Questions & Answers

Is this foam commercially rated to where I can use it in a office building?

Asked by: buildingtech
Dear BuildingTech: No. Despite the "Fire Block" name on the can, this 3M spray foam will ignite at just 240 degrees F -- significantly lower than the ignition temp for wood studs. The same is true for Great Stuff Fireblock foam. Neither are rated for a fireblock assembly, and should never be used near a source of heat -- e.g. recessed lights, exhaust vents, furnaces, etc. Both are banned as a fire stop in commercial construction. We typically use true fire barrier caulk, e.g. 3M Model # CP-25WB+, Home Depot Internet #100166701 Store SKU #163096. For larger gaps, we pack the gap with Roxul rock wool, then cover the surfaces with 3M caulk. I hope this is helpful, Mark

what is the hour fire rating on this product?

what is the hour fire rating on this product?
Asked by: J46
Dear J46: Despite the "Fire Block" name on the can, this 3M spray foam will ignite at just 240 degrees F -- significantly lower than the ignition temp for wood studs. The same is true for Great Stuff Fireblock foam. Neither are rated for a fireblock assembly, and should never be used near a source of heat -- e.g. recessed lights, exhaust vents, furnaces, etc. Both are banned as a fire stop in commercial construction. Residential building inspectors are becoming more aware of the flammability problem and may fail inspections where foam is used to seal penetrations, e.g. holes cut for plumbing or electrical lines. We always use true fire barrier caulk, e.g. 3M Model # CP-25WB+, Home Depot Internet #100166701 Store SKU #163096.

Can this foam be used around a vented gas fireplace flu?

Asked by: An
Dear An: No! Despite the "Fire Block" name on the can, this 3M spray foam will ignite at just 240 degrees F and should never be installed near a source of heat, e.g. your fireplace flu. 240 degrees is significantly lower than the ignition temperature for wood studs. I hope this is helpful. Mark

12 oz. Fire Block Foam is rated 3.6 out of 5 by 19.

We’re rehabbing a home and our plumber/electrician didn’t fire caulk any top and bottom wall penetrations. It was up to me to do that. It’s OK…but on a couple of cans, I broke the straw before even using the can…which was bad.

If you're a first time user please practice a little with a shoebox or something, don't do what I did. Once I got the hang of it the foam worked perfectly. You can even be a little sloppy and fix it up with a pocket-knife. Glad I found it.

This may be used to supplement fire rating of existing walls or I would recommend this stuff for general blocking fumes (garages) and air in risky areas. Be aware it is NOT fire rated. I.e. when walls must be 1-2 hr, rated for multi family, it wont pass. Fire rated stuff is pink, one is made by ABESCO, FP200. Check w/ your code enforcement. and make sure it has ASTM E814 / UL 1479 on label.

Rated 1 out of 5 by from Check with local Building Official First! Be very careful using this product. The can says it meets all codes, but my local building official made me dig it back out and use the caulk because they require a product with a listed 4 hour fire rating which this product does NOT have. Trust me, it's not worth it, just use the red fire block caulk instead!

Even with trying to keep the can in the correct angle most of the time, it blew through propellant and left me with a half can of uselessness. Other products work at any angle, I wish this one stood up to finishing the job.

Rated 4 out of 5 by from As expected, 3M products never let you down. "Great Stuff"... As expected, 3M products never let you down. "Great Stuff" spray foam (fire block & regular) have cheapened yheir product. Spout broke off several cans and cannot be re-attached. Stick with 3M, much better product!!
