Underfloor Heating Insulation Boards

Underfloor heating insulation boards are available in two formats. We stock a high density extruded polystyrene insulation board which is for use over concrete or screeded substrates. For plywood, chipboard or timber other flexible floor bases we recommend Marmox tile backer boards to reinforce and insulate the floor before laying heat mats.
