Is this better than the aluminum 157mil product?

Use peel and seal which is the butal aluminum kind, and its way cheaper! Then use this padded deadener on top of that !!

What is the width of the roll?

Thank you for your question. The width of Siless Liner is 16 inches.

Hi i am trying to Insulate my cargo van mercedes sprinter 2022 170 wb extended how many rolls do i need and will this work to control the temperature

You should be able to determine how many rolls you'd need by measuring the interior area you want to cover then comparing it to the roll size (which I believe is in the product description) As for temperature control I don't think this product is thick enough to have an impact on that.

what kit would be best to do whole inside of my 1964 VW bug?

Hi there! I suggest buy 36.5 sqft 4 mil enough for VW , Just working on 71 super beetle and cover door interiors ,cargo area( rearfirewall) and roof ! Have fun!
