Triple H went into this home in Brentwood, NY to better insulate the crawl space. The home was uncomfortable and the floors above the crawl space were always cold. Triple H insulated the crawl space walls with spray foam insulation. The closed cell spray foam is installed from the bottom of the walls, over the sill plate, and to the top of the rim joists. With this added insulation there should be less humidity, less drafts, much warmer floors, and a more comfortable house.
