USG Structural Panel Concrete Roof Deck Earns Approval from Factory Mutual (FM)

USG Corporation, Chicago, has received Factory Mutual Approval for its USG Structural Panel Concrete Roof Deck.


Factory Mutual (FM) Global is widely accepted as the leading organization that sets the industry standard with a rigorous testing process for select commercial building products. An approval from FM assures contractors and building owners that the product performs to the highest standards for safety. It also verifies a product’s contribution to maintaining a structure’s integrity, keeping the occupants and the interior content safe in the event of a natural hazard or fire.


USG Structural Panel Concrete Roof Deck is the first and only FM approved noncombustible structural panel sheathing in accordance with FM Standard 4472 for use in low-slope roof systems. In addition, it meets the FM 4475 requirements for steep-slope roof systems and is the first structural panel roof deck sheathing to meet the ASTM E136-16 fire reaction criteria.
