ArmorWall™ Plus FR SIS
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 factory-applied, high quality air and water-resistive barrier.. Once seams and fasteners have been sealed the enclosure may be considered “dried-in”, allowing interior construction to commence regardless of final exterior finish status. 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.
