Any sensible builder will say that no insulation can not heat, we understand whether it is necessary to insulate at all.

Covering the house with insulation is not cheap. The manager from the housing sector convinces you to agree to the insulation of the walls, they say it will help keep the heat in the apartment, but is it true, effective?

Any smart builder will say that no heater can heat and period. Let's see if we even need to warm up. Today's edition. "Site" will tell in detail about the absurdity of the use of insulation. The most common mistakes!



The heater is like a fur coat, dressed in frost, is not at all a source of heat. This material simply retains heat, but does not emit it.

Unfortunately, many do not understand this, and begin to use roll insulation, as they say, to the place and not to the place. Therefore, if there is no heat source, then no insulation will help - and the walls or roof will freeze.

Simply put, thermal insulation materials help the room to heat itself, just as a fur coat helps a person to warm himself. Insulation works only in the presence of a radiation source of positive temperature.

The basic criterion of any heat-insulating This is the coefficient of its thermal conductivity. The lower this value, the better the material prevents heat leakage into the environment.

To insulate the walls from the inside is a bad idea, since with the wrong selection heat-insulating You can reduce the service life of the walls themselves. In simple words, heat in this case is weak, but it will miraculously be converted into condensation between the layer of the insulation and the wall itself. As a result, the walls will gradually collapse.

If you turn to the standing norms and rules, then it is written in black and white that insulating the house from the inside, you shift the dew point inside the wall, moisture begins to condense in the wall.

Wall insulation For wall-insulation It is better to sew them with drywall. Each layer works on insulation differently... Thin insulation quickly heat up and begin to work on insulation, which accelerates the warming up of the room. The next layer of insulation due to the growth of its mass works slower. Also, mineral wool is suitable for insulation of walls from the inside, but condensate can not be avoided with foam.

Well, with a wall of concrete, brick or any hard stone stands heat up. Be sure to insulate the attic floor. To increase the efficiency of insulation of frame walls and ceilings, multilayering should be used. For example, from the inside there is paraisolation, then orgalitis, then a polystyrene membrane, and then a thick layer of stone wool, windscreen insulation ends.

So what? wall-insulate? It is, as they say, a matter of religion. The market has stone wool, ecowata, foam and polyurethane. There is still biotechnology, but in the modern market structure it is sectarianism. I do not see a fundamental difference, there are technological indications. Styrofoam - when it is necessary cheap, ecowata - when it is difficult to climb. Polyurethane is when you have a lot of money. In all other cases - mineral wool and again, denser-better.

Regardless of the type and type of material used as a thermal insulator, it must cope with the main tasks - insulation of the room, waterproofing walls, protection of the body. windy, as well as the preservation of heat. I emphasize once again the preservation, not the creation of heat!

The subtleties of insulation insulation It is important to adhere to the rule - moisture from human activity inside the room should not be absorbed into the walls. You need to have good ventilation, which is a separate issue. Based on this, internal walls can be mounted such airtight panels as, foam and others.

But from the outside, such an operation cannot be carried out. Here only moisture-permeable panels and insulation can be mounted. These are roll and panel insulation based on glass and stone. At the same time, the installation of cladding of external walls should take into account the natural convection of air between the cladding and the insulation.

And more: the most important thing is that there are no gaps (this is a special topic: membranes, foams). The insulation can be a meter thick, but if the wind finds a hole, then all the heat will blow out in windy weather. That is why it is dangerous to soak and track the insulation. It is a little sliding down, but it will form a gap (it will not be visible, of course).

Covering the house with insulation should be carried out by qualified and honest craftsmen. It's very important! As I was told by a familiar architect, you can ask the team of masters: “Guys, please make me 3 layers of insulation, dear ones.” And they wave their heads, they say, okay, we'll do that. And in fact, if you do not control their entire insulation process, place only 1 layer (the other two will sell) and make interior upholstery.

Everything looks good. And this "inconsistency" will appear in 15 years, for example. Insulation is the most “critical” construction site in the sense of cheating.

Editorial Board also suggest to familiarize yourself with errors in the insulation of the loggia. This idea requires good preparation and study of a huge amount of information!

Walls must. warm upProtect yourself from the cold outside. Therefore, on the question of whether the heater warms, we can safely say that it does not, since it does not create heat, but preserves it.
