ThermaSheet Insulated Building Board - 1200mm x 600mm x 6mm (Box of 6)

RRP $205 ($186.36 ex. GST)


The specially manufactured cement polymer coated board gives the ideal surface to lay your tiles directly.

It should be used especially in wet areas such as bathrooms and kitchens where walls and floors are particularly exposed to moisture. ThermaSheet is easy to use and can be fixed using cement based flexible tile adhesive – solvent based or ready mixed adhesives MUST NOT be used. Alternatively ThermaSheet can be fixed using screws and washers. Once fixed, ThermaSheet provides a perfect surface on which to apply decorative finishes such as tiles, synthetic renders, decorative plaster etc.


Without insulation, up to 40% of heat generated by an underfloor heating system could be lost through the sub-floor.
