Standard for aerosol foams used in fenestration installation updated

The Fenestration and Glazing Industry Alliance (FGIA) updated a specification describing the use of aerosol foams developed specifically for application with fenestration products.

AAMA 812-25, “Voluntary Practice for Assessment of Frame Deflection When Using Propellant Expanding Foam Sealants for Air-Sealing Rough Openings of Fenestration Installations” is 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 for site managers, architects, engineers and manufacturers,” said Michael J. Engel (Henkel Corporation), 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 to make the best decisions for fenestration installation.”

In the past, aerosol foams were sometimes linked to frame deflection in fenestration products when used improperly or when foams not designed for that application were used. 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.
