The building is fully sprinklered, so per CBC 3006.2.1 an unrated smoke partition is all that's required. Have any of you used storefront in this kind of application? Thanks Brian Payne Senior Member Username: brian_payne Post Number: 303 Registered: 01-2014 Posted on Wednesday, March 22, 2023 - 07:09 pm:    I went down this rabbit hole a few years back. No good news, but I’ll try to respond later with more info.

That is an expensive solution. Then there is the option to punt the problem: Use a totally standard (project standard or otherwise) door system and install a separate roll down smoke barrier in front of the door. Both systems offer fiddley solutions for emergency egress Curt Norton, CSI, CCS Senior Member Username: curtn Post Number: 254 Registered: 06-2002 Posted on Wednesday, March 29, 2023 - 09:15 am:    You will still need a system rated for smoke if you don't use the smoke curtain. (Honestly, the smoke curtain at each elevator door is my preferred solution) For our office, we used hollow metal frames and a wood door with a smoke rating. You would have to check with the storefront manufacturers to see if they offer smoke ratings.
