Rock Wool Board 100 kg/m³ High Density Load-Bearing Flat Roof
Rock Wool Board 100 kg/m³ high-density, A1, compressive strength ≥40 kPa at 10% deformation. Designed for inverted flat roof insulation, raised access floor thermal break, and industrial cold storage floor insulation systems.
// Key Features
- Compressive strength ≥40 kPa at 10% deformation qualifies for load-bearing inverted flat roof and floor applications
- Dimensional stability ≤0.1% preserves flatness of the roof insulation layer under sustained static and dynamic loads
- Class A1 non-combustible ensures fire-safe construction in inverted roof and raised access floor assemblies
- High density prevents point-load crushing deformation under foot traffic, plant, and maintenance access loading
