As building codes continue to become more stringent, and states and localities continue to adopt codes requiring increased energy efficiency and low emissions, Gaco 183M provides a multifunctional solution to the rising cost of building materials required to meet today’s demand for high-performance buildings. Not only does Gaco 183M offer the exceptional all-around performance that spray foam applicators demand, architects and specifiers will appreciate its design flexibility and sustainable contribution to healthy building interiors, along with the energy efficiency and occupant comfort that owners desire.

An air barrier system stops the uncontrolled flow of air into and out of the building envelope, thereby reducing moisture problems, building heating and cooling costs, and greenhouse gas production; it improves indoor air quality, acoustical isolation and the indoor environment; overall, an air barrier system results in sustainable, durable buildings. As an ABAA Evaluated Material as part of an ABAA Evaluated Assembly, Gaco 183M Closed Cell Foam is approved for use in air barrier systems.

Gaco 183M is a Class A (Class 1) fire rated foam and is safe to the environment. It meets the requirements of Appendix X for use in attic and crawl spaces without an additional ignition barrier.


SPRAYABILITY. Superior formulation provides a consistent, user friendly foam with predictable yields.
LOWER VISCOSITY. Reduces wear and tear on equipment with less clogging of guns.
LOWER SPRAY TEMPERATURE. Easier on equipment and more comfortable to apply.
LOWER ODOR. Reduces odor in application, improving work environment.
LOWER COST. No addition ignition barrier needed, saving time and money.
WINTER AND SUMMER FORMULATIONS. Allows you to expand your spray window in colder temperatures.
ENERGY EFFICIENT. Seamless air barrier reduces uncontrolled air leakage, lowering energy costs for building owner and homeowner.
HEALTHY. Reduces condensation, moisture and mold, improving occupant comfort, health and safety.
QUIET. Acts as a sound barrier to help block airborne noises.
RESPONSIBLE. Higher aged R-values than conventional insulation. Reduces energy consumption, and contains no ozone-depleting chemicals. Earn up to 20 LEED credits.
TESTED. ABAA Evaluated and GreenGuard certified.

  • 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.
