Description

The ALUPROF MB-79N US is a solution which is cost-effective and functional, while meeting every technical requirement. The system is used to build windows featuring sashes that are invisible from the outside. In a row of adjacent fixed and operable windows, it is impossible to distinguish between the two types. The result is an elevation where the windows present a uniform view, irrespective of their function. The MB-79N US system is a finely tuned solution. Two versions of the rebate are available; the A-type frame partially covers the sash, while the B-type frame covers it completely in an ideal imitation of a fixed window. The external surfaces of the glass fitted to the operable and fixed windows lie on the same plane. A custom-designed adaptation profile means that frames and crosspieces from the basic MB-79N system can be used for the concealed sash windows. Large-scale, heavy windows can be produced with the MB-79N US. Like the basic MB-79N window system, these structures are distinctive both for their high thermal and acoustic insulation and their water- and airtight properties. The MB-79N US meets every energy efficiency and environmental protection requirement.
