PRESTIGE MINIMAL Keller Minimal 4+

Our extensive product range impresses with the simple beauty of minimalist design, without compromising on functionality or comfort. Our minimal windows®4+ collection, featuring triple-glazed premium windows available as sliding or fixed elements, is perfect for large glass facades, allowing for open living spaces with maximum daylight and unobstructed views of the outside. With this product, architects can transform innovative visions into luxurious living environments.

Thanks to the excellent insulation of minimal windows®4+, oversized glass surfaces with a height of up to 6 meters and a total weight of up to 1,000 kg are possible. The windows comply with the latest standards for energy-efficient buildings, making them ideal for low-energy and passive houses.

The high-quality insulation glass provides significant energy savings with a Uw value of ≥ 0.70 W/m²K. The aluminum frames also offer excellent resistance to wind loads.

The minimalist frame profiles, which can be seamlessly integrated into the floor, ceiling, or walls, have excellent thermal insulation properties. The extremely slim frame profiles allow for a viewing width of only 26 to 34 mm.

With our triple-glazed minimal windows®4+, your imagination knows no bounds. Architects, planners, and homeowners have a multitude of design options. Post-free interior or exterior corners, pivot elements, full glass corners, or rounded profiles with a curved shape – with us, you have plenty of choices. For a particularly seamless transition between indoor and outdoor spaces and unrestricted views, the sliding elements can disappear completely into specially designed wall pockets.
