Product Information

PIR Cavity Wall Insulation is the most popular type of rigid insulation wall boards, comprises a fiber-free rigid polyisocyanurate (PIR) insulation core with aluminium foil composite facing on both sides. It has a high compressive strength, improved insulation & durability. Moreover, it provides improved fire resistance and moisture tolerance.

Use & Application

Due to its high-performance insulation, the PIR wall insulation board is suitable for cavity wall applications with maintaining a residual 10mm cavity. This will help the board to resist moisture transfer and aid installation.
