Why is it important for curtain walls to be tested against fire resistance?

Testing curtain walls for fire resistance is critical primarily to ensure compliance with building code regulations. Building codes are established to safeguard public safety and minimize the hazards associated with fire, including the spread of flames and toxic smoke. Through rigorous testing, manufacturers can verify that curtain walls will perform adequately under fire exposure conditions, contributing to the overall fire safety strategy of a building. This ensures that structural integrity is maintained and that occupants have adequate time to evacuate in the event of a fire.

While cost-effectiveness, aesthetic qualities, and structural weight are important factors in the design and construction of buildings, they are not the primary reasons for testing curtain walls for fire resistance. Compliance with building codes is essential for legal approval and operational safety, making it the most crucial aspect of this inquiry.
