Aluprof MB-77HS is an aluminium lift-and-slide door system designed for large openings leading to a terrace, balcony or garden. The system combines ease of use with the stability of aluminium and allows large glazed surfaces to be created without taking up interior space when opening.
Thanks to its thermal-barrier construction and the possibility of using high-performance glazing, MB-77HS offers a high level of thermal insulation and indoor comfort. The system is available in 2- or 3-track configurations and allows the integration of a low or flush threshold to facilitate passage between indoors and outdoors.
The system allows the construction of 90- and 270-degree corner sliding doors and can be aesthetically integrated with the Aluprof MB-86N and MB-79N window systems. The door can be equipped with HS-Master automation, operated by button or remote control, as well as the Comfort Close mechanism for controlled closing and safe operation with large and heavy sashes.
Aluprof MB-77HS HI is suitable for residential and commercial projects requiring high-performance aluminium joinery, modern design, large openings and long-term functionality. In the HI version, the system can achieve a Uw coefficient starting from 0.84 W/m²K while maintaining excellent air tightness, water tightness and wind resistance.
