Foil faced ROCKWOOL® slab for fire stopping voids up to 1 m high.
ROCKWOOL Fire Barrier Slab is an aluminium foil faced slab used to close voids of up to 1m in height and 20m in length supported by a masonry wall (minimum density of 400 kg/m3) offering the same fire performance.
The slabs are cut to height and friction fitted within the opening. ROCKWOOL Acoustic Intumescent Sealant or ROCKWOOL LUL Intumescent Sealant is applied to the butt joints and perimeter of the barriers.
Rockwool insulation products do not contain blowing agents with an ozone depletion potential (ODP) or global warming potential (GWP), are CFC-HCFC-HFC free and 97% recyclable. They will not react with metal components or cause loss of plasticiser from PVC cables and pipes.
