Technical description:

MB-70 - Window and door system with thermal insulation

MB-70 is a modern aluminum system used to provide thermal and acoustic insulation of architectural elements of outdoor construction, eg: various types of windows, doors, vestibules, sites, spatial constructions.
System profiles have a triangular structure. The structural depth of the window sections is 70 mm (frame), 79 mm (sash) and doors respectively 70 mm and 70 mm. Such assumed depths of the sash and frame sections give the effect of a single plane from the outside after closing - in the case of a window and the effect of faced surfaces of the sashes and the frame - in the case of the door. The shape of the profiles allows for slim and durable window and door constructions.

The MB-70 system is characterized by a remarkably low U-value due to the use of special thermal inserts and seals. This is important in the times of increasing energy and environmental requirements. The Uf coefficient for MB-70 system constructions depends on the profiles and accessories used between 1.5 and 2.39 W / m2K. The system uses profiled thermal omega shaped spacers with the width of 34 (windows) and 24 (doors) mm of fiberglass reinforced polyamide. The offered shape of the inserts increases the stiffness of the profile with respect to the flat inserts and facilitates dehydration of the sections thus ensuring proper thermal insulation in all atmospheric conditions. The thermal interlaces used in the windows are additionally sealed at the joint of the profile and spacers, and the dividers divide the chamber between the internal and external aluminum sections into three parts.
Tightness is ensured by the use of special gaskets made of two-component EPDM synthetic rubber: solid and cellular, which guarantees resistance to aging over many years of operation and very good thermal insulation. The MB-70 is the first system in which this kind of material is used to make a central seal.

The system allows the use of shaft glazing units with the thickness ranging from 21 mm to 57 mm in window sashes and from 12 mm to 48 mm in solid windows and door sashes. Such a wide range of fill thicknesses guarantee the possibility of using all typical and non-standard panes.

Wide selection of colors in the standard palette makes it possible to meet the needs of the most demanding clients. Color coatings are made by powder coating or anodizing.

MB-70 system is the basis of solutions with increased thermal insulation: MB-70 HI, MB-70US HI and cold - warm façade based on MB-70CW windows.
