moisture.

This method can be used not only for the insulation of the facade of a wooden house, but also for the insulation of the roof. The roof can be coated with any suitable material, for example, functional flexible tile.

Paint for wood for outdoor work with waxing

The insulation of the brusade house outside is necessary not only to ensure the optimal climate inside the rooms, and to protect the wooden walls from the negative impact of the external environment. However, to ensure high-quality thermal insulation, it is not enough only to choose a material that will have a minimum thermal conductivity coefficient, and and possess natural properties. Is it difficult to insulate outside the house from the bar or choose the internal method?

The insulation of the facade of the brusade house outside has a number of the following advantages:

when conducting external work, uncomfortable conditions for residents of the house are not created;
the internal space of the premises is preserved;
additional protection of carrying structures from negative external factors is ensured;
ability to change the cover of the facade of the house without problem;
the service life of the building increases;
the dew point is beyond the limits of the main designs, so the problems of reference or the appearance of condensate are not terrible;
the natural properties of wood are preserved due to the optimal air exchange with the external environment.

The disadvantages of this insulation technology include:

work is permissible only under optimal climatic conditions: in the absence of precipitation and positive ambient temperatures;
the need for external sheaving or finishing, which may cause significant financial costs;
you can warm the facade of the building only after the period of shrinkage of the bar passed, namely, after 1-2 years after its construction.

Types of materials for insulation

The insulation of the walls of the brusade house outside can be performed using one of the following heat-insulating materials:

foam;
mineral wool;
extruded polystyrene foam.

Styrofoam

The outer insulation of the house of the bar of the foam is the cheapest way of thermal insulation. The material has a thermal conductivity coefficient of 0.03-0.04 W / m · to. It has increased moisture resistance (maximum absorption up to 1% of the total volume), so it is not formed mold and fungus on it.

The service life of the foam is over 20 years, so the maintenance of the insulated layer is not required during this time. When installing also does not arise any difficulties or problems, as the minimum amount of tool is used, the laying is performed quickly and efficiently.

Among other advantages of foam can be allocated:

optimal sound insulation;
minimum loads on the supporting structures, compared with other materials;
simplicity of sheet processing;
the possibility of applying a finishing layer directly to the insulation.

Mineral wool

The insulation of the brusade house outside Minvata is the most common way of thermal insulation. The fibrous material has a natural composition, so it can easily contact with wood. Due to the softness of mats can be tightly laid on the surface of any form without air gaps.

The thermal conductivity coefficient of Minvati is 0.077-0.12 W / m · K, depending on the type of fibers and plate thickness or roll. The density varies from 10 to 100 kg / m 3. The minimum life is from 20 years.

The insulation of the brusade house outside the stone car allows you to get the following advantages:

high soundproofing;
increased fire resistance;
not a tendency to damage by rodents or pests;
optimal vapor permeability and air exchange.

The use of extruded polystyrene foam (EPPS) is the most profitable and expensive, as it easily transfers the conditions of high humidity, external mechanical effects, contact with chemical and active substances. The term of his service up to 100 years, that is, there is no analogues today.

The thermal conductivity coefficient of EPPS on average is 0.03 W / m · k. The level of moisture absorption up to 0.4% of the total volume in 30 days. In contrast to foam of EPPS, the parapproxacity of 0.05 mg / m · pa · h and the homogeneity of the structure (granules with a size of 0.2 mm).

The plates density varies from 25 to 45 kg / m 3, due to which it is possible to accurately calculate the load on the walls. Compressive strength up to 0.16 MPa, and to bend - up to 0.25 MPa.

The main advantages of EPPS include:

resistance to sharp temperature differences;
environmental friendliness;
resistance to the appearance of fungus and mold;
chemical resistance.

Criteria for selecting material and requirements for insulation technology

Proper insulation of a brusade house outside can be performed by materials that meet the following requirements:

the optimal ratio of material and strength thickness, the minimum coefficient of thermal conductivity;
moisture resistance;
nonseasing;
in order for the weight of the insulation to withstand the carrying structures;
simplicity laying;
unpretentiousness in operation and undemanding for maintenance.

The requirements for insulation technology are as follows:

wood should be protected from external negative factors: temperature, moisture;
the thermal insulation casing should have sufficient strength, not to have a shrinkage and withstand sharp temperature changes;
all layers of material should not accumulate moisture, that is, be well ventilated, or have elevated waterproofing properties;
technological installation conditions should allow the specific method of insulation: the surface of the surface, the absence of explicit or hidden defects, the possibility of mounting the guides, etc.

An important role is also played by the conditions of operation of the insulation:

temperature range in a specific locality;
features of the building: fire hazard, the possibility of contact with various chemical and active substances, the probability of mechanical damage;
the minimum duration of the insulation operating under concrete conditions;
the need for maintenance.

