Insulation Under Floor System
Insulation under floor refers to insulation that is installed in the crawl spaces under your home to help keep the warm air from escaping during the winter months. Such insulation can be blown-in insulation made of recycled cardboard or other cellulose material; fiberglass, rolled insulation with batting; or reflective sheets that help to keep the warmth inside the house.
According to the US Department of Energy, an uninsulated crawl space costs the average US homeowner $50 extra per year on their utility bills. With the cold New England winters, residents of the northeastern states likely pay even more. The home inspector will check to see that the under-floor insulation is installed correctly and that pipes and ducts are properly wrapped.
