Not what I was thinking. I've used insulation like this that was composed of heavy material, this one is not. This product must be for boats or airplanes where weight is a primary consideration and noise is not a problem. This is too light to have an effect on vibration or road noise. Absolutely zero difference. Anyways, I have both front doors full of the stuff and I'd pass if I were you.

Great in my trunk

Was almost enough to do my full trunk on my 2012 civic si. I have exhaust and a subwoofer that were making a lot of rattles and drones in the trunk. Took everything out and covered about 70% of everything including the wheel wells and the rear deck support, even put some under my spoiler and behind my license plate. Now, quieter ride and no vibration from the trunk inside OR outside the car even with bass cranked up. This is a great product and I would definitely recommend.

Does the job well

Style: 37.1 sqft（34 pcs）, Material Type: Aluminum 197 mil

Really nice quality. There are strings woven into the top along the foil. Easy to work with. The backing peels off smooth and usually in one piece. Great value

Worked out great. Good stuff and sound deadens the vehicle without adding a ton of weight.
