Windows more light


Windows made in the MB-70US Aluprof aluminum profile system have sashes that are invisible from the outside of the development. In a sequence of adjacent fixed and opening windows, the view of all quarters is the same. The width of the window frames is small, so the structure gives the impression of being slender and light, and much more sunlight enters the room.

The undoubted advantage of this solution is high thermal insulation: the heat transfer coefficient Uf, depending on the profiles and accessories used, ranges from 1.35 to 2.16 W/m2K. In the HI version, the Uf coefficient ranges from 1.31 to 2.0 W/m2K.

Burglar-proof structures can also be made based on this system.
