The No More Ply Tongue & Groove Board is a 22mm version of the standard No More Ply Tile Backer Board. It is a fibre cement board that is designed to directly replace floorboards on joists.
No More Ply Tongue & Groove Board is available in two sizes: 2400mm x 500mm x 22mm and 1200mm x 500mm x 22mm.
Being constructed from fibre cement has a number of advantages that make No More Ply Tongue & Groove Board a far superior alternative to plywood floorboards. The main advantage is that they are inert, and not subject to deformation due to atmospheric conditions or water. They are extremely dense and stable, waterproof and have A1 rated fire resistance. They can also be tiled directly onto, without the need to overboard first. They are suitable for interior and exterior use.
No More Ply Tongue & Groove Board is robust and with tongue & groove edge connections, once fixed properly there is no risk of movement and they are less likely to generate squeaking or other noises. We recommend running a bead of Megastrength Adhesive along the tongue of each board, as well as on top of each joist when fitting the boards together, along with 50mm No More Ply Screws to securely fix the boards to the joists. Use 2-3 screws per joist across the short width of the board.
The boards can be easily cut to size using a PCD saw blade (poly crystalline diamond blade).
