DuPont™ ArmorWall™ Plus and ArmorWall™ SP Plus Fire-Rated (FR) Structural Insulated Sheathing (SIS) can be exposed for up to 180 days to UV. After 180 days, the exposed panels need to be protected from further exposure. A DuPont Technical representative may, upon request, conduct a jobsite observation of the exposed product to consider an extension for panel UV exposure.

The ArmorWall™ System provides a complete structural attachment surface, allowing cladding to be attached anywhere along the face of the panels without fastening back to framing. There are not restrictions based on cladding weight and ESL 1543 provides cladding fastener structural performance for design by a qualified professional and prescriptive cladding attachment opportunities based on cladding weight.

The weight for different thicknesses in of a standard ArmorWall™ SP Plus FR SIS panel is as follows:
2 ¾" Panel (R11): 185 lbs.
3 ¾" Panel (R17): 199 lbs.
4 ¼" Panel (R21): 203 lbs.
For more information on Panel Properties, please refer to the ArmorWall™ Product Information Sheets

The allowed limit for gaps in open joint rainscreen systems is up to 3/8" in width.

Tools commonly found on construction projects, such as circular saws and reciprocating saws can be used. Refer to the ArmorWall™ Installation Manual for cutting and installation instructions for the ArmorWall™ System. When cutting ArmorWall™ panels, DuPont recommends a dust mask, protective gloves, and eye protection. Additional respiratory protection is needed in areas with limited ventilation.

All ArmorWall™ FR SIS panels are 4′ x 8′.For more information, please refer to the ArmorWall™ Product Information Sheets.

The strength of an ArmorWall™ FR SIS panel is due to our patented Fusion Technology and rigid component facing. These innovations provide our panels with higher structural strength compared to similar products in the marketplace, most of which are manufactured by laminating (similar to gluing) the structural and insulation layers together. Delamination may occurs when certain types of panels are exposed to moisture, heat or load.

The products listed do not release or otherwise result in exposure to a hazardous chemical under the intended conditions of use and meet all other listed requirements of an article. Therefore, these products meet the global definitions of articles which do not require SDS creation or distribution.

Yes, the ArmorWall™ System complies with NFPA 285 standards testing with multiple claddings and assemblies. Please refer to ICC ESL-1442 for additional information. The report listing can be found here

For steel studs, each screw must penetrate the frame with at minimum three threads showing beyond the metal surface. For wood studs and concrete, each screw must penetrate the substrate by 1" minimum of full fastener threads excluding drill tip and thread taper.
