MB-23P is an aluminum system for balcony glazing. The idea behind it is horizontally sliding windows. Such windows protect the open space of a balcony from adverse weather — wind, rain, snow — as well as from dirt and noise. At the same time, MB-23P structures hinder break-ins, which is especially important for ground-floor apartments.
The structural depth of the profiles is 53 mm (frame) and 23 mm (sash).
The sashes can be glazed with single glass 4–8 mm thick or with 6.4 mm safety glass. The glass thickness is chosen according to the height of the balcony, its location and the overall dimensions of the panes.

MB-45 is an aluminum system for interior and exterior architectural elements that do not require thermal insulation, for example: various partitions, windows and doors, including sliding doors (automatic and manual), swing doors, vestibules, shopfronts, cashier booths and spatial structures.
The structural depth of the window profiles is 45 mm (frame) and 54 mm (sash); for doors, 45 mm and 45 mm respectively.
The system accepts glazing from 2 mm to 35 mm thick in window sashes and from 2 mm to 26 mm in fixed windows and door leaves.

The MB-59S system is for exterior elements that require thermal and acoustic insulation, for example various types of windows, doors, vestibules, shopfronts, etc.

The structural depth of its window profiles is 50 mm for frames and 59 mm for sashes; the outer face of the sashes lies in one plane. The structural depth of the door profiles, for both frames and leaves, is 50 mm, which gives a flush leaf-and-frame effect on both the outside and the inside.
MB-59S profiles meet the thermal protection requirements for material group 2.1 according to DIN 4108. Their infills can be 4 to 40 mm thick in window sashes and 4 to 31 mm in doors, shopfronts and fixed windows.

MB-60 is for exterior architectural elements that require thermal and acoustic insulation, for example various types of windows, doors, vestibules, shopfronts and spatial structures.
The system's profiles have a three-chamber structure. The structural depth of the window profiles is 60 mm for frames and 69 mm for sashes; for doors, 60 and 60 mm respectively. With these depths, when closed, a window presents a single plane on the outside, and a door's leaf and frame faces sit flush. The profile shape makes for slim yet strong window and door structures.

The MB-60US system is part of the MB-60 thermally broken window and door system. Windows made in it have sashes that are invisible from the outside of the building: adjacent fixed and opening windows look identical. The frames are narrow when seen from outside, so the structure looks light and slender.
A characteristic feature of the system is its link with the other systems of the MB series. This design concept allows many interchangeable components across the systems, for example shared glazing beads, corner cleats, strips, glazing gaskets, rebate seals, shared hardware, locks and hinges, as well as many identical processes, such as pinned joints of transoms and beads, gluing of corner cleats, cutting of various openings, etc.

The MB-70US Concealed Sash system is part of the MB-70 thermally broken window and door system, an in-house development of METALPLAST-BIELSKO S.A. Its aesthetics are identical to the MB-60US design, which has been in our offer since 2001, but its advantage is higher thermal insulation, as the design meets the thermal requirements for material group 1 according to DIN 4108.
In windows made in the MB-70US system the sash is invisible from the outside of the building. Adjacent fixed and opening windows look identical. The frames are narrow, so the structure looks light and slender.
A characteristic feature of the MB-70US window design is its close link with the other systems of the MB series. This design decision allows many interchangeable components to be used, e.g. glazing beads, gaskets, hardware and others.

The MB-78EI fire-rated partition system is for exterior or interior fire-rated partitions with single- and double-leaf doors of fire resistance classes EI15, EI30, EI45 or EI60 according to PN-B-02851-1:1997.

The MB-78EI system is based on thermally broken aluminum profiles. The structural depth of the profiles is 78 mm. The profiles have a low U-value thanks to, among other things, special 34 mm profiled thermal breaks. The system accepts all standard glass of the corresponding classes (infill thickness 13 to 49 mm). Smoke-control structures in several versions can also be made in it. Tests at the Building Research Institute in Warsaw have also shown that products made in this system have very good sound insulation (up to 40 dB).

SPECTRAL 45 is an aluminum system for interior and exterior architectural elements that do not require thermal insulation, for example: various partitions, windows and doors, including sliding doors (automatic and manual), swing doors, vestibules, shopfronts and cashier booths.
The structural depth of the window profiles is 45 mm (frame) and 53 mm (sash); for doors, 45 mm and 45 mm respectively. With these depths, when closed, a window presents a single plane on the outside, and a door's leaf and frame faces sit flush. The profile shape makes for slim yet strong window and door structures.
Glass or other infills are fitted with glazing beads and glazing gaskets. The system accepts glazing from 2 to 26 mm thick. Such a wide range of infill thicknesses allows all standard and non-standard glass to be used.

SPECTRAL 60 is an aluminum system for exterior architectural elements that require thermal and sound insulation, for example various types of windows, doors, vestibules and shopfronts.
The system's profiles have a three-chamber structure. The structural depth of the window profiles is 60 mm for frames and 68 mm for sashes; for doors, 60 and 60 mm respectively. With these depths, when closed, a window presents a single plane on the outside, and a door's leaf and frame faces sit flush.
The system accepts glazing from 16 to 41 mm thick. Such a wide range of infill thicknesses allows all standard and non-standard glass to be used.

The MB-SG50 system is designed for lightweight enclosures — curtain and infill types — as well as roofs and skylights, for general-purpose buildings. It achieves thermal insulation in material groups RMG 2.1–1 according to DIN 4108.
The load-bearing structure of MB-SG50 rests on an aluminum mullion-transom frame with 50 mm wide profiles. The transoms are attached to the mullions with brackets, which allows various installation methods.
The aesthetics and lightness of the structure deserve attention: the infills are separated by a 16 mm gap, and the visible profile width from inside the room is only 85 mm.
The system allows the outer panes to be fixed mechanically, continuously or at points, at the corners of the insulated glass unit, according to individual requirements.
Another very important feature of MB-SG50 is the lateral fixing of the aluminum frames, which allows opaque panels to be mounted on a blind wall.
