Open Living Concepts for Maximum Natural Light
Our double-glazed minimal windows® system is a virtually frameless, easy-to-operate aluminum sliding window system, with a greatly-reduced 21 mm leaf profile. The oversized sliding sections, up to 4 m in height, are set in virtually invisible frame profiles, allowing you to enjoy unobstructed views. Elevate your spirit with breath-taking sea views, twinkling city nightscapes, or natural landscapes and gardens.
Inviting the exterior into your living space, by using materials reduced to their bare essentials, is at the core of cutting-edge contemporary architecture! Clean lines, balanced proportions, drenched in the all-important and crucial central element, natural light. Whether it’s a luxury villa, a detached home, an apartment, or a business complex, unobstructed views with sweeping, open interiors allowing maximum natural light to illuminate the interior, are highly valued in current architectural design. Large glass fronts that adapt seamlessly to any environment, are flush with floor and ceiling. The sliding units operate with minimum resistance, made possible by the concealed tracks integrated into the floor, technology which took 15 years to perfect.
The virtually invisible fronts of the aluminum profiles emphasize the minimalistic design of Keller minimal windows®. The limitless system configurations and design options offer optimal practical flexibility, so you can select numerous options. Glass-to-glass interior and exterior corners, open corners, pivot elements, and wall-inlets (pockets in the brickwork) that conceal sliding elements. Select from a wide variety of colors, with an assortment of textured surfaces, from matt, to polished, to powder-coated.
The frame profile is minimized to allow seamless integration into floors, ceilings and walls. Outer frames are almost completely integrated into walls, so oversized glass dimensions create wide, open living spaces. Maximum natural light infuses your interiors, creating a tranquil, elevated ambiance. Leaf sections can be as high as 4 m, with a total weight of up to 500kg. It allows us to create exceptional and expansive living environments, with sections installed on 1,2,3, or 4 tracks. We are proud to be able to fulfil the most extreme and ambitious architectural designs.
Choosing Keller minimal windows® means choosing the best possible quality. Our system’s insulation values are excellent. They maintain interior temperatures, delivering optimal conditions throughout the year. Polyamide bars integrated into the outer frame, guarantees thermal separation, which reduces energy consumption, saving on costs. In hot climates, cool air-conditioned air remains inside. Heat penetration can easily be prevented via the integration of foil which is impermeable to sunlight.
Barely perceptible exterior frames, seamlessly integrated into the floor via a fitted sliding rail, ensure smooth, unobstructed transitions. High-performance tracks and rollers in stainless steel guarantee fluid manual functionality, high operational safety and superior durability. The transition from the interior to the exterior is effortless and seamless.
Our exclusive, specially-developed locking and automation systems combine outstanding operational ease and security, with exceptional durability. Extremely powerful electric motors, with a tensile force of up to 2.400 kg, silently shift the sliding leaf sections. Various operational modes, such as room switch, remote-controlled, or a fully automated dead-man switch with laser sensors, may be selected, guaranteeing maximum operational ease.
