, Voluntary Practice for Assessment of Frame Deflection When Using Propellant Expanding Foam Sealants for Air-Sealing Rough Openings of Fenestration Installations, an FGIA document, is now available for purchase in the FGIA online store.

“As aerosol foam sealants grow in popularity and become a ubiquitous part of fenestration product installation, AAMA 812 is an essential document is an essential read for site managers, architects, engineers and manufacturers,” said Michael J. Engel (), Chair of the FGIA Assessment of Frame Deflection from Expanding Materials Task Group. “Such foams need to be tested and maintain strict performance metrics specifically to meet the needs fenestration products. Understanding this specification helps ensure the understanding of the processes to qualify these products and will aid the construction and manufacturing industry make the best decisions for fenestration installation.”

In the past, aerosol foams were sometimes linked to frame deflection in fenestration products due to improper use or the use of foams not designed for that application. Today, aerosol foams are available that are specifically formulated for use with fenestration products. These newer formulations are designed to minimize pressure during curing, reduce the risk of deflection, and maintain dimensional stability after curing.

, 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.
