Has anyone any experience wiuth the insulation kits you can purchase? I want to put it in to keep heat in, but mainily for the instalation of a sound sysytem. So if anyone has any thoughts or feedback it would be apprecieated.

Thanks

 

There is a product I saw on a TV auto show, "lizard skin" I believe. Not sure how it would work on the roof; but they use it for sound isulation etc.
