AAMA TIR-A20-23 offers a technical review of key issues, including heat buildup, load sharing, aesthetics and cavity venting strategies.

The Fenestration and Glazing Industry Alliance (FGIA) unveiled a new technical report discussing best practices for system design of spandrel areas. This includes the use of conventional spandrel glass and vision glass together with shadow box panels.

AAMA TIR-A20-23, Glazed Spandrel and Shadow Box Design Considerations, provides an overview of design considerations for glazed spandrel infills, including both spandrel glass and shadow boxes, as employed in conventional curtainwall, window wall and other fenestration systems, whether stick-built or unitized.

“Glazed spandrels are often used as opaque areas of the building envelope at floor slabs, columns and immediately below roof areas,” explains Steven DeSutter, FGIA CurtainWall/Window Wall Spandrel Review task group member. “Whether incorporating conventional opacified spandrel glass or shadow box assemblies, unique design considerations apply.”

DeSutter adds that AAMA TIR-A20-23 offers a technical review of key issues, including heat buildup, load sharing, aesthetics and cavity venting strategies. The report also provides a baseline for the ongoing development of test methods to verify spandrel performance.
