Continuous Fixed Glass Facades
Keller minimal windows® highline solutions combine ultra-slim aluminum profiles with fixed glass elements for large, aesthetically appealing glass-only facades. Sweeping views are entirely unobstructed, due to massive fixed glass elements, up to 18m² in dimension.
Frameless glass facades accentuate the unequivocal minimalism of contemporary residential and commercial architecture. The flush-mounted fixed glass elements can be installed as a stand-alone fixed system, or effortlessly combined with our minimal windows® double-glazed and triple-glazed sliding elements.
The minimal windows® highline series has three options for distinctive structural design, to cover various structural stability requirements. Glass-to-glass, semi-structural-glazed and cover-cap look.

The glass-to-glass variant guarantees entirely unobstructed views, with a maximum dimension 12 m². The fixed elements are bonded directly, without structural aluminum profiles. The only visible element is the 10 mm butt joint of the structural glaze (SG) join.

The semi-structural-glazed (SG) variant is more stable, due to its 22 mm aluminum static interior profile. An expansive surface dimension of a maximum of 18 m² is possible. The exterior still has a glass-to-glass facade. UV-resistant silicone adhesives fix the insulated profile to the bonded glass panes. The only visible element is the structural glazed (SG) 20 mm butt joint, from the exterior.

Our classic cover-cap look features extended stability via a 22mm aluminum static profile on the inside and a 22 mm cover-cap profile on the outside*, which allows for a maximum glass leaf surface of 18 m². UV-resistant silicone adhesives fix the insulated profile to the bonded glass panes. Fixed glass elements can be configured together with sliding glass elements, ensuring a seamless appearance via the exterior cover-cap profile.
