This Old House (1979)

Episode Overview

Tom Silva showcases the vintage v-shaped gutter he crafted for the front porch before guiding us through the house to discuss his plans for spray-in insulation. He shares that many of the steps are standard for insulation projects, such as using vent chutes to maintain a cool roof. He also had to cover the windows to shield them from overspray and construct one side of the interior walls in the rooms where he aims to improve sound insulation. Paul Kennedy highlights the difficulties he encountered while working with the home's steel studs. Following the spray-in urethane insulation procedure, Tom details the process—from mixing the two-part solution on a truck to spraying it into the stud bays, where it expands dramatically. Afterward, he trims the excess to prepare for drywall installation. This system not only provides insulation but also serves as a vapor barrier and air sealant. Meanwhile, painter George Hourihan shares some valuable industry tips outside.
