In the case of adjacent fixed and opening windows, it is impossible to distinguish their position, which leads to a uniform appearance of the building façade regardless of the function of individual windows.

The external surfaces of the glass in opening and fixed windows lie on one plane, which ensures a consistent appearance. Thanks to a special adaptive profile, it is possible to use frames and battens from the basic system in windows with a hidden sash. MB79N.
System MB79N US enables the production of large and heavy windows while maintaining high thermal and acoustic insulation as well as water and air tightness, which meets the requirements for energy saving and environmental protection.
