ROCKWOOL HardRock® Multi-Fix (DD) Non-combustible flat roof insulation
HardRock Multi-Fix (DD) is a BBA-approved insulation board, that in addition to thermal comfort, provides independently-tested acoustic and fire resistance properties.
Designed for warm flat roofs, ROCKWOOL HardRock Multi-Fix (DD) is a high density, non-combustible thermal insulation board which has also been tested for acoustic applications and fire resistance. ROCKWOOL HardRock Multi-Fix (DD) has been proven to improve the ability of lightweight flat roof systems to control both noise ingress and egress through the building envelope. Suitable for areas subject to pedestrian traffic and frequent maintenance, the boards are compatible with all roof covering types, including torch-on, pour-and-roll, single-ply, EPDM, liquid applied and green roofs.
