The Celotex CW4040 Cavity Wall is a fantastic thermal insulation product designed to partially fill insulation for masonry cavity walls. This rigid polyisocyanurate (PIR) insulation board fits between cavity wall ties, insulating the air spaces in the cavity. It’s perfect both for new and existing builds, as well as project extensions.

This Celotex Cavity Wall insulation consists of a polyisocyanurate rigid foam and an insulation core. Having a thermal conductivity that comes out to be 0.022 W/mK, Celotex offers the ability to achieve desired U-values for the walls of the building without any problems.

This CW4040 Cavity Wall insulation is a smart solution offering long-lasting and substantial energy savings for all types of construction projects and buildings. There are aluminium foil facings with low emissivity on both faces to provide better strength and superior dimensional stability. The clips offer extra retention to the material. These unique features make this PIR Celotex Cavity Wall insulation one of the best-performing insulation materials available on the market.

The Celotex CW4040 is formed by combining blowing agents that contribute to low global warming potential (GWP) and zero ozone depletion potential (ODP).
