HeatThat™ Insulation Boards

HeatThat™ Insulation Boards are manufactured using a high-density extruded polystyrene core with a polymer modified, glass fibre reinforced cement coating on both sides, which adds rigidity and strength. Using HeatThat™ Insulation Boards and the range of accessories quickly creates an ideal, stable substrate for thin/thick bed tile adhesive and underfloor heating.

Timber Floors

When fixing tiles onto a timber floor it will generally need strengthening. This can be done using a minimum thickness of 10mm HeatThat™ Insulation Boards, which must be fixed with a flexible cement-based tile adhesive.

Ensure that all floorboards are screwed down thoroughly at 300mm centres before fixing HeatThat™ Insulation Boards with fixing screws and washers. Ideally lay the HeatThat™ Insulation Boards across the floorboards at 90° for maximum stability.

Concrete Floors

Before fixing HeatThat™ Insulation Boards to any floor make sure it is free from dust or any loose materials. If your adhesive manufacturer recommends it, treat the floor with a suitable primer to ensure good adhesion.

Solid concrete floors transfer the cold and damp from below so HeatThat™ Insulation Boards should be used before tiling for its excellent thermal properties. It is particularly beneficial when installing underfloor heating onto a concrete substrate.

Underfloor Heating

When underfloor heating is being installed, 12mm HeatThat™ Insulation Boards is recommended as a minimum thickness for its superior thermal properties.

The thermal properties of HeatThat™ Insulation Boards minimise the amount of heat lost through the substrate making your underfloor heating system up to 50% more efficient and cheaper to run.
