Pyro-Guard® and Exterior Fire-X® lumber and plywood are produced for interior and weather-exposed applications, respectively, and have a flame-spread rating of 25 or less, even after 30 minutes of test time. Both products are clearly labeled and carry the UL® mark. Pyro-Guard® and Exterior Fire-X® lumber and plywood are tested in accordance with procedures outlined in the International Building Code and NFPA 703. Pyro-Guard® is accepted under ESR-1791 as meeting the requirements of the International Building Code, National Building Code, Standard Building Code, and the Uniform Building Code.
Pyro-Guard® and Exterior Fire-X® are recognized for applications where noncombustible materials are required in buildings. Examples are nonbearing partitions, nonbearing exterior walls, roof assemblies, platforms, canopies, exterior architectural trim and veneers, exterior balconies, exterior-bearing walls in joisted-masonry and heavy timber construction, and increasingly for decks in wildfire prone areas.
