The product normally consists of a 20mm facing of natural cork autohesively bonded to a closed cell polyurethane foam core and is totally compatible with all fully bonded built-up roofing systems and mastic asphalt.
The use of cork also means that no venting layer - 3G type felt - is required during installation of felt weatherproof systems.
The underside of the board has a bitumen roller-coated glass fibre tissue which, like the cork is autohesively bonded to prevent failures at the glue line.
Cork composite can be used on most types of decking.
