Featuring a 1/2″ layer of Magnesium Oxide (MgO) sheathing on the exterior side, DuPont™ ArmorWall™ Plus Fire-Rated (FR) Structural Insulated Sheathing (SIS) arrives at the job site complete with a factory-applied, high quality air and water-resistive barrier on the exterior sheathing layer.
ArmorWall™ Plus FR SIS
DuPont™ ArmorWall™ Plus Fire-Rated (FR) Structural Insulated Sheathing (SIS) is an ICC listed, high strength, fire-resistant exterior insulated wall sheathing product. ArmorWall™ Plus FR SIS arrives at the job site complete with a high quality air and water-resistive barrier on the exterior.
Due to the high strength and rigidness of the structural sheathing, ArmorWall™ Plus FR SIS has the ability to move the stud face to the exterior face of the sheathing and has been tested to support loads equivalent to most building cladding finishes, with minimal creep while under load.
In addition, the unique coating on ArmorWall™ Plus FR SIS offers industry-leading exterior adhesion performance and compatibility with tapes, sealants, and other materials, including the ArmorSeal line of products.
The ArmorSeal line of products can be installed and cured in harsh weather conditions, with overall proven functionality of the panel in all outdoor environments
Once seam and fasteners have been sealed the enclosure may be considered “dried-in”, allowing interior construction to commence regardless of final exterior finish status.
Having undergone rigorous testing, ArmorWall™ Plus FR SIS allows projects to meet continuous insulation (ci), building codes, and construction schedules faster and cost effectively.
