MB-77 HS

MB-77HS lift-and-slide doors are a top-tier choice for seamlessly joining interior spaces or conservatories with outdoor zones like terraces, balconies, or gardens.

Thanks to their quiet, fluid sliding motion, they effortlessly extend living areas to the outside, letting in natural light and fresh air. Their design allows the sash to glide without invading internal or external space, making them ideal where saving room matters. With high thermal insulation and tight sealing against wind and rain, MB-77HS meets all the essential standards for energy efficiency.
