U03 - BACKER BOARD
4mm Backer Board designed specifically to provide a strong, level and extremely firm surface - ideal for tiling, can be used over Wunda's Overfloor heating boards if desired.
Providing an intermediate layer would allow the final floor finish to be removed/replaced in the future without destroying the floor heating system below.
When fitting carpets/vinyl as a final floor finish onto Overfloor heating boards we would recommend a light renovation screed or fixing a ply deck before carpeting.
Flexible and easy to handle - simply cut the board to shape where necessary. It can be dry fitted as a floating surface with taped joints or alternatively bonded directly to the floor heating panels.
Backer boards are manufactured from polyester fibres and synthetic resin.
