In 2012 Superior Walls stepped up its game by introducing the  Xi Plus line of precast foundation walls. Custom-made for the exact needs of each project, Xi Plus panels feature superior strength and insulation for the creation of dry, warm and energy-efficient foundations.

Building on the success of our popular Xi walls, the enhanced Xi Plus walls feature the additions of Dow THERMAX reinforced polyisocyanurate insulation covering rigid foam insulation and a four-inch insulated footer beam.

A four-inch standard floor slab may be poured equal to the height of the footer beam eliminating the need for an additional screed board, which saves time and money in the construction process. Xi Plus panels come with a built-in insulation value of R-21.3 and can be insulated up to R-42+.

Top-of-the-line Xi Plus wall panels are based on the proven design of the Xi wall system and provide builders and homeowners with additional superior benefits. Each custom-made panel is manufactured to the specific needs of a project. Features include:

• 5,000+ PSI concrete reinforced with rebar and polypropylene fibers
• Four precast and insulated access holes in each standard stud to provide greater ease in wiring and plumbing
• Horizontal steel rebar inside top and bottom beams
• Vertical steel rebar inside each stud
• Insulated corners, studs and bond beam
• Galvanized steel stud facing
• Thermally isolated/insulated from exterior

“All Superior Walls products are resource efficient, using up to 70 percent less concrete in a new home than conventional foundations,” says Jim Costello, president of Superior Walls. “The custom-made walls include precast openings for windows and doors while stud facings eliminate the need for additional wood framing prior to interior finishing. Using fewer materials helps reduce the carbon footprint of the new home’s construction process.”

If you’re a homeowner, the benefits of Superior Walls precast concrete wall systems are substantial. The energy-efficient walls help lower energy costs and reduce energy leakage while providing increased living space in a comfortable setting. And, your builder benefits from saved job site time and labor when certified Superior Walls installation crews set the walls in place in less than one day, so that home construction can immediately begin the following day.

Xi Plus wall panels provide R-values that meet or exceed energy conservation values from both the International Energy Conservation Code (IECC) and the International Residential Code (IRC). The foundation walls can help in the construction of an ENERGY STAR qualified home. As a custom wall assembly, Superior Walls products contribute to the overall home insulation value and reduce air infiltration into the home, thereby making a huge impact on the overall energy efficiency rating of the home.
