Crawl space insulation is a key factor in maintaining energy efficiency and comfort in your home. Unfortunately, many crawl spaces are poorly insulated – or not insulated at all!
The experts Green Building Advisor are straight forward: “Crawl space walls should be insulated with rigid foam or closed-cell spray polyurethane foam.”
