Slide and Turn Systems


Also known as: balcony glazing system, windows terraces, garden windows.

Slide and Turn Systems (SF25/SF30/SF35)

NGT slide and turn systems enhance the attractiveness of every home through the contrast of glass and wall. Their individually moveable, unconnected glass panels can be opened over the entire front and parked as a narrow stack on the side so that a hassle-free passage from the inside to the outside is ensured and the visual appearance is not impaired. When the panels are opened, they only require little space.


Double glazing of 18 mm or 20 mm is possible.
