dshall Posted October 12, 2020 Share Posted October 12, 2020 Hi Guys, Do you know of an Approval number for 1-hour wall (7/8" stucco & 5/8" type x on 2x4 @ 16). I know, we have been using this 1-hour wall since I was in diapers, but I have a plan reviewer who wants me to prove this and now I cannot the approval number, more busy work. Thanks 1 Link to comment Share on other sites More sharing options...
DRAWZILLA Posted October 12, 2020 Share Posted October 12, 2020 That's the way I have done it also. Nobody has asked me to prove it though. Good luck with this one. Maybe you could make his car payment for a year or so as a sign of good faith. Link to comment Share on other sites More sharing options...
dshall Posted October 12, 2020 Author Share Posted October 12, 2020 Thanks P., I have searched the internet and there is no clear answer but I have been doing this for longer than I want to admit. I remember I had to prove it once before and I don't even remember what I did. Here is one approved assembly but it too is not super clear. (per IBC Table 720.1(2),Item 15-1.3).

Yep, I think that's the one...but it's Table 721.1 You might place a call to the jurisdictions Fire Dept. plan checker... I usually find them to be very helpful Link to comment Share on other sites More sharing options...
Chief16Designer Posted October 12, 2020 Share Posted October 12, 2020 2 layers of 5/8 drywall = 1 hr fire wall check on that most of the inspectors don't pay attention to the 1 or 2 layers 1 layers = 30 min Link to comment Share on other sites More sharing options...
Alaskan_Son Posted October 12, 2020 Share Posted October 12, 2020 The real question here in my mind is: What even is an “approval number”? Link to comment Share on other sites More sharing options...

rlackore Posted October 12, 2020 Share Posted October 12, 2020 Maybe this could satisfy the inspector: https://stuccomfgassoc.com/wp-content/uploads/2020/06/One-Hour-Fire-Walls-Wood-2020.pdf Link to comment Share on other sites More sharing options...
DzinEye Posted October 12, 2020 Share Posted October 12, 2020 https://www.cement.org/docs/default-source/stucco/eb049.pdf?sfvrsn=540de3bf_2 See page 29 ... but I can't locate the darned document it refers to. This all used to be prescribed in the UBC back in the day... Link to comment Share on other sites More sharing options...

LOL I'm getting some very ridiculous corrections these days. I sure do miss the old days of drawing plans on a napkin for approval. However its good for the architect's to make money. All this red tape is another way to bleed money out of the people. California is the worst! Link to comment Share on other sites More sharing options...
