UNCOMPROMISINGLY SYMMETRICAL
Passive House Symmetrical System
ONE
ONE has brought back the sleek elegance of the windows without sacrificing today’s thermal insulation and other requirements.
ONE is also the only window and sliding door system of its kind with uncompromising symmetry.
A novel window and sliding door system with extremely slim frames that are only half as wide as ordinary windows and doors
Symmetrical on all four sides: Fixed part and openable part with the same frame width and the same glass – inside and outside. In conventional windows fixed parts and openable part are in no way symmetrical.
