Masonry curtain walls are exterior claddings of brick or stone masonry veneers supported by the building's structural frame.

Firstly, steel shelf angles are fixed to the spandrel beam of the structural frame, and the insulation is placed over it.

Then, the flashing is laid, the masonry units are placed directly on it and secured using a high-bond mortar.

Further, a backup wall is constructed by arranging hollow concrete masonry units and grouting vertical reinforcing bars into their cores. The wall is then coated with an air- and water-resistant material.   

Subsequently, the next courses of masonry units are laid to level up with the backup wall, followed by inserting the insulation and placing the joint reinforcement and masonry ties. This process is repeated till the desired height of the wall is achieved.  

Alternatively, curtain walls can be installed by hoisting prefabricated panels into place and securing them.

Vertical and horizontal expansion joints are also provided in the curtain walls.

Additionally, providing a cavity behind the curtain wall along with weep holes can mitigate moisture entry into the structure.
