Insulate my smoker. Ideas? I am wanting to insulate my smoker before winter start to rain and snow here in Michigan. I have a Smoke Hollow Pro series LP. (photo below). I was thinking of using a welding blanket but I am now thinking I will go with something more permanent. I just don’t know what that is. I was thinking of ¾” fiberglass panels with a ¼” plywood on the outside to help reduce damage to the fiberglass. I thought about leaving it in my garage during the winter but the condo association won’t let me put a chimney thru the roof. Some materials Ive looked at Fiberfrax Durablanket 2” thick – R-value unknown $145.00 to cover whole smoker (used for insulating boilers ect). Bonus is the scraps can be used as gasket material around the smoker doors and fire box. Polystyrene Insulated Sheet 1” thick R6.5(I worry about this melting) $24.00 to cover whole smoker THERMAX™ Sheathing 1”thick R6.5 (glass-fiber-reinforced polyisocyanurate foam core) price unknown called my local lumber yard and waiting for a relpy If anyone has some suggestions I would love to hear them.
