Get answers to common questions about insulation services in Thompson, Iowa.
For Thompson and most of Iowa's climate zone (Zone 5), the U.S. Department of Energy recommends an attic insulation R-value of R-49 to R-60. This high level is specifically required to effectively combat our region's extreme temperature swings—bitterly cold winters with strong winds and hot, humid summers. Properly meeting this target is crucial for energy efficiency, comfort, and preventing ice dams on roofs during winter thaws.
The ideal times are late spring (May-June) and early fall (September-October). These periods typically offer mild, dry weather, which is important for projects like attic work or exterior foam board installation. Scheduling during these shoulder seasons also ensures the work is completed before the peak heating season begins, allowing you to maximize energy savings during our harsh Iowa winter.
Yes, homeowners should first check with Allamakee-Clayton Electric Cooperative, the local utility provider, for any current energy efficiency rebates. Additionally, Iowa has a statewide sales tax exemption for certain energy-saving home improvements, including qualifying insulation materials and labor. A reputable local installer will be knowledgeable about these programs and can help you navigate the application process.
Prioritize contractors who are licensed, insured, and have verifiable local experience. Ask for references from homes in Thompson or nearby towns like Buffalo Center or Lake Mills, as they understand our specific building styles and weather challenges. Ensure they provide a detailed, written estimate that includes the type of material, R-value to be achieved, and a clear scope of work.
For existing walls in Thompson's historic homes, dense-pack cellulose or blown-in fiberglass are the most common and effective solutions. These materials are installed through small exterior or interior holes, filling wall cavities completely to reduce drafts and improve thermal performance. It's a less invasive method than removing siding or drywall and is highly effective against our windy prairie climate.
