MB-79N CASEMENT Outward-opening Windows

High-performance aluminum window system with thermal break

MB-79N Casement is an outward-opening window system with thermal break, designed for creating external architectural elements – various window types, vestibules, display windows and spatial structures – providing excellent thermal insulation and acoustic performance, as well as highest classes of air and water tightness. The system is available in three variants (E, ST and SI) with different technical parameters for various needs. The profile construction depth is 70 mm for the frame and 79 mm for the sash, and they are designed for triple glazing. Thanks to the wide range of profiles and their rigidity, the system allows the production of large-scale heavy structures with a maximum sash weight of up to 180 kg and dimensions of up to 1400 x 2700 mm or 2400 x 2500 mm. The system is compatible with other ALUPROF solutions, especially with the MB-79N family, providing interchangeability of components.
