Membrane Penetration detail - recessed box within CMU Wall
Hi -
I am looking for a UL listed or similar rated detail for a large 30" square x 6" deep recessed box within an 8" CMU wall. In this situation the entire cell depth is used and the remaining membrane is the original face / wall only on one side.

Hello - thanks for using the AskHilti platform.
This condition will not have a listed system but instead will require an Engineering Judgment. You can request an EJ on the Hilti Construction Platform which can be reached here: https://www.hilti.com/content/hilti/W1/US/en/business/business/engineering/fire-protection/engineering-judgments.html
