Cosyhomes cavity wall system is a dry fill system using Granulated Rockwool blown into an external wall cavity through drilled holes to a predetermined density (40kg/m3). The system may be used to improve the thermal insulation of new or existing masonry cavity walls as well as some types of non-traditional structures.

The cavity is normally filled through the outer leaf of the wall but in some cases in new buildings this can be done through the internal leaf prior to plastering.

The Rockwool does not create a bridge or capillary path between the cavity and won’t allow rain water to penetrate the inner leaf.
