Cosytherm is an injected blown mineral fibre insulation material that can be used in both new constructions and existing builds.

The material is blown into cavity walls to a set density. This ensures high thermal performance. The material does not make use of glues or catalysts and is generally used when cavity cannot be treated with polystyrene beads.

Our installation crews are able to install Walltherm in specialist cases and the material is subject to a 25 year guarantee from the Cavity Insulation Guarantee Agency.
