Xi and R-5 insulated precast concrete wall systems

The industry’s first NAHB Green Approved foundation systems, Superior Walls’ Xi and R-5 insulated precast concrete wall systems use up to 70 percent less concrete in a new home than conventional foundations. The custom wall assemblies contribute to the overall home insulation value and help reduce air infiltration into the home, potentially lowering energy costs. The foundation systems come complete with built-in accesses for wiring and plumbing, stud facing for easy drywall installation, and custom openings for windows and doors.

Editors’ Comments: Higher R-value, reduced air infiltration, less concrete. What’s not to love.
