Looking for a cost-effective insulation option with reliable thermal performance?
Fiberglass batt insulation is one of the most widely used solutions in both residential and commercial buildings across Iowa.
What It Is
Also known as blanket insulation, fiberglass batt insulation comes in pre-cut flat pieces made of spun glass fibers.
It’s typically installed between studs, rafters, and joists, making it a practical choice for both new builds and retrofits.
This type of insulation remains effective over time because it does not settle—helping to maintain its fiberglass insulation R-value for the long haul.
It’s also one of the most budget-friendly options on the market, available in a wide range of thicknesses and R-values to suit different needs.
Batt Insulation R-Values: R-11 to R-49, depending on thickness installed.
Key Benefits of Fiberglass Batt Insulation:
Common Uses
Fiberglass batt insulation is ideal for insulating attics, ceilings, floors, and walls. It’s especially useful in framing cavities, where its flexibility allows for a snug fit that reduces heat transfer and supports better indoor climate control.
Whether you’re insulating a residential home, post-frame building, or light commercial space, this material offers a dependable way to lower energy costs and improve year-round comfort.
Plus, its fiberglass insulation R-value ratings make it easy to select the right level of thermal protection for your project.

The crew at AFI was outstanding! Work was completed in a professional and timely manner. Highly recommended!
This company is the best. Our home posed many challenges as it is 148 years old with additions of unknown ages. Mike K. and his team faced each challenge with grace and got the job done to perfection. Even with a 70 lb puppy, Milly bringing him toys all day. I highly recommend them!
