Self insulating my fire box

Postby Txdragon » Wed Oct 26, 2016 10:29 am

So I was bored one day and surfing the web and stumbled across some info that got me thinking; "Maybe I can insulate my fire box all by me lonesome." I searched a few options and came up with http://www.mcmaster.com/#standard-ceram ... n/=14rkihc
I am sure I can line the box with strips, kinda like laying floor boards but my question is this: How do I make them stick? How would I adhere these to my fire box?
I am thinking just lining the inside so it's gonna be a chore cleaning it up, but.. Any ideas?

Hmmm, interesting that the Adhesive Max Temp is only 300 F :?: Just my $0.02 but it might be better to use the same product without the adhesive backing and adhere it with a higher temp adhesive ???? :dont:

Yeah, I found the strips to use that are good up to 2,300 degrees but I need some stickum for it. I looked around and found some JB weld extreme heat, which is good to 2,400 deg. So with a little more search, I believe I answered my own question.. LOL!

Cool, sounds like you got it goin' yer way - - - the only thing I was concerned about was the adhesive backing being between the tile and your good JB stick'um :scratch:

I can hypothesize that the ONLY difference betreen the 2 sides is the self stickum backing and I can expose that side to the fire and apply the JB to the side that does not have it. The exposed sticky should burn off with ease after the first blaze is set.

Don't see how that'll work without covering the insulation with a layer of steel and fully welding all seems.

Why do you want to insulate your firebox? Properly insulating your firebox is going to make it much more efficient- meaning it'll run on a much smaller fire. If you don't have adequate room in your firebox it's going to make your cooker run a lot hotter. It may be a lot of work for some disappointing results.

So you are going to take a chance of exposing your meat to ceramic fibers that may brake down during the cook?
This is not a viable option in my opinion.

I would imagine with a heat rating of 2,300 degrees, I should be on the safe side of the fence against these failing like that. BUT, this is why I am putting them on the outside rather than interior. I had a brief time to give it more thinking brain power and said, "omg, was I REALLY plannning on these inside the box?!"

Methinks you answered that question yerself, Fin!

I anticipate I would use about 50% less wood to achieve and maintain my desired cooking temp. I believe if I keep my cook chamber uninsulated, I shall see no difference in variation (in the cook chamber) than I would without an insulated firebox.
