They provide low cost, high impact home upgrades engineered to save homeowners more in heating and cooling expense than the upgrades cost. Types of installation include brown cellulose, spray foam, air sealing, dense packing, and radiant barriers. Sustainergy uses as environmentally-friendly insulation as much as they can.
