For homes lacking a loft or other roof space typical of a pitched roof, flat roof insulation is ideal. Insulation for flat roofs offers many advantages, including cutting heating costs and reducing how quickly rooms cool or warm up, all of which have a significant impact on your home's energy efficiency.

Flat roof insulation is installed as a layer between the ceiling of your home and the roofing membrane. There are two types of roof insulation: warm roof insulation and cold roof insulation.The most common roof insulation materials are cellulose, fibreglass, and mineral wool (the same as for pitched roofs).
