Superior Walls XL-Wall Foundation System

The Xi wall has an insulated value of R-12.5 and utilizes 2.5 inches of Dow STYROFOAM built into the wall cavity for energy efficiency. Additional cavity insulation may be site-installed to maximize insulation up to a value of R-50 +.

The Xi wall is insulated including corners, studs and top bond beam. The Xi wall is thermally insulated and isolated from the exterior elements. The Xi wall is monolithically poured (poured all at once) with high-strength concrete for solid structural integrity and reinforced with steel rebar and polypropylene fibers.

The Xi wall’s special high strength, low-water concrete mix also requires no additional damp proofing, benefiting from technology developed for the original R-5. The Xi meets or exceeds energy conservation requirements from both the IECC and the IRC (zones 1-5). The Xi has a striking modern look before drywall installation due to the galvanized steel stud facings that have replaced treated wood nailers. The high-tech engineering and numerous advanced features of the Xi make it the foundation of the future and the only choice for selective homeowners.
