Description
Our precision-engineered lift-and-slide door system, designed in Germany, brings maximum natural light into modern living spaces while performing flawlessly in all climatic conditions. With a construction depth of 7 inches (179 mm), it is ideal for both renovation and new construction projects. Standard swing doors are also available for more traditional configurations.
The system can be manufactured in impressive sizes, with heights up to 9.5 ft and widths up to 21.5 ft, accommodating glazing up to 50 mm thick. Slender sightlines — 2.5 in (65 mm) at the casement, 3.9 in (100 mm) at the sash, and 4 in (103 mm) at the center fastener — ensure a high passage of light, while the standard U-value of 0.21 – 0.23 Btu/hr·sq ft·°F delivers excellent thermal performance.
Available in white, woodgrain laminates, plain, or metallic colors, the doors can be laminated on the inside, outside, or both sides. For enhanced aesthetics and protection, the system can be upgraded with aluminum clip covers, offering nearly limitless exterior color options, while the interior uPVC profiles ensure low maintenance, high dimensional stability, and reliable functionality.
