FS84 is fully tested and has a rating ranging from Class A to 30 minutes to meet building codes domestically, internationally, and for the Wildfire Urban Interface. When Flame Seal 84 is exposed to fire or extreme heat, a protective layer of Carbon Foam develops and prevents the fire and heat from transferring to the substrate.

For best application Flame Seal recommends using an airless sprayer, please see application guide for more information.
