ROCKFALL® has been specially designed as an over rafter mineral wool insulation system for warm pitched roofs and habitable lofts. The system is made up of HARDROCK® Multi-Fix (DD) Overlay Boards that are mechanically fixed over the rafters, ROCKWOOL FLEXI® is then fitted between the rafters.
The build-up of ROCKWOOL mineral wool insulation provides excellent thermal performance to keep homes cool in summer and warm in winter. The insulation is also effective for acoustic and fire performance, reducing the level of noise entering buildings through the roof and acting as a barrier should a fire break out. ROCKFALL® helps to create safe and comfortable environments, in the home or in the work place.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Rockwool Group is consulted before specifying.
