SF 25

frameless all-glass system

Transparency in its most elegant form. The frameless SF 25 system does without vertical frames and then allows a wonderful view to the exterior even when it is closed. You can enjoy almost unobstructed panoramic views – and your house looks a bit more impressive, too.
