TR engine cover insulation - redone!

Hello Gang. Like many of you out there, my car's engine cover insulation was deteriorating. I found some stuff on ebay that seemed to be what I wanted. It is cellular construction with foil on both sides, and about 4mm thick. So I bought a roll of 50 square feet for a measily $35. After ripping off the old insulation, I scraped and sanded the underside of the engine cover, then washed it and let it dry in the sun. Then I laid the new insulation onto the engine cover and carefully cut out spots for the mounting brackets. I then sprayed adhesive on both the engine cover and the insulation and squished them together. The insulation was formable to the corners and seemed to lay-out quite good. Well I won't make this a complicated story since this is an easy job. But here's a couple of pics.

That's funny. I did the same job yesterday! I got a roll of heat/insulation from a local car stereo shop. Paid $35 bucks also. Cosmic coincidence.

If its what I think it is, they sell the stuff at Menards. Its used as insulation on steel buildings, unheated basements, etc. You can get a huge roll (I think its what you have) for 30$ or so.

I was thinking of using the same stuff in my 914, as the original insulation is deteriorated.

Home depot has it too:

Any special adhesive? Did you physically remove the cover?

Yes I removed the engine cover to do the job. It was sort of a pain the butt to re-install the 3rd brake light and get it aligned properly. Other than that this is an easy job.

Insulation?

In looking at my 86 TR I don't see where there ever was insulation on my deck lid. Is that something the earlier TRs didn't have?

I noticed the picture of Brian's 87 TR and don't see any there either.

Just to update....I see several other sources have been mentioned for this insulation, but here is the problem. The TR engine cover is quite large and you need a roll that is wide enough to accomodate it. You certainly don't want to use a 16" wide roll of the stuff and have to splice it to get the proper width. So when I found the ebay stuff in the size that is needed, I jumped on it.

As for the adhesive, I used some 3M spray glue from our local Napa store.

The stuff from Menards/Home Depot is 48 inches wide...

bpu699 - Thank You for this clarification. I did check on some other links and saw only the "narrow" stuff. Based on your information, and the fact that I have now driven my car several hundred miles with no issues - All you Testarossa owners who need new insulation run out to Home Depot or Menards and get yourself a roll of this stuff. It works very well.
