GacoProFill is a two-component open cell polyurethane foam designed specifically for injection into a variety of empty cavities in both residential and commercial applications. It is ideal for use in retrofit projects and also for CMU Block Fill projects.

GacoProFill provides the same benefits as all Gaco spray foam insulation products – high R-value (3.93 per inch) and seamless air barrier help reduce energy costs by up to 40%; it eliminates drafts for increased comfort; and it creates a quieter home by blocking and absorbing airborne noise.

How GacoProFill is different is the key. While other injection foam insulations leave voids and deteriorate if not protected by an air barrier, GacoProFill is both insulation AND air barrier – and because it won’t shrink, settle or sag, it will continue to provide seamless insulation, energy savings and comfort year after year.


EXPANDED SCOPE OF WORK. Differentiate yourself and increase sales by adding retrofit applications to your services.

LESS DOWNTIME. With fewer seasonal restrictions, the re-insulation market offers significant growth potential throughout the year.

NO SPECIAL EQUIPMENT. Install using the same equipment you use for Gaco’s other spray foam insulation products.

EASY TO INSTALL. Ideal for existing homes and buildings with uninsulated wall cavities; install from exterior or interior.

ENERGY EFFICIENT. High R-value and a seamless air barrier reduce air leakage and lower energy costs.

LONG TERM VALUE. Will not shrink, settle or sag; provides a seamless insulation barrier year after year.

HEALTHY. Reduces condensation, moisture and mold, improving occupant comfort, health and safety.

QUIET. Acts as a sound barrier to help block airborne noise and absorb sound.

  • Kevin Frisbie is the Michael Angelo of Insulation! He just made my crawl space look like the Sistine Chapel!! I can’t thank you enough!! For once, I’m looking forward to the winter!!!!!!!!!!!!!

  • Thank you Kevin and team! The basement is drying up and looks great! We’re happily anticipating the difference the foam in the attic will make this summer as well as this coming winter. I can tell a difference in the house already!

  • They just finished up yesterday!! The team was GREAT. I cannot wait to see the money I will be saving. There is no question I will have them come back and insulate my basement (once I put up the 2 x 4 studs in place). I went above my garage space after they finished and the temp. dropped by at least 20 degrees. I give them thumbs up and I am telling everyone how great the Freedom Foam Insulators Team are to work with and how great the product is working at my house.

  • Kevin and his crew did an awesome job on my Morton building.Very professional and left the place cleaner than when they came.He also gave me tips on finishing the building. Thanks.
