Heating and cooling make up between 40 and 70% of a home’s annual energy bills. Stopping air movement is the first step you need to take to create a more even tempeture in your home. Once you’ve sealed up the holes in the outside of your home, adding insulation will greatly increase the comfort and savings on your heating & cooling bills. Insulation does slow/stop airflow through the material which is itself a great insulator, but it does not stop air flow at the edges. So again, let me stress that you should seal the cracks and holes first BEFORE adding insulation.
