Parallel retract & slide doors differ from lift & slide systems...
- Because they form an all-round closed sash and frame system.
- Because the movable sliding sash is parallel to the fixed sash when closed
- Because they do not offer accessible passage
- Because the sash can be retracted evenly and parallel circumferentially from the frame for ventilation purposes.
- Because the handle has three functions: Unlock/lock, slide, parallel retract.
The advantages:
- Lots of light through large glass surfaces
- Excellent value for money.
- High insulation values
- Double sealing rails

Comfortable operation without effort, assisted by gas pressure damper : Opens by moving handle lever into horizontal position. Casement automatically moves away from frame and can be slid open.

Moving the handle lever farther toward upright position moves casement away from frame with a 6 mm parallel gap. This casement position is perfect for room ventilation

Moving the handle lever back toward downward position pulls the casement efortlessly back into the frame. The casement is fully locked when the lever is in downward position.
