[1]The Fenestration and Glazing Industry Alliance (FGIA) released AAMA 517-25, Specification for Air/Water Penetration Resistance, and Structural Load Performance of Multi-Track Doors and Windows. The new specification is applicable for testing and rating horizontal sliding windows and sliding doors based on the sash/panel size and interlocking conditions present in tested samples.

The document is intended to supplement AAMA/WDMA/CSA 101/I.S.2/A440, North American Fenestration Standard/Specification for Windows, Doors, and Skylights (NAFS). AAMA 517 supplements laboratory testing to NAFS for air, water, and structural performance.

Jason Seals, FGIA staff liaison for FGIA’s multi-track or multi-panel sliding systems task group, says, “NAFS currently limits the ratings assigned to windows and doors to the maximum tested frame size. This can be problematic for testing products that are designed to incorporate a large number of sash/panels enclosing large openings.”

Testing these products at the maximum number of sash/panels can be impractical, Seals says. AAMA 517 users may qualify these products using a representative number of sash/panels.
