Lift and slide door
Lift and slide doors are glazed balcony or balcony doors made of wood , plastic , light metal or combinations of these. Compared to a wing door, these allow considerably larger passage openings, thereby ensuring significantly better ventilation and offering the possibility of large-area glazing. Large window fronts in particular can be designed attractively by arranging several wings. Even if it is a sliding door , it can have a very high degree of tightness .

When the sliding sash is closed, the front and rear seals engage in predetermined profiles, when the sliding sash is lowered it presses into its seals at the bottom and the seals at the top press against the guide rail.
