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.

In testing, heat-up time was cut from over 2 and a half hours to just 20 minutes. This data applies to Warmup heating products only.
