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
Generally , no. Its cheaper than the •ASTM E814 / UL 1479 approved stuff, but don't risk it. Use ABESCO FP200 for fire rated seals.

12 oz. Fire Block Foam is rated 3.3 out of 5 by 10.

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.

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 5 out of 5 by from Very good product Easy to use, performed as expected. Expands more after a while.

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!

Rated 3 out of 5 by from Works well, but don't get it on you This product does the job it was designed to do. It expands greatly when dispensed, so be conservative when using it. Unfortunately, the warnings about getting it on your skin are in fine print and not clear enough. I got some on my hand and had a terrible time getting it off--very sticky--hardens very quickly. Using water and dishwashing detergent for over an hour, I managed to peel it off little by little. WEAR GLOVES.

Rated 4 out of 5 by from Foam It Does what it is supposed to do fills in the areas around pipes and other holes that need to be blocked. Very sticky so protect areas in case it drips, remember that it expands so don't over fill and wear gloves.

Rated 5 out of 5 by from FIRST TIME USE, BUT MUCH BETTER THAN CAULK GUN. FIRE BLOCK FOAM DID THE JOB AS EXPECTED FOR A 2600 SQUARE FOOT BUILDING BUILT AROUND 1920, ONLY NEEDED 5 CANS. THIS COMMERCIAL BUILDING PASSED ROUGH INSPECTION WITHOUT A PROBLEM.
