Keeping the heat in the smoker and not losing it to the outside can be a problem when colder weather hits us.

Insulating your regular or pellet smoker with a welding blanket might be an affordable solution and you can read my personal opinion at the bottom of this page.

Insulated Blankets For Pellet Smokers

Most pellet smoker brands offer special insulated covers for their pellet grills.

There are coming more and more after-market brands out and I found several of them on Amazon.

I have to be honest and mention that I think they are a little high in price.

However, the advantage of them is that they fit great and because of the maybe perform better.

Welding Blanket For Smokers – My opinion

Using any type of smoker in the wintertime means experiencing even more temperature fluctuations than in the summer months.

I have seen temperature drops of 40 degrees as soon as the sun went down on a cold winter day.

Although you can buy pellet insulation blankets for most brands they sometimes come with a pretty heavy price tag.

When I started digging more into the subject of keeping the temperature in any type of smoker as steady as possible I stumbled upon the use of welding blankets to do that.

I have welding gloves to protect my hands when I am cooking on my fire pit and also when I pick up my charcoal starter I never thought of using a welding blanket on a smoker.

It was not easy to find welding blankets that are a good match for a smoker. I found some great ones but they were so heavy that it would make it just harder to use on your smoker.

So, I had to find lighter ones that were still insulated enough to keep the temperature in the smoker from jumping up and down.

I do not try to bore you with many options and narrowed it down to what I think are affordable and usable welding blankets for most smokers.

Welding blankets can work with much higher temperatures than our smokers work on so although I mention the temperature they can withstand I don’t think that is much of a point to worry about.

If you have used a welding blanket as an insulation blanket on your grill let me know how that worked in the comments.

I have read about someone using a moving blanket on his smoker and that also worked according to him.
