U04 - DUO BOARD x4 FACTSHEET
DUO BOARD is a quick, simple and dry solution to install with a very low thermal resistance allowing heat to transfer quickly and easily for a rapid response and maximum comfort. Made from HDF high-density fibreboard, which is engineered wood fibres that have been highly compressed. It is similar to MDF medium-density fibreboard but is denser and much stronger. Suitable for the immediate glue-down of all resilient floor coverings, such as LVT*, vinyl, Linoleum, cork, carpet and carpet tiles, when used in conjunction with Wunda 800g/200mu Vapour barrier & Wunda barrier tape. * Temperature sensitive floor finishes, such as LVT will require the use of a floor probe to protect your final floor finish.
The base board is laid first with adhesive side facing up then the top board is then laid brick bond fashion onto the exposed adhesive surface producing a seamless surface, preventing ‘joint lines’ from showing through carpet, vinyl and linoleum floor finishes.
When laying DUO BOARD allow an expansion joint, the expansion joint should be between 5mm to 10mm and can be filled level with the board surface using a flexible sealant/filler.
DUO BOARD is not suitable for use in bathrooms, wet rooms, en-suites or any other wet areas, the boards will expand upon contact with moisture.
DUO BOARD is not a structural sub-floor for use as replacement of floor boards/decks.
