Introducing CavityFill Unilin Insulation’s Enhanced PIR Full Fill Cavity Wall Insulation Solution

The enhanced PIR insulation redefines full-fill cavity walls. With a lambda of 0.021 W/mK and Euroclass E fire rating, it delivers passive-level performance without compromising on protection or quality.

Engineered for performance, Cavity Fill delivers a declared lambda value of 0.021 W/mK, achieving U-Values as low as 0.12 W/m²K in traditional cavity widths up to 150 mm. Its textured foil facing and engineered jointing ensure a secure fit and consistent thermal performance, while maintaining a 10 mm residual cavity for superior protection against wind-driven rain. With a Euroclass E fire classification, Cavity Fill XT/CF sets a standard for thermal efficiency in UK masonry wall construction
