Compare ounces, not claims
When two kits both say 480 board feet, the honest comparison is the total ounces you are being sold and the price per ounce, because those parts are published and real. Our value page does that arithmetic across the set.
Best by product and goal
Best Spray Foam Coverage
Coverage is the number every seller leads with and the one almost nobody stands behind. This page puts every claim in the set next to the document it lives in, and does the division the packaging does not.
Our file holds no independent field-yield test for any of these products; every figure is the maker's claimed or theoretical output under its own stated conditions, so nothing on this page ranks products by how far a can goes. What it ranks is how well each one documents the claim: whether the figure names a thickness, whether it lives in a dated document or only in a listing title, and whether the maker says what the number means. 4 of the 8 canister systems define their yield in print, from 2 of the 4 makers. 3 of the 11 single-can kits state theirs in a dated data sheet rather than a listing.
A coverage figure has to name four things before it can be compared.
A quantity. A thickness, or a unit that implies one. A document with a date on it, rather than a title someone can edit. And a basis: is this what a can produced in a laboratory, or what it produces on a wall? Most of the claims below name one or two of the four.
Single-can kits
The same output claimed for every can size
Sorted by whether the claim is in a dated data sheet, then by claimed output per ounce. The last column is the one the packaging never prints.

Read the last two columns together. The cans in this table run from 25.4 oz to 36.6 oz, a spread of 44 percent in what you are actually sold, and the claimed output a can barely moves. On the sellers' own figures the claimed output per ounce therefore varies by 44 percent across the set. That is not a measurement of which foam goes further. It is the shape you get when a number is copied across a category instead of measured in it. Every claimed output here is stated at a 1-inch layer, which is the only basis the whole set shares, and at 1 inch a board foot and a square foot are the same area. Double the thickness and the area halves. The R-value column is brought to the same basis: where a maker publishes a figure at 2 inches it is halved, and the row says so. BEEST FullStop publishes no net contents in text on any channel; the 26.8 oz used here is read off the can label in the maker’s own product photograph. Adhesive Guru QuickCoat states 32.8 oz a can without saying whether that is net or gross, so its ounces may be a gross figure and its per-ounce column is read with that in mind.
Canister and hose systems
The only makers who say what their number means
Same claim, but here some of them define it. A maker who prints what the figure rests on has told you more than one who prints a bigger number.
| System | Cell | Claimed yield | How the maker defines it |
|---|---|---|---|
| DuPont Froth-Pak 200 Foam System | Closed | 200 sq ft at 1 in | "The theoretical yield has become an industry standard for identifying certain sizes of two-component kits. Theoretical yield calculations are performed in laboratory conditions, without taking into account the loss of blowing agent or the variations in application methods and types." |
| DuPont Froth-Pak 630 Foam System | Closed | 630 sq ft at 1 in | Same theoretical-yield definition as the 200 |
| DuPont Froth-Pak 12 Spray Foam Sealant Kit | Closed | Not stated on the Amazon listing we read; the frothpak.dupont.com products page lists only the 200 and 630 | None found |
| Stanley F994C SuperCoat Canister Foam 200 and 600 | Closed | Up to 200 board feet, or 600, at 1 in | "Covers up to" on the retail page; no theoretical-yield definition |
| Vega Bond V200, V400 and V600 Closed Cell Kits | Closed | 200, 400 or 600 board feet at 1 in | "Covers up to" on the store; no definition of the figure |
| Vega Bond Open Cell Spray Foam Insulation Kit | Open | 320 or 1,100 sq ft | Stated as coverage; thickness not stated on the store |
| HandiFoam FR (HFO) II-200 and II-600 | Closed | 201 and 601 board feet | "Yield is based on free-rise density ... Applying foam into a cavity may result in higher in-place densities due to packing effects. These higher densities may result in lower yields." |
| HandiFoam Low Density (open cell) II-250, II-450 and II-1350 | Open | 250, 450 and 1,350 board feet | Free-rise density basis with the same packing caveat as the FR sheet |
Foam sealants
17 of 43 publish a yield, in 4 different units
A sealant is not filling a cavity, so board feet is the wrong unit for it. The trouble is that the makers who do publish something have not agreed on what the right one is.
| Product | Unit | What the sheet says | Source |
|---|---|---|---|
| Loctite Tite Foam Gaps & Cracks | Length of bead | About 134 ft of 3/8 in bead per 12 fl oz can, stated as a theoretical figure | TDS |

