Unilin 150mm External Corner Cavity Insulation | 1200x450 | Bale

Xtratherm cavitytherm wall insulation board is a high performance composite board of pir core with a lambda value of 0.021 W/mk. The boards have gas tight facings with one face bonded to a profiled hips skin during manufacture to provide a drainage plane. Cavitytherm's unique profiled facing directs any moisture that might have penetrated the external wall down the protective facing and back onto the
external leaf. The board includes specifically designed rebated edge detailing on all four edges to allow the system to tightly interlock when installed. These preformed corner panels are recommended to ensure accuracy is achieved at this crucial junction.
