We have a fire barrier, with a fire-resistance rating of 1-hour, that has conduit passing through.
The conduit is not continuous from device to device, only used as a sleeve for the penetration.
How long (continuous) does the conduit need to be past the edge of the fire barrier to maintain a 1-hour rating?
My concern (however minor) is that the inside of the conduit is not firestopped, only the outside penetration. Smoke could pass through the inside of the conduit and effectively circumvent the fire barrier.
Thanks in advance, big fan of the forum.
