I am in the process of converting an old Fridge into a smoker. This fridge originally had the foam insulation and after many hours of frustration and beer, I finally have it all out.
Now I am stuck; being in Guam, getting materials is a challenge. I have searched the forums and have found many ideas of new insulation material.
Rock Wool seems to be the recommended material for insulation but I can not get this material on island without paying ridiculous shipping fees. We have a Home Depot on island, but it is more like a "Home Depot Lite" We are very limited in materials. I have read that cement board can be used, but reading the manufactures technical date, it says you should not expose the material to temperatures greater than 220F. I have thought about using a wood insulator, covered in 1/16" sheet metal, but the obvious concern of a fire comes into my mind.
Basically the materials that I have available are cement board (1/4" and 1/2"), standard drywall, or plywood. The cement board is what i am leaning towards, as I have read in this forum that it can be used. Should I be worried about the fiber mesh breaking down and causing fumes? Should I put two layers on each wall (total 1" thick)? Should I just throw this shell of a fridge in the Talofofo River and call it a day (hahhahaha)?
Also, what is the standard method of attaching the cement board to the walls of the fridge? I was going to go with glue, but if there is a better way, I am all ears.
Thanks for your help. I have lurched as much as I could in this forum, I had to ask. I am sure this question has been asked many times, and I appreciate all the experts help.
This is going to be a charcoal smoker, used for everything from Pizza, fish, pork shoulders, and ribs.
