Frameless

KELLER AG’s minimal windows® frameless design sliding windows captivate by their slender profile geometry and flush-fitted installation to floor, ceiling and walls. The minimalistic design of the large fixed and sliding windows creates large, light-flooded living spaces.

Barrier-free

The sliding rail integrated in the floor provides for a transition without a threshold. The level installation makes for a seamless transition from indoors to outdoors. Glass walls from the floor to the ceiling can be comfortably opened and closed.

Individual

The modular premium system offers individual design freedom to architects, planners and owners. Unlimited combinations of sliding, pivoting and fixed leaf elements are possible, as are solutions without corner posts and sliding elements into wall pockets.
