3M 7010401353 – Frequently Asked Questions
1) Does 3M FB-Foam fire block foam meet code for fireblocking in residential framing?
3M Fire Block Foam FB-Foam meets International Building Code (IBC) and International Residential Code (IRC) fireblocking requirements, and it has been tested as a Type V residential fireblock to ASTM E 84 (modified). That is the combination an inspector looks for when you are sealing penetrations through top plates, sole plates and stud cavities in wood-framed construction.
2) Is fire block foam the same thing as a firestop sealant for a rated wall assembly?
No, and this is where people get in trouble. FB-Foam is a fireblocking product, tested as a Type V residential fireblock to ASTM E 84 (modified) and meeting IBC/IRC fireblocking requirements. Fireblocking slows the spread of fire and smoke through concealed framing cavities. A penetration through a fire-rated wall or floor assembly is a different requirement and calls for a firestop product tested to the assembly system, not a fireblock foam. Use FB-Foam for concealed stud and joist cavities, plate penetrations and draft stopping.
3) Will 3M fire block foam stick to concrete and metal, or only to wood framing?
Adhesion covers concrete, brick, metals, wood, plastic and cable jacketing. That last one matters for electricians: the foam bonds directly to the jacket of cable running through a bored plate, so you get a seal around the cable itself rather than just around the hole.
4) How big a gap will one can of FB-Foam fill?
Each can holds 12 fl oz (354.882 ml) and the foam expands up to 200% in volume as it cures, so the dispensed yield is roughly triple the liquid volume in the can. It is sold six cans to a case, which is the usual buy for a crew working a floor of penetrations rather than a single patch.
5) How long before I can trim or cover 3M FB-Foam?
The foam is tack-free in about 5 minutes, so you can move down the wall and come back to shave the excess without waiting out a long cure. It is ready to use straight from the can with no mixing.
6) Can fire block foam be used around a hot flue or chimney chase?
FB-Foam is heat resistant up to 240 F (115 C). That covers normal concealed-cavity service temperatures, but it is not a high-temperature product for direct contact with flue pipe or appliance vent surfaces that run hotter than that. Check the surface temperature at the point you plan to seal before committing to it.
7) Does 3M fire block foam do anything for air leakage and energy code?
It acts as a draftstop to cut air infiltration, and the cured foam gives a typical R-value of 4 to 5 per inch (25.4 mm). So one pass at a plate penetration handles both the fireblocking requirement and the air-sealing detail a blower-door test is going to hunt for.
8) Will the foam shrink back and open up the seal after a few months?
The formulation is described as minimal shrinkage and sag resistant, which is what keeps the bead in place in an overhead or vertical cavity instead of slumping out of the joint before it sets. That is the difference between a fireblock foam and a general-purpose gap filler.
9) Why is fire block foam orange instead of the usual yellow?
FB-Foam is orange, and the color is functional. An inspector walking a job can identify a fireblock-rated foam at a glance and tell it apart from standard window and door foam, which is what keeps a penetration from getting flagged on a rough-in inspection.
10) What is the 3M part number for the 12 oz orange fire block foam case?
Order it as 3M 7010401353, the Fire Block Foam FB-Foam in orange, 12 fl oz can, packed 6 per case. That MPN is the case pack, not a single can, so a one-can requisition is the wrong line item.
