DuPont™ ArmorWall Systems pass NFPA 285 testing without the additive protection of an exterior cladding on the front for the full duration of the test. This allows for engineering judgements to be made for most NFPA 285 tested and approved exterior finishes when used with DuPont™ ArmorWall Systems as part of a complete wall assembly.

We fuse Magnesium Oxide (MgO) sheathing onto the exterior face of DuPont™ ArmorWall Systems panels in order to gain high strength and durability not commonly found today in traditional building enclosure products. With its ability to move the stud face to the exterior face of the sheathing, DuPont™ ArmorWall Systems have been tested to support loads equivalent to most building cladding finishes, with minimal creep while under load.

DuPont™ ArmorWall Systems have a high-performance, poured polyurethane insulation layer fused to the sheathing layer using patented Fusion Technology, which provides an easy way to comply with continuous insulation (ci) requirements in building codes. The thermal layer is offered in three standard thicknesses and R-Values for both ArmorWall Plus FR SIS™ and ArmorWall SP Plus FR SIS.

DuPont™ ArmorWall Systems pass ASTM E331 as a water-resistive barrier for pressure totaling two hours, and complies fully with Chapter 14 of the International Building Code (IBC) for water-resistive barriers. Once the sheathing fasteners and seams have been sealed, the structure is considered weathered and dried-in and interior construction may commence.
