Description
Closed Cell Spray Foam Insulation in a Can – Pro Results, No Tanks, No Mixing
Seal Spray Closed Cell Insulating Foam is the ultimate closed cell foam spray solution for sealing gaps, insulating walls and ceilings, and maximizing energy efficiency. With over 80% closed-cell content, an R-value of 6.45 per inch, and up to 25 board feet of coverage per 27.4 oz. can, it delivers two-component performance from a simple can – quick to apply and built for real results.
Unlike closed cell foam insulation options that require mixing two components out of large canisters, Seal Spray Foam is ready the moment it arrives. Attach the fan spray tip or the Angled Spray Foam Gun and apply insulating foam directly – vertically on walls or overhead on ceilings. Get professional results without the mess, waste, and expense of contracted spray foam installation or bulky two-tank kits.
Why Seal Spray?
R-6.45 per inch * – among the highest R-values of any one-component canned foam.
Note: 6.45 is based on two passes of 1/2 inch with skin left on (recommended) or 4.5 with one pass and skin shaved (not recommended form of application )
Up to 25 board feet per can – up to 25% more coverage than leading 20-board-foot competitors
Class A Fire Rated (ASTM E84) – Intertek tested: Flame Spread 15, Smoke Developed 150
Over 80% closed-cell content – seals out drafts, moisture, and noise in one pass
Fan spray application – coats surfaces like a pro rig instead of laying a bead like gap-filler foams
No tanks, no mixing – attach, spray, done; approved for multiple passes to build R-value
Safety You Can Verify
Seal Spray Foam is Class A fire rated (ASTM E84) and Intertek tested, with a Flame Spread of 15 and Smoke Developed of 150. The full Intertek fire test report, technical data sheet, and safety data sheet are available in the Documents tab.

Whether you're sealing a drafty rim joist with a single can or insulating a whole metal building with a 24-can kit, Seal Spray Foam scales to the job – and costs significantly less per board foot than large-format two-component kits.
How Much Foam Do You Need?
Each 27.4 oz. can covers up to 25 board feet (25 sq. ft. at 1" thickness). Multiply the square footage of your project by the thickness you want in inches, divide by 25, and add a 10% buffer – that's how many cans you need. Or use our coverage calculator below.
Estimates assume up to 25 board feet per can under ideal conditions and R-6.45 per cured inch. Temperature, humidity, substrate and technique all affect real yield — order a spare can for anything beyond a small patch.
The perm rating is less than 1 per 2" based on closed cell content with skin on and when bound to natural porous substrate.
I want to fill a volume below a refrigerator box. What is the max thickness recommended with your Seal Spray High Performance Closed Cell Insulating Foam Can
Question by:Brian Penrod
There is no maximum thickness that is recommended for this product. This product can be sprayed as thick as you wish but is designed to be sprayed in layers, each layer not exceeding .5". In order to achieve maximum results the foam should be allowed to cure before spraying additional layers. Spraying foam too thick in too little time will result in less yield.
So, is the R-value 4.37 @ 1” thick? Can it be used to insulate ductworks located in the attic that can probably reach over 120F? Because it says max service temp is 87F, does that mean if the temperature is over that rated temperature the foam is useless at insulating?
Question by:Mr.roboto
The max service temperature listed is for the application process only and does not reflect the properties of the foam once cured.

Pricey but works pretty good.
This stuff is great once you get the groove of applying it. Very easy to apply on walls but a little more difficult on ceilings and angles. Definitely watch the video. Customer service was 5 star.

Excellent new foam option with LOTS of use cases
This type of foam has been available in overseas markets for a while, I was thrilled to see it finally available in the US.
Although they are different, it would be best to compare this to the 2-tank spray foam kits than to the rest of the "can" foams out there, because the defining feature is the projecting fan-pattern spray, as opposed to the "bead" of all other can foams. This is a must if you are trying to cover the surface of something with an inch or two or more of foam.
It _doesn't_ replace the 2-tank kits. For larger projects, they are still the right choice. But there are MANY smaller projects that might not be worth using a kit where this would be ideal. (Also, the smallest two-tank kits don't have fan tips anyway, so they are better for gaps and cracks than covering the surface of something.)
They sell this up to a roughly 600-board feet kit (24 cans) and I would probably go that far with it. More than that, and I'd likely get a couple tank kits. But where it REALLY excels is smaller projects where you might only need a couple 2 or 3 cans. The tank kits are a horrible choice for that, and this is a perfect choice.
My takeaways:
1) The foam from 2-tank kits is much more rigid when cured. This 1-component foam is basically the same as all other 1-component foam once cured. It is very firm, but does have a little bit of a rubbery "give" to it if you push on it. Not as much as most "Window and Door" versions of foam, more similar to most brands "general purpose" version. This isn't a bad thing, it is just a difference. But the rigidity of 2-tank foam is often touted for how much it stiffens up a wall. Just don't expect the same degree of rigidity from this 1-component foam.
2) Like all 1-component spray foams, this cures from moisture/humidity in the air. It will expand more and cure faster if you _very_ lightly mist it with water. This is totally not necessary (unless you are in a super dry area) but is a common property of all 1-component foams.
3) Because it is a moisture cure, it is not "fast" like the chemical cure 2-tank kits. If you've ever used Great Stuff (or comparable) you know exactly what to expect time-wise. I personally wouldn't aim for a thickness of more than 1-1.5 inches in a single pass, or it might start falling off. And you need to give it significant time to cure before you lay down a second layer. I would give it BARE MINIMUM an hour. Because the second layer will cut off air/humidity to the first layer, you want it to be done before you cover it or the first layer may not finish curing properly. Claims of "minutes to cure and recoat" are confusing this type of foam with 2-tank chemical-cure kit foam. You will ruin your foam if you try and re-spray it within 5 or 10 minutes.
4) This slower cure can actually be a benefit in many cases and I am looking forward to using it to my advantage. You can spray it, and then replace the drywall/sheathing/whatever and just let it cure behind the surface. No need to worry about trimming off excess, because you have PLENTY of time to finish spraying, and then replace the wall covering. (Make sure there is still some airflow, and that you didn't spray SO MUCH that it would then bulge out the wall. That's easy to do with regular can foam in gaps and cracks, which is why everyone makes a softer and lower expansion "Window and Door" version, but wouldn't be as easy with this. But it is still possible if you go crazy.)
5) The cans go FAST... But if the board-feet yield is accurate, you are buying it based on the price vs. board feet, not the number of cans it takes to get those board feet, so just be aware. (I can't speak to the board feet yield accuracy, because I've not done "scientific" enough tests to say. And there are so many factors that go into it.)
I wholeheartedly recommend this for many types of fan-spray foam projects. It is just important to recognize that it is not an exact substitute for the 2-tank kits. I would say they are pretty interchangeable in the vast majority of projects (size dependent) but not necessarily all. If you really need the rigidity of the tank foam, this won't give you that. Also, the tank foam does have a bit higher R-values. If you are going for a specific R-value, you'd need to factor in that you'll need a thicker coating of this (therefore more product) than if you used tank foam. If you're just going for "some insulation and a moisture/vapor barrier" I would say that's not an issue.
Thanks for bringing this to the US, Industrial Products!
