I have a commercial refrigerator that I took all the insides out, took all insulation out to bar metal, and want to put wood on the inside. I am wondering what type of wood would be good for the inside. I am thinking of using two types 1” each to save on money, the idea is to put one section down and the other on top and I will put a adjustable vent on top…I am going to use both electric/propane and probable wood to smoke with, at different times. Any and all info would be greatly appreciated. This is going to be used mainly for smoking mullet not sure if that make any differance as far as heat goes.
