ALT С43 Window

ALT С43 is a system of non-insulated profiles for the construction of elegant and affordable aluminium windows. This is an optimal solution for application in administrative, commercial, manufacturing and residential facilities in warm climate but it can also be used as an interior partitioning, winter garden system as well as entrances without high-energy efficiency requirements.

Different infill units can be used in ALUTECH ALT C43 system, such as glass, insulated glass units or sandwich panels with thickness from 4 to 24 mm. Infill units are installed on special bearing plates in accordance with installation scheme. The same bearing plate is installed into fixed lights parts of the structure and sashes.
