Thermal Substrate Boards
light weight, structural boards ready for tiling
For further information or quotation
GOSS thermal substrate boards are constructed from an extruded polystyrene core coated on both sides by a highly polymer modified cement like coating. Encapsulated within the coating is an alkaline resistant glass fibre reinforcing mesh.
The foam core ensures outstanding thermal insulation properties and high compressive strength with very low weight. The cement based coating gives the product exceptional impact strength and resistance. The cement coating also improves the fire resistant qualities of the board and creates a tile ready face.
Our boards are manufactured in a variety of thicknesses, from 6mm to 70mm, and in areas from 1200mm x 600mm to 2400mm x 1200mm. They are used in large quantities to insulate underneath electrical underfloor heating and as waterproof wall boards in wetroom, steamroom or damp environments.
Being light weight, structural boards which are easy to cut and shape, GOSS Thermal Substrate Boards can be used to create all manner of complex structures.
