DuPont™ ArmorWall™ Plus Fire-Rated Structural Insulated Sheathing

5-in-1 Composite Panel for DuPont™ ArmorWall™ System (1-Hour Fire-Rated)

<br><b>DuPont™ ArmorWall™ Plus Fire-Rated (FR) Structural Insulated Sheathing (SIS)</b> is an ICC listed (ESL-1302, ESL-1306, ESL-1442, ESL-1536, and ESL-1543), high strength, fire-resistant exterior wall sheathing product. <b>ArmorWall™ Plus FR SIS</b> 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. <br><br>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 <b>five-in-one</b> system of <b>ArmorWall™ Plus FR SIS</b> can replace several traditional individual components, making it a cost-saving and labor-reducing option compared to traditional, individual components.
 
 
 
 
 
 

Features & Benefits 

 
 
 

Air-and-Water-Resistive-Barrier.png
Air and Water-Resistive Barrier
  • Arrives complete to the jobsite with a factory-applied, high quality air and water-resistive barrier on the exterior sheathing.
  • Coating offers industry-leading exterior adhesion performance and compatibility with tapes, sealants, and other materials.
Cladding-Attachment-Support.png
Cladding Attachment Support
  • Capable of handling many different claddings, attachments, and hangers, all of which attach directly into the component layers of the sheathing and no longer require attachment back to the stud frame or substrate assemblies.
Fusion-Technology.png
Fusion Technology
  • High-performance, poured polyurethane insulation layer fused to our sheathing, which provides an easy way to comply with continuous insulation requirements in building codes.
  • Utilizes a 1/2" layer of Magnesium Oxide (MgO) sheathing on the exterior and interior face, providing top of the line fire-resistance, durability, and strength.
Install-in-Harsh-Weather.png
Install in Harsh Weather
  • Can be installed and cured in harsh weather conditions, with overall proven functionality of the panel in all outdoor environments.
  • Can be exposed to weather for up to 180 days.

2ArmorWall™ Plus FR SIS is self-sealing around cladding attachment fasteners.

3ArmorWall™ Plus FR SIS passes NFPA 285 attached directly to the stud framing allowing most cladding installed to its exterior as inclusive to the NFPA 285 approved assembly

4Fastener data reflects attachment to the panel not attachment to structure.
