Rockwool Cavity Batt insulation is designed to provide exceptional thermal performance, fire resistance, and moisture control for masonry cavity walls. Made from non-combustible stone wool (Euroclass A1 rated), it enhances building safety while improving energy efficiency by reducing heat loss.
Rockwool Full Fill Cavity Batt is designed to completely fill the cavity, eliminating air gaps and thermal bridging for maximum insulation performance. It is water-repellent, preventing moisture ingress while allowing the wall to breathe, reducing the risk of condensation.
For projects requiring a partial fill solution, Rockwool High-Performance Partial Fill Cavity Batt offers enhanced thermal conductivity (as low as 0.034 W/mK), providing excellent insulation while maintaining a residual air gap for moisture drainage.
Both solutions are durable, easy to install, and suitable for new builds and refurbishments, ensuring long-term thermal efficiency and fire protection. Explore our range today to find the right Rockwool Cavity Batt insulation for your project.
