We need a 1 hour vertical enclosure system at a storefront glass (no mullion). We need it to have min. 55 stc too.
Thanks for your firestop request. To treat a joint between a vertical fire barrier and non-rated aluminum curtain wall, generally we can provide Code Evaluation Detail, CED, based on the code language in IBC section 715.4.2. This detail will be subject to the approval of the Authority Having Jurisdiction. Depending on how the interior wall is terminating into the exterior wall, we may have to look into different form of solutions. In order to provide you with a solution, we will need an EJ Request. Please submit your Engineering Judgement request on Hilti Construction Platform using the link below:
