Depron is a highly efficient extruded polystyrene insulation material suitable for use below wood, laminate or even carpets.

Also perfect for the Model maker, looking for a lightweight strond material that is easy to work with and inexpensive.

White Depron is available in 2mm, 3mm or 6mm sheets.
Grey is only available in 3mm or 6mm sheets.


Depron is a millimetre thin insulation sheet manufactured of fully recycled material, free from freon and halogen. The sheet is produced of foamed polystyrene, a material that does not age. The cell structure in the sheet is built up of fine, closed cells that give it its excellent physical and mechanical characteristics.

An insulation capacity that saves energy
The special cell structure means that the sheet does not conduct heat. Laying Depron with Underfloor Heating on the floor means that heat will instead, be effectively reflected back towards the floor surface. As "waste heat" is taken care of, you utilise energy in an effective manner and thereby lower your energy consumption.
