HARDROCK® Multi-Fix (DD)

HARDROCK® Multi-fix Recovery Board is manufactured with a coated fibre glass fleece, which when used for adhered membranes, forms a secure bond between the membrane and roof insulation, limiting the amount of adhesive and other ancillaries required.

Suitable for both domestic and commercial refurbishment, the board can be installed directly over the in-situ roof membrane, easily handling any minor imperfections on the existing external finish.

HARDROCK® Multi-Fix Recovery Boards are non-combustible and can be used to enhance the acoustic performance of the roof.

Features and benefits:

• Can be installed directly over the in-situ roof membrane.

• Will accommodate minor imperfections on the existing external finish.

• Can be adhesively applied or mechanically fixed.

• Excellent heat resistance, ideal for torch applied bitumen systems.

• A single solution that is compatible with most roof coverings.

• Reduces external noise ingress.

• CE marked.

Acoustic performance

When tested in accordance with BS EN ISO 10140-2:2010 as an individual 30 mm layer within a single ply flat roof system, onto a 0.7 mm profiled steel deck, the system performance achieved Rw 33 dB.
