DuPont ArmorWall

Cuts Like Wood. Burns Like Concrete.™

One Install + One Warranty

DuPont™ ArmorWall Fire-Rated (FR) Structural Insulated Sheathing™ is an innovative building enclosure system used in commercial and multifamily buildings that combines four traditional enclosure components into one, reducing costs and time to weather-in by weeks.

  • Utilizes Magnesium Oxide (MgO) sheathing on the exterior face of ArmorWall in order to gain attributes not commonly found today, including direct attachment of furring and cladding.
  • Its innovative properties allow projects to meet and exceed continuous insulation, building code and green certification programs faster and more cost-effectively.
  • The patented fusion technology consists of bonding the required continuous insulation layer to the developed sheathing layer to create a combined substrate that does not delaminate as seen with other common insulated sheathing materials.
  • Combining these two layers of MgO and polyurethane insulation has the ability to effectively move the structural face of the stud layer to the exterior face of the sheathing.
