Thermal insulation of the walls of a wooden house

Since ancient times wooden houses and construction of log wood are of particular value.They are beautiful and durable, and most importantly - are absolutely safe for the environment.In recent years, more and more owners are choosing to build cottages country houses tree.

Most of us dream of a vacation away from the bustle of the city, not only in summer but also during the cold season.Relax in a wooden house in winter is unlikely to succeed, because in these homes provided by district heating.That is why wall insulation wooden house is considered to be highly relevant.

Many people believe that if a house is built of wood, it should not be warm.On the contrary, it is like a brick, requires insulation of walls, so that the wood can not provide a good level of thermal protection.

When insulation walls on the outside of the wooden house owners will get a maximum of comfort.And if the house be protected, he changes in temperature, its service life will be significantly higher.

If a positive decision about the house warming, many people have questions - starting with, what kind of insulation to give preference to what materials to choose and how to perform their own works on warming of the wooden house.

about the advantages and disadvantages of warming

Often, when it is about the warming of the wooden houses, the experts advise to insulate the house from the outside.

This is due to several reasons:

• inner area is not reduced at home;
• wooden beam is protected against atmospheric precipitation and temperature extremes;
• through the layer of insulating material moisture can circulate freely and to go out;
• inside the house will remain a unique flavor and texture of the natural building material.

The disadvantage of warming the interior walls of wooden houses, experts note the following:

• floor area becomes smaller in the house;
• between the insulation and the wooden wall in the cool time is often accumulates condensate;
• if the heater is located correctly, the wall will be in the cold atmosphere - and that means that eventually it will start to crack, and the tree will be split.

In addition, warm wooden houses is necessary according to the specific technology.Thus, the insulating material must be placed on this principle - "withdraw moisture from the inside - out."Therefore, the first layer of insulation should be paroizoliruyuschim to the room did not get wet airflow.

After laying the first layer should be set the second - the thermal insulation.It will help preserve the warm air inside the house.The third layer - waterproofing, will keep moisture and will skip the pairs.

Warming inside or outside?

Before starting work, you must decide how to insulate the house - inside or outside.Wall insulation from inside the wooden house recommended in the event that the owner of the wooden house does not want the wall lost its natural appearance.But with this method, you must remember that the main wall, which is under the insulation, will remain in the low temperature.In this case it is likely that condensation will appear between the insulation and the wall, which may contribute to the growth of molds.

In addition, it is worth paying attention to as hardwood timber indoors.If the round does not overlap tightly adjacent to the wall, then in those places you can not install a heater.The language of the builders of the term referred to as "thermal bridges".In these places, the heat will be lost very quickly, and the heat loss coefficient is often greater than the heat indicators around the perimeter walls.

For external insulation of a wooden house, you can get a uniform temperature distribution over the entire area of ​​the wall.On the temperature regime and the accumulation of moisture affects the choice of insulating materials.Thus, dense materials are not permeable to water vapor inside the premises.Light and porous to be installed outside.If the wall is insulated on the outside and high-quality materials, it will provide high thermal insulation properties.

Types of insulation

Popular types of insulation of wooden houses:

1. Mineral wool.
2. Ecowool.
3. foam.
4. Penofol.

mineral wool - it's easy, fast and relatively inexpensive heater.

Benefits of mineral wool:

• does not burn;
• good "holds" warm;
• soft;
• elastic;
• just laid;
• withstand large temperature changes.

for insulation of wooden houses from the outside, the owners often use mineral wool.It is available in several versions: mats, plates and coils.

This material is well fills all voids.First, the frame is formed, which is filled with cotton wool roll.In addition, mineral wool fastened to the carrying frame is not necessary, it will hold well.

top of the heater is possible to lay a new board and perform home siding trim if desired.

Ecowool consists of an antiseptic and natural fiber - cellulose.She successfully stands the test of severe frosts and strong winds.

