The Isover cavity wall slab 36 adds excellent thermal performance to your home’s external cavity walls. Meeting all UK thermal building regulations, this Isover CWS 36 wall slab helps prevent heat loss in your home by trapping the warm air in the insulation material and stopping air from circulating.

This Isover cavity wall slab 36 is also easy to cut, handle and install. It can be fitted as the walls go up and are sized to slot between standard-spaced wall ties. Sound transmission is minimised and the material used is highly resistant to fire and won’t allow flames to spread quickly. This size of Isover 36 Cavity Wall Slab has a coverage of 8.74m².
