HARDROCK® Multi-Fix Recovery Board
HARDROCK® Multi-Fix Recovery Board provides a non-combustible level surface suitable for receiving all commonly used flat roof membranes, including single-ply, EPDM, bitumen and liquid-applied systems.
The product is manufactured with a mineral-coated glass fibre tissue, 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.
Ideal 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.
