open frames Poland

...Folding-sliding (bi-fold doors with external opening) allow large surfaces to be simply swept to the side. The door parts fold on hinges from one side: to the outside. They are ideal for generous spaces or for conservatories and vary in large areas. The entire glass wall can be almost completely opened while the individual elements are folded and pushed to the left or right into a corner. The folding frames are exactly like the frames with external opening or like traditional sliding frame windows. The folding strips have almost identical glass beads.
