## Questions & Answers

**Q: Is this better than the aluminum 157mil product?**
A: Use peel and seal which is the butal aluminum kind,  and its way cheaper! Then use this padded deadener on top of that !!

**Q: What is the width of the roll?**
A: Thank you for your question.

The width of Siless Liner is 16 inches.

**Q: 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**
A: 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.

**Q: what kit would be best to do whole inside of my 1964 VW bug?**
A: 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!
