Heat insulation
I need to find some heat insulation for my COE engine cover. I need to be able to glue it on the engine side and it can't be real thick....+or- 1/2 inch. And non flammable.
I plan to go to the junkyard and look at hood insulators, but not sure how that would work as the cover shape is very concave.
There are some insulation products available, but very expensive(as much as $65 a foot!). This is a low buck project, so I need some low buck ideas..
Thanks!

Several years back I bought a BMW hood from which I made some patch panels. It had a very nice insulation type blanket affixed to the under side of the hood. Try looking in high end passenger vans, mini vans.

Once you installed some of that couldnt you cover it with some light metal to keep it in place. Just like a hood.

With only a half-inch to work with, even a high-performance insulation material isn't going to do too much. A fibrous material with a stainless or aluminum sheet to reflect radiant heat is likely the most effective. You can dimple it to space it off the cover and have insulation behind it. (think cat converter heat shield)

What about coating it with Lizard Skin?

Not cheap at $90 a gallon either. Would be easiest to apply though. Hmmmm

If you want to try lizard skin for a lot less cost try this paint additive instead.
Insulating Paint Additive Makes Paint Insulate
I'm going to be adding it to some DIY bedliner and coat my cab inside and underneath with it. But you can add it to just about any kind of paint/coating.

But I'm also going to use a Heatshield Products Lava Shield in the area my header is going to be in.

It's not cheap, but it is cheaper then melting off my bedliner!
But Tinman52's engine cover shouldn't be as closse to the exhaust as mine will be.
But if he's worried I would apply some kind of paint with that ceramic additive. And then to keep things low buck find an old Econoline van in the scrapyard. Pull the dog house off one and remove the heat shield from the inside and use that.

Went to the junkyard today......looked at some hood insulators. Might work, but I see no easy way to attach. They are all pretty flat, too.
Then I looked at van engine covers. Seems most are a fiber glass mat covered with a thin aluminum sheet. I like this, but again, how to attach without drilling, etc. Plus they were all in pretty bad condition.
Also found some neat stuff at Aircraft spruce.......not real cheap either, but may have to bite the bullet.

I use peel&seal a lot for sound deadener, but was thinking the heat would melt the tar backing. Maybe I'll get out the heat gun and see what happens when it gets hot.....
