Product Information

Warmup Coated Insulation Board

Using Warmup Insulation Boards greatly improves the energy-efficiency of an underfloor heating system. They prevent heat from passing through from the heater to the subfloor, pushing the heat produced upwards, onto the floor surface where you want it. Insulation Boards are available in a wide range of thicknesses.
