I insulated my WSM with foil backed insulation. It looks like a space ship now but boy it really holds the heat. The challenge now is to keep the temp low enough without choking it off. I runs with just one vent BARELY cracked. Anyway, it ran for 15 hrs. the other day and when I took the butt out I shut the top vent. Next day I checked to see how much charcoal was left and was amazed that there was over 1/3 left. Awesome. I should have put a chunk of apple in though. I didn't because I like the brisket with no additional wood. I am running Royal Oak lump and it seems good as it is. Maybe just a smaller piece of wood. I used the leftover charcoal this morning to smoke some jalapenos it is running great, as usual.

Maybe put some silver painted styrofoam balls connected to tin-foil wrapped dowels on top.... would look like antenna on a silvery marshan

No. It's fiberglass. I then took the Red Green route and used duct tape to secure it. That will react to some heat but it might surprise you. 

I just did the middle and top sections. The middle section has a cut-out for the door. When I say cut-out, it still has a flap of insulation over it.

It is not so pretty that I want to send pictures.

Originally I thought about using that spray foam around it but I couldn't come up with a form and the door would have been even more of a challenge. It might have looked like R2D2 with a serious fungus infection then!

I guess the point was that it works good and that you may want to try it. If not, OK.
 
did the insulation show any damage from heat?

 Why not use sheet metal tape, it's what we use in hvac, and it will withstand a lot more heat than duct tape...
