I had some yardage on hand for a while, and never had the time to do anything with it.
It's an interesting product. It definitely has limitations, just like any other insulation, it's not a miracle product like some people have hyped themselves up to believe, but I can see alot of uses for it.
I could put my hand under a layer or two of it and get hot nearly instantly, but if you compress it at all, it seems to loose it's insulation quick. It doesn't seem to be a complete vapor barrier either, but it's not the most breathable material in the world.
