Curtain walls are non-load bearing external walls that connect to a building's structural frame. They can be made from a variety of materials, including glass, metal, and stone.

Curtain walls offer a number of benefits, including their ability to create a sleek and modern look and improve energy efficiency.

Curtain walls are typically installed using a process called unitization. Unitization involves assembling the curtain wall components in a factory and then transporting them to the construction site for installation.

There are a number of different types of curtain walls, including stick-built curtain walls, unitized curtain walls, and semi-unitized curtain walls. Each type of curtain wall has its own advantages and disadvantages.
