50mm Recticel Eurowall PIR Cavity Board 1200mm x 450mm

The 50mm Recticel Eurowall PIR Cavity Board 1200mm x 450mm is a specialist cavity wall insulation board manufactured from rigid polyisocyanurate (PIR) foam designed for use in partial-fill masonry cavity wall applications. Its precision-cut straight edges help minimise gaps between boards when installed, improving overall insulation performance within the wall cavity. The board features low emissivity foil facings that enhance thermal resistance and limit moisture absorption, while its robust core offers long-term durability and energy-saving benefits when correctly integrated with wall tie systems and cavity wall construction. This PIR insulation board is suitable for both new build and refurbishment projects requiring reliable cavity wall thermal performance.
