ThermaSheet Insulation Board

The Radiant ThermaSheet is a specially manufactured cement polymer-coated board that is suitable for construction projects and underfloor heating insulation. It can be used to construct simple structures such as washstands, shower enclosures, bath panels, steam rooms, and spa structures without additional supporting timber framework. ThermaSheet's extruded polystyrene insulation minimises heat transfer, reducing heating costs and achieving warm floors within 20 minutes(in conjunction with underfloor heating). High thermal insulation can be achieved using 20mm boards butted closely together.

ThermaSheet is also environmentally friendly, as it is free from CFCs (chlorofluorocarbons) and HCFCs (hydrochlorofluorocarbons). These compounds are known to deplete the ozone layer and contribute to global warming. By choosing ThermaSheet, you are making a responsible choice for the environment.

The boards offer perfect surface for decorative finishes like tiles, synthetic renders, and plaster. They can be installed using cement-based flexible tile adhesive or screws and washers.

DO NOT USE solvent based or ready mixed adhesives.

Note: ThermaSheets are not designed to heat a space or room on their own, underfloor heating system is required. The boards must go below the heating elements otherwise they will block the heat.
