DuPont™ ArmorWall™ SP Plus Fire-Rated Structural Insulated Sheathing
5-in-1 Composite Panel for DuPont™ ArmorWall™ System (2-Hour Fire-Rated)
<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, receiving a two-hour fire resistant rating. This rating is twice that of our standard ArmorWall™ Plus panels. 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, makes <b>ArmorWall™ SP Plus FR SIS</b> twice as fire-resistant as 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 "dried-in," 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.

2ArmorWall™ SP Plus FR SIS is self-sealing around cladding attachment fasteners
3ArmorWall™ SP 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.
