The new generation of floor-to-ceiling aluminum windows allows for narrow face widths with the highest functionality and optimum thermal insulation. The system generates maximum transparency due to the seamless integration of vent and load-bearing structure: fixed fields and opening units are indistinguishable from the outside. On the inside a slender, flat shadow gap and the window handle betray the presence of the opening units. Two basic depths combined with the attachment to building structure for individual use allow for a wide range of easy-to-install applications: from traditional and storey-height ribbon windows to punched openings.
