This is in the garage of a new home, It is a crawlspace access. Is it a breach of firewall?
If I understand your post correctly… YES, it is.
Yes. I call out crawl hatches that are not fire rated in the garage. All surfaces adjacent to the living area need to be fire rated.
i thought so
Just to play devil’s advocate…
How thick was the subfloor and if it is 1 3/8 inches, would it be any different than the fire door of the same thickness?
Looks thinner
I agree Bob. It only looks like 3/4 inch but it was just for discussion.
So, now do you have the answer to your first question? Just curious the answer.
