Is the "super heating" caused by an evil maxi mirror designed to relect heat into the drywall? Asking for a friend because nobody is sure how fire became the topic. We will need Fire Marshall Bill to tell us about fire....but my garage is still 72 degrees, fire free, with special fat man ladder made of aluminum. Just putting this out there...fire rated drywall is 5/8" and I doubt there is any fire rated drywall in my house or yours....you don't see sprinklers in the builds, do you?

You are correct, fire rated sheetrock is 5/8". The building code here states 1/2" gives you a 20 minute rating and that's only used if there is no living space above the area in discussion. For us here in the Villages, usually the attic space above the garage is open to the rest of the attic over the living area. If a fire breaks out in the garage, when it penetrates the ceiling it quickly spreads to the rest of the home. But as you mentioned, this is not the topic of this thread.
