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 gun version of the F952 is documented, but its sheet drops the UL 723 line that the straw sheet carries and replaces it with "moderate fire safety." We read that as honest and as a reason not to assume the two cans share a test result.

Still open

  • No UL 723 or ASTM E84 figure on the pro sheet.

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 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.
