DIFFERENT INSULATING COMBINATIONS FOR THE ROOF
Insulation on the roof with a sandwich panel and uncovered belts.
Insulation for the roof with a simple sheet and an internal panel with an insulating nucleus PUR or PIR.
Insulation on the roof with a simple sheet, air chamber with a glass wool, and a simple sheet false ceiling.
Insulation for the roof with a simple sheet, air chamber with a glass wool, and a false ceiling made of a panel sheet with an insulating nucleus PUR or PIR.
Materials used for a correct insulation Polyurethane: It is an insulating synthetic material for different construction applications; its high insulating power as well as extreme lightness, makes it an ideal material as an insulating nucleus for the enclosures of the roof or perimeters. Very low thermal conductivity synthetic material; it is the lowest one considering all the insulating materials. This is important given that it allows a higher insulation degree with less thick material Polyisocyanurate: the combination of the polyol and isocyanate elements gives some very specific features to the material due to the different chemical structures. The insulating PIR sheets are used given their higher thermal stability features and resistance regarding fire. Rock wool: or glass fiber, it is a material made of volcanic rock. It is mainly used as a thermal insulator as well as passive protection device against building fire, due to its fibrous multidirectional structure, which allows storing relatively immobile air inside. The structure made of rock wool includes some dry and stable air inside, therefore it works as an obstacle to the transfer of heat, insulating against low and high temperature.
