This FAA Report to Congress examines the aging of federally funded sound insulation installed in homes near airports to reduce aircraft noise, focusing on treatments installed before 2007 such as window and door replacements, weatherstripping, and other upgrades. The report identifies key factors affecting long-term effectiveness, including product quality, installer workmanship, deterioration over time, and lack of homeowner maintenance. It draws on research covering over 143,000 residences treated since the early 1980s and offers recommendations for repairing or replacing insulation that has exceeded its effective lifespan.Open full document
