6mm Tile Backer Board – Electric Underfloor Heating Insulation

The 6mm Tile Backer Board is a strong, lightweight insulated tile backer board specially developed for use with undertile heating systems. It offers excellent thermal insulation performance while providing a durable, stable base for tile and stone floor finishes.

Constructed from an extruded polystyrene core covered on both sides by a glass fibre mesh embedded in a cementitious coating, this board delivers exceptional compressive strength, moisture resistance, and stability. It is designed to prevent downward heat loss and speed up heat-up times, reducing running costs of underfloor heating systems.
