80mm Unilin Xtroliner XO/CW Partial Fill Cavity Wall Board

Discover the 80mm Unilin Xtroliner XO/CW Partial Fill Cavity Wall Insulation Board, an innovative wall insulation solution featuring robust facings, carefully engineered jointing systems, sharp corner details, and an impressive lambda value of 0.021 W/mK.

This low lambda rating substantially improves thermal performance and meets Future Homes requirements, making it perfect for energy-efficient and passive house projects. Using 80mm Xtroliner XO/CW Partial Fill Insulation, you can achieve an excellent passive U-Value of 0.15 W/m2K in a standard cavity wall. The XO/CW (T&G) profile preserves a residual cavity during installation, offering superior protection from wind-driven rain exposure.
