MB-45

MB-45 is a modern aluminum system used to make architectural elements of interior and exterior development that do not require thermal insulation, e.g. various types of partition walls, windows, doors, including manually and automatically sliding doors, swing doors, vestibules, display cases, cash register boxes, showcases, spatial structures.

The structural depth of window profiles is: 45 mm (frame), 54 mm (leaf), and doors are: 45 mm and 45 mm respectively. Such assumed depths of the sash and frame profiles give the effect of a single plane from 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 obtaining slim and durable window and door structures.

A significant advantage of the MB-45 system is the possibility of bending the profiles, e.g. frames, sashes and battens, which enables the construction of various types of arches and arch structures.

The tightness is ensured by the use of special EPDM synthetic rubber seals, which guarantee resistance to aging during many years of use.

A characteristic feature of the system is its close connection with the window and door systems MB-60 and MB-70. The versatility and attractiveness of the system is additionally increased by the possibility of choosing between several variants of solutions, in the case of various construction details, e.g. bottom seal of door leaves, seals of sliding and swinging doors, shape of glazing beads, shape and height of door thresholds.

The system allows the use of glazing units with a thickness of 2 mm to 35 mm in window leaves and from 2 mm to 26 mm in fixed windows and door leaves.

On the basis of the MB-45 system, smoke-tight doors in class S_a, S₂₀₀ can also be built.

The MB-45 system obtainedpositive results of hurricane tests conducted in accordance with ASTM guidelines and Florida Building Code TAS 201-94, TAS 202-94 and TAS 203-94
