Research summary, not a hands-on test. Product claims on this page are attributed to the sources and dates shown. Before use, read the exact product label, the current safety data sheet and the application instructions, and confirm ventilation, protective equipment, occupant isolation and re-entry or reoccupancy conditions. A surface-burning classification alone does not establish approval to leave foam exposed or to use it in a particular assembly.

The claim, in the seller's words
"High yield foam sealant" for "wider gaps, joints and cavities." The sheet prints a UL 723 result on a plain gap filler, flame spread 10 and smoke developed 20, which is unusual. What the documents state
| Fire | DIN 4102-1 B3; UL 723 flame spread 10, smoke developed 20TDS rev. 1 |

| Pack | Net 24 oz / 680 g on the sheet; 12 oz listings exist on AmazonTDS and listings |
Our reading
Stanley publishes a full document set for this can, TDS and SDS, from its own documents page. What the sheet lacks is the one number a gap filler buyer wants, a gap width or a yield; "high yield" is the whole statement. The Amazon titles call it "spray foam insulation," which is the naming habit the coverage guide warns about: this is sold by the can, not by the square foot.
Still open
- The sheet describes a 24 oz can; the 12 oz listings are not separately documented.
- Amazon titles describe the can as "Polyurethane Spray Foam Insulation." It is a gap filler.

Each displayed price is what that listing showed on the date printed in its row; ratings were read October 29, 2026. A pack with no price is one where the listing showed none, where the figure contradicted another variant, or where its last successful read passed the freshness window. Prices are snapshots, each dated where it appears, not live figures, so check the seller before you pay.

Jobs where a can from this category is part of the answer
These pages name the category rather than this particular can. Each one sets out the constraint that decides the product for that assembly, the code section that applies, a worked quantity example, and where foam is the wrong answer.
- Attics As gaps and cracks foam. Top plates, wire holes, plumbing chases and the hatch perimeter are gap-filler work; Loctite Tite Foam and Kraken Bond Gaps & Cracks carry the clearest sheets.
- Rim joists As gaps and cracks foam. For the sill-to-foundation joint and the wire and pipe holes through the rim, before the surface foam goes on.
- Sheds As gaps and cracks foam. Sheds leak at the sill and the corners; the sealant goes on first.
- Metal Buildings As gaps and cracks foam. Every screw line, conduit, hydrant and vent through a steel skin is an air path. Sealing those is cheap and it is the part of the job that pays back fastest.
- Pole Barns As gaps and cracks foam. Every screw line, hydrant, conduit and vent through the skin is an air path, and in a barn the eave and the sliding door jambs are the big ones. Sealing those is cheap and it pays back fastest.
- Sound Control As gaps and cracks foam. The part of this job that reliably works. Outlet boxes on a shared wall, the gap where a pipe or duct crosses between rooms, the perimeter of a partition at the top plate. Cheap, checkable, and it removes the paths that make an assembly rating meaningless.
