KELLER minimal windows®

The border between indoors and outdoors dissolves with this new ultra-slim profile system. The filigree width of the aluminium profiles emphasizes the minimalistic design that allows seamless integration into floor, ceiling and walls.

A glass proportion of up to 98% guarantees unhindered light flow only interrupted by slender 21mm (0.83”) or 26 (1.02”) / 34mm (1.33”) panel profiles. Up to four-track sliding systems in combination with fixed panels, interior or exterior corners with no distracting posts, large, telescopic-like opening variants are possible.

Keller minimal windows® is a virtually frameless, easy-action sliding window system with a minimalistic face width of the vertical central profiles of just 21 mm (0.83”). The system features double insulation glazing in thermal separated aluminium frame profiles and impresses in terms of design variants and enables convenient and easy opening and closing of the large sliding panels.
