I am considering getting a welding blanket for my IW885 to help with temperature control during the Chicagoland winter. There has to be an escape route the exhaust. For those smokers with a chimney, it is easy to cut a hole to fit over the chimney. Traeger does not make custom fitted blankets for the smoker models without chimneys because of the added complexity. It will take some creativity to wrap the grill without blocking the exhaust ports. I am considering using some big magnets to hold the welding blanket in place.
