INCORPORATING ARCHITECTURAL LOUVERS

August 14, 2023

Unitized curtain wall systems provide a streamlined, cost-effective exterior envelope solution for modern building projects. Integrating architectural louvers into these unitized assemblies allows the curtain wall subcontractor to quickly install the large glass sections along with the louvers. This article covers key considerations when specifying louvers for unitized curtain walls.

Benefits of Combining Louvers and Unitized Curtain Walls

Installing louvers aligned with unitized panels enables:

  • Targeted ventilation without compromising weather resistance since louvers and curtain wall will have pre-engineered system components 

  • Enhanced facade aesthetics with horizontal or vertical banding or accents

  • Flexibility to use different louver styles and configurations such as a continuous horizontal blade, mullions, or a vertical louver

Louver Positioning Options

Louvers can be positioned:

  • Between vision glass within a unitized panel

  • As a full panel module within the curtain wall elevation

  • Below vision glass panels for fresh air intake

Various Installation Methods

Louvers are commonly integrated using structural silicone glazing with the louvers installed directly with silicone sealant. They can also be incorporated into sub-frames as part of a window wall system. Additionally, louvers can be pre-installed into packaged unitized panels.

Key Factors When Specifying Louvers

Considerations for louver selection:

  • Wind load resistance for project location

  • Blade configuration and or notching around mullions Water penetration and air performance requirements that are approved by the mechanical engineer

  • Desired aesthetics and finishes such as mitered outside corners

  • Integrated blank off at predetermined parts of the louver

Operational Choices

Getting louver sizing, assembly details and shop drawings right is crucial for successful integration with the surrounding unitized curtain wall. Engage an experienced manufacturer like Aire Renaissance early in the design process to ensure proper specification of louvers to fulfill ventilation needs without inhibiting installation or the curtain wall system warranty.

Combining thoughtfully placed louvers with unitized curtain walls results in high-performing building envelopes that are both functional and architecturally striking. Contact Aire Renaissance to explore louver solutions compatible with your curtain wall assemblies.
