The crawl space of this West Hartland, CT home had poor insulation that was not helping to keep the area warm in the winter and cool in the summer. We installed our TerraBlock Crawl Space Floor Insulation throughout the area. This 3/4" foam insulation is flexible enough to cover the uneven floors of crawl spaces, and it is highly durable and water resistant. It helps keep the area dry as well as providing insulation.
