, Fenestration Sealants Guide for Windows, Window Walls and Curtain Walls, an FGIA standard, is the first update to this document, originally published in 2009.

“AAMA 851 is an excellent resource in helping identify areas of consideration when selecting sealant systems,” said Steve Altum (), Chair of the Fenestration Sealant Application Guide Task Group. “Choosing the right sealant system for the right application is critical to building or manufacturing products that can meet today’s industry standards and requirements.”

Altum added that understanding proper joint design and the end performance requirements are critical to meeting intended design loads and maintaining quality, long lasting products.

“While the individual manufacturer of sealant choice should always be consulted for specific performance attributes, this guide will help to identify some of the key considerations such as substrates, environmental, joint movements and compatibility of components used in the overall system design,” said Altum. “It will be especially insightful for those new to the industry.”

AAMA 851 reviews the type of sealants currently in use and their application following accepted standard practices. It encompasses both field and factory applications.
