WARMUP® 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. As a wall tile backer board, tiles can be fixed directly onto the surface without prior preparation and, being totally waterproof, is suitable for bathrooms or showers.
