What Is A Curtain Wall?

A curtain wall is a non-structural exterior wall system that envelops a building’s facade, providing weather protection and aesthetic appeal. Unlike traditional load-bearing walls, curtain walls support their weight through the building’s framework, allowing for extensive use of glass and other lightweight materials.

What Is A Curtain Wall Used For?

Curtain walls serve multiple purposes in modern construction, including:

  • Providing thermal insulation and weather resistance.
  • Maximizing natural light and views.
  • Enhancing the aesthetic appeal of buildings.
  • Improving energy efficiency through the use of advanced glazing systems.

What Is A Curtain Wall Made Of?

Curtain walls typically consist of the following components:

  • Glass panels or infill materials (such as metal panels or stone veneers).
  • Aluminum or steel framing members.
  • Sealants and gaskets to provide weatherproofing.
  • Structural support elements, such as mullions and transoms.

What Does A Curtain Wall Look Like?

A curtain wall has a sleek and modern appearance, often characterized by large expanses of glass interspersed with narrow metal framing elements. The transparency and reflective properties of the glass give curtain walls a distinctive aesthetic that complements contemporary architectural designs.

What Is A Curtain Wall In Construction?

In construction, a curtain wall is installed as an exterior cladding system, typically during the later stages of building construction. The installation process involves assembling pre-fabricated components on-site and anchoring them to the building’s structure using anchors, brackets, and other fastening systems.

Curtain Wall Building Examples:

Several iconic buildings around the world feature innovative curtain wall designs, including:

  • The Burj Khalifa in Dubai, UAE
  • One World Trade Center in New York City, USA
  • The Shard in London, UK

What Is A Curtain Wall Castle?

Curtain Wall Design:

Curtain wall design encompasses various factors, including:

  • Structural integrity and load-bearing capacity.
  • Thermal performance and energy efficiency.
  • Aesthetic considerations, such as transparency, color, and texture.
  • Compliance with building codes and regulations.

Curtain Wall Types:

There are several types of curtain walls, including:

  • Stick-built curtain walls assembled on-site from individual components.
  • Unitized curtain walls prefabricated off-site and installed as complete panels.
  • Point-supported curtain walls featuring glass panels supported by tension cables or rods.


Curtain walls have revolutionized modern architecture, offering architects and designers unparalleled flexibility in creating visually stunning and energy-efficient buildings. Understanding their composition, uses, and design considerations is essential for anyone involved in the construction or design of contemporary structures.


What Is Considered A Curtain Wall?

A curtain wall is an outer covering of a building in which the outer walls are nonstructural but are attached to the building structure and used to keep out the weather.

What Is The Difference Between A Window Wall And A Curtain Wall?

Window walls are built one floor at a time and are supported by the slabs above and below them. In other words, window walls are built within the slab edge. Curtain walls are structurally independent and don’t require support on every floor. They tend to span multiple stories and are built outside the slab edge.
