Heating and cooling account for up to 70% of the energy used in the average Kernersville home. If you want to substantially reduce energy bills, you can employ high-tech and energy efficient insulation to reduce the amount of money you spend on heating and cooling. If you have an older home, you probably know that you need to better insulate your home. Likewise, since most new homes are not built with energy efficiency in mind, even homeowners of newly built homes can benefit from lower energy costs with energy efficient insulation.
