I am in the process of building a smoker out of an aluminum traffic signal box and i would like to insulate it. I have read about using Hardie board as an insulator but I'm not sure how to install it. Is there an adhesive that is safe to use?
How critical is it to sheet over the rockwool? I've been thinking about insulating my Chargriller for a while, but I don't know what would be the best material. This sounds like it could be a really good solution.Hardie board is a cement product that absorbs moisture... Thermal mass is high... and it takes forever to heat up... I have it in one of my smokers and it is a PITA.... takes forever to warm up and release all of its moisture.... I would suggest rock wool.... fire proof and light weight... put it on the outside and sheet over it with something attractive...
Of course, you could try the smoker without insulation.... living in Fla, insulation is not an absolute necessity....
You could use the same material that insulators use to sheet over piping in commercial applications.. Rockwool comes in a "water resistant" form also.... I would us a 26-28 gauge metal wrap over it... Prepainted, baked on finish would be one choice....How critical is it to sheet over the rockwool?
