Type DPS, DPL and DPX thermal insulation boards



The Frinorm type DPS, DPL and DPX thermal insulation boards are suited for insertion in ceiling formwork in underground car parks, garages and basements in single and multi-family houses as well as in commercial, industrial, agricultural and public buildings.





  • Outstanding thermal insulation values of up to 0.15 W/m²K
  • Three types of thermal insulation boards: with expanded rigid polystyrene foam (EPS), expanded rigid polystyrene foam with graphite additive (EPS lambda) or extruded rigid polystyrene foam (XPS)
  • Element thicknesses of up to 200 mm can be produced
  • Cement-bonded chipboard as cover panel, water-resistant, impact-resistant and non-combustible
  • Rot-resistant, resistant to vermin and mould
  • Dimensionally stable and non-warping
  • No thermal bridges, perfect board joins
  • Washable and can be cleaned with a high-pressure cleaner
  • Appealing aesthetic bottom view
  • Handy format, lightweight
  • Uncomplicated and fast installation

The Frinorm thermal insulation boards have very good thermal insulation properties. They are available in three different designs: type DPS is made of expanded rigid polystyrene foam (EPS), 15 kg/m³, type DPL of expanded rigid polystyrene foam with graphite additive (EPS lambda), 20 kg/m³, while extruded rigid polystyrene foam (XPS), 33 kg/m³, is used with type DPX. The thermal insulation boards are covered with a 10 mm thick cement-bonded chipboard, which is not only water- and impact-resistant, but also non-combustible. The dovetail grooves in the surface of the thermal insulation ensure that the thermal insulation boards adhere to the concrete so that additional fastening material is not required. The sophisticated groove and tongue joints that prevent the formation of thermal bridges, the additional rabbet in the cement-bonded chipboard and the join cover rail inset into the thermal insulation reliably prevent cement water penetration. The join cover rail also prevents the boards from shifting in place. A 3 mm shadow join and a 1 mm bevelled edge on the cement-bonded chipboard ensure a nice bottom view. The cement grey surface can be left untreated or coated with dispersion paint.
