Rockwool Fire/Cavity Barrier

by Rockwool

A range of wired mineral wool mats designed to be hung from the soffit or roof construction to extend the line of a fire/compartment wall or to sub-divide extensive roof voids. A 25 mm galvanised wire mesh is stitched with wire to one face to produce a flexible fire barrier with optional foil faces.

Fix at head using the Rockwool angle support system, comprising an angle support and a clamping plate. At the base it is preferable to either wire the barrier to the ceiling grid or fix using the angle support system, although it can drape freely, turned back across the ceiling.

50 mm Fire Barrier, single and double layers, can be extended from a 3500 mm drop to a maximum 6000 mm drop by fixing an additional 2500 mm section stitched with overlapped joints. Contact Rockwool Technical Services for advice on the use of drops over 6000 mm.
