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 one product that belongs to both the gap filler and the fire block sets by its own description: a 3 in gun foam that is "fireblock formulated." It is also the best-known orange can in the trade. On Amazon it reaches buyers through a reseller rather than DuPont, in listings whose titles do not state the pack count, so the same "24 oz" title can be a single can at one price and a case at another. Read the listing body, not the title, before you compare prices.
Still open
- The 30 oz can sold on Amazon does not appear on the brand page, which lists 24 oz only.
- For fire block use the buyer needs the tested configuration and the index values. DuPont names the methods only; the complete version of such a claim, with file numbers, exists in the trade (Loctite publishes one for its Pro Gaps & Cracks Foam), so this is a publishing choice rather than a limit of the category.

Sizes and prices, latest read October 29, 2026
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.As fire block foam. Where a penetration between floors is a fireblocking location, the orange can needs a real surface-burning result; the fire block page sorts the claims.
- Garages As fire block foam. Penetrations through the separation wall are where a fireblocking claim is actually asked for.
- 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.
