FGIA Document Supplements NAFS for Air, Water, Structural Performance Testing of Multi-track Doors, Windows

The Fenestration and Glazing Industry Alliance (FGIA) has released a new specification applicable for use in testing and rating horizontal sliding windows and sliding doors based upon the sash/panel size and interlocking conditions present in the tested samples. AAMA 517-25, Specification for Air/Water Penetration Resistance, and Structural Load Performance of Multi-Track Doors and Windows, a new FGIA document, is now available for purchase in the FGIA online store.

Document details

This new document is intended to be used as a supplement to 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.

AAMA 517-25, as well as other documents available from FGIA, may be purchased from the online store at the discounted member rate of $25 or the non-member price of $70.

What FGIA says

“NAFS currently limits the ratings assigned to windows and doors to the maximum tested frame size,” says Jason Seals, FGIA staff liaison for the FGIA Multi-Track or Multi-Panel Sliding Systems Task Group. “This can be problematic for testing products that are designed to incorporate a large number of sash/panels enclosing large openings.” Because testing these products at the maximum number of sash/panels can be impractical, explained Seals, AAMA 517 users may qualify these products using a representative number of sash/panels.
