Curtain Wall
Definition and meaning of Curtain Wall in real estate.
A curtain wall is a non-structural exterior building facade that is typically made of lightweight materials such as glass, aluminum, or stone veneer. It is designed to keep out weather elements while carrying only its own weight rather than supporting the structural loads of the building.
In more detail
Curtain walls are common in commercial high-rise buildings and modern residential designs. Because they are not load-bearing, they can be constructed of thin, lightweight materials that allow natural light to penetrate deep into the building. These walls transfer wind and gravity loads back to the building structure, usually at the floor slabs or columns.
Proper installation is critical to prevent air and water infiltration, which can lead to mold or structural damage over time.

Frequently asked questions
Is a curtain wall load-bearing?
No, a curtain wall does not support the weight of the building roof or floors, it only supports its own weight and transfers wind forces to the main structure.
What is the difference between a storefront system and a curtain wall?
Storefront systems are typically used for ground-floor retail displays and are supported by the slab, while curtain walls are suspended across multiple stories to cover the building exterior.
