Glenn Your video is awesome. thanks for the explanation.
Thank you for your thorough explanation. I have been in construction for years and there is always something to learn.
This was SO helpful! We purchased a home where the previous owner had begun to finish the basement, but had stopped at the four-way. I called the city and a four-way inspection had been done, but had failed the “draft blocking.” I had no idea what that meant. After much research, your video has been the single most helpful and instructive source of information I have found! I now know what I need to do. Thank you so much!
ProVisionColor thank you for the kind words. For my complete course and more videos in basement finish, check out the class Building Codes for Basement Finish at www.buildingcodecollege.com. You can take one course free with coupon “welcome”
Wow! I'm a DIY person and I am finishing my basement. I had a construction person come to install a Egress Window where there is going to be a bedroom. H had mention to me to make sure I do the fire blocking. He said he will show me what that meant. So I look it on "RUclips" and came across this outstanding video. Now I understand what I need to do because I want to do it right. Thanks for the Video. :-)
One thing I would caution everyone about with the "Great Stuff" fire blocking foam or any other foam, is that it has a modified UL testing....key work MODIFIED!! Many states and local jurisdictions will not allow these types of products for fire blocking or stopping. I have experimented with these products and they will ignite and free burn with a lighter or match. I would recommend a quality fire caulk ( with a UL, OR ASTM listing), or the other mentioned practices. I am from Indiana, we have some of the least stringent fire and building codes due to our wonderful state amendments, and the state still prohibits the use of "foam in a can", even if it's advertised as a fire blocking material. As a Local Fire Official I educate my customers on the safest practices for fire blocking and stopping. -Keep the public safe through fire prevention education and enforcement...Stay safe!
Thsnk you. This was a great explanation of fireblocking. Now I will be much more confident finishing my basement and passing inspections first try.
thank you so much for your video Glenn. Very thorough in explaining this very important topic. thank you for sharing with us.
Awesome video! Really useful, direct information with clear examples. Keep making these
Sometimes you have to sell the idea that fiberglass insulation is a fire block. Many inspectors won't accept it. For them, wood is the only block because of the burn-through time. However, adequate fiberglass prevents the TRAVEL of fire through a cavity.
Thank you for posting this video!!! It was very informative!!!
One of the better fireblocking videos I've watched. Thanks
Thanks for sharing. Yes it would be very important to understand fireblocking and draftstopping which can be misunderstood without close examination of the code . The code is more permissive for single family dwellings and more restrictive for multi-family and commercial construction. Thanks again.
Great video Glen ! I would like to add a frequent error I find in the field where ATS rods penetrate rim joist often it’s a misconception in the field to caulk the seismic rod. This ofcourse is nonsense and counterintuitive being that they settle and move with oscillation over time in turn moving the caulking. Properly installed and rated insulation is the best practice there. Occasionally you will find a good set of plans calling that out by the structural engineer but often it is not. Great video 👍🏾
hi glenn, this was super informative. I'm undergoing a basement renovation and following the 2018 VA residential building code. One question I do not understand is whether fire blocking is needed in the ceiling joists of a basement? What if HVAC ducting or electrical runs down the length of a ceiling joist bay? I haven't been able to find clarity around those questions and the county inspector isn't providing direction.
Hardie backer board I think would be the best to use for stopping fire. It won't burn and keeps its strength
Well done thanks!
thank you for this information. can you show fire blocking under stairs, and above a soffit built to enclose HVAC ducting?
Well done!
Glen thank you for your knowledge and fine work. I have a question about fire blocking my basement and the use of rigid foam insulation? I have 1 inch eps foam tight to the concrete foundation wall then 2x3 wall studded tight to that, the cavities will then be fill with unfaced insulation and then drywall. do I need to put fire blocks through the foam and to the foundation wall as if the foam was not there?
Great video! Would 5/8” drywall be accepted and simply above code standards?
Thank you for the video it was very helpful picture gathering on your part.
What about the fireblocking between garage and ajacent room/other rooms, and garage and 2nd floor living space?? How does that work?
thank u
Awesome information
Is there any mention of sheet metal as fireblocking in code? It's used to fireblock around flues, so it must be effective to block draft...
Sounded like Adam carolla at the end!
Hey Glenn your videos on fireblocking are really helpful! In the example at 9:41 does the OSB have to extend all the way to the front edge of the stud wall? Could PT 2x6 be used in the same way?
This is so very fantastic and clear instructions... Thank you so much...!! And when you are you posting the updated version....? :)
Thanks. Well, I've been so busy with other new videos, I haven't circled back around to this one yet. Check out my online school for lots more education, www.buildingcodecollege.com Use coupon code "welcome" for any one free individual course.
Well the beauty of the electronic world is my work can be changed overnight. Quite a difference from my days as a contractor. I've gotten some great feedback from this first recording, and I am looking forward to it's next version. Here are some errors and clarifications I will fix:
1) What a dummy! It's not 22/32 OSB, it's 23/32! Oops! Truthfully, while recording, I kept wanting to just say "3/4" osb, because that's what everyone calls it. Sorry for that error.
2) In a few photos of 7/16" osb used for fireblocking the horizontal wall cavities, it is not cut tight. The gaps around the OSB would need to be filled. Typically packed fiber or mineral wool fiberglass would be used, or approved fireblocking foam. Where the gap is too big, solid fireblocking would be necessary, or filling the whole cavity with insulation, as discussed. I'll clarify that in the next recording.
Thanks for all the feedback, keep it coming. Quality education is all that matters, so your help is welcome!!

Is there a way to propery install vertical fire blocks after XPS insulation has been installed against cinderblocks with all seams taped.
Glenn, I just framed my basement wall right snug up against the concrete basement wall. Do I still need a fireblocking? There is only an inch gap between the top concrete wall and the stud plate
Somewhat unique situation I'm looking at. Basement will be outfitted with drop ceiling ... If rock wool / mineral is installed fully across the basement ceiling and properly jam packed as well at the edges to the rim joist... Do I still need to put in a layer of plywood/osb at the sill plate level to act as a vertical fire block?
Also, if rock wool, is in the ceiling above an air duct (no soffit for the duct), does that work as well for vertical fire blocking?
nothing easier that 1/2" drywall
Is there a reason we denote 22/32" OSB instead of 11/16" ? I'm a furniture maker turning to construction work and was curious about this measurement.
I think he means 23/32, you can buy that at HD. 22/32 I wasn't able to find. I suppose anything greater than "22/32" passes inspection.
Great tutorial. What I still wonder is why my plumber was ordered to fire caulk around every pipe that passes thru every floor joist in the kitchen. That's a horizontal space, does not communicate to other floors. Any comment about blocking within the framing of a floor or ceiling? Left - right?
Many inspectors do not understand fireblocking. That's my best guess.
can you use two 7/16" osb a a barrier
He said in the video at 5:25 no you cannot.
I think so, so long as the joints are staggered.
The main question to keep in mind is that” what is the material rated?” Or is it “rated?
@@TRX450RVlogger At 5:25 he actually only said the 7/16 is not acceptable, nothing about two layers. If it's doubled for 14/16, then that's greater than 22/32, or so the argument goes. Local codes may allow it.
