Best Practices Case Study: David Weekley Homes - Eagle Springs and Waterhaven, Houston, TX

Case study describing David Weekley Homes, Houston Division, has qualified more than 1,240 homes for the DOE Builders Challenge. Advanced framed 2x6 walls with open headers and two-stud corners allow more room for R-20 damp sprayed cellulose wall cavity insulation that is covered with R-5 rigid XPS foam. A radiant barrier cuts heat gain in the R-38 insulated vented attics. Draft stopping at fireplace and duct chases and behind tubs, gluing sheetrock to framing, and extensive caulking make for air-tight homes at 3.0 ACH50.
