Air Sealing and Attic Insulation
Adding insulation to your attic is often one of most cost-effective upgrades you can make to save money on your utility bills and create a more comfortable home for you and your family.
ENERGY STAR recommends homeowners in northern Illinois insulate their attics to a minimum R-value of R49, The Energy Code for the State of Illinois requires all new homes to have R-49 attic insulation.
When you add insulation to your home, it’s a good idea to air seal at the same time. Air sealing consists of closing up all of the places in your house where hot air leaks out in the winter and in during the summer months, forcing your HVAC equipment to work harder. By sealing up all those leaky spots, your insulation will be much more effective.
