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)

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
