The MB-77HSB system was designed bearing in mind mainly the needs of the Belgian market. It is based on a proven, extended and valued system of lift-and-slide balcony doors [MB-77HS] (https://aluprof.com/producenci/oferta/systemy-okienno-drzwiowe/mb-77hs-drzwi-balkonowe-podnoszono-przesuwne#wizualizacja).
Appropriate insulation of the structure is ensured by profiled thermal breaks and additional insulating elements inside the aluminum sections. An important feature of the internal construction of balcony doors is a 2 mm ventilation gap between the glass packet and the insulating insert operating at the edge of the glass along its entire circumference.
The profile design allows to produce exclusive doors with large dimensions, filled with single or double glazing, and the materials and technical solutions used help to achieve a high degree of thermal and acoustic protection. Thanks to its properties, this system is ideal for single-family houses as well as comfortable apartments or hotels. The MB-77HSB system holds an ATG certificate issued by the Belgian Research Institute UBAtc.
