Anyone have any experience with Armorwall Structural Insulated Sheathing Panels by Maxlife Industries?
Pros and/or cons.
Thx
I have it going up on 3 buildings currently and specified for two others.
It’s a great solution for attaching high fastener count exterior materials to the building like formed metal panels, especially smaller shingles. The are still ramping up production and the installers are getting used to working with the product.
Talked with one of our local installers and the estimators like it since it simplifies sequencing and components.
Thanks for responding Brian. On your projects, are they vapor permeable in rain screen applications?
Mostly, yes. On one project we are using Dorken Delta Dry-Lathe over Armorwall VP to adhere exterior tile/manufactured stone.
The VP only really helps dry out the magnesium oxide board where penetrated since the Urethane foam is a air/water/vapor barrier itself.
Ron, there have been issues with “non-combustible” Magnesium Oxide panels actually being combustible when tested by 3rd parties. Although I do see that Armorwall has a UL certification for NFPA 285 testing on their website, it does not indicate what actual assembly or testing was performed. I suggest you look deeper into this.
Edward, I’ve heard of that as being an issue with some imported products.
I spoke with my ArmorWall rep about fire-rated assemblies, not just NFPA 285 compliance, and received this link in case it’s helpful:

I don’t know enough about the product or the technology. Perhaps their configuration protects the magnesium oxide from combustion sources.
Please let me know if you’d like contact info for the local rep in my region.
Thanks, guys.
Brian:
How did you deal with the air barriers on your various projects? …sheet or liquid or the panels themselves (w/taped joints)? I’m mostly interested in the product/methodology of the transition to the roof deck. Thx.
