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” MB-70US and the MB-70 “Industrial”, 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.

A wide choice of colours in the standard palette makes it possible to meet the needs of our most demanding customers.

The MB-70 system forms the basis for solutions featuring enhanced thermal insulation performance, such as: MB-70HI, MB-70US HI and for a curtain wall based on MB-70CW HI windows.

Window and door systems - General information

ALUPROF aluminium systems allow to fabricate many different types of windows and doors, depending on the scope and specific requirements for functionality, aesthetics, thermal insulation, burglary resistance, smoke control or fire resistance. These include both structures with no thermal insulation designed to fabricate internal partition walls and door (MB-45, MB-45 Office, MB-EXPO) or balcony developments (MB-23P system ), and solutions based on thermally insulated profiles (MB-60, MB-70, MB-59S). A significant part of thermally insulated systems is available in “HI” variant, and is characterized by special inserts into the profiles that lower the thermal conductivity coefficient.

The best thermally insulated structure offered by ALUPROF is the MB-104 PASSIVE system, which uses innovative materials and technical solutions. It’s one of the major ALUPROF product that perfectly meets the objectives of energy-efficient and passive buildings.

The MB series includes not only structures with the most common types of opening: side/bottom, but also lifting sliding patio doors MB-77HS, sliding windows & doors MB-Slide / MB-Slide ST, pivot windows“Pivot”, outward openable windows (e.g. MB-59S Casement) or windows dedicated to specific façade solutions, such as MB-60EF. We also offer “Industrial” type windows, dedicated to the revitalized historic buildings.
Numerous MB series systems allow for the fabrication of accordion doors, burglary resistant constructions, and smoke exhaust windows. For buyers who want to reconcile the right technical parameters with an affordable price, we offer a whole range of economic solutions, such as MB-45S, MB-59SE, and MB-60E.
Our window & door systems offering includes special, fire- and smoke-resisting partition walling: MB-78EI with the fire resistance class of EI15—EI90 and the MB-118EI with the fire resistance class of EI120. This group of products is completed by smoke-resisting doors with no fire resistance: MB-45D.
ALUPROF’s wide range of solutions is systematically developed in order to best meet the needs of contemporary architecture and meet the requirements of increasingly stringent standards and regulations.
