Wall System

         DuPont™ Performance Building Solutions has announced the addition of DuPont ArmorWall Systems to its innovative product portfolio.  The premium performance exterior commercial wall solution is a five-in-one system incorporating five traditional building enclosure elements into a single panel product: structural sheathing, fire-resistance, air-resistive and water-resistive barriers, and a high-performance continuous insulation layer.

         The additions of DuPont ArmorWall™ Plus Fire-Rated (FR) Structural Insulated Sheathing™ (SIS) and DuPont ArmorWall SP Plus Fire-Rated Structural Insulated Sheathing are the latest DuPont products to join the impressive portfolio of proven, compatible, and market-leading brands that protect all six sides of the building envelope.  DuPont acquired MaxLife Industries’ ArmorWall business, including the ArmorWall brand, patented technology, and manufacturing facility in late 2021.

         Both ArmorWall Plus FR SIS and ArmorWall SP Plus FR SIS utilize patented Fusion Technology to fuse the fire-resistant Magnesium Oxide (MgO) structural sheathing layer to the high-performance poured polyurethane insulation layer, which creates an ideal substrate for many types of cladding attachment.  Additionally, all panels arrive at the jobsite with a factory-applied, high-quality air and water-resistive barrier that eliminates the need for additional field-applied coatings or wraps.  The systems are available with either ArmorWall Plus FR SIS or ArmorWall SP Plus FR SIS as the panel component and include ArmorBoard Plus Structural Sheathing Returns and ArmorSeal accessories as part of the complete system.

         ArmorWall SP Plus FR SIS includes an additional layer of MgO sheathing on the interior face, encompassing the polyurethane foam insulation.  This addition makes ArmorWall SP Plus FR SIS a two-hour fire-rated assembly, benefiting multi-family projects and buildings in high density areas.  Furthermore, both ArmorWall Plus FR SIS and ArmorWall SP Plus FR SIS pass NFPA 285 testing as part of DuPont ArmorWall Systems complete wall assemblies.  Both ArmorWall Plus FR SIS and ArmorWall SP Plus FR SIS are ICC-ES listed.  The DuPont ArmorWall Systems have undergone rigorous testing and allow projects to meet continuous insulation requirements, building codes, and the tight timelines of construction schedules faster and more cost-effectively.
