Product Overview

GREAT STUFF Fireblock Insulating Foam Sealant with Quick Stop Straw Technology can save much more than energy costs. By sealing the pipe, cable and duct penetrations, you minimize airflow. During a fire, that means flames, harmful gasses and toxic smoke cannot spread as quickly. And in an emergency, that could make all the difference. The fact that it helps you conserve energy, reduce drafts and save on heating and cooling costs is great too.
  • New quick stop straw technology - helps stop messy foam drips
  • Impedes spread of fire and smoke through service penetrations
  • Recognized as an alternate fire blocking material for residential construction; tested according to ASTM E84, ASTM E814 (modified), UL 1715
  • Seals service penetrations between floors and electrical runs through wall studs
  • Airtight, water-resistant and has exceptional adhesion to building materials
  • Tack free in 6 minutes; trims in 30 minutes; cures rigid in 8 hours
  • Bright orange colored foam for easy code identification

Rick, It is not clear, even after review of the SDS (link below) on the Home Depot Website whether Dow recommends that this product be used for this purpose. There is contact information on the SDS to ask the question directly from the manufacturer. https://images.homedepot-static.com/catalog/pdfImages/ae/ae04d0fa-fb09-4fec-a1af-8bf6fae37217.pdf

How many hours rate ?

Asked by Eduvida60 October 5, 2020

Answer

Dear Eduvia: Zero. In fact, despite "Fireblock" on the label, this and all versions of Great Stuff spray foam are VERY flammable. The cured foam will ignite at just 240 degrees F, which is significantly lower than the ignition temp for wood. So Great Stuff will burn first. Never install this or any type of Great Stuff or similar canned spray foam (e.g. 3M) near any source of heat, e.g. recessed lights, furnace ducts, fireplaces, ovens, etc. This type of spray foam is also banned for "fire stopping" in commercial buildings -- to seal gaps and holes around electric cables and pipes, etc., and we never use it in residential construction because smart building inspectors can fail an inspection if this type of product is used. We always use true fire resistant sealant, e.g. 3M Fire-Barrier caulk, 3M Model # CP25WB+10, Home Depot Internet #100166701, UPC Code # 051115116384 Store SKU #163096 If you need to fill a larger gap or hole, first pack it with rock wool then cover the surface with this 3M caulk. I hope this is helpful, Mark

What is the temperature rating

Dear Tom: Even though this version of Great Stuff foam has "Fireblock" on the label, it is just a flammable as sll of the other versions of Great Stuff. The cured foam will ignite at just 240 degrees F -- which is much lower than the ignition temp for wood. In short, Great Stuff Fireblock is VERY flammable. If you need to seal an area near a source of heat, use real fire resistant sealant, e.g. 3M Model # FB 136 , Home Depot Internet #100390499, UPC Code # 051115165917 Store SKU #191728 If the gap your need to seal is larger than ~1/8", pack it with rock wool or fiberglass insulation, then cover the surface with 3M FB sealant. I hope this is helpful, Mark

Physically, you should be able to cut it or chisel it out. Use an xacto knife or chisel to remove the material. I don't see any special precautions to discard excess material. I know that sunlight will dissolve/degrade the foam.

Only a medical professional can answer your question definitively. The following is from the Dow Chemical web site "Find additional information and the Product Safety Assessment for one-component Polyurethane Foam Sealants and Adhesives at www.dowgreatstuff.com. You may also contact The Dow Chemical Company at 866-583-2583 (BLUE). General information regarding the safe use of polyurethane foams can also be found at www.spraypolyurethane.org."

DOW “consumer safety” document, so I contacted DOW for clarification. Here is their reply: “The max-use temperature of the product is 240 degrees F as you stated.” Copies of DOW’s latest MSDS and ‘consumer safety’ documents are attached. Note: the same concerns apply to foam ‘fireblock’ products from other manufacturers, e.g. DAP® Fireblock Foam Polyurethane Foam Sealant.

Dear Rick: NO! Even though this version has "Fireblock" on the label, every version of Great Stuff (and similar canned spray foam from 3M etc.) is very flammable and will ignite at just 240 degrees F, which is significantly lower than the ignition temp for wood. So Great Stuff will ignite first! In short, never install Great Stuff near any source of heat, e.g. recessed ceiling lights, heating ducts, fireplaces, etc. And never use Great Stuff to create a true "fire block" seal. We always use true "fire block" sealant, e.g. 3M Model # CP25WB+10, Home Depot Internet #100166701, UPC Code # 051115116384. If the gap is more than ~1/4", pack it with rock wool (which is non-flammable) then cover the rock wool with 3M sealant. I hope this is helpful. Mark

The cured foam will ignite at just 240 degrees F, which is significantly lower than the ignition temp for wood. So never install Great Stuff or similar canned spary foam near any source of heat, e.g. a dryer vent. The best solution is non-flammable fire barrier caulk, e.g. 3M Model # CP25WB+10, Home Depot UPC Code # 051115116384 Store SKU #163096 If the gap is larger than ~1/4", pack it with rock wool then cover the rock wool with 3M caulk.

