Protection against wind and freezing cold...Still allows the smokers to breath. Both are slip overs with cut outs for therms or air.
Total cost. $23
Ok SUCCESS! It's 25* out with 8 wind chill and i ran the UDS up to 405* and taking it back down to 275 to cook some rib tips.
The silver smoker is snug as a bug in a rug...It wouldn't matter if it was sub zero outside!
1) It's called reflectix
2) Menards because they carried the 2 foot roll but Lowes and HD carry it as well. My lowes could have ordered the 2 foot roll but Menards has more sizes in stock.
3) Foil tape is what i joined it with
4) No not at all, the mini it did great. It still pulls the air easily from the top. The UDS i did the cut outs but probably could have gotten away with not.
