Door system 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.
The shape of the profiles enables us to achieve slender and durable windows.

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.

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

Door system MB-60 is so called warm system.
Threechamber section consists of three chambers combined by a separator, which shows perfect thermal properties. Therefore it is possible to apply two-colour profiles- different outer and inner. The system of seals made of synthetic rubber EPDM increases window thermal insulation and reduces condensation of water vapour. Doors manufactured in this system are adapted to any climatic conditions and all kinds of constructions, especially in house building, where thermal and acoustic insulation values are often factors which influence the choice of the doors.

The shape of the profiles make it possible to achieve slender and durable door constructions System MB-60 shows low thermal insulation value U mainly thanks to the application of specially designed thermal separators and seals. Doors are perfect for every climate zone , in each type of buildings, also in house buildings. When it comes to form, aesthetics, durability and function the doors are consistent with the requirements of buildings thermal protection, ecological and healthy standards. Their usage guarantees savings of heat and protects from cold and noise.

Construction depth of the section amounts for 60 mm (frame), 69 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 and doors.

Designing:
  • big range of colors; products are painted with 180 RAL varnish
  • possibility of applying to every type of door panel; the thickness of accessible door panel packages amounts for 5-41 mm
Tightness and insulation:
  • seals of the highest quality are made of synthetic rubber EPDM

MB-70 is a modern aluminium system intended for realizations of exterior architectural building elements requiring thermal and acoustic insulation, such as: various types of windows, doors, vestibules, display windows or spatial structures.

The system profiles have a three-chamber structure. The structural depth of the window sections is equal to 70 mm (frames) and 79 mm (casement), and for doors: 70 mm and 70 mm respectively. Such assumed depths of casement and frame sections give the effect of one surface from the exterior side after closing - in the case of the window, and the facing effect to the surface of casement and frames - in the case of doors. Shape of the profiles allows achieving slender and resistant window and door structures. In the MB-70 system, it is also possible to produce windows with the so-called hidden casement¬Ě MB-70US and the MB-70 Industrial¬Ě, finding its application during modernisations of post-industrial historic and monumental objects.

The MB-70 system is characterized by a very low value of the overall heat-transfer coefficient Uf, thanks to application of the thermal breaks and gaskets. This is of a great significance in the times of increasing demands for the energy management and the environment protection. The value of heat transfer coefficient for constructions of the MB-70 system - depending on the applied profiles and accessories ranges between 1.5 and 2.39 W/m2K. In this system, the profiled "omega"- shaped thermal breaks are applied, of a width equal to 34 mm (windows) and 24 mm (doors), made from polyamide reinforced with fibreglass.

The offered shape of thermal breaks increases the profile rigidity as compared to flat breaks and facilitates the section drainage, ensuring the appropriate thermal insulation in all atmospheric conditions at the same time. The thermal breaks applied in the windows have additional gaskets at the joining point with the sections, as well as tongues dividing the chamber between the internal and external aluminium sections into three parts. Owing to the application of, among others, thermal breaks of such shapes, it is not necessary to fill the space between them with polyurethane foam or foamed styrene inserts, in order to increase their thermal insulation. The tightness is ensured thanks to using the special gaskets made of two-component EPDM synthetic rubber: solid and cellular, which guarantees its ageing resistance during the long-lasting exploitation, as well as very good thermal insulation. MB-70 is the first system in which this type of material was used for creating the central gasket. The system allows application of sets of glass panel of the thickness equal from 21 mm to 57 mm in window casements, and from 12 mm to 48 mm in fixed windows and door leafs. Such a wide thickness range of infill guarantees the possibility to apply all typical and untypical glass panels

MB-70 is a modern aluminium system intended for realizations of exterior architectural building elements requiring thermal and acoustic insulation, such as: various types of windows, doors, vestibules, display windows or spatial structures.

The construction of the windows and doors system with thermal barrier MB-70HI is based on well-proven, well developed and highly appreciated base systems MB-70.

The thermal insulation performance of frames of this system is considerably higher than the insulation performance of base systems.
The value of heat transfer coefficient Uf for constructions of the MB-70HI system - depending on the applied profiles and accessories ranges between 1.11 and 2.3 W/m2K.

Enhanced thermal insulation performance is achieved due to placing special insulating inserts in the central insulating chamber, formed by connecting aluminium profiles with thermal breaks. Thus formed inserts reduce heat transfer through this chamber due to low value of heat transfer coefficient.

The central location of inserts additionally limits convection and thermal radiation.
The MB-70HI doors and windows, just like in the case of the base system, find application both in individual assemblies and in aluminium facades.
