GacoOnePass is the first 2 lb. density Closed Cell foam in the industry which can be installed in up to 4” passes which reduces labor costs by 50% or more and offers 20-30% higher yields than standard 2 lb. foams when sprayed in one pass at 3-4” thickness. It is Appendix X approved for use without an additional ignition barrier and meets the requirement for a Class II vapor retarder at just 0.44”.

GacoOnePass is ideal for use in a variety of residential and commercial applications and it can be used in deep fill applications with up to 18” in depth per pass for applications like trench fill, pipe erosion control, container filling, etc.


4” PASSES. Installs quickly; saves time and reduces labor costs.
EXCEPTIONAL SPRAYABILITY. Superior formulation provides consistent, forgiving, user friendly foam with predictable yields and less gun clogging.
LESS VISCOUS. Reduces wear and tear on equipment.
LOWER ODOR. Improves work environment.
ENERGY EFFICIENT. Higher R-values than conventional insulation and a seamless air barrier reduce uncontrolled air leakage, resulting in lower energy costs.
DESIGN FLEXIBILITY. Adheres to the substrate, allowing for easy monolithic installation for greater structural strength and stability, and enhances resistance to water damage; expands to fill even irregularly shaped and hard to reach areas.
SUSTAINABLE AND HEALTHY. Reduces condensation, moisture and mold, provides a sound barrier to help block airborne noise, contains no ozone-depleting chemicals and may contribute up to 20 LEED credits.
LOWER CONSTRUCTION COSTS/VALUE ENGINEERING. Achieve insulation, air barrier, vapor retarder and thermal break all in one for reduced material costs; energy efficiency results in smaller HVAC system requirements.
LONG TERM VALUE. Customers today are concerned about their building’s integrity; spray foam helps a building withstand the tests of the elements and time.
