What to put on ceiling above stove

Ok, so some here may know that I've been working on the stove room. It's being taken down to studs and redone. Hopefully, better than it was.
My question is that I've noticed the temps at the ceiling are quite high (I'll have to put he IR gun on it), so I'm wondering what might be a good material to put on the ceiling above the stove. The whole room gets pretty warm at the ceiling and is trapped there by a header leading to the living room.
The plan was to put up drywall, paint and be done, but I'm now considering something else like a pergo type material.
Need something that will withstand the heat.
Little help here.

 

Dave,- drywall, paint, and a Blaze King. No need to go nuts, this will work. What temps. do you think the ceiling area is actually getting up to?

 

I'll go hit it with the IR....brb.
ETA: Roughly 130.
But, the stove did one of it's "hey, I think I'll run away on Dave before he can stop me" tricks, so maybe it doesn't normally get quite that warm.
I'm doubting the term "airtight", although I know it is.

 

130 doesn't seem too bad at all. When you upgrade stoves, this will become a non-issue.
You want scary? Envision a Majestic open fireplace/stove, a crowd of cold women, and a large supply of dry Pine. Inside a house. With no supervision. I'll bet the flue temps. that night were....well, I don't like to think about it. But yet, here I am.

 

I bet it's lower than 130. I'd bet 110-115. I have low ceilings in the living room and when the Defiant is blasting, the ceiling has never been north of 120.

 

5/8 drywall for ceilings, pretty universal for " fire code"
Cover that if you want.

Stove pipe on mine has been red hot,
Was single wall then, but I walked away with the door cracked open
Fire took off before I got back to close the door.

 

I was thinking 5/8" too. Have to reset the ceiling support box snug up to whatever I do.
Almost like rebuilding the flue.

 

My ceiling over my stove is only about 36" above the top of the stove, since my stove is kind of in a bit of an alcove. I installed Durarock and tile on it, but I have never seen it get above 110, most of the time it's in the 90's with the stove backing. My side walls are another story, but the ceiling is not an issue at all.

 

if I remember correctly, it has to be over 300 degrees for concern.

 

Close to 4' from top of stove to ceiling. I'll shoot the ceiling again in a bit after the stove gets up to 500 or so. N/M, it's already past that. It needs to run for a bit to get a good reading.

 

5/8" is code

 

I've volunteered my brother......he just doesn't know yet.