Therefore, when choosing a material, it is important to take into account all affecting factors. Only in this case, you can ensure the maximum life of their operation and the lack of a problem with the bar. Also worth paying attention to the additional properties of the insulation, which will save on the laying of sound or waterproofing.

Features of the preparation of walls of the house to insulation

The technology of insulation of the brusade house outside requires the implementation of the following conditions and preparatory work:

the wooden house must pass the shrinkage period after the construction;
wood must necessarily be impregnated with antiseptics and protective impregnations that reduce the flammability and absorption of moisture;
all gaps and defects must be embedded, if necessary, you need to replace multiple logs;
it is necessary to take into account how the materials will interact with the bar to ensure the maximum possible service life.

Outdoor insulation of the brusade house

The insulation of the brusade house outside the outside can be performed by one of the following methods:

with the help of a mounted ventilated facade;
by deposition of the polyurethane layer;
encourage foam.

Installation of the mounted ventilated facade

Installation of the ventilated facade provides for the installation of the root with styling into the space between the insulation guides and the subsequent cladding panels. Mineral wool plates are used as thermal insulation material.

The main advantages of this technology are:

raising the level of hydro and sound insulation of the walls;
ease of installation;
minimum requirements for surface flatness;
a wide selection of finishing materials;
displacement of the dew point from the carrier structure into insulating layers;
simplicity of maintenance and repair of the mounted frame.

The implementation of the method is as follows:

Preparatory work is carried out: it is processed by impregnations, defects are removed, etc.
Mounted wooden or metal doomber in the width of the insulation.
The waterproofing layer is stacked.
The insulation between the guides is mounted.
The insulation of the windproof membrane is trimmed.
The counterclaim on the racks of the main root is stacked.
Putting with boards or decorative panels.

Warming under Siding

The insulation of the brusade house outside the siding has similarities with the thermal insulation technology by the method of the mounted facade. However, there are a number of features:

as a heater, you can use Minvatu or EPPS;
joints of thermal insulation and guides are closed by mounting foam;
when using minvati, a diffusion membrane is used as waterproofing;
when laying an EPPS, the installation of siding can be performed directly to the main cut, since the styling of waterproofing is not required.

Polyurethane layer spraying

Polyurethane spraying is an innovative method, the most efficient and expensive among all existing ones. It is with it that it is possible to form a hermetic seamless layer with high resistance to negative external influences: moisture, sharp temperature differences, pests.

The advantages of this technology are:

maximum protection of timber from rotting;
improvement of fire resistance of walls;
increased adhesion of the applied layer to various building materials;
lack of the need to align the foundation;
do not need fasteners;
increases sound insulation;
high homogeneity of the layer.

However, there are a number of negative points:

the complexity of applying a uniform layer;
the need to apply special equipment;
high cost of polyurethane foam;
instability to direct ultraviolet rays.

The method is implemented as:

The surface of the walls from dirt and various stains is cleaned.
Wood treatment with antiseptics and other protective compositions is performed.
Wooden guides are installed.
Polyurethane foam deposition is performed. If necessary, two layers.
Mounted trim.

Foam insulation

The thermal insulation of the walls of the foam is very advantageous and inexpensive, since the material is relatively cheap, is easily mounted and unpretentious in operation. In addition, the labeling of the dohes is not required, the finish can be performed directly on the insulation, with sharp temperature fluctuations, it does not lose its properties.

Polyfoam is a combustible material, so it is necessary to process wood with impregnation, increasing the ignition temperature or those who make it non-flammable (antipiren).

The insulation method is implemented as follows:

Mounted to the walls vertical lamb from wooden bars. Their thickness is equal to the thickness of the insulation, and the mounting step is the width of the plates.
The foam sheets are mounted inside the frame of the jack. The seams are sampled with a sealant or heat-insulating scotch. The foam foam is carried out on a dowel, called "umbrellas" or on the adhesive basis.
On top of the foam, the diffusion membrane jack is stacked. All joints are sampled special scotch. The mounting of the membrane is performed on the brackets with a stapler.
Mounted facing layer.

At the preparatory stage of the installation of foam, it is important to thoroughly align the walls, since with the slightest germs (more than 1.5 mm on the temporal meter) cracks can appear in sheets. In addition, it will save the layer of plaster on the flow rate.

For plastering walls, it is not required to install the cut, since the load of the decorative layer is minimal. However, there is one important condition - laying the reinforcing layer is necessary to increase the exterior gearing area and mechanical strength.

To make a house from a bar cozy, warm and inexpensive in service, reduce heating costs, then the methods of outdoor insulation are the most profitable. Their implementation is relatively simple, and the benefits of mass: reduced the cost of heating, protection of the carrying structures from temperature drops, pests, mechanical, physical and chemical influences.

When choosing materials for insulation, it is necessary to be guided by the thermal insulation requirements and a general budget for all stages of work.

