Exploring the Difference Between Window Wall, Storefront, and Curtain Wall Systems in Architecture

Introduction:

In the world of architecture, selecting the right fenestration system is crucial to achieving a successful building design. This blog post aims to provide a comprehensive understanding of three main system types: Window Wall, Curtain Wall, and Storefront. By exploring their unique features and benefits, architects can make informed decisions when it comes to selecting the most suitable window system for their projects.

• Window Wall System:

  • Designed to maximize natural light and provide unobstructed views

  • Typically used in platform based construction on mid and highrise
    buildings.

  • Composed of prefabricated panels that are mounted to floor slabs.
    Spanning from floor to ceiling on building heights up to 13ft

  • Considerations: Wind load, thermal insulation, water penetration, and
    condensation control
    

• Curtain Wall System:

  • Designed to protect the building from external elements and provide
    continuous moisture and thermal protection.

  • Composed of aluminum, steel or wood mullions and varying panels

  • Typically used in commercial and high-rise buildings

  • Considerations: Wind load, thermal insulation, water penetration, and condensation control

  • Can be field built (stickbuilt) or shop built (untized) depending on project constraints
    

• Storefront System:

  • Designed to be cost-effective and aesthetically appealing

  • Typically used in low-rise commercial buildings

  • Consists of an aluminum frame with glass panels that are inserted into the frame

  • Considerations: Wind load, thermal insulation, water penetration, and condensation control
    
    

• Selecting the Right Window System:

  When selecting a window system, it is important to consider the specific needs of your building design, such as energy efficiency, aesthetics, and structural requirements. You must also consider the environmental factors that could affect the performance of the fenestration system, such as wind load and water penetration.
  
  

Conclusion:

In summary, the Window Wall, Curtain Wall, and Storefront systems each have their own unique benefits and considerations. By carefully considering these factors, you can select the window system that will best meet the needs of your building design.
