The Department of Energy states that adequate insulation in exterior walls, attic, ceilings, basement walls, floors and crawl spaces can save you up to 30% on home energy bills. If your home’s insulation level is inadequate it is like wearing a t-shirt outside in a snowstorm. I am sure you would not do that! So why is your home insulated poorly? Builders would rather put the money in things you can see like crown molding or granite counter tops. With rising cost of energy this is a great place to conserve by upgrading your insulation in your attic, walls etc.
