We’re starting to renovate some basement rooms and the building code now requires a fire stop in the framing at the top of all wall cavities. Some of the outside walls are finished with sheet rock over styro board with nothing at all on top to act as a fire stop. Is there a way to add a fire block at the top or do all of these have to come out?

If you have the cavity behind the rock filled with styro, how can a fire updraft happen?..whatever.

Fire block or fire stop, b/c they are different? Maybe you can use a fireblock foam. Check with the inspector. See below:

Thanks for that link Billy. I'm forever trying to explain to others that there is a differnce between fireblocking (we use the term draftstopping) and firestopping . Now I can just print out the article and hand it to them!

Yep, most people look at me funny when I tell them there's a difference. That's a good idea to keep a copy of the article handy. You can just hand it to them and walk away.
