During the construction process, numerous important decisions need to be made, and choosing the right glazing that suits your requirements is one of them. The triple-glazed minimal windows®4+ Premium elements from Keller consist of three glass panes within a sealed frame. The space between the panes is filled with inert gas, which is heavier than the surrounding air and thus provides excellent sound and thermal insulation properties. Our minimal windows®4+ offer outstanding energy efficiency and are ideal for installation in low-energy and passive houses.
Our systems are equipped with multi-point locking, providing excellent burglary protection. They are certified according to standards for burglar-resistant components and meet resistance class RC 2. The minimal windows® sliding systems are custom-made and individually tailored to the preferences and installation requirements of our customers. Optional additional features include a linear drive, lock monitoring with magnetic contacts, or security sensors. To ensure maximum security, our products are also compatible with a wide range of security accessories.
Creating spacious open areas, which are characteristic of modern, light-filled buildings with curved forms, requires flexibility. With Keller's minimal windows® systems, you can create unique living spaces with a seamless transition between indoors and outdoors. The full-glass corner technology also contributes significantly to this appearance. Post-free corners with full glazing are an efficient way to create impressive, expansive interior areas. Our unique frame profile seamlessly integrates with the sliding panel, allowing the two sliding elements to perfectly close together at a 90° angle.
Pocket Sliding Doors
Pocket Sliding Doors
Specially designed pocket sliding doors allow the minimal windows® sliding panels to fully disappear into the wall, making the automatically or manually operated sliding elements completely invisible and creating an even larger space. The barrier-free transition to the outside is also ensured.
Stainless Steel Track and Roller Guide
Stainless Steel Track and Roller Guide
Our stainless steel track, fully integrated into the bottom edge of the outer frame, ensures optimal sliding performance and silent operation of the transparent sliding panels. The system is completely maintenance-free. The roller guide resting on the track fits perfectly and is designed to match the track.
The self-centering integrated stainless steel roller guide is concealed and mounted in the lower profile of the sliding panels. With this special design, dust or dirt that could affect the sliding performance is kept away from the operating system as much as possible. The high-quality stainless steel rollers ensure high stability under load and effortless operation of the sliding panels weighing up to 1,000 kg.
For reliable drainage, a specially designed PVC hollow chamber profile is used. This drainage profile is installed below the lower aluminum frame profile.
Alternatively, a concealed drainage channel with a stainless steel cover is also available. Regardless of which minimal windows® system or combination of systems you have chosen, we customize the drainage system according to your needs to ensure reliable water drainage.
The outer frame can be fully integrated into walls, ceilings, and floors, creating a flush finish. In the open position, this creates a seamless transition between the interior and exterior areas without any thresholds. The integrated stainless steel track is installed flush into the floor, without any protruding elements. Another advantage is the maintenance-free nature of the system.
The flush-mounted minimal windows® freeway track provides a threshold-free passage to the outside, making it fully accessible. The outer frame is fully integrated into the floor, so the track is level with the floor, eliminating any obstacles to trip over. The freeway system is tested, certified, and maintenance-free.
