As a material, polyisocyanurate (PIR) is one of the most efficient and cost-effective insulation board materials you can get. PIR is a significant improvement on alterative PUR insulation boards and is manufactured as a foam that is used as rigid thermal roof insulation.
Some manufactures calculate PIR insulation board to be up to 80 times more efficient than other options, making it a popular flat roof insulation and cavity wall insulation.
The most specified PIR insulation board is made from a rigid PIR insulation core that is sandwiched between two high performance aluminium foil facings. There are quite a few products to choose from, available in a wide variety of sizes and specifications. Please speak with us today and we’ll be more than happy to help.
