Get answers to common questions about insulation services in Fox Valley, Illinois.
For our cold winters and humid summers, blown-in cellulose or fiberglass insulation is highly recommended for attics to achieve a high R-value (aim for R-49 to R-60) and create an effective thermal barrier. These materials fill gaps well, reducing air leaks that drive up heating costs. Spray foam is also excellent for air sealing but is typically more expensive and best for specific applications like cathedral ceilings or rim joists.
While insulation can be installed year-round, the ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for certain installations like spray foam. Scheduling during these shoulder seasons also ensures your home is prepared before the extreme temperatures of our Illinois winter or summer peak, and you'll find greater contractor availability.
Look for licensed, insured contractors with strong local references and proven experience with Fox Valley homes. Verify they perform a thorough energy audit or assessment before quoting. It's also wise to choose a company knowledgeable about local building codes, like the 2018 IECC amendments adopted by many Illinois municipalities, and one that offers a detailed, written warranty on both materials and workmanship.
Absolutely. In our climate, outdated or settled insulation is a major cause of drafts and high energy bills. The top priorities for Fox Valley homes are the **attic** (the primary source of heat loss) and the **basement rim joists** (where the foundation meets the wood frame, a major source of cold air infiltration). Sealing air leaks around windows, doors, and penetrations before adding insulation is a critical step for maximum effectiveness.
