This rigid cavity board is built for use in traditional masonry wall constructions, featuring a polyisocyanurate (PIR) core with foil facings and an engineered HIPS outer skin. Sized at 1200 x 450 x 100mm, it is designed to provide complete fill for cavity walls during new builds or refurbishment.
The board is suitable for insulation tasks where full fill is required, and can help reduce thermal bridging when correctly installed. Its engineered joint detail supports precise installation in cavity wall projects on site.
