"Do not use in case of fire" - this reference in elevators is common. Nevertheless the regulations of fire protection have to be applied in elevators of all buildings. Desires for modern Design, comfort and flexibility face these legal requirements.

With the application of WDS® highly efficient systems in elevator doors can be realized. These are characterized as following:

  • high fire protection classes
  • thin wall thickness
  • low weight

If time is an extremely important factor for the rescue of human life, an effective fire protection with thinnest wall thicknesses can only be achieved with microporous heat-insulating material. Our WDS® Ultra is inorganic, not combustible, fulfills the requirements according to DIN EN 13501 class A1 (behaviour in case of fire), according to DIN EN 1182 (non-combustibleness), according to DIN EN ISO 1716 (heat of combustion), and according IMO FTPC part of 1.

Also in wall construction of nuclear power plants and ships as well as in the plant construction WDS® Ultra is a safe material for highest requirements in the fire protection.
