Insulation should not be heated! Errors when insulating the facade of the house (where does moisture come from, mold on the walls)

There are different materials for home insulation on sale. Walls, roofs, pipes, partitions, screed, foundation, etc. are insulated with these materials. Correctly selected insulation will keep you warm in the cold and cool in summer.

To reduce costs, many decide to make their own insulation. But when there is little experience, you can make a lot of mistakes. As a result, this will lead to serious problems. Mold may develop and the house may rot.

Wooden houses need to be caulked before they are insulated. I remember how a neighbor's insulation was done as follows. He complained that after such work, the corners of the house began to freeze.

We attached a windproof membrane directly to the walls of a wooden house, and a wide profile was fixed on top. Insulation was mounted between the profile, and a windscreen was still stretched from above. Further finishing - siding. There was no ventilation gap. As a result, when they dismantled everything that the miracle workers had done in 2 years, they found that all the insulation is wet and the wind protection is all black from mold and mildew.

Another, more experienced team arrived. She pointed out the following mistakes in insulation. It turns out that the first layer (windproof membrane) is not needed at all. The insulation must be mounted to the walls of the house. At the same time, there had to be bars so that the insulation passed between them.

The wooden walls began to turn black. It is good that the first team did not use a vapor barrier instead of wind protection, otherwise the house rotted faster.

Siding must be mounted with a ventilation gap.

Another mistake is not to use the crate for the installation of insulation. Then you will need to pierce the insulation with suspensions and this ultimately violates the tightness. The lathing is also needed so that the insulation is held tightly, and there are no cracks.

Insulation as such does not heat

Don't believe me? Wrap a thermometer in insulation and see the result. Insulation only serves to keep warm. It is more expensive to insulate the house from the inside. The house will freeze even more.

If you use insulation from the inside, then only EPSP on walls made of foam concrete or brick. But if you apply this material outside, it will lead to wet brick walls, mold and mildew.

It is recommended to use insulation of 50-75 and higher density on the facade. If the insulation for the roof, then 30 and above.

Extruded polystyrene foam is great for insulating the foundation, basement. Basalt insulation is used for the roof and facade.
