Looking for insulation that delivers strong thermal performance, soundproofing, and long-term energy savings?

Our blown in blanket insulation system is one of Iowa’s top choices for upgrading comfort and efficiency—especially in attics, walls, ceilings, and hard-to-reach spaces in both homes and commercial buildings.

What It Is

The Blown-In-Blanket Insulation System (BIBS®) is a patented process that uses specially manufactured fiberglass blowing wool—making it a proven, state-of-the-art solution for both residential and commercial applications.

Compared to traditional batt insulation, the blown in blanket insulation used in BIBS® is more efficient, delivers excellent sound control, and achieves some of the highest R-values on the market.

This allows it to quickly pay for itself by significantly lowering energy bills. Here’s why more Iowa homeowners and builders choose BIBS®:

  • High-performance energy savings – R-values from R-15 to R-56 help reduce heating and cooling costs

  • Exceptional soundproofing – A tighter fit means less noise from outdoors or between rooms

  • Eco-friendly – Contains a minimum of 25% recycled content

  • Safe for homes – Non-flammable and formaldehyde-free

  • Fills every gap – No cold spots, drafts, or settling over time

  • Trusted system – Installed by certified professionals using proprietary methods

This BIBS insulation system is also mold-resistant and designed to perform in Iowa’s ever-changing weather conditions—giving you peace of mind year-round.

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!
