The Xi Wall is our most advanced wall system available. Superior Walls are steel reinforced concrete wall panels that create a permanent barrier against sidewall water penetration. The Xi Wall features 2-1/2-inches of continuous DOW® Styrofoam for superior warmth and energy efficiency in the home.

The foundation wall is insulated throughout, including the corners, studs and bond beams. Special engineering from Superior Walls makes each wall thermally isolated and insulated from exterior elements, resulting in a superior product for below-ground foundation system installation.

Deeper Background. The Superior Walls Xi™ foundation system forms a concrete cavity wall panel with concrete studs at 24 inches on center attached at the top and bottom with bond beams. The entire assembly is faced with an integral concrete face shell. The wall is reinforced with rebar and polypropylene fibers providing additional structural strength. In addition, the concrete studs are cast with holes for wiring and factory galvanized steel on each stud for interior finishing. Superior Walls are available in a variety of standard heights and custom lengths to suit your project. The maximum axial load (uniform house weight) for this product is 5500 pounds per linear foot. Special point loads up to 50,000 pounds can be accommodated.

Superior strength is guaranteed in each panel based on the 5,000+ PSI concrete that is used during construction of the panel. The concrete used in Superior Walls products provides lifetime protection against freeze/thaw cycles and water vapor transmission while the urethane sealant used between panels provides superior protection against sidewall water penetration. No additional damp proofing materials are required.

The high-strength low-water concrete mix is poured for solid structural integrity and reinforced with steel rebar and polypropylene fibers. Each Xi Wall panel also includes horizontal steel rebar inside top and bottom beams, vertical steel rebar inside each stud, steel-reinforced concrete studs and footer beams.

Rapid installation time - normally less than one day - allows builders to begin construction on the home the same day. Superior Walls panels are custom made for each home and are manufactured and delivered complete with built-in openings for windows and doors, pre-engineered access for wiring or small plumbing elements and with smart stud facings for easy drywall installation.

Deeper Background. The concrete used in Superior Walls provides protection against freeze/thaw cycles and water vapor transmission. The urethane sealant used between panels provides superior protection against water penetration. Therefore, no additional damp proofing materials are required in a properly installed Superior Walls foundation. The closed cell polystyrene material in the Dow Styrofoam® provides an effective vapor barrier for Superior Walls.

Deeper Background. Dow Styrofoam® exhibits the following surface burning characteristics: flame spread 5 and smoke developed 165. The Superior Wall system does not require the attachment of a 15 minute thermal barrier over the foam plastic as proven by UL 1715 tests.

Superior Walls is also an active member of many of the standards-writing industry organizations such as the American Concrete Institute, the National Precast Concrete Association (Member of the Building Products - Foundations Subcommittee), and the National Association of Home Builders (Member of CHBC).

As a third-party inspected, pre-engineered system, we view the building codes and Building Officials as valuable allies in our quest to maintain the integrity of our system.

• NAHB Green Approved Product by the NAHB Research Center
• Superior Walls Xi and R-5 Wall Systems are approved to receive up to 10 points toward certification under the National Green Building Standard practices:
• Practice 601.2 - 3 points - Structural systems/advanced framing techniques optimize material usage
• Practice 601.5 (1-3) - 4 points - Precut/preassembled components, panelized, or precast assemblies are utilized for a minimum of 90% of floor, wall, and/or roof system.
• Practice 607.1 - 3 points - Products containing fewer materials are used to achieve the same end-use requirements as conventional products.
• Practice 701.4.3.1 (1) - Mandatory - Insulation is installed in accordance with the manufacturer's instructions or local code. Mandatory for certification.
• Resource efficient, using up to 70% less concrete in a new home than conventional foundations. Stud facings eliminate the need for additional wood framing prior to interior finishing.
• Fewer materials help reduce the carbon footprint of the new home's construction process.

• Helps lower energy costs and reduce energy leakage.
• Helps improve indoor air quality.
• Provides increased living space in a comfortable setting.
• Adds to the resale value of the home.
