Such a curtain wall method can be mechanized, can be manufactured in a factory, can be easily controlled in quality, can be lightened in the outer wall, and can produce a more exquisite appearance depending on materials used. And most of the present high-rise buildings are being constructed by this method.

Typically, the curtain walls are configured to connect a plurality of double-glazed windows by mounting a frame to two neighboring double-glazed windows vertically erected so as to be spaced apart from one another. In this case, the frame applied to the conventional curtain wall is generally made of aluminum in order to improve the adhesion with the double-layered glass. However, aluminum has a high thermal conductivity, so that external heat is quickly transferred to the room.

That is, when the air temperature is low as in winter, external cool air flows into the room through the aluminum frame as it is, and external heat is introduced into the room when the air temperature is high as in summer. In addition, even when the room is cooled and / or cooled, cold air or warm air in the room quickly escapes to the outside, thereby deteriorating overall insulation performance of the building. In order to solve such a problem, when the frame is made of synthetic resin, the mechanical strength of the frame is lowered, so that the structural rigidity of the curtain wall is deteriorated.

On the other hand, when the frame constituting the curtain wall is made of aluminum as mentioned above, the frame unit price is increased, and thus the entire construction cost of the curtain wall is increased.