Among the advantages of this insulation are marked:

• environmental friendliness;
• prevents the formation of mold;
• this material will not be gnawing mice and other rodents;
• used to insulate the room from the outside;
• wall insulation under the "breathing";
• material does not burn, only smoldering, thus it does not emit toxins.

foams sheathe the interior walls of homes.Insulated with this material wooden wall outside the house experts do not recommend, because the foam is not breathable.Therefore, condensation may occur when the insulation inside the walls of a wooden house, molds, and the tree will be subject to decay.If wall insulation foam wooden house set first frame of rails to provide an air layer, and then attach the foam plate (thickness of one plate is five centimeters) with special solutions or fasteners.

methods insulating walls

In this photo you can see the order of the outside walls of the house insulation:

sequence of works is as follows:

1. Vapor.This layer will allow for ventilation under the film.If the facade is made of round logs, the material can be fastened directly on the wood, but it will form large gaps.If the surface is smooth, then it nailed slats (thick wooden slats - two and a half centimeters).The distance between each rack should be about one meter.For the vapor barrier should be prepared roofing paper, foil, and a special film.Materials on wooden slats fastened, providing the top and bottom openings for airflow.The diameter of the holes - two centimeters.Attention!In the field of fastening nails or staples for additional sealing.

1. For everything wooden frame used wooden board width of ten centimeters and a thickness of no more than five centimeters.Boards should be nailed vertically at a distance of one to two centimeters from each other.So it is possible to prevent the formation of voids and cracks.

1. Laying insulation layer.If the insulation you choose ecowool, then you must use extra zaduvochnoy machines, which will cause the material to the wall evenly.Remember that in this case laying isolating film is not required.When using plates, they should be firmly put in a wooden frame.To achieve this, it is necessary to choose the semi-plates, whose density is one hundred and twenty kilograms per cubic meter.To ensure a perfect seal material must be placed in a plate "staggered" manner.

1. Laying the waterproofing layer.To do this, you need to purchase a vapor-proof film, which will skip pairs, but do not allow to enter it on the heater.Installation of the film is the same as the installation of a vapor barrier layer.Upon completion of the board should be installed, which will allow to evaporate condensate falls on the waterproofing layer.In this case one can use a thick wooden slats from two to three centimeters wide - five centimeters.

To provide additional protection against insects and rodents, it is necessary to set fine-mesh metal grid.And in case of stacking the mineral wool, this condition should be performed carefully.

After completing work on the outer insulation of a wooden house, you should decide on the outer skin.You can fill the top wooden planks, boards of pine or oak.This natural building material to be processed and lacquering.

mezhventsevogo method of warming the house

Mezhventsevy insulation improves thermal insulation of the house, protects against damage and extends the life of a wooden house.A distinctive feature of this type of heater is that it must be laid between the wooden beams in the process of building a new home.

used for insulation tape insulation.It consists of natural material - flax, which combines perfectly with the tree, and at low temperatures, does not lose its properties.

Among the advantages of this type of insulation is dominated by the fact that the natural material is able to fill the log irregularities.If cavities are large, then in that case you can put two layers of insulation.You can also fill in the gaps that appear during the installation of windows and doors.

advantages of the material:

• has sound insulation properties;
• resistant to moisture;
• not rot;
• it did not form a mold;
• elastic;
• has high strength.

Among the shortcomings noted the high cost of insulation.In addition, if the house is located in an area with harsh climate, in this case, a natural insulation is not sufficient and should be additionally insulate interior walls or foam penofolom.

Wall insulation wooden house penofolom

Penofol - a laminate, which is classified as reflective insulation.It consists of polished foil (up to ninety-seven percent reflectance) and foundations.The base can be of varying density and structure.

standard material thickness may range from two to ten millimeters.In harsh environments you must use penofol 40 mm thick.

principle of operation is similar to the insulation work thermos.In winter it will be warm in it, and in the summer - cool.Moreover, the material will not trap heat inside the building, and it will reflect.

Advantages heater:

• environmentally friendly material;
• material is thin, so it will not climb the extra space inside for insulation of walls;
• not require additional installation vapor barrier materials;
• does not absorb moisture;
• has a noise proof properties;
• easy to transport;
• «not interested» rodents;
• is certified - the conclusion of sanitary and epidemiological stations.

From lacks experts say the softness of the material, so it can not be laid under plaster or fastened under the wallpaper.It is very difficult to mount a normal penofol (exception - a material with self-adhesive film) directly on the wall itself.

material fastened to the wooden frame using the furniture stapler.If you put the sheets overlap, you can get the opposite effect and the accumulation of additional steam on the walls of premises.

When installing insulation on the outside of a wooden house is necessary to prepare an air cushion consisting of a wooden frame and metal.After laying penofol on the surface, should be performed facing the building siding or other suitable material.
