Curtain walls are non-structural outer walls for buildings. They keep the weather out, occupants safe, and may well serve for decoration.
Curtain walls made of glass can allow natural light in. There is a great deal of design flexibility for curtain walls as they only need to support their own weight, and are not required to support the building itself. As such, they can be used to upgrade the look of a functional building with minimal concern for weight or design issues. Add the curtain wall that looks right and serves your needs, and that is the building’s new look.
