This is a Poured Concrete Crawl Space Walls with Vents. Triple H went into this home and started insulating this crawl space by installing our insulated vent covers outside. Then the crew added SilverGlo foam insulation to all the walls inside the crawl space. the results of adding this insulation to the crawl space is much warmer crawl space and floors upstairs, ducts are in a warmer environment, and less drafts.
