DuPont™ ArmorWall Plus Fire-Rated (FR) Structural Insulated Sheathing™ (SIS)

Cuts Like Wood. Burns Like Concrete.

DuPont™ ArmorWall Plus Fire-Rated (FR) Structural Insulated Sheathing™ (SIS) incorporates no less than four traditional building enclosure systems into a single panel product: structural sheathing, fire-resistance, an air and water-resistive barrier, and a high-performance continuous insulation layer. The four-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.

Fusion Technology

Our patented Fusion Technology allows us to do things that were thought impossible in recent years. Our revolutionary process and materials are constantly constructing better buildings and safer environments while saving time and money on jobsites across the globe.

Passes NFPA 285 Testing

ArmorWall Plus FR SIS™ passes 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 ArmorWall Plus FR SIS™ as part of a complete wall assembly.

Structural Sheathing and Cladding Support

We fuse Magnesium Oxide (MgO) sheathing onto the exterior face of ArmorWall Plus FR SIS™ 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, ArmorWall Plus FR SIS™ has been tested to support loads equivalent to most building cladding finishes, with minimal creep while under load.

Continuous Insulation

ArmorWall Plus FR SIS™ has a high-performance, poured polyurethane insulation layer fused to our sheathing using our 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 (R10, R15, and R21).

Weather-Resistive Barrier

ArmorWall Plus FR SIS™ passes 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.

Air-Resistive Barrier

Once properly sealed using ArmorSeal Sealant at all seams and sheathing fasteners,ArmorWall Plus FR SIS™ meets the IBC and ASTM E283 requirements for an air barrier assembly without the need for additional materials.

Panelization

ArmorWall Plus FR SIS™ offers a single pre-fabricated system that can be delivered on-site and installed in days, not weeks. ArmorWall Plus FR SIS™ reduces the common stresses of factory-built wall assembly manufacturing, including movement within the facility, deflection during transportation, and racking during wall erection.
