Product Details

Product Details

Tile backer boards are used under wall or floor tiles to act as a waterproof surface and to provide efficient insulation. When used as part of a flooring solution, they also help to dampen sounds.

These items can be used in conjunction with our underfloor heating systems by being installed onto concrete, screed and timbers subfloors. This way, you will be maximising the efficiency of your heating system and reducing heat loss.

Available in various thicknesses (6mm, 10mm, 12.5mm, 20mm, 30mm and 50mm), these boards are sized at 1,200mm x 600mm and cover an area of 0.72m². More durable and rigid than plywood, tile backers are waterproof, making them ideal for installation in any wet areas.

The boards are lightweight and easy to install. When fitted over concrete floors, they can be secured in position using flexible tile adhesive, while screws work for wooden fixtures.



Concrete Subfloors

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.

Wood subfloors

When installing onto wooden 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.
