Sliding system SF22

Height compensation

The ceiling rail adjusts to height differences up to 20 mm in case of building subsidences at the upper construction.


Maximum transparency, permanent ventilation and protection against driving rain are ensured by a 24 mm covering of the panels when closed.

Barrier free living

Optionally a flat bottom rail (height = 13 mm) is available which is particularly suitable for indoond “barrier-free dwelling” in compliance with DIN 18025 - whether mounted or recessed into the floor.

Vertical frames

Increased driving rain and wind resistance by vertical frame profiles with brush gaskets, available as option.

Locking mechanism

Optionally an handle, a lock and a locking mechanism can be fitted to the panel internally and externally.


On closing and opening the sliding door each adjacent panel respectively is automatically moved by the integrated followers.

Drainage and cleaning

A sloping floor construction and optimally shortened rail lengths permit unpressurised drainage and simple cleaning of the floor rail. The anti-slip coating ensures that the floor rail surface is safe to walk on.

Height adjustment

To compensate for structural variations the integrated rollers can be adjusted for height by up to 5 mm.
