Spray Foam Insulation Kit FROTH-PAK™ 210 Class A Fire Rated

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

DuPont 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.  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

Safety & Use

Important Safety & Use Information

FROTH-PAK™ spray foam kits are intended for professional use - Please follow all instructions and guidelines for use and application.

Personal Protection Equipment should be used when applying FROTH-PAK™ foam kits.

Personal Protection Equipment Recommendations

Froth Pak Safe Handling Instructions

FROTH-PAK™ Usage Recommendations

As with all chemical products proper preparation of the work area and application procedures should be followed to insure a safe and satisfactory job.

When spraying FROTH-PAK™, the initial reaction of the 2 chemicals will generate heat. We recommend building up thickness in a series of layers to avoid excessive heat buildup. 

Proper ventilation of the work area should be followed. Please see Froth Pak Ventilation Guidelines.

Please make sure that both tanks are opened fully and that there are no restrictions in the feed lines. An improper mixture will cause "off ratio" foam. To see what this looks like check out our video "How to tell Good from Bad"

    This is great stuff

    Posted by Dan in PA. on Aug 9th 2016

    I've bought several of these kits, and the larger tanks too, the 600 series. The stuff is pricey, but it's worth it. Warehouse full is the best price on ebay, and on the rest of the internet. Dress up, wear a respirator. There's so many applications for this stuff, and Warehouse full is a great vendor. Call them, they can take orders over the phone, pay extra for a 30' hose kit, etc. I'll be ordering more from them, and I just recommended them to a friend yesterday. You hold a lighter to this stuff and it doesn't burn, and it's over R5 per inch. You'll be happy with this product.
