Thermal cover for the 18.5"

Has anyone found a source for the Heat Shield Products thermal jacket for the 18.5?

I looked at a number of alternatives including a couple I've made with some of the recommended materials. My DIY efforts didn't handle the heat at hotter cooks so I'm back to exploring a commercial solution. I like the way the Heat Shield product fits but cannot find it to purchase.

That’s the one you reviewed, right Chris?
Yep, it’s pricey but, from the look you’d never need to replace it!

I think I have read about someone using a welding blanket as a blanket for their WSM.

I've used a fiberglass welding blanket and it does work, and handles the heat. It's just a bear to work with. I have also made a blanket for the pit barrel using an automotive firewall product rated to 300*F. It worked well for 225* cooks. But cooking at higher temperatures caused the inner insulation material to begin to melt.

I modified my blanket by adding three layers of the fiberglass blanket material to the inside of my DIY blanket. This added margin to the upper temp limit but it also begin to melt after a long cook above 325*. I'm considering trying one more time by removing the automotive blanket and constructing around the fiber glass material only. This is a challenging task since the fiber glass material is challenging to work with. If I find success I'll report back.

Yes, that's the one I reviewed in my video. The maker thinks this product gives the WSM the efficiency of a ceramic cooker at lower total cost, i.e. $329 WSM + $239.90 cover is less than $859 BGE large.

The thing with cheap fiberglass welding blankets is that they shed particles when handled.
I worked with them and always itched after handling. You lay it over something in direct sunlight and you can just see the fiberglass particles floating thru the air.
Not something you want to drape over a smoker when it can affect the food IMO.
