Sprayman Pro Fire Block Foam
Class A on the store, B2 on Amazon, and one undated sheet that prints both.
2 of four things confirmed
These are the four things we could check for a fire block can, and nothing else. Not a performance score: nothing on this page was applied or tested by us. How the fire block page is ordered.
- Brand data sheeta technical data sheet is published by the brand, without a date or revision on it
- Claim checkableThe document that reconciles the two labels exists and still does not earn the mark. It prints a surface-burning pair under UL 723 and a reaction-to-fire class under DIN 4102-1, with no tested thickness, no report or file number and no date. This category asks for a fireblocking result, which is a different test, and no Sprayman document answers it.

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 same can is described as Class A on the brand site and B2 in the Amazon title. Those answer different questions: Class A is a US surface-burning result under ASTM E84 or UL 723, B2 is a German reaction-to-fire class under DIN 4102-1, and one product can hold results under both. The maker's own sheet prints exactly that: UL 723 flame spread 10 and smoke developed 15 on one line, DIN 4102-1 B2 on the next. The two channels are each quoting a different half of the same sheet, not contradicting each other. What is missing is the thickness the surface-burning sample was tested at, a report or file number for either result, and a date on the sheet. And neither result is a fireblocking result, which is what this page marks.
Still open
- The sheet carries no tested thickness, no report number and no date.
- No fireblocking test is published for this can, which is the test this category asks for.

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.

Can the fire block claim on this can be checked? From the records
