Designed to withstand a load of 30 tonnes per square metre, this insulating board is ideal for use with underfloor heating as it prevents the heat from penetrating down into the substrate below.Easy to cut and shape around fixtures with a knife or saw, this Warmup insulating board comes in 6mm and 10mm thicknesses to suit floor and wall applications. It can be fixed to solid or stud walls and is excellent as internal wall insulation, especially when compared to standard cement building boards and plaster boards.
