Rockwool Fire Barrier

Rockwool Fire Barrier systems offer labour-saving solutions to prevent fire and smoke spread within roof and ceiling voids for all general conditions encountered on site.

The vertically hung Fire Barriers are capable of achieving both integrity and insulation protection periods from 15 to 120 minutes and the friction fitted Fire Barrier Slab can also provide 60 minutes integrity and insulation.  It is Rockwool’s essential insulation performance that limits the heat transfer through the barriers, preventing ignition of combustible materials in adjacent areas.

The new patent applied for, support system (application no. 0329817.1) offers a quick, cost effective installation method for the Fire Barriers for periods up to 60 minutes. This focus on ease of construction and installation has the added benefit of reducing the risks of installation error. 120 minute systems are also available using the traditional support methods. Extended drops are easily catered for, with the system capable of maintaining its performance in void heights up to 10.5 metres

The FF2 Fire Barrier Slab is a Rockwool slab faced with aluminium foil on both sides, designed for fire stopping voids up to 1 m high and 20 m long.

The slabs are cut to height and friction fitted within the opening: butt joints between slabs and perimeters are sealed with Rockwool Acoustic Intumescent Sealant.
