Although thermal insulation slabs provide a fairly decent list of advantages, but they require respect, accuracy and careful attitude. Firstly, when installing thermal insulation of any type, whether mineral wool slabs, or polystyrene, but air humidity should not exceed 80 percent. That is, the installation should take place in dry and warm weather. By the way, about warmth, it would be advisable to install plates at air temperature more than 10 degrees Celsius. By the way, the design of the heat point is carried out by professionals.
If the installation took the foundation of warm winter, then you need to remember the focused plates, and if the weather forecast promises a cooling in the near future than 5 degrees, then you need to wait with the installation. Note, high temperature also does not help improve the quality of thermal insulation, even vice versa. If it was decided to install polystyrene plates, then you need to remember that it is impossible to store them in the open sun, especially more than 2 weeks, otherwise you risk losing good insulation. The plates are placed on a special plaster, after which they should be under the protection of the curtains for about 2 days, and when they are already completely, tightly attached, it can already be worried about anything.
