Crawl space insulation in your home is more important than you may think. 15% or more of a home's total heat loss can be attributed to an improperly insulated or un-insulated crawl space. Reflective Foil Insulation is an excellent product to use for insulating a crawl space. It is strong, light weight and very clean to install, unlike fiberglass insulation. EcoFoil radiant barrier bubble insulation provides a moisture vapor barrier and controls temperature and prevents cool, damp air from invading the floor above. Rolls of reflective foil bubble insulation are made to fit between empty floor joists or stapled right across the bottom for unfinished applications creating an R-value of 10.5.
When installed in a crawl space, or between floor joists, reflective bubble insulation keeps your home's floors warmer in your living area above while regulating temperatures below as well.
