Product Description:

ArmorWall Structural Insulated SheathingSymmetrical Panel (SP) Vapor Permeable (VP) was launched to enable architects to pursue previously unattainable design features through its industry-leading structural strength, durability, continuous insulation properties, and fire, air and water-resistant capabilities.  

ArmorWall SP VP arrives to the job site with a factory-applied vapor permeable coating that makes it an excellent choice for most multifamily and commercial buildings.  Based on the project needs and architectural specifications, ArmorWall SP VP can be delivered in various sizes and with various insulation thickness and R-value. 

The most unique feature of ArmorWall SP is its ability to provide a two-hour fire rated exterior wall assembly in one step.  Accordingly, it is a preferred solution for buildings in densely populated areas as well as high rise buildings where installers are able to work with single panels in place of several components.

Like our other products in the series, ArmorWall SP VP drastically reduces the number of installation revolutions around a building.  This helps to reduce costs and time to weather-in by weeks.

ArmorWall SP VP is unique due to its additional layer of sheathing, made of Magnesium Oxide (MgO), a natural mineral with fire resistance properties, on the interior face encompassing the rigid foam insulation.  The MgO layers replace the common sheathings (such as gypsum, plywood, etc.) and compounds found in other products that require additional coatings, time and cost. In short, ArmorWall SP VP saves time, saves money and results in a superior building enclosure system!

ArmorWall SP VP’s innovative properties allow projects to meet and exceed continuous insulation, building code and green certification programs faster and more cost effectively.  ArmorWall SP VP is manufactured in a near zero waste manufacturing plant in North Carolina.

ArmorWall SP VP is the Best Solution for These Situations:

  • Buildings or specific wall areas that require a fire-rated wall assembly.
  • Projects with thinner walls that require fire ratings.
  • Projects with plenum spaces.
  • Core and shell buildings.
  • High rise buildings.
  • High velocity wind zones.
  • Job sites with minimum lay down space or short timelines.

What Makes ArmorWall SP VP Unique?

  • ArmorWall SP VP is one of very few composite single step materials that offer a 2-hour fire rated wall assembly.
  • It is designed to be the same depth as other products in the ArmorWall series allowing for seamless integration in wall assemblies.
  • It is an excellent solution for high rise buildings where installers can work with single panels in place of several components.

Project Highlights Featuring ArmorWall SP VP:

ArmorWall SP VP was used on the Pinnacle Cardiovascular Associates Medical Facility in Opelika, AL. Rendering courtesy of TRO Jung|Brannen.
This medical office building will be ore durable and energy efficient thanks to the ArmorWall SP VP installation.
The ArmorWall SP VP installation went very quickly, helping the project team reduce the project schedule by several weeks.

Know the Advantages of ArmorWall:

NFPA 285 Approved

Fully passed the NFPA 285 on its own without a required cladding on the front. This allows most UL tested, listed, and approved exterior finishes to qualify as part of the complete wall assembly.

Fusion Technology

Panel is manufactured using patented fusion technology bestowing unique properties to ArmorWall SP. Lamination not being party to the process allows a smooth foam backing.

Structural Sheathing

Thanks to the fusion technology and the elements of which ArmorWall is comprised, the structural strength of the panel allows direct attachment for cladding to the panel without the requirement of pin-pointing the studs.

Thermal Control Layer

The insulating layer of high density foam insulation is fused to the structural sheathing element which provides ease of use when conforming to the continuous insulation requirements in evolving building codes. The thermal layer is offered in a few standard thicknesses to meet the project required R-Values.

Panelized Construction

ArmorWall is ideal for handling the stress of factory-built wall assembly manufacturing process, including movement within the facility, deflection during transportation, and racking during wall erection. Self-adhered membranes have tremendous adhesion to the ArmorWall surface.

Mold and Mildew Resistant

No paper facings exist within the assembly to promote any biological growth.
