The Next Generation Slider system by Keller minimal windows® provides a seamless transition between indoor and outdoor spaces, achieved through the barrier-free opening of entire window facades.‎ It can reach lengths of up to 50 meters and heights of up to 6 meters.‎
There are four module variants designed to accommodate up to 74 mm insulated glass units or independently open wings weighing up to 1500 kg, meeting the highest standards for stability and security.‎ In the "NG S floor" variant, you have the option of overlapping the outer frame with the floor and wall materials, creating an even more seamless transition between the interior and exterior.‎
By optionally integrating all frame and wing views into the building structure, only vertical profile widths of 26 mm remain visible.‎ The outcome is sunlit spaces with over 99.‎3% maximum transparency, complemented by minimalist framing, creating living environments that emotionally embrace both residents and guests.‎
The choice of materials provides diverse design possibilities for vertical framing and handles, ranging from wood veneer to carbon, glass sword solutions, aluminum, stainless steel, Corten steel, to brass.‎ Additionally, integrated LED ambient lighting is available as an option.‎
Outstanding performance characteristics, including air, wind, and water tightness, as well as thermal solutions up to passive house level, not only facilitate long-term energy savings but also contribute to sustainable increases in user comfort.‎
Whether in a straight, cornered, or curved form, whether manually or motor-operated, or serving as a fixed element, the Next Generation Slider sliding door system offers virtually limitless design freedom.‎
