Today, the use of this facade has increased among the luxury and large buildings and towers in the world, and the reason for that is the strength and special beauty of this structure.
1- It is a new and modern view
2- It is a strong view that according to static calculations, the strength of the material used in these structures can be determined.
3- You can use all the space outside the building
4- The facade of the curtain wall has the possibility to use metal-stone or any other material instead of glass.
5- The curtain wall facade is considered one of the lightest modern facades and the reason for that is the use of materials suitable for the type of structure.

The main structure of the curtain wall facade consists of lamellas, the lamellas are aluminum parts that are obtained during the aluminum extrusion process, and depending on the type of structure and according to static calculations, the size of the lamella and its thickness are selected for each project. vertical slats are called mullions and horizontal slats are called transoms; in the structure of the curtain wall facade, after the slats and accessories and other aluminum parts, it is time to install glasses or other covers.
Curtain wall facades are divided into several types based on the type of aluminum lamella used and how the vertical and horizontal lamellas are connected to each other (mullion to transom):
1- Frameless curtain wall facade (without visible aluminum lines on the facade)
2- View of curtain wall face cap (covered)
The difference between the frameless view and the face cap is in the use of special covers, that is, in the face cap view, a cover is used, and the aluminum view is visible, but in the frameless view, the cover is not used, and in the glass view, it is seen without Aluminum appearance
When you look at this view from the outside of the building, there is no visible cover or aluminum parts, and there is a small gap between each glass panel, which is about 1-2 cm, which is actually aluminum structures. lamellas) are located behind this part and on the inside of the building.

2- Different types of glass in different colors can be used in this type of curtain wall facade, such as laminate-darkness glass or double-glazed or triple-glazed glass that act as sound and heat insulation.
3- It does not add extra and dead load to the building.
