About

A flat roof insulation system typically consists of an insulating material, a vapour barrier, a thermal break and a weatherproofing membrane. The insulating material is usually a foam, such as expanded polystyrene, that is sandwiched between the vapour barrier and the thermal break. The vapour barrier prevents moisture from passing through the insulation and into the building envelope. The thermal break prevents heat from passing through the insulation and into the building envelope.
