Duo Board is a free-floating HDF sub-floor specifically designed for installation over floor heating to provide a smooth, stable and level base for laying off the roll carpet, vinyl and linoleum directly onto. The DUO BOARD system comprises two layers, a baseboard with an adhesive surface and a top board both are laid in an overlap/brick bond fashion. (For Karndean and Amtico planks we would recommend a renovation screed as a subfloor and not Duo Boards) Expansion joints are required in any 8-metre direction.

Dimensions: 1200mm x 600mm x 3-4mm

Quantity: Every 2.88 sqm =  4 pairs of Duo Boards.

IMPORTANT: Before installation, the Duo Boards must be stored for a minimum of 48 hours at a temperature not lower than 18°C and relative humidity of no more than 60th in the room where the Duo Boards are to be used. 

PLEASE NOTE: You can not use tile adhesives or levelling compounds on these DUO BOARDS
