Quality product
Really happy how my van turned out with this 3m insulation. It arrived in just 2 days and came in two 10-foot sections, which made it very easy to handle and move around my garage. I measured it myself after it decompressed and each roll was actually 10'1", so you're getting a little more than expected. Good quality material and well packaged.

Great product and way easier and cleaner to use than wool.
Better Thinsulate than I was getting from online van conversion outlets. Worked perfectly and great packaging and quick shipping.

Not 10’
9’6” rolls NOT 10’. I tried to stretch it as much as possible (I need 10’ runs) to see if it just shrank in packaging. Nope. If I didn’t need this ASAP I would definitely return.
