- The coated insulation board is a water resistant, insulated tile backer board made of extruded polystyrene, faced on both sides with a fibreglass mesh embedded into a thin cement polymer mortar.
- The board is designed to withstand a load of 30 tonnes per square metre and is ideal for use with underfloor heating as it prevents the heat from penetrating down into the substrate below.
- Note: Under a floating floor, the uncoated insulating boards can be used.
