Get answers to common questions about insulation services in Coralville, Iowa.
For our Iowa climate with hot, humid summers and cold winters, blown-in cellulose or fiberglass in attics and walls is highly cost-effective. Spray foam offers superior air sealing and higher R-value per inch, which is crucial for energy efficiency, but has a higher upfront cost. The best choice depends on your home's specific air leakage and your long-term energy savings goals.
Late summer and early fall (August-October) are ideal, as the weather is mild and contractors are less booked than in peak winter. This timing allows you to address any air leaks and upgrade insulation before the harsh Iowa winter hits, ensuring your home is sealed and efficient when you need it most. Avoid the deep winter if possible, as attic work can be complicated by ice and snow.
Yes, MidAmerican Energy offers rebates for Iowa homeowners who add insulation to meet specific recommended R-values, particularly for attics. Additionally, the federal Inflation Reduction Act provides tax credits for qualified energy efficiency improvements. It's crucial to work with a certified contractor who understands the program requirements and can ensure your project qualifies.
Look for licensed, insured contractors with strong local references and specific experience with Iowa's climate challenges. Verify they perform a thorough energy audit or assessment before quoting. Check for membership in local associations like the Iowa City Area Home Builders Association and ensure they are familiar with MidAmerican Energy's rebate program paperwork.
Always prioritize the attic first, as heat rises and it's typically the largest source of heat loss in our climate. Adding attic insulation to the recommended Iowa level of R-49 to R-60 provides the biggest return on investment. After the attic is properly sealed and insulated, then assess wall insulation, which is more invasive and costly but may be necessary in very old homes with little or no existing wall insulation.
