How to insulate a building – outside or inside?

You can insulate the walls of the house as from the outside, as well as inside the building. Which option is the most suitable, which one is better to choose?

Before insulating the walls of a building, it is necessary to decide, how to do it better and more efficiently – insulate the house from the outside or from the inside, choose, how to insulate, and find out, how thick should the desired thermal insulation layer be.

What to choose?

Sure, Each option has its advantages and disadvantages, And people have very different views on this question. Isolation of the house from the inside can do cheaper, than outside, what can be very useful in the long run. However, when warming from the inside, the space is lost, It is also advisable to use vapor barrier, so that moisture does not moisten thermal insulation material, and a special ventilation system is required to remove the steam.

Today, much attention is paid to the ventilation of the building, so that the walls of the buildings breathe, They did not accumulate heat, because the materials available currently were not available in the past, and houses were built using another technology. Today, with the development and improvement of technologies in the field of insulating materials, It is necessary to use other insulating materials, than it was just a few decades ago.

External insulation

Buy building materials with delivery in Kyiv For outdoor insulation you can in the store "Isk". The advantages of this type of insulation:

• a continuous layer of thermal insulation is created without the formation of cold bridges in the partitions, antires and other designs;
• since the massive part of the wall is inside or in the heat, It has high thermal inertia, accumulated heat persists for a long time and slowly returns;
• The material of the outer walls, for example a brick or aerated concrete, not exposed to external weather conditions – Frost, rain and other precipitation;
• The total area of ​​the dwelling is not reduced.

Disadvantages of insulation of the building from the outside:

• insulation of the walls of the building outside is often more expensive, than insulation from the inside;
• It is best to insulate the walls outside the private, not an apartment building, If you are not planned to insulate everything, because it is impossible to heat only one apartment or a separate room;
• work can only be carried out under favorable weather conditions.

Both options are equally good and acceptable, but you need to evaluate the advantages and disadvantages of each option, To understand, What suits you the most in this case! Insulation outside the building – The most suitable solution in that case, when it is planned to comprehensive repair of the building, when it is also planned to repair the finishing layer of the facade, as well as during the construction of a new building.

When choosing insulation materials, it is best to talk with experienced specialists, who can help with advice. Sure, Nowadays you can find many tips and useful information on the bowels of the Internet, what is definitely worth thinking about.

If you insulate the building outside

The external walls of the building can be insulated with various materials, available in building materials stores – special heat -insulating plates made of polystyrene or mineral wool foam, as well as other modern solutions, such as hemp cotton wool and foam insulation of buildings. Depending on the surface of the base and construction of the construction, they are glued to the surface, Additionally fastened with dowels. A reinforcing layer is laid on top of the insulating layer, consisting of putty and built -in nets. The final part of the system – structural plaster or decorative panels.

How thermal insulation works?

Temperature fluctuations in an unenlightened external wall occur differently, than in isolated. The indelified wall cools quickly, Inside the building, air cools faster and be in such a building, which cannot maintain optimal heat for a long period of time, unpleasant. Hence, The outer wall is much colder, than the air temperature in the room. Due to the large difference in temperature, the walls get wet, can even form mold and fungus.

When warming the facade, the freezing point is transmitted by the thermal insulation system, Therefore, the temperature inside the wall is similar to the air temperature in the room. This makes the formation of moisture impossible, mold and fungus on the walls.

Foam instead of air gaps

Insulation of buildings with polystyrene and cotton wool has already become a traditional method of insulation of buildings, But another solution was added to these decisions – Filling the cracks in the outer walls of buildings with aminoplastic heat -insulating foam. This technology can be used as in previously built buildings, and in new buildings. Thus you can insulate the buildings, If the old isolation is worn out or settled, or if the wall of the building is walled up with brick, Leaving the air gap. Foam does not interfere with the wall to breathe, but violates free circulation of air. Foam is blowing into the air gaps of the walls, Filling them evenly, it does not increase the volume and does not "tears" the walls. Foam is also effective sound insulation.

In the outer wall, about each meter in a horizontal and vertical directions, holes are drilled. Usually they are made in the seam of the solution between bricks, Without damaging him. Thermal insulation foam is gradually blown through the holes, which completely fills the entire air gap. After insulation, the wells are sealed with a construction solution and aligned.
