Comparing insulation materials for a roof
Choose roof insulation to suit the project. A new flat roof and a pitched roof being renovated offer different places for insulation. In a pitched roof there may be room between or below the rafters, or for a continuous layer over the structure. In a flat roof, consider the position of the insulation in the build-up and the pressure it must withstand. Compare declared thermal conductivity and mechanical properties in the context of the complete roof section. PIR boards, mineral wool, XPS and EPS each suit particular conditions.
