Sliding and Folding

In the folding-sliding systems the “folding mechanism” practically allows you to open the entire opening width.

  • The sash elements can be folded differently depending on the design version.
  • No fixed glazed elements, sides or jambs block the opening.
  • GERMAN made SIEGENIA hardware allows sash weight up to 80 kg.
  • Three sealing levels ensuring maximum air and water tightness.
  • All sash's and frames overlapping each other.
