Horizontal Fireblocking?


Was just reviewing some stuff for an upcoming residential framing inspection for an addition I'm building on my home. Came across this:

FIRE BLOCKING
Blocking at 10 intervals horizontally and floor
levels vertically........................................ ........... IRC R602.8


Ok, I know about sealing penetrations, etc. And no 10' walls, so nothing of concern vertically. But how would you go about fireblocking the spaces between the floor joists? I used those I-beam style floor joists with the OSB web & microlam top & bottom flanges.

I was thinking to put in some 2x2 nailers vertically between the flanges and then screwing some 5/8" type X drywall across the nailers. But I'm guessing I will have to notch each corner of the drywall for the flanges so that it will fit tight against the webs? Assuming this will have to be caulked with fire caulk also?

Any tips appreciated!

Horizontal Fireblocking?


Ok, just re-reading this. Maybe it doesn't say what I first thought. Does this just mean that horizontal fire breaks are needed every 10' vertically?? In which case, I don't need any of this.

If you have ceilings over 10', you need to install fireblocking in the framed wall bays. There should be no open areas in your wall framing between the floors, in stairwells, or between your top living floor walls and the attic.

Think: Your goal is to eliminate open pathways or holes (that also allow O2 access) - inside of walls that can allow flames and intense heat, to spread quickly from one floor to the next. That is also the reason for fire-blocking caulk inside of electrical line holes bored in horizontal framing.
