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 expansion rate." "Fixing and insulating window and door frames." Both statements appear on the same data sheet; Kraken also sells a separate low-expansion Window & Door Pro foam. What the documents state
| Expansion | High expansionTDS rev. 2 |
|---|---|
| Yield | 8 to 12 gal volumetric yield (ASTM C1536); density 1.37 lb/ft3 (ASTM D1622)TDS rev. 2 |
| Thermal | About R-4.1 per inch, stated alongside 0.036 W/m.K to DIN 52612. The FTC rule at 16 CFR 460.5 names four US methods, three of which are conductivity measurements, so the objection is not the method type: DIN 52612 is a German standard that is not one of the four, and no aging basis is given. Taken on its own the 0.036 figure works out at R-4.01 per inch, so the two numbers on the sheet are close but not derived from each otherTDS rev. 2 |
| Fire class | B3 to DIN 4102, the lowest German class; no US surface-burning figureTDS rev. 2 |
| Working range | Application 28 to 86 F; tack-free 7 plus or minus 3 min (ASTM C1620)TDS rev. 2 |
Our reading
The most complete gap filler sheet in the intake alongside Loctite, and the only one to print a volumetric yield with the method behind it. The same sheet describes the foam as high expansion and lists fixing and insulating window and door frames as an application, while Kraken separately sells a low-expansion Window & Door Pro foam. That is not a conflict between the listing and the sheet; it is an unresolved product-selection question inside the maker’s own range. The single 24 oz can also carried the same price as the 12-pack, $149.99 on September 7, so check the selected pack before ordering.

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.
1 of the 5 listings below showed no purchase option on October 29, 2026, so they carry no price.

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.
