FGIA’s Updated Standard for Thermal Cycling Effects Evaluation Now Available

FGIA has recently updated AAMA 501.5-23, Test Method for Serviceability of Exterior Fenestration After Thermal Cycling, which outlines the standard laboratory procedure for evaluating the effects of thermal cycling on large exterior fenestration components and cladding. This AAMA Accredited Independent Laboratory procedure is available for purchase in the FGIA online store.

According to Steve Fronek, Chair of the Test Method for Thermal Cycling of Exterior Wall Review Task Group, the updated thermal cycling test method is aligned with the recently published AAMA 501.9 surface temperature assessment for condensation evaluation. Additionally, the cycling protocol based on exterior ambient air temperature is more-repeatable and representative, and glass breakage and noise associated with wall systems’ expansion and contraction have been addressed in detail.

This updated method evaluates the permanent damage caused by thermal cycling and can be used in conjunction with other test methods listed in AAMA 501 or as a standalone evaluation.

To purchase AAMA 501.5-23, as well as other AAMA documents available from FGIA, visit the online store at a discounted member rate of $20 or a non-member price of $60. For more information about FGIA and its activities, please visit FGIAonline.org.
