For high-quality wall insulation, it is important to choose the right insulation material. In laying mineral wool and polystyrene have their own characteristics and rules.
External wall insulation is most effective, but internal insulation cannot be neglected. The choice of insulation is an important task, the comfort of living in the house depends on the correct solution of which.
Which insulation is better?
The most popular heat-insulating materials are mineral wool (stone, basalt, glass wool, ecowool) and polystyrene. All of them have worthy characteristics. But mineral wool has one drawback - high hygroscopicity. This means that this material is able to absorb moisture from the air. Therefore, walls insulated with such a heat insulator need high-quality protection: installation of both waterproofing materials and vapor-permeable membranes is required.
When using foam, such problems do not arise. Allegations of its flammability and ability to release harmful substances are fiction. This material can withstand temperatures up to 110 ° C and is safe for human health, which is confirmed by the conclusion of the Scientific Research Institute of Hygiene. F.F. Erisman No. 03 / PM8.