| TYTAN Professional Fill All | Other unit | The same table prints 502 ft for a "1/2 in width bead" and 1,463 ft for a "1/2 in bead". It describes the 1,463 ft figure as a theoretical calculation from free-foaming yield under internal method RB/024, but does not reconcile the two 1/2 in rows | TDS 08.06.2026 |

| TYTAN Professional Fire Block Extreme | Length of bead | 1,450 ft of 1/2 in bead from the 24 oz gun can, 80 to 110 percent post-expansion; 389 ft of 1/2 in bead from the 12 oz straw can | TDS 27.02.2026 and 24.02.2026 |
| Kraken Bond PestSafe Foam Sealant | Length of bead | 1,300 linear ft of 1/4 in bead from 13.5 fl oz | TDS 5.14.2026 |
| Akfix 892 Black Foam Sealant & Adhesive | Volume, ASTM C1536 | 7 to 11 gal (ASTM C1536); expanding volume up to 30 percent | TDS rev. 01, 2017 |
| DAP Touch 'n Seal Black Foam Sealant | Length of bead | 2,230 linear ft of 1/4 in bead per can (ASTM C1536) | TDS 11/14/2023 |
| TYTAN Professional Black Spray Foam | Length of bead | 1,450 ft of 1/2 in bead from the 24 oz can, 80 to 110 percent post-expansion | TDS 24.02.2026 |
| Kraken Bond ThermaFoam Wide Spray | Board feet | 10 board ft at 1 in per 16 oz can; recommended total thickness 2 in | TDS rev. 2 |
| DAP Wall & Cavity Foam | Board feet | Up to 11 board ft per can, theoretical; foam expands up to 3x, printed on the sheet as ASTM C1643. We cannot match that designation to an expansion or yield method; C1536 is the aerosol foam yield standard | TDS |
Every one of those figures comes from the maker's own sheet or listing named in the last column, and not one of them can be put in a column with another. A length of bead at a quarter inch, a volume in gallons to ASTM C1536 and a board foot figure are three different measurements of three different things. The other 26 records publish no yield at all.
Figures read from each maker's data sheet and store on October 29, 2026. Where a sheet gives a range we print the range.
What to do with it
How to buy against a number nobody measured
Work your own job first
Board feet are square feet times inches. Measure the area, decide the thickness, multiply, and then compare that number to what a kit claims. The calculator does it for you and the project pages carry a worked example each.
Then plan on less
Two makers say in print what their figure rests on: DuPont calls it a theoretical yield calculated in laboratory conditions, HandiFoam bases its on free-rise density. Buyers of every brand in the set report falling short, and the pattern holds under kits rated 4.4 as well as 3.1. The buyer reports set out what the complaints are about.
Questions
Coverage, answered from the records above
Which spray foam covers the most?
On the sellers' own figures, every single-can kit in the set claims about the same output a can whatever size the can is, so the honest answer is that the claims do not separate the products. What does separate them is the arithmetic underneath: divide the claimed board feet by the ounces you are actually sold and the claimed output per ounce varies by 44 percent across the set. That is a gap in the claims, not a measured difference in the foam.
Is board feet the same as square feet?
Only at one inch. A board foot is one square foot at one inch thick, so 480 board feet is 480 sq ft at 1 in, 240 sq ft at 2 in and 160 sq ft at 3 in. A seller quoting square feet without a thickness has given you a number you cannot use, and a seller quoting board feet has given you one you can, as long as you do the division yourself.
Why do sealant cans not state board feet?
Because they are not filling a cavity. A gap filler is measured as a length of bead at a stated diameter, and a few makers publish a volumetric yield in gallons to ASTM C1536 instead. Of the 43 sealant records here, 17 publish a yield at all, and they use 4 different units between them, so the category cannot be lined up in one column.
Does anyone publish a measured yield?
Our file holds no independent test of what a can actually produced under stated conditions, and the makers publish claimed or theoretical figures rather than field results. Two canister makers do the next best thing: they print that the figure on the box is a laboratory or free-rise number and that in-place density, packing and blowing-agent loss reduce it. That is a smaller claim honestly made, and it is the most useful sentence in the category.
Every figure on this page is rendered from the same records the product pages use, so the two cannot disagree. Nothing here was measured by us.
