Curtain wall
A curtain wall is a non-structural exterior building envelope designed to protect the interior from the elements while supporting only its own weight and transferring lateral wind loads to the building's main structure. Typically comprised of a lightweight aluminum frame with glass, metal, or stone infill panels, these systems span multiple floors and are hung from the exterior of floor slabs to create a continuous, uniform facade. Because they carry no structural load, curtain walls allow for maximum fenestration and natural light penetration, making them a hallmark of modern high-rise architecture and commercial design.
Frequently Asked Questions
Why is curtain wall important in architecture?
A curtain wall is a lightweight, non-structural exterior envelope that protects the interior from weather elements while maximizing natural light and energy efficiency. It is important because it reduces the building's overall structural load and provides architects with immense design flexibility for modern, transparent aesthetics.
What are the different types of curtain wall?
Common types of curtain wall systems include stick-built systems assembled on-site, unitized systems consisting of factory-prefabricated panels, and semi-unitized systems that combine both methods. Other specialized varieties include structural glazing for a seamless glass appearance, point-fixed or spider systems that use minimal hardware, and glass fin systems that utilize glass supports for maximum transparency.
What materials are commonly used for a curtain wall, and how do they impact durability and cost?
Common materials for curtain walls include glass and aluminum frames, though stone, metal panels, and wood-aluminum hybrids are also used. High-performance glass, such as low-E or insulated units, increases initial costs but improves energy efficiency and reduces long-term HVAC expenses. Aluminum is preferred for its strength-to-weight ratio and corrosion resistance, offering a balance of durability and mid-range cost compared to more expensive custom finishes or complex unitized systems.
