Reliable and cost effective
Rockwool EnergySaver cavity wall insulation is an entirely dry system which uses granulated 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 both new and existing masonry cavity walls as well as certain types of non-traditional structures. Rockwool EnergySaver blown wool does not create a bridge or capillary path within the cavity that might allow rainwater to penetrate to the inner leaf.
Over half the energy required for heating a building escapes through the exterior walls. With approximately 75% of domestic energy consumption devoted to heating, the ecological and economic impact of this is significant.
