Description

NyRock Cavity Slab 032 is manufactured from stone wool using patented technology that creates a more efficient fibre structure. This increases the density of air pockets within each slab, delivering improved thermal performance compared to standard stone wool cavity batts.

The lightweight slabs are designed for friction fitting, which helps minimise gaps during installation and allows accurate fitting against blockwork without the need for precise cutting. This approach reduces thermal bridging and improves overall cavity insulation effectiveness.

Achieved Euroclass A1 fire rating in accordance with BS EN 13501-1. Thermal conductivity is 0.032 W/mK. BBA approved (Certificate No. 22/6252).
