MB-79N

The MB-79N window profile is an advanced aluminum system that combines high thermal insulation and modern design, ideal for demanding architectural applications. With an installation depth of 79 mm for the window sash and 70 mm for the frame, MB-79N offers unparalleled durability and aesthetics.

The MB-79N system is characterized by excellent thermal insulation with a window Uw value from 0.79 W/(m²K). This is made possible by the use of advanced seals and insulating inserts, making MB-79N meet the highest energy standards. The possibility of using glass of up to 63 mm in windows and 54 mm in doors, including acoustic and burglar-proof glass, further increases the functionality of the system. With the ability to build narrow, opening windows and doors, MB-79N will be perfect for modern architectural projects.
