Sandwich type panels, which are polystyrene, have a low weight and therefore do not create a large load on the construction of the building, as well as its foundation. Polystyrene is not toxic, has a low cost, as well as good thermal insulation, which will allow the use of such sandwich panels for different regions with moderate climate. Polystyrene insulation is not afraid of constant temperature changes and does not absorb moisture. The main disadvantages of such material include, slight durability in relation to other insulation materials, as well as combustibility. Roofing sandwich panels with polystyrene isolation are often used to build roofs of block structures, insulation of buildings that already exist, production facilities, etc. D.
