Under Tile Insulation Boards

Insulating Boards

Insulation boards are one of those things you won't see once the floor is finished, but you'll notice the difference. Laid under your heating, they stop the warmth escaping down into the subfloor, so your floor heats up much more quickly, and on a concrete base that can mean around 30 minutes to an hour, against two to eight hours without them. The boards have a cement-coated surface that's ready for tile adhesive straight away, and because they're water-resistant, Warmup and wedi boards can also be used on bathroom and wet room walls as tile backer boards, as long as the joints are sealed.

The boards come in a range of thicknesses to suit your project, and they can go down over concrete or timber floors, with the joints taped once they're in place. Our guide to fitting insulation boards walks you through how to lay them on each type of floor, and once they're down, you're ready to lay your under-tile heating on top.
