HandiFoam® Slow Rise HFO Spray Foam Insulation is a slower curing closed cell polyurethane foam designed to fill and insulate larger cavities.  Our easy-to-use foam kits come in 41ft³ and 12ft³ sizes to fit your project.  It is dispensed using the patented Handi-Gun™ dispensing unit for accurate and precise applications.

Due to its excellent adhesion properties, cavity fill / pour-in-place spray foam provides an excellent insulation by creating a continuous air barrier that completes the building envelope.  Our wall cavity foam insulation kits help improve indoor air quality, lower heating and cooling costs, and drastically reduce energy consumption.  Our easy-to-use foam kits assist in attaining ENERGY STAR™ rating and/or LEED credits.

**This kit is manufactured with an environmentally friendly Low GWP (HFO) blowing agent and is AVAILABLE TO SHIP TO ALL STATES.

Installation Tips:

  • Temperature: Spray foam products are temperature sensitive.  You can spray this kit in colder outdoor temperatures, the key is to keep the core temperature of the tanks within the proper range of 75-85°F.

  • Change Nozzles: It is important to change the nozzle after you stop spraying for more then 30 seconds.  Failure to change nozzles may result in damage to the spray gun.

  • Reuse Nozzles: It is possible to clean and reuse a nozzle 2-3 times.  As soon as you are done spraying, remove the nozzle and drop it in a can of acetone.  You can also use our Handi-Cleaner to clean out uncured foam.

  • Safety Considerations: Our Safety Kit includes a tyvek suit with hood, respirator, goggles, and 2 pairs of nitrile gloves.

  • Application: Use a slow, steady, and smooth motion to spray a continuous layer when applying the foam.  Spray what appears to be just under a 1/4" thickness and it will expand and cure to roughly 1 inch.  Apply additional layers until desired thickness is achieved, allowing at least 10 minutes between layers.

  • Clean Up: You can clean up uncured foam with Handi-Cleaner.  Once foam is fully cured, you will have to remove it by mechanical means.
