Preventing cool or damp air from seeping into the crawl space, Design Specialist J.C.Gibriano proposed the rim joists be sealed and insulated for this customer in Westfield. Additionally, insulation on the walls and floor would help properly encapsulate the area to keep the space isolated from the earth. Foreman Esau Aquino and his crew installed the RimTight Rim Joist spray foam insulation as well as the SilverGlo Insulation Panels on the walls and CleanSpace Crawl Space vapor barrier.
