DuPont™ ArmorWall Plus Fire-Rated (FR) Structural Insulated Sheathing™ (SIS) is an ICC listed, high strength, fire-resistant exterior wall sheathing product. ArmorWall Plus FR SIS™ offers a scientifically engineered, factory-applied air and water-resistive barrier on the exterior sheathing.

ArmorWall Plus FR SIS™ incorporates five traditional building enclosure elements into a single panel product: structural sheathing, fire-resistance, air barrier, water-resistive barrier, and a high-performance continuous insulation layer. The five-in-one system of ArmorWall Plus FR SIS™ can replace several traditional individual components that, on their own, add cost, labor and complexity to a project.
