aluminium / metalplast systems / mb-70us

The MB-70 US (HIDDEN CASEMENT) is a part of the window-door system of METALPLAST BIELSKO SA with a thermal barrier MB-70. Taking into consideration its aesthetics, the structure is identical to MB-60US, which has been in our offer since 2001. Its advantage is increased thermal insulation, as it meets the thermal requirements for material group 1 according to DIN 4108.

The windows made in MB-70US system have sashes/casements that cannot be seen from the external side of the building. The position of the adjacent fixed and openable windows cannot be distinguished. The width of the window frame from the external side is small, thanks to which the structure gives an impression of a shapely and delicate look.

Similarly to the standard structures, the windows built in the MB-70 US system have effective water drainage and ventilation system from the glass chamber and from the chamber between the sash and the casing . The ventilation and drainage openings are covered with caps made of plastics.

The characteristic quality of MB-70US window system is that it is closely tied-in with other systems of METALPLAST BIELSKO series. Adapting such structural design allowed to achieve and use many common elements, e.g. common glazing beads, hardware, profiles gaskets, etc.
