  • When provided with 1/2″ of Dow® THERMAX™ insulation and 4-1/2″ of rigid foam insulation, Xi Plus wall systems manufactured in the U.S. have an insulation value of R-21.3. In Canada, the Xi Plus wall system is provided with 5” of Neopor rigid thermal insulation with an insulation value of R-23.
  • Four insulated access holes are included in each standard stud to provide greater ease in wiring and plumbing.
  • The Xi Plus also comes with a four inch insulated bottom footer beam. The standard 4″ thick floor slab may be poured equal to the height of the footer beam, eliminating the need for an additional screed board, saving time and money in the construction process.
