Introduction of Curtain wall 

A curtain wall is an outer covering of a building in which the outer walls are nonstructural but are attached to the building structure and used to keep out the weather. Because the curtain wall is nonstructural it can be made of a lightweight material (e.g., aluminum-framed walls containing infills of glass, metal panels, or thin stone), reducing construction costs. The use of glass as the curtain wall has the advantage of allowing natural light to penetrate deeper within the building. Of note, the curtain wall facade does not carry any dead load weight from the building other than its own. In addition, a curtain wall is designed to resist air and water infiltration resist sway induced by wind and seismic forces acting on the building, and its own dead-load weight forces.  

In a curtain wall the external surface is the waterproof layer, and hence all parts of the structure behind are considered dry. This is not to say that there is no chance of moisture, as condesation must still be considered. Normal practice would be to allow a small amount of air movement behind the outer skin, but in the case of PV it should be increased, if possible, to provide some cooling from the rear surface of the PV. The advantage of the curtain wall is that it allows a continuous skin incorporating all the facade elements—windows, PV, and blank panels within a proven design. These systems are complex and expensive without the PV and so the additional cost may be more readily absorbed into such a facade It should be noted that the use of terms “rain screen” and “curtain wall” varies internationally.

Ok, thank you for reading so far, you must get a fundamental knowledge about aluminum windows, should you need further information, please contact me at the below information:
