ArmorWall NP interior/exterior wall sheathing is a UL Classified and tested, high strength, fire resistant exterior insulated wall sheathing product, commonly referred to as an SIS (structural insulated sheathing) panel. MaxLife’s technology fuses a structural element to the exterior face of our fused insulation layer which modernizes the installation of commercial and residential wall assemblies. This innovation allows the designer to re-implement legacy design or frees them to wider creativity while maintaining wall construction speed, efficiency, and code compliance.

Amongst the factory-coated panels in the armorwall series of products, ArmorWall NP has an applied non-permeable water resistant barrier coating. Once seam and fasteners have been sealed the envelope may be considered “dried-in” allowing interior construction to commence regardless of final exterior finish status.

Like our other products in the series, ArmorWall NP requires just one installation revolution around a building in place of the traditional four, reducing costs and time to weather-in by weeks. Magnesium Oxide (MgO), a natural mineral with fire resistance properties, is fused onto the exterior face of each panel, replacing common gypsum and cementitious compounds that otherwise require additional coatings, time and cost. 

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

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 NP. 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.

Air Control Layer

When properly sealed using ArmorSeal Sealant application at all seams and fasteners, the factory coated panels meet the IBC requirements for an air barrier assembly without the need for additional materials.

Water Control Layer

Armorwall NP is factory-coated with a Non-Permeable water control layer.

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.
