This PIR insulation board measures 1200 x 450 x 50mm and is designed for partial fill cavity wall applications in traditional masonry construction. It features square edges and a low emissivity foil facing, supporting practical installation while maintaining the required residual cavity.
Typically fitted between inner and outer masonry leaves, the board assists in reducing thermal bridging, particularly when combined with corner panels and cavity closers. The residual cavity remains unobstructed, helping to protect the building from wind-driven rain during and after installation.
