140mm Recticel Eurowall+ Full Fill Insulation T&G Board 1200mm x 460mm (4.42m2/Pack)

Recticel Eurowall+ Full Fill Insulation T&G Board measuring 140mm thick and 1200mm × 460mm in size. High-performance rigid polyisocyanurate (PIR) insulation board designed for full-fill masonry cavity wall applications. The board features a tongue and groove joint on all four sides to ensure precise interlocking, minimising thermal bridging and maintaining consistent insulation continuity across the wall cavity. Each board is faced with a multi-layer gas-diffusion-tight foil, reflective on one side and alkali-resistant on the other, optimising thermal efficiency and long-term durability within the cavity environment. The rigid PIR core delivers excellent thermal performance with a declared conductivity of 0.022 W/mK, achieving strong U-value reductions in modern wall systems.The 140mm thickness achieves exceptional thermal resistance, supporting ultra-low U-values and compliance with advanced energy standards.
