Insect Screens

Keller minimal windows® offers system-integrated, tailor-made insect screens for effortless, long-term protection against unwanted guests. The insect screens are virtually invisible, so the plissé or fly-screens options ensure an almost unhindered view. The screen color can be matched to the color of the frame. The insect screens can be fully retracted into the frame, sideways, or upwards, completely concealed, when not in use.

Glass Safety Balustrades

Floor-to-ceiling window openings require fall protection. Key factors in their construction* are strength, stability and the suitability of materials.

Motorized Sliding Leaf System

Customized system configuration allows for a range of concealed electric drives and locks for optimal ease of operation. Motorized sliding leaf systems function via effortless remote-control operation, and can be integrated with infrared detectors, or a manual dead-man’s switch. A single motor can noiselessly deploy several sliding sections, with a combined weight of up to 2.400 kg. This allows automated, telescopic operation, which can open large surface areas. We endeavor to design the slimmest solutions, combining top-quality minimalistic design with optimal functionality.
