Facades with continuous fixed glazing

WHY KELLER?

Discover the pinnacle of modern architectural elegance with the minimal windows® highline system. This system seamlessly combines slim aluminium profiles with fixed glazed surfaces, creating spacious and visually stunning fully glazed façades. With generous glass fronts, you can enjoy unparalleled panoramic views.

These frameless glass façades perfectly emphasize the minimalist aesthetic of contemporary residential and commercial buildings. Whether used as fixed glazing or combined with our double- or triple-glazed sliding elements — minimal windows®, minimal windows® 4+, or minimal windows® NGS — these sleek glass fronts exude sophistication and style.

Security

Our systems are equipped with multi-point locking, providing excellent protection against burglary. They are certified according to standards for anti-burglary components and meet RC 2 resistance class requirements. Minimal windows® sliding systems are custom-made and tailored to the individual preferences and requirements of our clients. Additional optional features include linear drives, magnetic contact lock monitoring, or safety sensors. To ensure maximum security, our products are also compatible with a wide range of security accessories.

Drainage

Beneath the lower aluminium frame, our system features a specially profiled PVC base for efficient drainage and thermal bridge interruption. Alternatively, you can opt for an additional concealed drainage channel with a stainless steel cover for a minimalist appearance. Whichever minimal windows® system or combination you choose, we will tailor the drainage solution to your specific needs.

Post-free corners

Creating spacious, light-filled rooms — characteristic of modern architecture — requires flexibility. With our minimal windows® systems, you can design living spaces that seamlessly connect the indoors and outdoors. Our Full Glass Corner technology offers corner solutions without mullions and with full glazing, creating impressive interiors.

Sliding sash “into the wall”

Specially designed wall pockets allow minimal windows® sliding elements to completely disappear into the wall. Whether operated automatically or manually, these sliding elements become entirely invisible, creating a spacious and unobstructed living area.

Stainless steel track and rollers

Our stainless steel guide rail is fully integrated into the lower edge of the outer frame, ensuring optimal sliding performance and quiet operation of the sliding elements. The guide rail and rollers are perfectly matched, providing stability and effortless handling of sliding elements weighing up to 500 kg (1000 kg for 4+, 1500 kg for NGS).

Our self-centering integrated stainless steel rollers are built into the lower profile of the sliding elements, protected from dust and dirt to ensure long-lasting performance.

Flush installation

The outer frame blends perfectly with walls, ceilings, and floors, allowing for a frame installation that is seamlessly “embedded” into the wall cladding. This design provides an uninterrupted, threshold-free transition between indoor and outdoor spaces. Our flush floor-integrated frame profile ensures an elegant appearance.

Threshold-free transition

The built-in minimal windows® freeway track enables a threshold-free passage to the outdoor space, making it fully accessible. The outer frame is completely integrated into the floor, so the track is flush with the surface, eliminating any potential tripping hazards. The freeway system is tested, certified, and maintenance-free.

Color customization

The aluminium frames of our minimal windows® systems are available in a variety of colors and finishes. You can choose powder-coated frames in a wide range of colors, including RAL, IGP, DB, NCS, and more, with matte, glossy, metallic, or textured finishes. Alternatively, you can select anodized frames ranging from silver to black, as well as Granodal® finishes. Customize our products to your preferences with a wide selection of options.

Glass safety railings

For floor-to-ceiling window openings, fall protection is essential. The strength, stability, and suitability of the materials are key to the design of railings. The minimal windows® guardline glass railings* combine superior quality and safety with elegant design. Thanks to modern seamless installation techniques, the components integrate perfectly into the overall architectural concept.

*Country-specific regulations must be observed.

Motorization

Enhance the functionality of your system with our adaptable solutions offering various concealed drive and locking options. Our motorized sliding elements can optionally be equipped with infrared sensors for automated operation. They can be controlled via remote control. Multiple sliding elements with a total weight of up to 2,400 kg can be moved quietly with a single drive.

Insect protection

Ensure discreet protection from unwanted guests with integrated insect screens from Keller minimal windows®. These custom-made screens are nearly invisible and will not obstruct your view. You can match their color to the frame to maintain a harmonious appearance. When not in use, the screens can be easily retracted completely to the side or upward into a wall recess. Available systems include roller insect screens, pleated screens, and sliding door screens.
