A barrier-free building must meet various requirements in the area of doors, windows, thresholds and flooring.
Doors should be easy to recognise, open, close and pass. Sufficient contrasts and the avoidance of reflections must be ensured. Windows should be easy to open and close from a standing or sitting position. Alternatively, operating aids for doors, windows and curtains can be installed.
Ramps are used to bridge thresholds. These can be permanently installed or mobile.
The floor coverings should be level, non-slip, easy to walk on or drive on and not be electrostatically chargeable.
