Curtain wall systems clad a building envelope with glass and aluminum to protect the interior from the elements and creates a safe and comfortable work environment for the building occupants. Curtain walls are designed to only carry their own weight. The wall transfers wind loads to the main building structure, also known as the main wind force resisting system (MWFRS), at connection points in the floors or columns of the building. A curtain wall is designed to resist air and water infiltration, as well as, sway created by wind and seismic forces, and its own weight.

Curtain walls may span from floor to floor, used in punched opening applications, or span multiple floors, and take into consideration design requirements such as: thermal expansion and contraction; building sway and movement; water diversion; and thermal efficiency for cost-effective heating, cooling, and lighting in the building.


  • Composed of large glass units that are assembled and glazed within a factory. 

  • Applicable for office buildings or commercial areas of the high-rise buildings. Benefits in speed of installation.

  • Suitable for when a large volume of prefabricated unitized panels are required, the higher filed labor costs are expected and higher performance is needed (for wind load, air/moisture products, seismic performance) for taller structures.

  • Applicable for low to mid-rise curtain walls.

  • Composed of mullion, panel, vision glass and spandrel glass which is to be glazed at a site. (Also known as knockdown system)

  • The lead times are often much shorter for fabricated materials to be delivered to the site.
