How to fireblock framing

prican_2000

Thank you all!!!!

I am a Newbie and in the process of having my house built but I opted on not having my basement built and using those credits for other items in the house so I will be building my basement myself. I have read thru all 14 pages and at first I was a lil foggy about the whole Fireblocking concept (actually I didnt even know anything about it until I found this website) but it was not until I saw the pics posted by Barlav and hellonoko that it cleared it up for me. THANK YOU!!!!

I will ensure that I adhere to the Fireblocking regs posted here when I begin my Basement framing.

So I came across this thread a little to late I think. My framing is up and now I need some help on how to fire block it.

1. Dow Thermax Sheathing was already on the walls so I left it there and framed next to it. What do I do for horizontal fire-block?


2. Had to frame around waste pipe not sure hot to fire block.


3. Left space for HVAC return air in framing, I cut the thermOpan and found that the return air for the existing connection goes through the floor.


4. Lowered bathroom ceiling do I have to add blocking inbetween each stud right below where the ceiling drywall will be?


Thanks for any help

Im going to be finishing my basement soon and not sure if i missed it in the previous threads but my question is;

With the insulation in between the floor joists, do i still need to fire block at the top of the exterior walls or is this sufficient?

This is a great thread and I appreciate all the info. I'm adding a bedroom to my basement and fireblocking the soffit is still confusing me. From what I've read in this thread, it sounds like I only need to fireblock the soffit where it connects to a vertical wall, right? So I just want to confirm I DON'T need to put fireblocking where the joist canals meet the soffit like in the picture I posted. I don't need to put fireblock in the red area below, right? It just seems that if a fire started between the joists, I'd want to stop it from entering the soffit area.

Thanks,
Jon
