Injected blown mineral fibre cavity wall insulation

For use in existing dwellings and new build constructions.

Cosytherm Rockwool cavity wall insulation is an entirely dry system which uses granulated Cosytherm Rockwool blown into an external wall cavity to a predetermined density. 

No glues or catalysts are involved in the installation procedure. The system may be used to improve the thermal insulation of new or existing masonry cavity walls as well as certain types of non-traditional structures.

Cosytherm Rockwool cavity wall insulation is normally installed in existing properties by drilling and filling via the outer leaf of the cavity wall. In new buildings, installation may be carried out either from outside, or through the inner leaf of the cavity wall, prior to plastering.

Cosytherm Rockwool blown wool does not create a bridge or capillary path within the cavity which therefore prevents rainwater from penetrating to the inner leaf.

Cosytherm Rockwool is not only the title and description of the material, it is a complete system developed and proven in use for over 60 years.
