The 150mm Celotex XR4150 PIR Insulation Board is a high-performance thermal insulation board with composite foil facings. It is designed to provide excellent thermal performance and reduce heat loss in various applications such as roofs, floors, walls, and timber joists.

It is made from expanded Polyisocyanurate (PIR) insulation foam with foil facings on both sides. The board uses a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). With a low thermal conductivity of 0.022 W/m.K, it provides exceptional thermal performance, preventing heat loss with minimal thickness. It meets the current and future requirements of Building Regulations and is certified by the BBA for use in various applications.