Today we will talk about the insulation of the house from the bar. If a person lived all his life in Khrushchev or in a conventional brick house, he most likely does not represent all the delights of living in a wooden dwelling, as well as do not have the idea of \u200b\u200bcare for them.

One of the frequently asked questions about this concerns the fact that many do not know whether the insulation of the brusade house outside. In fact, wooden buildings can be very warm, especially from the cut, so the external selection is not always an acute need. The thermal insulation largely depends on the thickness of the material and the density of the connections between the elements.

According to the standards of SNiP for wooden houses of permanent residence, the thickness of the bar for construction is needed at least 200 mm. If the construction is used only as a summer cottage, then a thickness of 150 mm will be enough. But if you buy such accommodation for year-round use, then the outdoor insulation of the house is simply necessary to do.

At the same time, even 200 mm of timber will not save if the connections between the bars will be made incorrectly and the gaps will remain. There are some disadvantages of the material that can lead over time to the slots and cracks: with a bad drying, the profiled timber can be deformed, forming a slot in compounds, and the glued is more inclined to cracks from long-term operation, since it absorbs moisture well.

Therefore, thermal insulation of the house from the bar becomes relevant in such cases:

It is planned to update the appearance of the facade or change - to sew other material (most often PVC panels), which would simultaneously protect the wooden facade and supplemented the design of the exterior.
There is a need to reduce heating costs.
In the old facade there were cracks because of what the warmth is not held in the house.

Features of the heat insulation of a wooden house

In order for the heat-insulating work to bring a lot, and not just provoked spending, it is necessary to figure out how to warm the house from the bar outside before starting the insulation styling:

If the decoration with thermal insulation is planned to produce immediately after construction, it is desirable to wait 1-1.5 to the complete drying of the bar and shrinkage.
If there are slots and cracks in the facade, they are pre-closed with a putty for wood, mounting foam, rope from jute fiber.

Do not forget also about the processing of the wooden surface with antiseptics and anti-cartines.
The most ideal insulation for the wooden facade is the one that provides a dense thermal insulation layer. This must be considered when choosing.
Sewing a wooden house is better with lightweight materials, otherwise the walls and foundation will not withstand additional loads. Therefore, for these purposes, the PVC panels, a block house or lining are often chosen.

How to insulate houses from a bar?

Let's consider the variants of insulation for wooden buildings that are located in the list of popularity, and at the same time we learn how to insulate the brusade house outside with each of the materials:

Equata is applied using a special technology by a wet spraying (there is still dry blowing and a manual way, but this is easier and more convenient). 5-10 cm sufficient to the spraying bowl (the thermal conductivity of the EcoWhat 0.032-0.041). The layer is aligned on the crate and passes the dross, after which it is possible.

Minvata is produced in the form of plates. For warming under siding, there will be a 50 mm plate thickness (its warmth of 0.036). It is mounted using plate dowels.

Polyurethane foam is sprayed with a special PPU pistol with a tank in protective clothing and mask. Spraying thickness can be adjusted. It is better to make 2 uniform thin layers of 5 mm than one uneven. The thermal conductivity of such a material is 0.023-0.041, depending on the density of sputtering.

The polystyrene foam can boast of thermal conductivity indicators 0.038-0.041. It is provided in plates of various thickness, but it will be enough products with a thickness of 5 cm. Installation is made by special glue and mounting dowels.

Technology of external insulation of walls from a bar

For wooden buildings it is better to use, that is, when installing the crate and insulation, it is necessary to leave a small gap for the subsequent mounting of the trim. Stucco for finishing finishing in this case is rarely applied, and only if expanded polystyrene foam or foam for thermal insulation.

The cuttack on the wooden house for subsequent laying of thermal insulation and finishing finish is always made from the usual timber section of 50/50 or 50/60 mm on the prepared surface, that is, after sealing the slots, impregnating and markup.
Cells between the bars of the crates are filled with insulation on the appropriate technology of technology. Since the installation of the ventilated facade is planned, they do not forget to lay a diffuse membrane on top of thermal insulation, and then nourish additional bars over the already installed.
Now you can start the installation of finishing materials - block house, lining or PVC panels. For this use nails or self-tapping screws. Start from the installation of the lower panel, which is installed spike up. Self-tapping screws in this spike. Thanks to this, the mount will be hidden from the exposure to the external environment, which also looks more aesthetic.

If it is important for you how to insulate a house from a bar outside, you can not save on materials and choose polyurethane foam, which provides a solid dense layer of high-quality thermal insulation. But in most cases, there will be a dense ball of EcoWhat, followed by a thick block house.

The thermal insulation of the building protects the walls from heat loss, reduces heating costs.
High humidity, heavy frost and other unfavorable surrounding factors are not terrible home.
When doing thermal protection walls, you can simultaneously set siding, which will change the appearance of the house at the request of the owner.
As already mentioned, the outer insulation does not reduce the inner space of the rooms.
