Fire Barrier Coating

GAF Materials Corporation’s new FireOut Fire Barrier Coating provides UL Class A fire ratings when applied to combustible decks. It eliminates the need for recover boards or slip sheets, saving as much as 43 percent on installation, all according to the manufacturer.


The coating expands in the presence of heat or flame to form a protective insulation layer, and causes a chemical reaction that helps to extinguish the fire by blocking heat and oxygen.


The one-step application can be done using a roller, squeegee or airless sprayer, and the coating itself is less than 10 percent the weight of recover boards, according to the manufacturer.
