Fire proof doors

The fire resistance of doors is determined on the basis of results of lab tests. These are carried out according to the NBN 713.020 “Resistance to fire of building elements” standard.

The current RF standards remain in force until July 1, 2022. From then on, the new European EI-standard is required for new construction.

In most cases, the old RF standard is still permitted for renovations, also for building applications submitted before the date of the new standard.

Core from chipboard with a density of approximately 400 kg/m², placed in a pine wood frame. Both door surfaces are covered with a hard wood fiber plate of approximately 3 mm thickness. A strip of foam-forming product is incorporated in a slot in the edge. In the event of a fire, this strip starts to turn off and the edge wood pushes against the frame, so that the crack is closed.

The Benor approval is based on the whole of the test reports.

The doors must meet the following 3 criteria:

  • Stability
  • Flame-density
  • Thermal insulation

It is recommended to have a fire-resistant door installed by a recognized installer with ISIB certificate ( This way there is sufficient certainty about the correct placement. This can be demanded by the insurance company.

  1. All parts of the door set must correspond to the data in the Benor approval.
  2. The tests concern the frame, door leaf, wall, hinges and other hardware together, and not to the parts separately.
  3. The installation must be performed as described in the Benor report, and nothing is to be changed after installation.
  4. Shortening the doors after production is not allowed because of legal reasons.
  5. Fire rated doors are also available with cnc-milled lines.
