| Post-and-beam homes with precast concrete foundations  Architect Ken Wertheim places a high priority on enriching mountain settings with his custom home designs. Once completed, his popular timber-framed homes serve as landscape accents to their natural surroundings. "My home designs primarily feature timber frame designs that complement their western North Carolina locations," says Wertheim, AIA and principal of his practice in Asheville, N.C. "I specialize in Timberpeg projects that feature authentic timber framing on both the interior and exterior of the home, using mortise and tenon joinery. Timberpeg packages provide a weather-tight shell, including the timber frame structure, SIPS (structural insulated panel) wall and roof systems, as well as exterior finish materials."Wertheim has married many of his post-and-beam homes with precast concrete foundation systems that also provide weather-tight packages. To achieve optimum energy-efficiency benefits, he starts by specifying Superior Walls XiTM wall panels for his foundations. "The 5,000 psi concrete strength of these wall systems is amazing," says Wertheim. "The walls come pre-insulated, so they provide the homeowners with an energy-efficient basement. And, the builders appreciate using them because they install in less than a day. That means a builder can start the construction process the day after the foundation system is installed." Top-of-the-line Superior Walls Xi wall panels feature steel reinforced concrete and 2-1/2-inches of DOW Styrofoam insulation. The panels are custom designed and constructed in a factory-controlled setting. Unique features of the Xi wall panels include: - 5,000+ PSI concrete - Steel-reinforced top bond beams, concrete studs and footer beams - Horizontal steel rebar inside top and bottom beams - Vertical steel rebar inside each stud - Access holes for ease in wiring and plumbing - Galvanized steel stud facing ready for drywall finishing - Insulated corners, studs and bond beams "Superior Walls products are resource efficient, using up to 70 percent less concrete in a new home than conventional foundations," says Dave Varner, president of Superior Walls of North Carolina. "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." Wertheim has specified Superior Walls systems for several dozen of his home projects over the past 12 years. One of his most recent home designs, in Black Mountain, N. C., used the Xi system as the foundation for the 2,800-square foot timberframe home. "The family in this home enjoys the sense of 'connection' with the mountain setting," says Wertheim. "Part of that connection is a sense of stability and security that comes from having a precast concrete foundation. The systems available from Superior Walls of North Carolina complement my overall home designs and bring long-lasting energy-efficiency benefits to the homeowners." The Superior Walls insulated precast concrete wall systems specified by Wertheim in his projects have earned the Green Approved Product designation by the NAHB Research Center. Builders choosing to use Xi and R-5 foundations can earn up to 13 points on a project toward a National Green Building Certification. write your comments about the article :: © 2011 Construction News :: home page |
