Customer Questions & Answers

Can this be used to insulate a tub?

Can this be used to insulate a tub?
Asked by: CofLafayette
Yes, with some important caveats. First, all versions of Great Stuff foam are very flammable and will ignite at just 240 degrees F, so do not apply it next to a heating unit or pump if your tub has a built-in 'whirlpool / jet' system. Second, you will need to apply the foam in stages to allow it to cure properly. Spray one layer, then let it expand and cure completely over a couple of hours. Then apply another layer. If you fill a larger space in one shot, the foam will not cure properly. Third, spritz the foam with a light mist of water from a spray bottle, immediately after you apply it. Great Stuff cures by pulling moisture out of the air. A light spritz of water will double the output per can and improve the quality of the cured foam. Another option that will be easier if your tub has not been installed yet: simply pack the gaps with Roxul rock wool. Roxul provides R-4 insulation per inch of thickness. It is much denser than fiberglass, molds kind of like clay and stays where you put it. See: Roxul Model # RXCB351525, Home Depot Internet #202090820 Store SKU #974419. Simply tear chunks off the batts and stuff it into the gaps around your tub. Roxul is made from rock fiber, and like fiberglass insulation these fibers are itchy. So wear gloves and a dust mask when you install it. I hope this is helpful. Mark

The instructions mention a straw assembly, does that come with it?

The product description specifically says two part? NO...???
Asked by: Anonymous
Hi OceanJeff40, there are two great stuff pro window and door sealants, One you use with a straw and the other one uses a gun for distribution of product. The one you are asking about uses a gun. The other type has a different valve on top and accepts a straw which screws on to the valve. The straw comes with that product. I know both installation guides, state to screw the straw on the valve. Hope that answered your question.

Is this PRO "high yield" Great Stuff formula actually higher yielding than the regular Great Stuff cans with the straws?

I'm trying to determine the cost per ounce of foam. The regular cans are 16 oz for about $6 and the PRO cans are 20 oz for $13. Unless there is actually a formulation difference resulting in greater yields from the same fluid ounces, I'm likely to buy the original cans with the straws as the are a better value for my project.
Asked by: DanFrontier
Dear Dan: Yes. Justin Fink at Fine Homebuilding ran a thorough test of Great Stuff. Here is what he found: Gun yield: 83 cubic inches per ounce Straw yield: 69 cubic inches per ounce Even more important, spritzing the foam with a bit of water boosted the yield by 73% (gun) to 92% (straw), accelerated cure time and created fewer voids in the cured foam. (The numbers shown above include the water spritz treatment.) That's because Great Stuff foam needs water vapor to cure, and pulls it from the humidity in the air. A light spritz of water improves the process. I hope this will be helpful in your next Great Stuff project! Mark

Do you have to buy the gun to apply the Window and Door sealant ?

Asked by: Braiden
Dear Braiden: No. Home Depot also sells Great Stuff foam in standard 16 oz cans with a built-in straw. No gun is required. See: Great Stuff Model # 248312, Home Depot Internet #100068117 Store SKU #522661 A couple of tips: Great Stuff foam pulls moisture out of the air to cure. You can significantly increase the volume of foam and improve the quality of the cured foam by simply spritzing it with a little water after you apply it. The 'Windows and Doors' version is also ideal to seal around windows and doors, foam board and other areas; the cured foam remains flexible to avoid cracks as things expand and contract. Two cautions: (1) Great Stuff sticks tenaciously to everything -- including carpet, paint, your hands, hair, etc -- and cannot be removed with any standard solvent. Wear gloves and tarp off anything nearby. (2) All versions of Great Stuff are very flammable. The cured foam will ignite at just 240 degrees F. So NEVER install Great Stuff near any source of heat, e.g. furnace ducts, recessed ceiling lights, etc. I hope this is helpful. Mark

spray versus batting insulation for storage building

I bought one of your 16 x 16 two story buildings for my home. I need to insulate. What is the coverage of your canned spray foam versus batting ; and cost per square foot of each?
Asked by: Anonymous
GREAT STUFF™ Products are designed to be a gap and crack air sealant. R-values are usually determined based on the entire wall assembly. Since this product is used in thicknesses of less than a inch, it considered more of an air barrier than a insulation. For can foam using the straw adapter, the theoretical yield of one-component foams are measured in lineal feet. For the 20 O.Z. can you will get approximately 417 linear feet at a 3/8” bead or 235 linear feet at ½” bead. If you need to insulate a wall, consider using Dow FROTH-PAK™ Class A polyurethane foam insulating system in cavity wall applications. Click the following link for more information on Froth Pak. http://building.dow.com/na/en/products/sealants/index.htm Another option might be STYROFOAM™ Brand Square Edge product with square edges on four sides to help ensure energy efficiency and minimize on-site cutting and waste. It offers superior water resistance, long-term thermal performance and high compressive strength for a wide range of applications. http://building.dow.com/na/en/products/insulation/squareedge.htm If you would like more information on any of these products, please do not hesitate to contact us at 800-441-4369.

Over the last 2 months I have noticed that a can doesnt go very far anymore. It needs to expand a little bit more. A can of Hilti foam lasts much longer.

Rated 3 out of 5 by from For the most part, a good product Great Stuff Window and Door foam performed well enough, but I've used other door and window products that did better. One thing I'm not sure about is that the foam stays pretty soft after curing. Trimming soft and spongy foam is not the easiest thing to do cleanly and accurately. Could be a good thing...may not? I was most surprised that about 3/4 the way through the can, the applied foam started shrinking back quite a bit and not holding or expanding its shape. Substrates and application were the same as the previous applications. For 3/4 of the can, I was happy enough, but think I'll go for a different brand if it is available.

Rated 3 out of 5 by from Check the date on the bottom! HD stores do not manage expiration dates on this product. In Feb 2016, one store had a couple of dozen cans with expiration date Jan 2015! Another store had only Feb 2016. Another store had cans dated 2017.

Rated 4 out of 5 by from Great product, but missing support The pro model of Great Foam is really much more usable than the cans in most cases, but HD doesn't carry all the necessary support products to fully use the system. When you pay good money for a pro tool you'd like it fully supported. HD doesn't carry all the pieces to do so, and I was forced to go to AMAZON to get the rest of the options, like cleaner and the other useful foams available for the system.
