MB-45 system - it is so called cold system used for exterior and interior elements, which require lower thermal insulation.
Products manufactured in this system are made of one-chamber section. Their main advantage is durability, variety of application and relatively low price. This system is also successfully used together with MB-70 system and therefore architecture elements, which have changeable thermal insulation, can be constructed. This system offers perfect solutions for partition walls, shop windows, windbreaks and spatial panel walls. Similar to MB-70 this system can also be bend, which makes it possible to construct various bow panel walls.
1 Window-panel seal which ensures tight joint of the window panel packaging and the wing, at the same time it prevents from moisture penetration to the inner side of the window construction.
2 Two-chambered frame and wing profile.
3 Window panel packaging up to 50 mm with a space between the window panels which amounts for 6mm and reaches up to 26 mm.
4 Inner seal protects from water infiltration to the inner part of the window construction.

Depth of the window construction amounts for 45 mm. The depth of the window's section amounts for 45 mm (frame) and 54 mm(wing). Such depths of the frame and wing make it look from the outside as one surface after it is closed. The shape of the profiles enables us to achieve slender and durable windows.


  • possibility of applying to every type of window panel; the thickness of accessible window panel packages reaches up to 26 mm
  • big range of colors; products are painted with RAL varnish
  • possibility of bending the aluminum profiles into arcs


  • seals made of  synthetic rubber EPDM
  • an effective system of water drainage and ventilation

Aluminium colours (180 RAL colours)

DRUTEX S.A standard glazing package consists of 4 mm float glass, 16 mm spacer and 4 mm termofloat glass whereas the space between glasses is filled with gas- argon, which helps to achieve appropriate thermal insulation value.

Standard glazing packageincreased heat infiltration properties and its thermal insulation value amounts for U=1,0 according to norm EN-674.

Moreover, DRUTEX S.A. creates the possibility to choose an appropriate glazing package fully individually, in such a way that it poses even much better protection against burglary, noise as well as excessive insulation.
