The Filigree line catches the eye with its minimal frame width and smooth transition of indoor and outdoor spaces. In the vertical overlap of the wings, it has a sight line of only 38 mm. In the floor, wall and roof area, the frames are flush-mounted, creating a sash sight line of only 25 mm.

There are two systems available: System I with 125 mm depth for double glazing and System II with 150 mm depth for triple glazing. With the Filigree line, a Uw value of 0.9 W/m2K can be achieved, which meets the requirements for low-energy houses. The KORN Filigree range can also withstand extreme weather conditions.

The Filigree line is mainly used in buildings with a modern architectural design.
