  1. Modern design.
  2. Possibility of bending profiles, including: door frames, sashes and battens.
  3. Close connection with the MB 60 and MB 70 window and door systems.
  4. Gaskets made of EPDM synthetic rubber.
  5. Advanced technological solutions.

The system is the basis for special solutions: MB-45D smoke-tight partitions and doors and the so-called "notch" MB-45S.

It also allows for the construction of doors and external glazing in situations that do not require thermal insulation of profiles.

The structural depth of the window sections is: 45 mm (frame), 54 mm (leaf), and the door: 45 mm and 45 mm, respectively. Such adopted depths of the sash and frame sections give the effect of one plane on the outside after closing - in the case of a window, and the effect of flush surfaces of the sash and frame - in the case of doors. The shape of the profiles allows for slim and durable window and door structures.

The system allows the use of glass sets with a thickness of 2 mm to 35 mm in window sashes and from 2 mm to 26 mm in fixed windows and door sashes.
