Found out my 'fireproof' drywall only rated for 30 minutes after a neighbor's shed fire spread to my fence
I was checking the code on the leftover sheets from my basement reno and the stamp said Type X but the fine print was 30-minute rating max, not the 1-hour I assumed - has anyone else caught this kind of mislabel on big box store drywall?

Caught the same thing on a batch from a big orange store. Ended up going with 5/8" Type X from a proper supply house - the stamp was clear and it actually tested at 1 hour in a small burn we did. Had to rip out the old stuff and rehang it all, which sucked but beats losing the house. Check your local code office too, they'll confirm ratings for free if you bring a sample.

Is that really a common enough problem to worry about or is this just bad luck?
