Keller Minimal Windows Highline® is innovative premium glass facade system combines aesthetics with outstanding performance features. The slender and frameless glass facades enhance the pure minimalism of current architecture. The glass facade between two structural floors comprises thermally insulated, concealed aluminum frame profiles and is ideal wherever minimum facing width and maximum glazing height is desired. The flush-mounted or symmetrically alternating offset planes of the glass facade can be combined with ultra-slender design sliding doors to give the perfect solution for high-rise residential projects and business premises. Available as double- or triple glazing versions. Stability of the sliding system tested under extreme wind loads with a nominal load of 2,000 Pa (approx. 200 km/h) and a peak load of 3,000 Pa (approx. 250 km/h; with brief gusts of wind) in accordance with EN12210 and the classification C4/B5.
