Yes...and there’s more to the story than just compatibility of the materials. The plans almost never identify fireblock material. I always ask the architect to be specific. Quite often that takes a while. I don't know why a contractor would simply go to Home Depot and look for the least expensive fireblock and call it good. Sometimes they ask what I will accept. I reply that the one specified on the plans is okay with me.Good reinforcement to always double check the acceptable materials on the fire stopping design.
I was curious about that as well. The first time that I encountered plastic sprinkler pipe I thought it was a typo. But no....it’s legit....melts in a fire but costs a lot less....as it should.I'm curious, is CPVC allowed in a building of this size? Wikipedia says it has 19 floors.
