Glass Curtain Wall System

Glass curtain walls are lightweight aluminum-framed facades housing glass or metal panels. These glazing systems don’t support the weight of a roof or floor.Instead, gravity loads and wind resistance transfer from the surface to the building’s floor line. Curtain walls are often part of a building envelope or comprises one part of a wall system. Each glazing system requires careful integration with other adjacent structural elements such as wall claddings, roofs, and wall details. Curtain wall systems range from standard prefabricated systems to specialized custom wall units. Increased costs often come with additional customization and larger sizing.

• These aluminum framed glass wall systems are a hallmark of modern architecture, dating back to the 1930’s. Increases in the availability of inexpensive bulk aluminum following WWII led to their popularity and wide-spread adoption.
• Unitized and modular glass curtain wall systems work as both interior and exterior glazing applications. Each offers various advantages and disadvantages. Interior glazed systems allow for glass or opaque panel installation into the curtain wall openings from the interior of the building.
