Frequently Asked Questions (FAQ's)
ArmorWall Fire-Rated Structural Insulated Sheathing™ (SIS) Panels
The strength of ArmorWall is due to MaxLife Industries’ patented Fusion Technology and rigid component facing. These innovations provide our panels with nearly twice the strength of similar products in the marketplace, most of which are manufacturing by laminating (similar to glueing) the structural and insulation layers together. Delamination occurs when certain types of panels are exposed to moisture, heat or load.
ArmorWall panels also:
- Reduce cross-bracing of both wood and steel framing
- Offer industry-leading pull-out strength
- Have Dead Load Anchor Testing that yield very strong results
- Can be used in high velocity wind and hurricane zones
- Can be used in seismic sensitive areas
You can see more information on ArmorWall’s strength and durability in the Documentation section of our website.
Standard ArmorWall panels are 4′ x 8′. Special order panels are available in 4’x 10′ and other sizes. Please contact Customer Service for more information.
Yes, the results are better than common OSB, and similar to 5/8” plywood and wood sheathing. This allows ArmorWall to be used in a structural wall element as required by the Structural Engineer for shear and wind requirements. Please refer to our Installation Guides in the Documentation page for more information.
For detailing windows with ArmorWall, refer to our Installation Manuals (pg. 21-23) in the Documentation page.
Currently MaxLife Industries offers a ten-year material warranty on ArmorWall panels that is non-prorated over the period and limited to the cost of the materials and replacement.

MaxLife prides itself on fast delivery for all customer orders, no matter the project need. We offer two primary methods for purchase and delivery of ArmorWall panels and accessories:
- Purchase from an area Product Representative with direct shipment from our manufacturing plant in Salisbury, North Carolina. Under normal market conditions, lead times are generally two to four weeks to receive the material.
- Purchase and delivery from a regional or national Distribution Partner. Lead times may be shorter in some areas from Distribution Partners that stock ArmorWall panels and accessories locally.
Visit our Where To Buy page for contact information on our area Product Representatives and Distribution Partners.
Yes; it has passed the required ASTM testing and performs as such during our testing procedures.
Yes, approved fasteners are required when installing ArmorWall to ensure satisfactory installation and maintain our ten-year system warranty.
If an Installer were to use non-approved fasteners such as non-exterior grade screws, the wall system would be susceptible to the elements such as moisture and freezing temperatures, causing it to corrode and rust. When you use ArmorWall tested and approved exterior grade screws, you don’t have this issue. All sheathing and cladding attachment screws are Tri-Seal coated by Concealor, providing long-term resistance to corrosion and salt water spray.
Approved fasteners may be purchased directly from MaxLife or from Triangle Fastener.
No, seal only the fasteners that attach the ArmorWall panels to steel, wood, or concrete framing in order to ensure a continuous seal.
Yes, it’s true! Thanks to our patented Fusion Technology and the elements of which ArmorWall Fire-Rated Structural Insulated Sheathing is comprised, the structural strength of the panel allows direct attachment of cladding to the panel without the requirement of pin-pointing the studs beyond. View our Documentation page for more information on cladding and ArmorWall.
There are several key points which differentiate the ArmorWall Fire-Rated Structural Insulated Sheathing system™ from the Magnesium Oxide board implementation in certain articles published about MgO board.
MaxLife Industries employs rigorous quality control and assurance testing throughout the manufacturing of the MgO boards used, which results in a much lower level of Chlorides within the chemistry. The MgO implementation within the final product itself is vastly different from that which was observed in the construction assembly in said articles. In addition, the tested and approved coated system fasteners are Marine Grade 1000+ hour exposure rated, dissuading corrosion and degradation.
If you would like further information, we encourage you to reach out to your local sales representative.
Yes, standard ArmorWall panels have been tested and have achieved ratings for up to one (1) hour assemblies that are located within the UL Fire Resistance Design listing catalog. ArmorWall Symmetrical Panel (SP) and SP Plus have been tested and achieved ratings for up to two (2) hour assemblies.
Several common assemblies can be found within the ArmorWall Rated Assemblies Handbook.
Yes, ArmorWall fully passed NFPA 285 standards testing on its own – without a required cladding on the front – which is incredibly unique in the building materials industry. In fact, ArmorWall was tested without any cladding placed over the sheathing at all for the full duration of the test.
Being a NFPA 285 Approved Structural Insulated Sheathing, ArmorWall carries many properties that are unmatched within the marketplace today, and not found in typical commercial gypsum assemblies.

Test reports are available per request; you can also find all of the data and results placed in the data sheets in the Documentation page. The testing was completed by certified third party labs and organizations as required by ICC.
MaxLife Industries is under the UL audit program as well as our raw materials plants abroad. The ArmorWall brand of products are also UL Classified, which is very unique.
The results speak for themselves and are proudly displayed within the UL Product IQ site under R39485. You may also click here to download our UL Certification and report. Our NFPA rating allows most UL tested, listed, and approved exterior finishes to qualify as part of the complete wall assembly. This includes Type I, II, and III buildings. That information can be found within our NFPA approval summary pages.
All above-grade ArmorWall panels (this excludes our Below Grade (BG) product) can be exposed for 180 days to UV. ArmorWall BG may only be exposed for thirty (30) days maximum.
