Product Description


FROTH-PAK™ 620 is now FROTH-PAK™ 650


Dow Chemical has made enhancements to their industry leading formulation of FROTH-PAK™ Class A Insulation. As a direct result of these formulation enhancements, FROTH-PAK™ Class A Insulation now offers increased yield, improved adhesion and resistance to cold during transport and storage. With a yield improvement of 5% over the incumbent formulation, FROTH-PAK™620 will now be known as FROTHPAK ™650. 


Dow Froth Pak 650 Class A fire rated spray foam insulation kits are portable two part polyurethane foam kits. FROTH-PAK™ spray polyurethane foam is a two-component, quick cure foam that fills cavities, cracks and expansion joints for insulation and air sealing. It is available in disposable kits for smaller jobs and refillable cylinders for applications that require a greater amount. FROTH-PAK™ Foam Insulation kits are well-known for insulating stud wall cavities up to 2" thick, cold floors above unheated areas, crawl space and attic walls, and ceilings when covered with a code-approved barrier. The kit can be restarted and reused for up to 30 days after initial startup. The kit yields up to 650 board feet of foam.  One board foot is shown here:

  1. Foam-Pak 620

    Posted by Ged on 11th Oct 2013

    Product was delivered 2 days after order was placed,exceptional. I used this to insulate a sub floor resting on a concrete base and theFoam-Pak 620 fullfilled this need. It was easy to use carfully following the instructions. I used up the entire contents in one go so cannot comment on storage and re-use. One down side is that it did no go as far as I expected. The 620 board feet (1.4 cu m)listed is theoretical in ideal lab conditions. I would like to know what the practical volume usage is.

  2. good product.

    had a small problem with the left hose at the sprayer that seeped some material out. wasn't a big deal though. product sprays and covers well. make sure they are warm like the instructions explain or inconsistent coverage. warmed mine up and worked great. once applied, this product is amazing, like most any spray foam.

  3. sprays beautifully

    and besides that it is easy to use--you really have to plan what your doing so you don't have to change nozzles all the time

    I was satisfied with how the Froth-Pak went on. I initially heated the tanks up to 80 degrees and kept them around 75. I was able to do just under 500 square feet. Most spots at an inch thick while other places thicker. I applied it in on my basement walls behind a studded wall. One thing I will do differntly next time is use the "spot" tip to apply the foam behind the studs (~3/4" space) first and then go back through and use the fan tip to fill the spaces between each stud.
