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.

Our reading
The category reference product for most US buyers, sold on Amazon by DuPont itself. The 20 oz "157911" listing carried 1,911 ratings and a "500+ bought in past month" badge on September 8, while the brand page lists only the 12 oz can, so the larger can is a marketplace item you will not find described on greatstuff.dupont.com. Everything the brand says about performance sits on a web page rather than a data sheet; that is the gap in an otherwise easy record.
Still open
- The 20 oz can (item 157911) is not described on the brand site; its gap limit is assumed to match the 12 oz can and has not been confirmed.

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.
