The 100mm Celotex CW4100 Cavity Wall Insulation Board is specifically designed for use in partial-fill cavity wall applications. It is a rigid polyisocyanurate (PIR) insulation solution that fits snugly between cavity wall ties. This board is suitable for new builds and extensions with a masonry cavity wall construction.

Featuring low emissivity foil facings, the Celotex CW4100 Cavity Wall Insulation Board improves thermal performance in cavity air spaces. With a thermal conductivity of just 0.022 W/mK, it is a more effective thermal cavity solution compared to rock or glass mineral wool insulation.
