MB-86US ST System with invisible window sash

The depth of window section is 77 mm (jamb), 80.8 mm (leaf). The width of external window frame is little what makes glass fitting and the quantity of falling through lighting maximum increased. A design seems to be slender and light. The value of eventual  glass thickness: in the window outer frame – from 7 up to 52 mm, in the casement – from 15 to 60 mm. Such a wide range of glazing allows to mount all found at the market types of double or triple-glazed units, sound proof/acoustic or anti-burglar glass.

In terms of technical properties the MB-86US system meet all requirements concerning energy conservation and environmental protection. The structure of the profile similarly to basic MB-86 system has three variants depending on requirements of thermal insularity: MB-86US ST, MB-86US SI and  MB-86US AERO with the use of modern insulation from aerogel.

The system gives great abilities in created structures: maximal dimensions of casements  exceed standard values for this type of construction. Hs max=2,5 m, Ls max=1,6m. Maximum loaf weight is 150 kg.
