About ArmorWall Plus

ArmorWall Plus arrives at the job site complete with a proprietary air and water-resistive barrier on the exterior, the first coating made exclusively for Magnesium Oxide (MgO).

Once seam and fasteners have been sealed the enclosure may be considered “dried-in”, allowing interior construction to commence regardless of final exterior finish status.

Offers industry-leading exterior adhesion performance and compatibility with tapes, sealants, and other materials

ArmorSeal line of products can be installed and cured in harsh weather conditions, with overall proven functionality of the panel in all outdoor environments

Cladding no longer requires attachment back to the stud frame assembly or other substrates due to the flat and rigid surface of the exterior structural sheathing

Meets and exceeds continuous insulation (ci), building code, and green certification programs

ArmorWall Plus Passes Testing For:

Passes NFPA 285 testing without the additive protection of an exterior cladding on the front for the full duration of the test

Passes ASTM E119/UL 263 testing using the same wall panels for the full two hours, something many other wall assemblies cannot do
