Roof Insulation is the best and widely used method to prevent heat penetration from the outside environment to inside of the building. 90% of the radiations from the sun are blocked with the help of insulated roofing sheets. Roof insulation provides temperature stability and prevents unwanted noise penetration.
Insulated roofing sheets also prevent moisture condensation which may lead to mold, dripping, and rot inside your building. Thus, many architectures are incorporating special roof insulation like PUF to extra care about the design and enhance the thermal stability of the buildings.
