CW4000 Cavity Insulation Board – 100mm

This insulation board is aimed specifically at partial fill cavity wall applications. It comprises a polyisocyanurate rigid foam insulation core, with a thermal conductivity of 0.022 W/mK and low emissivity aluminium foil facings on both sides. CW4000 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP).
