Our Low profile tile backer insulation boards are high quality extruded polystyrene panels, covered with a fibreglass mesh on both sides, for use with our under tile heating 150w mats. Available in 6mmand 10mm thickness. They are ideal for two purposes; as a superior waterproof surface to fix wall or floor tiles and heat insulation for underfloor heating systems.



1 board covers 0.72m2 / boards are 1200 x 600mm


When installing onto wooden floors we recommend using our insulation fixing pack or alternatively, suitable screws and washers. Screws and washers must be fixed at minimum 300mm centers. This is approx 100 fixings per 7 boards. 

When installing any type of tile backer board onto concrete sub floor, we recommend using Flexible Tile Adhesive ensuring the floor is primed with a suitable primer before installation.
