Crawl space insulation has only been required in newly constructed homes since 1992. Up to 25% of the heat in your home could be lost through an un-insulated crawlspace. Think about all of the cold space under your home that is drawing away the energy that you’ve paid for! The US Department of Energy recommends a minimum of an r-25 insulation installed in all homes.
