Whether you’re a homeowner or builder, when it comes time to deciding on a Superior Walls foundation for a home, you have some decisions to make.

Both the Xi and Xi Plus precast wall panels are energy efficient. They both are custom constructed to meet your exact needs. And, they both install on the job site in just a day (or less!) by a certified crew.

So, how do you decide which wall system to use? Here’s the breakdown that will help you make your decision.

  • Steel-reinforced top bond beams, concrete studs and footer beams
  • Horizontal steel rebar inside top and bottom beams
  • Vertical steel rebar inside each stud
  • Insulated access holes for ease in wiring and plumbing
  • Galvanized steel stud facing ready for drywall finishing
  • Insulated corners, studs and bond beamsSuperior Walls Xi Plus wall panels have many of the same features of the Xi walls, plus:
  •  Dow® THERMAX polyisocyanurate insulation covering rigid foam insulation
  • 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.

Xi Plus panels are available with a built-in insulation value of R-21.3 in U.S. markets and can be insulated up to R-42+.
