Nihon Keisou provides curtain walls in addition to aluminum window frames. While a window frame is the frame of a window mounted in an opening of a wall, a curtain wall is a wall-like partition consisting of a set of window frames. Curtain walls can be arranged freely.

For example, the can be used as window frames or as walls of high-rise buildings, condominiums, stores, etc.
