A glass curtain wall is a non-structural outer covering of a building, typically made of large glass panels framed with aluminum or steel. It serves as a lightweight façade system that protects the interior from weather elements while allowing natural light to penetrate deep into the building. Unlike load-bearing walls, curtain walls do not support the building’s structural weight; instead, they are anchored to the main framework and designed to resist wind, water infiltration, and thermal expansion.
Modern glass curtain walls enhance energy efficiency with insulated glazing, UV coatings, and ventilation features. They are widely used in commercial skyscrapers, office buildings, and contemporary architectural designs for their sleek, aesthetic appeal and functional benefits.
