Exterdens®

Exterdens® foams with an inflation pressure of up to 10 bar at 200°C and forms a microporous heat-insulating foam in the event of fire.

With the aid of graphite technology and the resulting inflation pressure, Exterdens® can also be used in a concealed manner, for example under veneer, and also in areas exposed to moisture. In the event of fire, the foam expands three-dimensionally and achieves foaming factors of up to 25 of its original volume, thus insulating and sealing joints and cavities against the flashover of fire and smoke.

Advantages of Exterdens®

  • Effective extension of the fire resistance of building components
  • Can be used in areas exposed to moisture
  • Low response temperature from as low as 150°C
  • Excellent protection due to the heat-insulating properties of the compact foam
  • The three-dimensional foaming and the high foam factor enable the filling of large joints and cavities
  • Due to the low panel thickness, expensive (door) materials or complex (door) constructions are not required

Exterdens® application range

Exterdens® is designed for use in exterior areas and in areas with increased exposure to moisture.

Exterdens® is used almost in all outdoor areas where passive fire protection is required. Exterdens® is used, among other things, in:

  • Fire doors and gates
  • Windows/ glazing
  • Partition walls, ceilings and floors
  • Safety cabinets and safes
  • Ventilation systems
  • Elevator systems
  • Pipe and cable penetration seals
  • Installation shafts and cable ducts
  • Curtain walls
  • Wooden constructions
  • and much more
