Thermal insulation

There are also several types of roof insulation. In heavy roofs, high-capacity Extrusion Polystyrene plates are normally used as thermal insulation, the degree of insulation will be higher or not, depending on the thickness chosen. In traditional DECK type light roofs, P.I.R. similar to extruded polystyrene and rock wool, the latter also has properties as an acoustic insulator. On the other hand, Slabs with Filtron type insulation are used, the plate in this case is always made of Extrusion Polystyrene.
