DuPont™ ArmorWall™ SP Plus Fire-Rated Structural Insulated Sheathing

5-in-1 Composite Panel for DuPont™ ArmorWall™ System

<br /><b>DuPont™ ArmorWall™ SP Plus Fire-Rated (FR) Structural Insulated Sheathing (SIS)</b> is an exterior wall sheathing product that has undergone rigorous ICC testing, with up to a two-hour fire rated assembly achievable. The unique feature of <b>ArmorWall™ SP Plus FR SIS</b> is that in addition to having a Magnesium Oxide (MgO) Sheathing material layer on the exterior face, it has an added layer of MgO sheathing on the interior face, which encapsulates the rigid foam insulation. This additional layer of sheathing, made from a naturally occurring fire-resistant mineral, gives <b>ArmorWall™ SP Plus FR SIS</b> added fire-resistance versus the Plus version. <br /><br />It also provides a factory-applied, air and water-resistive barrier on both the exterior and interior sheathing, which once sealed, makes the enclosure &quot;dried-in,&quot; allowing for the commencement of interior construction, irrespective of the final exterior finish's status. <b>ArmorWall™ SP Plus FR SIS</b> is an all-in-one panel product that combines five traditional building enclosure elements: structural sheathing, fire-resistance, air barrier, water-resistive barrier, and a high-performance continuous insulation layer, 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.
