How to insulate a house from a bar outside to create a

The climate in Russia is extremely harsh, the winters are cold, so the actual question is how to properly insulate a house from a bar outside. This work must be done very carefully, especially from the outside of the house, only then we will get the conditions for year-round living.

Features house building in Russia

Naturally, the question arises, how did they manage without the insulation of the house from the outside? After all, wooden houses were built in Russia since ancient times, they stood for centuries.

It should be understood that the old and reliable log house and a modern house from a bar are slightly different concepts. Until the 20th century, only chopped wood was used for buildings. Preference in carpentry was given to the ax, although the saw was known in Russia since ancient times.

But it was believed that the sawn wood absorbs moisture more strongly, swells and rot. And the wood in logs that are treated with an ax, as if clogged under his blows and does not absorb moisture.

Houses were built without nails, there were several ways to cut logs. The cups were cut down strictly according to the shape of the logs that fit in them, in the crowns they made a longitudinal groove for better log house density. Carefully caulked the joints of the logs.

All this gave the effect of solidity. The thickness of the logs in the log house was sufficient to maintain heat.

Another feature was the construction of a log house under the very roof, the construction of which in this case was called mats. This type of structure was especially widely distributed in the north of Russia. The logs were raised to the very roof, they built the triangle of the pediment, on which they fastened the slings for tesa.

So, we see the following features that did not allow traditional wooden houses to be made in Russia:

1. wall thickness sufficient to maintain heat;
2. solidity of the walls, achieved by the density of logs and caulking cracks;
3. low level of hygroscopicity of wood due to its processing with an ax.

Consider these features as applied to modern homes from timber.

Modern house of timber

For a normal level of microclimate in the house, when winter frost blows, it is necessary to build a house out of a bar with a thickness of 40 cm. If the cross section of the bar is smaller, it will not be possible to retain heat, the problem cannot be solved with a caulk of slots. After all, the timber simply by itself will freeze through in extreme cold.

In modern housing construction timber is used with a cross section of 150 mm, so this house has to be insulated from the outside or from the inside. The most appropriate to achieve the desired effect is considered external warming log house.

The level of hygroscopicity is reduced by treating the bar with special impregnations. With the help of various methods of outdoor insulation it will be possible to achieve the effect of solidity and sufficient thickness of the walls, the main thing is to find the right answer to the question of what is better to warm the house from the bar outside.

Advantages of outdoor insulation

The advantages of the house insulation method from the outside are as follows:

1. the internal space is not affected, it is possible to carry out works without breaking the usual rhythm of life of owners;
2. the ability to perform work on the insulation with their own hands, without the involvement of specialists;
3. the possibility of an original solution to the facade of the house;
4. heat losses are reduced;
5. external walls will be protected from the adverse effects of the environment.

Heaters

The modern market is rich in materials that are used for wall insulation:

1. basalt insulation;
2. glass wool;
3. Styrofoam;
4. extruded polystyrene foam;
5. polyethylene foam;
6. polyester fiber insulation;
7. sprayed polyurethane foam.

When deciding how to insulate a house from a bar outside, it is necessary to take into account many factors, take them into account and draw the right conclusions. In this matter, an important role is played by the price, quality and thickness of the insulation.

In order to make the right decision, it is necessary to consider all the comparative mechanical and thermal characteristics of insulation, given that the materials produced by different manufacturers, the characteristics may differ.

What features should be paid attention to when deciding how to insulate a bar-shaped house outside:

1. thermal conductivity index;
2. compressive strength index;
3. indicator of elasticity, elasticity (it is important to understand the ability of the material not to break when bent and restore its original shape);
4. to study the installation conditions (for each material the manufacturer’s instructions on how to install this heater are attached).

Council When choosing the thickness of insulation, you can face the choice that mineral wool insulation 50 mm thick will be insufficient for walls of 150 mm according to the requirements of SNiP 23-02-2003 "Thermal protection of buildings", and with insulation thickness of 100 mm will significantly exceed them.

In this case, you can use a combination of different heaters. For example, to use polyethylene foam, covering them with the facade directly along the vapor barrier, and stitch bars on it, between which to strengthen the mineral wool insulation.

The procedure for insulation work

Consider how to properly insulate the outside of a log house, what stages of work must be performed and in what sequence.

In order for the air vapor passing through the thickness of the beam, did not turn into water in the thickness of the insulation, it is necessary to make a vapor barrier. The best option would be to hold it from the inside of the walls by running from the foil material reflecting heat inside the room.

Consider how to insulate a bar-shaped house outside, when the interior has been completed and it is necessary to provide for a wind insulation device outside (read also the article Decorating a house from a bar inside on its own).

You must do this in the following order:

1. we fill the vertical crate on the outer walls of the edged board with a thickness of 40-50 mm;
2. we fasten the boards with a continuous sheet with an overlapping vapor barrier membrane;
3. we fill the second layer of the lathing on the same boards with a step suitable for the chosen heater;
4. we lay a heater between bars;
5. we lay a film or membrane for wind protection;
6. we fix a wind protection with counter racks;
7. Mounted on rails outer lining.

Important. Parobaryer walls should have air ducts arranged from below and above. This is necessary for air circulation and balancing the temperature in the area of ​​the gap and the temperature in the interior.

Warming a wooden house from a bar is an important stage in the process of reducing energy costs during exploitation and ensuring a high level of living comfort (read also the article Warming from the inside of a house from a bar: features, work order).
