The bifold doors open up rooms in a particularly elegant and efficient way. All doors conveniently slide and fold to the side, opening up the width of each room. This enables you to bring the “outside in” with spacious access to the deck or the conservatory; and to open up whole rooms for conferences, visitors or business purposes.

An additional optional safety feature is the comfort threshold which ensures that there are no chances of stumbling or slipping. This is particularly important for restaurants, retirement homes or homes for the disabled.

Of course, optimal room ventilation has been thought of: an integral tilt and turn sash that can be operated independently of the folding sashes, makes this possible.

A lock can be fitted to every bifold door for external access. The track runs on the inside to prevent dirt and leaves entering the track.

The sashes are stacked on the inside of the room and because of this fact they don’t need stays to protect from the wind.

Bifold doors in the comfort sill system open outwards and can be supplied in a width up to 7500mm. The hinges on the sashes and frame are adjustable.
