Users are often baffled by the diversity of the range of insulating materials and even more so when it comes to understanding the information about them.
Before choosing an insulation product, it is important to ensure its thermal performance, expressed by its thermal resistance R and the lambda thermal conductivity factor. The application on which the insulation is to be used (roof, floor, walls, patio, etc.) will also condition its fire resistance, water behavior or mechanical stability. Other criteria, such as the environmental impact can also come into play.
