Tips for proper insulation of the house from the timber outside

Reasons and advantages of external insulation

Houses made of timber and log are not to be confused, the building uses different technology, the material is also different.

During construction, it is necessary to use a beam with a minimum section of 40 cm in order to avoid freezing of the tree and keep the heat in the house.

Today, most often, a 150 mm thick bar is used. The difference in the cross sections is enormous, so it is necessary to insulate such a structure.

The tree has a high hygroscopicity, it must be treated with various antiseptics.

As for the insulation from the outside, it allows wooden materials to avoid contact with water in the form of precipitation, which has a beneficial effect on the whole structure.

What are the advantages of warming the house outside:

• during the work on the insulation of the house you can live without disturbing the habitual mode of life;
• the facade of the building can be decorated with any decorative coating;
• the installation of the heater is done by one's own hands;
• additional protection of the beam from the influence of external factors: precipitation, wind, temperature changes and other;
• the most important thing is the maintenance of heat, the reduction of costs for utilities.

Types of insulation

As a heater used a variety of materials that differ in their characteristics. What kind of insulation is better to choose? Consider the most popular.

Mineral wool - this kind of insulation got its recognition due to such properties as resistance to fire and the ability to "breathe".

The last factor is the most important for outdoor insulation of the house from the timber, as the walls are not exposed to rotting, fungus and mold formation.

However, the mineral wool with time lose its shape( crumpled) and useful qualities. If it is used, it is better to choose a plate-shaped view, not a roll or mats.

So it will be more convenient to trim and stack.

Penoplex is another type of insulation, which is great for a house made of timber. Penoplex differs strength, due to its structure does not absorb moisture, does not lend itself to rot.

There is an opinion that the foam is fireproof, but if you conduct an experiment and set it on fire, you can see that it is burning. It should be said that this material does not release toxins, it is environmentally friendly.

Of the disadvantages, it should be noted that with this material there may be difficulties in cutting, and also penoplex has a relatively high cost.

Penoplex and expanded polystyrene are the same material. The difference lies in the manufacturer, penoplex is a product of domestic production.

Polyfoam - the most common and familiar to all type of insulation.

It has a number of positive qualities: it does not swell, it keeps heat well, is resistant to temperature changes, etc.

Negative moments are also present: it has a low level of vapor tightness, which is not very good in our case, it is easy to burn and not environmentally friendly.

However, this type of insulation has the lowest price.

How to install the heater, see the video in the section.

Installation work

Any work starts with calculations. To correctly calculate the amount of material, you need to pay attention to the thickness of the beam and the climatic conditions of the residence.

For example, if in winter the temperature drops below the mark of 20 degrees, and the thickness of the beam is 20 mm, then in this case the heater is laid in two layers.

If the air temperature in the winter is not below 20 degrees, then it will be enough to lay one layer.

In addition to the insulation, a film is required for the waterproofing of the walls, it is lapped( + 10-12 cm), the board is 5x5 cm when using one layer of insulation and 5x10 cm - with two layers.

Houses constructed from a beam, shrink during the year, so work on insulation should be done immediately after construction is not recommended.

The initial stage of house insulation from the outside is the detection of all the gaps and their elimination. For this, it is better to use a jute fiber or a patch. The corners of the building are embedded more carefully.

Next, you need to treat the walls with antiseptic to prevent the tree from rotting and mold formation.

Antiseptic is better to apply with a brush instead of a roller, so that each centimeter of the wall can pass.

Thermal insulation of the house constructed of a bar is most effective, using the method of "ventilated facade".How is this done?

First, the boards are mounted around the perimeter of the facade. Install them vertically, the width of the step should be slightly less than the size of the insulation. Thus, a better fastening is achieved.

Then the space that has been formed must be filled with a heater( any kind of mineral wool, foam or polystyrene foam is suitable).The material is placed from the bottom up.

Stacking in the opposite direction will add additional trouble. The heater must be inserted with a slight pressure to prevent the formation of gaps.

The next step is to install a windproof diaphragm.

This material is overlapped and tightened, so when you purchase, you need to make a correct calculation of the flow, and when installing, eliminate sagging.

Over the top of the windproof membrane, boards are again installed, the step of which should not exceed 30 cm.

This is necessary for fixing the decorative coating. The boards are also mounted vertically, special attention is paid to the corners of the house, as well as the upper and lower boundaries, windows and doors.

Walls, zadekorirovannye siding, look beautiful, and installation is easy. The panels begin to be laid from the bottom, the installation implies the elimination of the formation of gaps.

To fix the discussed material, see the video.

General recommendations

The warming of the house from the outside is a responsible task, so do not neglect the following recommendations.

Keep the heater in the street is not recommended. This is explained by the humidity of the environment, which can have a harmful effect on the material.

The step of the curtain walls of the house must be somewhat smaller( 10-15 mm) in size of the insulation.

All work should be carried out in compliance with safety regulations: hands are protected by gloves, eyes - with glasses or a mask, etc.

Thermal insulation of the house from the bar is made after its shrinkage! The building shrinks within one year.

In order to ensure good ventilation of the walls, it is necessary to leave small slots on the bottom and top of the facade when building the building.

These places must be protected from rainfall on the walls with a visor.

The beam must be treated with antiseptics.
