Spray Foam Insulation Kit Dow Froth Pak 210 Class A Fire Rated

Dow Froth Pak 210 Class A fire rated spray foam insulation kits are complete portable two part polyurethane spray foam systems. FROTH-PAK™ polyurethane foam is a two-component, quick cure, closed cell foam that fills cavities, cracks and expansion joints for insulation and air sealing. Air infiltration accounts for 25%-40% of a home’s energy loss, FROTH-PAK™ stops that energy loss. FROTH-PAK™ Foam Insulation kits can be used to insulate stud wall cavities up to 2" thick, cold floors above unheated areas, crawl spaces, attic walls, and ceilings when covered with a code-approved barrier. The kit can be restarted and reused for up to 30 days after first startup. The Froth Pak 210 kit yields up to 210 board feet of foam.

The Froth Pak 210 kit yields up to 210 board feet of foam (One board foot = 12"x12"x1"), 1.75 foam density.

Froth Pak provides a R-6.6 rating per 1 inch of thickness when sprayed at 2 inches thick.

Kit Includes:

  • Part A Tank - Isocyanate
  • Part B Tank - Polyol
  • INSTA-FLO Dispenser with 9 foot hose
  • Cone Spray Anti-Crossover Nozzles (6 cone nozzles, 4 fan nozzles)
  • 1 Petroleum Jelly Packet (5 g)
  • 1 Operation Instruction Manual

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 200 became the Froth Pak 210. FROTH-PAK™ Class A Insulation now offers increased yield, improved adhesion and resistance to cold during transport and storage.

Chemical curing allows 2 part polyurethane foam to be dispensed, expand, and become tack free in seconds. Foam will skin over in 30 to 40 seconds and be completely cured in under 1 minute.  Dow Froth Pak 210 is great for medium size jobs; yield is 210 board ft.


FROTH-PAK™ Foam Insulation Kits (U.S. only) come with a Class-A fire rating (flame spread index of 25 or less), FROTH-PAK™ Foam Insulation can be used in:

  • Stud wall cavities
  • Rim or band joists
  • Crawl space walls and ceilings
  • Attic ductwork
  • Plumbing wall pipe insulation and support

Please refer to your local building code or local inspector for proper application.
