I have a product called Foiltec (?? sp) in my 40x80 shop.. Its a bubble wrap product with Mylar skin on both sides.. They say the Mylar reflex's infrared heat back into the working area.. Then the other side keeps the summer heat out.
Stuff is unreal. Came with a seam tape that has stuck now for around 14 years and not one has come loose..
I have toyed with the idea the day I do a inside remodel to use it on our 72 Overlander to use this type.. I think about any high grade contact glue would do a fine job to hold it all in place.. More research needed before I could say yes or no..
As far as its inslation,, and sound deading I must say it has to be over the top for as simple as it is.. Not the cheapest,, but sure worked in my steel building..
