Cavity wall installation

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 nontraditional 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.

Features & benefits

• Ensures a complete fill without settlement
• Water repellent – will not allow water to migrate across cavity
• Vapour permeable – allows construction to breathe, reducing condensation risk
• Cost effective solution for new build and refurbishment
