ROCKWOOL Steel Frame Slab delivers performance to meet and exceed thermal building regulations for external walls in steel frame buildings. Being made from stone wool means the highest Euroclass A1 non-combustible reaction to fire rating, as well as exceptional sound absorption properties.

The Steel Frame Slab delivers thermal performance at an optimal weight and features dimensions tailored for light gauge steel frame walls. The slab can significantly reduce outside sources of noise when used in an external wall. ROCKWOOL stone wool repels liquid water due to its fibre orientation and a water-repellent additive.

Features and benefits:
