Product Overview

3M Fire Block Foam FB-Foam is a ready-to-use foam firelock designed to help prevent the spread of flames and smoke in residential Type V and commercial non-rated construction. This product is intended to resist the free passage of flame and the by-products of combustion within the concealed space of a floor, ceiling or wall cavity by restricting the movement of air, fire and smoke. Also acts as a draft stop to restrict air infiltration and movement. Meets current fire blocking sealant requirements of the International Building Code (IBC) and International Residential Code (IRC) and state and local codes based on the IBC and IRC. 3M Fire Block Foam FB-Foam is recognized as a requirement to the methods prescribed by IBC and/or IRC codes for maintaining the integrity of penetrations of fire blocking and for draft stopping.

Customer 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

Can I use in commercial buildings to put around cabbles whit less voltage than electric cables

Dear Richie: 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.

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.
Rated 3 out of 5 by from I’ve bought plenty of these in the last month or... I’ve bought plenty of these in the last month or so. 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.

"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!!
