One sided fire stopping

Posted by Joey Beyerabout 7 years ago
One sided fire stopping

I have some corridors that run into the main area of my building. These corridors are 1 hour rated and have multiple cable and conduit penetrations. The way the construction sequence was has made it nearly impossible to get up to firecualk both sides of the wall. Is there a system where I can just caulk or stuff from one side of the wall?

Hello Joey,

We have multiple one side solution firestop systems.  Please see attached systems for metallic pipe and cable penetrations through gypsum and concrete/block walls.

Regards,
Cody

Hi Andrew, Yes we have systems for this. Please see systems WL 1205 and WL 1206 on this thread. The sketch shows shaft wall but it allows for it to be a regular gypsum wall in the notes section. You will need to install a sleeve to be able to install from one side. Regards, Cody

Hi Cody! Hope you're still with Hilti and get this message. I am looking for a 2 hour one sided application for 3-4" conduit penetrations through a 2 hour assembly (non shaft wall). Got anything that fits this description??
