ArmorWall Fire-Rated Structural Insulated Sheathing™ is a building enclosure system commonly referred to as a Structural Insulated Sheathing (SIS) panel.
What is ArmorWall Made Of?
ArmorWall utilizes a 1/2″ layer of Magnesium Oxide (MgO) sheathing on the exterior face of the panel due to its high performance in fire resistance. Magnesium is present in large quantities all over the planet, where it is the eighth most abundant mineral on Earth. Magnesium Oxide is similar to gypsum compounds that design teams are accustomed to using for many years.
By replacing common gypsum and cementitious compounds that are commonly found in other construction materials with Magnesium Oxide, ArmorWall delivers top of the line fire-resistance, durability, and strength. This, combined with proprietary scrim formulations, creates a structural sheathing board that is unmatched in many of today’s performance categories.
Poured Polyurethane Insulation
MaxLife’s industry innovation does not stop there. From our beginning, we understood the contribution to the difficulty and labor from required continuous insulation compliance and the multiple steps required to assemble the commercial wall. MaxLife developed another proprietary formula of a poured polyurethane (PUR) insulation layer.
As a true continuous insulation that isn’t broken other than the fasteners and mechanical penetrations, ArmorWall meets the definition in ASHRAE 90.1 for continuous insulation (ci), which few products and assemblies can match.

What is ArmorWall's Compatibility?
A prominent concern with traditional components is the attachment of claddings and veneers to the wall assembly once several inches of insulation has been attached to the exterior stud face. Due to ArmorWall’s structural strength, it allows direct attachment of cladding to the component layers of the sheathing and no longer require attachment back to the stud frame assembly or substrate. Because there is no requirement, cladding can be mechanically fastened to any location on the exterior Magnesium Oxide sheathing of the ArmorWall panel.
