STS Fibre Cement Construction Board 1200 x 800 x 12mm
Fibre Cement provides a solid and durable surface on which to tile. For years we have believed that Fibre Cement is the industry standard when it comes to tile backing and that traditional methods such as plywood or plasterboards are no longer fit for purpose. This has recently been highlighted by a change in the British Standards advising not to tile on these substrates but rather use an appropriate tile backing board.
The strength of Fibre Cement means you can have minimal build-up on floors and walls without compromising on strength or integrity of the substrate.
Suitable for internal and external use. Impervious to moisture and A1 Fire Rated. The STS Construction Boards have numerous applications including over boarding timber floors prior to tiling as well as cavity closure, eaves boards, under canopies, or as a ceiling board where fire rating is required. The A1 fire resistant board means that your structure will be safer in the event of a fire outbreak.
