The millimeter thin insulation from Depron®

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

What is Depron®?

Depron is a 3 or 6millimeter 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.  

Depron with Carbon Heating



An insulation capacity that saves energy

The special cell structure means that the sheet does not conduct heat. Laying Depron 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.


Effective protection against damp and cold

Depron not only takes care of the heat, it is also an effective guard against the cold and damp.
The material is resistant to cement, plaster and most alkalis, however, not against organic solvents.
Depron is water repellent – does not rot or go mouldy. In addition the sheets have a sound insulating
effect, which makes the floor "quieter" to walk on.


Increase the effect of the floor heating

The insulation sheets are easily laid between the existing floor and the floor heating foil.
This gives not only a smooth and protective underlay but also increases the effect of the floor heating.Buy Depron
