Homebuilders Push for Documented Thermal Performance Standards
Homebuilders replacing standard vinyl window units under mounting energy-code pressure are increasingly specifying manufacturers with documented thermal-performance certification over standard equivalents in vendor selection decisions across most major residential-construction programs. Andersen Corporation and Pella Corporation have both expanded certified thermal-performance capacity over the past two years to serve this growing homebuilder demand. At least a dozen major regional homebuilders have qualified new certified thermal-performance partnerships since 2023, and manufacturers report this shift is meaningfully expanding addressable contract demand across multiple residential-construction programs, with several additional homebuilders evaluating comparable programs soon worldwide.
