hey guys,im new to this so bare with me.im going to build a new smoke house soon and want to run it by the folks on this site to see what yall think.the house will be 4x4x8 wood construction with a concrete floor" the outside im leaning toward cedar or cypress"with a metal roof with a 1.5 inch air gap around the whole top of the structure and a 6 foot door opening.i will use a fire box made of steel and burn either pecan or oak,the fire box is removable so i can build a fire outside the structure than move it in when im ready.do you think i should use some sort of insulation insde and than cover it with non galv metal for heat retention?i live in south louisiana and it gets pretty hot in the summer so im not sure if the insulation is needed.do you think i have enough ventalation or to much?any suggestion appreciated.thanks a lot ........duke
