Fortress Adds FR-700 Structural Fire Retardant to the Forest Service's Qualified Products List (QPL)

Rocklin, CA. – FORTRESS NORTH AMERICA announces “Fully Qualified” status upgrade of its structural fire retardant, FR-700, on the U.S. Forest Service’s Qualified Products List (QPL).

Fortress FR-700 is the first commercial long-term fire retardant product that’s purpose-built for direct structural application. FR-700 has unique chemical properties that enable it to adhere to vertical surfaces, forming a durable coating that shields structures from fire. Now fully qualified, FR-700 adds another tool to the wildfire defense toolkit for homeowners, commercial property owners, municipalities, and utility companies in fire-prone areas.

The approval of FR-700 expands FORTRESS’ portfolio of ground-applied retardants. By partnering with Fortress, property owners are now able to construct durable wildfire perimeters around their property with FR-600 ground retardant while also adding an additional layer of protection to their most valued assets with FR-700 structural retardant.

“FR-700 is a particularly important new product as it is the first of its kind. It will be used to protect structures and help property owners and insurers better manage their wildfire risk,” says Robert Burnham, CEO of FORTRESS NORTH AMERICA.

FR-700 is the 4th long-term fire retardant product from FORTRESS that has achieved “Fully Qualified” status on the Qualified Products List. Aerial retardants, FR-100 dry powder and FR-200 liquid concentrate, were fully qualified in December 2022, establishing FORTRESS’ innovative magnesium chloride technology as a mainstay in the fire retardant industry.
