Wall Insulation 
 
 
For Electric & Natural Gas Customers

Whether you are updating your current home or building a new one, properly insulated exterior walls will not only increase comfort but also help you save on heating and cooling costs. Before insulating your walls, you should ensure that they're properly air sealed. Air leakage, or infiltration, occurs when outside air enters a house uncontrollably through cracks and openings. Properly air sealing, such cracks and openings in your home, can lead to natural gas and electric savings and a healthier indoor environment.
