    • Excellent sound insulation: impact sound is greatly reduced
    • Cuts with a knife. No need for a jigsaw
    • Will accept even the heaviest wall tiles, unlike plasterboard.(correct installation method must be followed)
    • Excellent heat insulation with thermal conductivity value of 0.027 W/mK making them ideal for use as a thermal barrier with under floor heating.

Tile Backer Board Installation

There are 2 options when it comes to subfloors; Concrete and wood. Tile backer boards can be used on both types of subfloors however they do need to be installed differently.

  • Wood Subfloor Installation

    When installing onto wooden/ply floors we recommend using a ProWarm™ insulation fixing pack or suitable screws and washers. Screws and washers must be fixed at minimum 300mm centers. This is approx 15 fixing per boards

  • Concrete Subfloor Installation

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

What are the benefits of underfloor heating?

The radiant form of underfloor heating with even heat distribution is far more comfortable and efficient than the convected heat provided by radiators, which draws cold air across the floor, heating it and then convecting it upwards towards the ceiling.

      • Even heat distribution
      • Individual room control
      • Free up wall space
      • No more cold floors
      • Energy efficient save on bills
      • No exposed pipework
      • Minimal maintenance
      • Reduced airborne dust pollution
