HandiFoam® Low Density Spray Foam is an open cell spray foam designed to fill and insulate, deaden sound and reduce vibrations in larger cavities.  This low density / open cell foam is available in 1350bf and 450bf sized kits to fit your project needs.  It is dispensed using the patented HandiGun™ dispensing unit for accurate and precise applications.

Due to its excellent adhesion properties, HandiFoam® low density spray foam provides an excellent insulation by creating a continuous barrier that completes the building envelope.  This helps improve indoor air quality, lowers heating and cooling costs and reduces energy consumption.  Our easy-to-use spray foam kits assist in attaining ENERGY STAR™ rating and/or LEED credits.

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.
