It is the formation of the building envelope created with aluminum curtain wall systems with a modular technique. All components that make up these modules are turned into finished products in a controlled factory environment (off-site) and assembled on-site.

This system is not very new in the design of aluminum facade systems, but it is a preferred method, especially in high-rise buildings, instead of the widely used bar systems. In these systems, grids consisting of horizontal and vertical profiles are not anchored to the building beforehand. Instead, a single panel is formed in the factory environment, including the horizontal and vertical profiles, with the glass, composite profile on top of it, usually at a distance that can exceed a floor space and a few horizontal partitions, and is assembled ready-made for the building.
