Before doing house insulation, it is necessary to choose the right insulation directly. To date, the most common are polystyrene, mineral wool and polystyrene foam. All these materials have their own positive and negative qualities. For example, the foam will crumble, and damage it is quite simple. Therefore, it must be covered on top with plaster or siding. But there is a plus, this is an inexpensive material. Mineral wool can present inconvenience in the process of installation, but at the same time it is very good during operation.
