What Is XtraTherm CavityTherm? 

XtraTherm CavityTherm is an advanced PIR insulation board designed for full-fill cavity wall applications. 

The product’s unique engineered profile ensures that any moisture that might penetrate the external wall is directed downwards and away from the cavity, offering superior protection, especially against wind-driven rain. This safeguards your walls against potential dampness or structural harm.

The board's specialised rebated edge detailing also ensures the system fits perfectly, providing excellent thermal bridging detailing.
