MB-70 window and door system with thermal insulation

MB-70 is a modern aluminium system used to make exterior architectural elements that require thermal and acoustic insulation, such as windows and doors of different types, vestibules, showcases, and spatial constructions.

Profiles of the system consist of three layers. Construction depth of window profiles is: 70 mm (frame), 79 mm (wing), and door, respectively: 70 mm and 70 mm With windows and doors closed, the assumed depths of casement and frame sections give the effect of a single plane for windows and the effect of the leaf being flush with the frame surface for doors, when looking from the outside. The shape of profiles allows obtaining slender and durable structures of windows and doors.

The MB-70 system is characterised by extra low heat transfer coefficient U due to the use of special thermal separators and gaskets. This is particularly important in the age of growing expectations in terms of energy management and environmental protection. Coefficient Uf for the structures of the MB-70 system, depending on profiles and accessories used, is from 1.5 to 2.39 W/m2K. The system uses profiled omega-shaped glass fibre-reinforced polyamide thermal separators 34 mm (windows) and 24 mm (doors) in width. The available shape of the separators improves profile stiffness in relation to flat separators and facilitates water removal from sections, thus ensuring proper thermal insulation under any weather conditions. Thermal separators used in the windows are additionally sealed at the point of contact between the section and separator and have projections to divide the chamber between the internal and external aluminium sections into three parts.

Tightness is ensured by the use of special gaskets made of EPDM two-component synthetic rubber: solid and cellular, to provide resistance to ageing during long-term use and very good insulating power. MB-70 is the first system which uses this material to make the central gasket.

The system allows the use of pane sets with a thickness of 21 mm to 57 mm in window casings and of 12 mm to 48 mm in fixed windows and window leaves. Such a wide range of filling thicknesses ensures that all typical and non-standard panes can be used.

A wide range of colours in the standard palette can satisfy the most demanding customers. Colour coatings are made by powder coating or anodising methods. 

The MB-70 system is the basis for improved thermal insulation solutions: MB-70 HI, MB-70US HI and a warm-cold façade based on the MB-70CW HI windows.
