Window and door frames shape far more than sight lines and operation. Frame material choices influence structural performance, thermal behavior, condensation risk, durability, maintenance cycles, resilience, safety, and long-term homeowner satisfaction. Often fenestration options are evaluated simply on base price and warrantee, however by considering the whole cost, from installation through a long-life of service, occupants can benefit from a more thoughtful specification process.
This presentation compares common residential frame materials, including vinyl, fiberglass, aluminum, steel, wood, and wood-clad systems, and connects material properties to design goals and real-world performance. Participants will learn how to evaluate tradeoffs, coordinate details with the building enclosure, and write clear specifications that support energy efficiency, durability, security, and occupant comfort in custom single-family homes.
