A well-insulated attic reduces home maintenance costs and improves whole-house efficiency. In addition to proper ventilation, and window and door seals, insulation is the best way to ensure your home stays warm in winter and cool in summer.
Air leaks between the living space and attic let warm, humid air enter your house in the summer and let expensive heated air escape in the winter. Seal spaces behind walls that were left open to the attic; holes where wiring, plumbing or ductwork penetrate the ceiling; and cracks between sheetrock and chimney flashing.
To be sure you’ve discovered and closed all air leaks, have your HVAC contractor inspect the attic and seal any leaks that you can’t take care of yourself. Look for other air leaks around your house to seal for improved whole-house efficiency.
Check the Insulation
Be sure your home’s attic insulation is adequate for the Chicago climate. If the insulation present is too thin or has been damaged by rodents or moisture, you’ll get a good return on your investment by upgrading it. Adding fiberglass batts or blowing in loose-fill insulation is a job you might do yourself, but hiring an experienced contractor will ensure all of the details are taken care of correctly.
Provide Adequate Ventilation
Adequate attic ventilation reduces summer cooling costs by preventing excessive heat buildup in the attic. It also reduces home maintenance costs by controlling humidity and preventing ice dams in the winter. Your HVAC contractor can add soffit and ridge vents as part of an overall project to seal attic air leaks, upgrade attic insulation and improve attic ventilation.
