Put a blanket over your home for the Winter AND the Summer. Most homeowners do not realize that the benefits of sufficient attic insulation extend to both Winter and Summer conditions.During the Winter months, blown-in insulation prevents heat loss through the attic space, the source of 40% of heat loss in most homes. During the Summer months, the same insulation works in reverse: retaining cool air that is lost through heat expansion through the attics.Together, the effects of blown-in insulation are increased energy efficiency throughout your home and reduced energy costs throughout the year.See our crew in action today installing Owens Corning ProCat Insulation in an attic in Littleton, CO.
