Superior Walls of America

The Xi Plus product line of insulated precast concrete wall systems are custom-made for the exact needs of each project. The enhanced Xi Plus walls feature the additions of Dow THERMAX reinforced polyisocyanurate insulation covering rigid foam insulation and a 4-inch insulated footer beam. A 4-inch standard floor slab may be poured equal to the height of the footer beam eliminating the need for an additional screed board. The panels are now available with a built-in insulation value of R-21.3 and can be insulated up to R-42+. The energy-efficient walls help lower energy costs and reduce energy leakage while providing increased living space in a comfortable setting. Builders also benefit from saved job site time and labor when certified 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 IECC and the 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.
