Warming of timber house outside: technology, materials

Wood as a building material was known thousands of years ago. It is still used today. However, it is not necessary to assume that after the construction of a wooden house, the construction work is finished. Such a building, like any other, assumes the need for high-quality insulation. However, before starting manipulations, it is necessary to choose the thermal insulation, and also decide on which technology to install it.

Choosing a heater

The insulation of the timber house from the outside can be carried out using expanded polystyrene. If you compare with other heaters, it will be cheaper. In the case of mineral wool, the difference is 3 times. But the basic thermal insulation characteristics of these materials are almost the same.

Polyfoam copes better with the effect of moisture, the coefficient of its water absorption can reach a maximum of 1% of the total volume. Install this material is fairly simple, it can be easily processed even with a regular clerical knife. Its light weight allows you to move the canvas from place to place and raise to an impressive height.

Weight will not affect the design in the house. Styrofoam will not be able to load the structure, because it weighs almost nothing. You can use glue for installation, there are no special requirements for it, because everything again reduces to an insignificant specific gravity. If you decide to make insulation of the timber house from the outside, then you can choose foam, because he:

• Long-lived;
• Resistant to corrosion;
• Has a low water absorption coefficient;
• Can be used for work with your own hands.

As for the minuses, they have only two foams, namely, vapor permeability and flammability. The latter quality is the main stumbling block, when consumers choose thermal insulation. Although the tree is treated with flame retardants, it can catch fire. This process will be more rapid than if the analogous situation occurred in a brick or concrete structure.

Polyfoam is capable of supporting combustion, but modern manufacturers reduce its combustibility, treating the liners with flame retardants. The most successful solution will be extruded polystyrene foam. It is subject to the influence of fire, but it does not burn, which distinguishes it from traditional foam. Under the influence of flame, extruded polystyrene foam will melt and die out.

Using flax fiber

Flax fiber is a plate that is 85% composed of flax and 15% of binder fiber. Flax has antiseptic properties, which are stored in the insulation. This indicates that the material does not accommodate bacteria and fungi. When installing such a heater does not dust, it does not degrade its thermal insulation properties, even if saturated with vapors. Therefore, it is not necessary to use the vapor barrier during laying.

Alternative options

When deciding to make insulation of the timber house from the outside, you may prefer alternative options. Among them, it should be noted:

• fiberglass;
• Basalt mats;
• Plates of mineral wool.

Prefering mineral wool, you get a fairly light material, which, too, will not create additional stress on the elements of the building. The price of such material is not so high, it keeps the heat in the house quite well, and also is resistant to the effects of flame.

Mineral wool is quite elastic and soft, and it can be laid, eliminating the formation of cold bridges. If the insulation of the timber house outside is carried out with the help of this material, it will be possible to ensure the stability of the walls to thermal deformations. You can prefer fiberglass or basalt insulation, on sale there are also budget options.

However, they all work according to a certain principle, which consists in a loose structure that perfectly holds the air. Mineral cotton wool can be saturated with moisture and lose its properties, while glass wool and stone wool are devoid of such a disadvantage. However, if you create the right pie, the brand of insulation will not be important.

Warming under siding

Thermal insulation of the timber house outside under the siding suggests the creation of a wall pie. At the first stage, you need to choose the thickness of the insulation. Experts recommend buying a plate heater, giving up the roll insulation. This material has higher rigidity, and over time it does not slide down.

The thickness should be chosen taking into account the thickness of the bar. If the walls were erected from a 150 mm timber, a 100 mm insulation should be used. With an increase in the thickness of the wood up to 200 mm, a 50-mm layer of wool will suffice.

Laying the vapor barrier and installing the wire

If you decide to carry out the insulation of the timber house from the outside with your own hands, then the next step is to start laying the vapor barrier. This will protect the material from vapors that escape from the interior. The beam is treated with waterproof mastics, as an alternative solution, a vapor barrier film is used. This option is more preferable, because the quality of insulation will be higher.

To the wall, the film needs to be fixed with a stapler, by gluing the joints with adhesive tape. Thermal insulation of the timber house from the outside with a mineral wool suggests that the next step is the installation of a shed. A wooden frame is installed on the timber. From the metal profile should be discarded, because in the winter it will be colder than the wall, so there is a possibility of condensation. The cladding should be installed vertically, using the level and plumb line, because it will be mounted on it siding.

The distance between the beams should be chosen taking into account the width of the insulation. It is important to take into account also the step between the holes for fastening in the siding. The frame is treated with an antiseptic before installation.

Installation of insulation and installation of waterproofing

As soon as it is possible to form a crate, it is possible to start warming. To do this, basalt cotton wool is fastened using dowels-umbrellas. They should not be pressed too hard against the wall. Self-cutters will be a cheaper solution, their length should be 10 cm.

In order for the hat not to be drowned in the thermal insulation, it is first necessary to prepare the mugs from the plywood or roofing material, attaching them to the surface before installing the screw. On one square meter will take about 5 fastenings. Next, you need to protect the heater from moisture. To do this, a superdiffusion membrane is laid along the wireframe. Its surface consists of pores that look like funnels.

Creating an air gap and installing a siding

Thermal insulation of the walls of the timber house from the outside at the next stage implies the creation of a ventilation gap. On a wooden frame, 5-cm slats are installed to create a free space between the film and the siding. This will allow the moisture to evaporate and not settle on the membrane.

The air will move through the ventilation slots when installing the siding. Its installation should start from the roof, moving towards the foundation. Now the profiles are stuffed along the rails, they should be leveled, the work should begin from the bottom.

Thermal insulation with expanded polystyrene

Thermal insulation of the timber house from the outside with expanded polystyrene is carried out according to a certain algorithm. To conduct work is necessary on wireframe technology. Thermal insulation is installed in the dredging system. For additional fastening it is necessary to use glue, but some masters do not use dowels. First you need to prepare the surface, for this wood is treated with protective means. All the cracks must be punctured.

Next, the vapor barrier and the frame elements are installed. The heater is laid with the help of glue, in addition the canvas can be fixed with dowels. Now the second layer of waterproofing is laid, then you can proceed to the front trim. The technology of "warming the timber house from the outside" by this method involves the installation of two layers of insulation.

Conclusion

In order for the heater to perform its functions during the entire service life, after the purchase it is recommended to store it indoors. Open air is prohibited. If it does not tolerate the impact of moisture, then wetting will lead to a decrease in performance. If there is no need for fixing the insulation layer with the participation of mechanical elements, the distance between the rails of the lathing can be less by 20 mm compared to the width of the plates of foam plastic or mineral wool.
