The DOE recommends R-38 to R-60 for attics in most of Iowa. West Des Moines falls in climate zone Midwest — hotter climates need less, colder climates need more. If you currently have R-11 or less, upgrading to R-49 typically cuts heating/cooling costs by 15–20%.

Should I remove old insulation before adding new in West Des Moines?
If old insulation is damaged, contaminated (pest droppings, mold, vermiculite asbestos), or wet, remove it before adding new. For old fiberglass batts in good condition, blown-in insulation can usually be added on top. Removal adds $1.50–$2.50/sqft to the project cost in West Des Moines.
