minimal windows®

Window elements up to four metres high can be opened silently and also allow a clear view to the outside when closed, because neither wide posts nor other distracting frames cloud the view. KELLER’s innovative minimal windows® concept is based on slender profiles and frames and thus reflects the spirit of contemporary architecture: namely modern, open living.

KELLER minimal windows® are based on high-quality materials that meet the performance requirements over many years and turn your own living space into the dream of a lifetime.

KELLER minimal windows® is a proprietary development by KELLER in Troisvierges and was the eye-catcher at the Bau in Munich, the largest world’s largest construction industry trade fair.
The KELLER minimal windows® sliding window system can be used both for home conservatories and in new and renovated buildings. Visitors can see and test KELLER minimal windows® in the showroom in Troisvierges or at one of our numerous sales partners.