Dear Tina: The team at Fine Homebuilding ran a series of tests on Great Stuff foam. Here is what they found, plus some tips for installation: (1) Standard cans with the straw applicator produce 36 cubic inches per ounce. With a 16 ounce can this equals 576 cubic inches or 1/3 cubic feet. (2) The larger 'pro' cans that are used with a gun instead of a straw increase the yield by 33%. A gun also makes application easier compared to the small straw on the consumer cans. Surprisingly, however, the standard consumer "Gaps and Cracks" version is the cheapest per ounce. Even though the 'Pro' cans deliver more cured foam per ounce, they are a bit more expensive. (Pro cans and guns are available at Home Depot, in addition to consumer cans with the straw.) (3) Great Stuff is a one-component foam that uses moisture in the air to cure. If you spritz the foam with a little water after you apply it, you can boost the volume by 73% (gun) to 92% (straw). This also improves the density of the cured foam and accelerates the curing process. (4) Results with a spritz of water, 'Pro' cans with the gun will yield 83 cubic inches per ounce, and the straw cans yield 69 cubic inches per ounce. With a 24 ounce can and a gun, this equals 1,992 cubic inches or 1.15 cubic feet. With a 16 ounce can and a straw, this equals 1,104 cubic inches or .64 cubic feet (5) To fill a larger hole, apply one layer of foam, spritz it with water and let it cure. Then repeat the process. Do not try to fill a large hole or gap in one go; the foam will not cure properly. (6) Cured Great Stuff foam is very flammable (including the 'Fireblock' version) and will ignite at just 240 degrees F. This is significantly lower than the ignition temp for wood. Do not install it near anything that might get hot. Large areas in a home, garage, basement or storage area must be covered by an approved thermal barrier, e.g. 1/2" drywall. (7) Great Stuff sticks tenaciously to everything, including painted surfaces, carpet, your hair and hands, etc. No standard solvent will dissolve it; you have to let it cure, then scrap, sand or scrub it off. So wear gloves and eye protection, and tarp off anything nearby when you spray it. (8) The 'Window and Door' version remains flexible after it cures, to prevent cracks. This is ideal to seal air leaks around doors and windows, foam board joints and edges, framing etc. I hope this is helpful. Mark

How do you get rid of Tom Cat glue on A dog? I know that this is kinda sticky sticky mess any ideas? It's kind of funny

Asked by Leslie June 26, 2020

Answers

I’m not sure what Tom cat glue is but if your dog got expanding foam on him or herself then acetone will dissolve it. Just be very careful not to leave any on the dog or let them lick it or get it in their eyes ears or nose. It can be irritating to the skin and is poisonous if ingested. It will strip away all the oils from skin and hair so definitely wash it off completely.

Listen to control the flow; 1 oz./linear foot
I bought this a while ago, and finally found/made the time to use it. 1) mist all of your potential work areas first with water; although it is possible to reuse the same disposable spray straw with 2 cans, you need to empty the can once you start spraying, else the straw dries out; 2) plan on 1 oz./linear foot; I sprayed four 16 oz. cans on the 1st floor joists above our unfinished basement, and it covered about 58 linear feet (although I sprayed it on a bit thicker than planned/anticipated until I figured it out); 3) I found that the best way to regulate the flow was to listen for the sound of the propellant gas escaping—the slower it escaped (up to a 5-10 second delay before the foam started flowing), the better I was able to control it, especially when the pressure was high with a new can; 4) wear gloves and eye protection, and let it dry before you try to clean up (then spills just popped off the concrete floor); 5) fill in large gaps with wood scraps before spraying, and it may take a few sprays (allowing drying time in between) to fill in large gaps (e.g. between joists a couple of inches apart). I am very proud of the attached photo as “my best endeavor,” as most of the rest of the floor joists showed quite a bit of extra foam...

Response from GREAT STUFF & DuPontNovember 13, 2020
Hello, Ben - Thanks for sharing your comments about Great Stuff™ Fireblock. We apologize for an inconvenience you've had. The Quick Stop Straw is designed to close when you tap the end of nozzle to allow you to move from one place to another and to prevent foam from dispensing. However, the foam will cure in the can within two hours of initial use due to air and moisture inevitably getting into the can. We have developed a new dispenser called the Great Stuff™ Smart Dispenser™ that allows for greater control and makes the can restartable for up to 30 days after initial use.
