Seal air leaks & add insulation for an energy upgrade that pays for itself

Don't forget to seal leaks!

Sealing air leaks and adding insulation can help:

  • Increase overall comfort
  • Reduce outside noise
  • Improve humidity control
  • Lessen the demand on your HVAC system
  • Improve indoor air quality

The attic is typically the biggest source of energy loss in a home. Installing the right amount of insulation and sealing air leaks can make a big difference in your energy bills and comfort.

Insulation levels and thermal performance are measured by R-Value. The higher the R-value, the better the insulation's ability to resist heat flow.

Many homes have as little as 9 in. of attic insulation in regions where the U.S. Department of Energy recommends 16 in. It is recommended that most homes in Illinois have between R-49 and R-60 of attic insulation, depending on the insulation material.

Air sealing is a critical step when insulating an attic because sealing air leaks stops conditioned interior air from leaking into the attic. Air sealing can prevent attic mold and significantly reduce heating and cooling bills. Dr. Energy Saver N.E. Illinois uses a variety of materials and techniques to stop this energy-wasting air leakage. Be sure to check out our specialized SuperAttic™ System for continuous & airtight coverage.
