Anyone got the verbiage about fire barrier installation between multi-family attics on a structure built in '94? Wondering specifically if joints and edges have to be taped and mudded? Thx.

Hi to all,


Brandon I don not have the full UBC text with me but I believe that it falls under 709.7 and taping is required.

regards

Gerry

UBC 310.2.2 = 1 hr. construction at common walls & floor/ceiling for multi-family dwellings, two-family dwellings and townhouses.


UBC 708.3.1.2.1 = Separation walls to extend in parapet above roof OR common attic spaces sprinklered OR divided by draft stops & returns above separation walls.

Sealed gaps are addressed under UBC 708.2.1

UBC 709.7 deals with electrical boxes in separation walls.

Thanks guys, but to simplify, and if you happen to know: Do joints and edges in the attic firewall require taping an mudding?

Yes. Otherwise, it wouldn't be considered "one hour construction."

I had this same question a few weeks ago while inspecting a condo. I contacted my local AHJ and a fire inspector informed me that No, the joints do not need to be taped/floated if the gap is 1/4" or less. That’s just my local jurisdiction so I’d recommend checking with your own.

I think part of the confusion arises (at least for me) when trying to determine the difference between a ‘fire wall’ and a ‘draft stop’. I agree with all of the above statements regarding taping of fire rated assemblies used as true fire walls. I am also thinking that what I see in older condos is a ‘draft stop’ which requires different, less stringent construction methods. Unless one has the original construction drawings to determine whether a true fire wall was called for then it’s a hard call. Someone tell me I’m full of it, thank you.
