Summer is right around the corner! Do you have the correct amount of insulation in your home? HOC offers conditioned attics that block summer heat from entering the home.
Maybe you are looking to cut energy cost? Full envelope sprays are estimated to decrease your energy bill by 2/3. HOC spray foam insulation uses only closed cell products, which give you more rigidity and R value per inch. Skip the cost and process of v***r barrier, spray foam is 100% v***r barrier at 2” or greater.
