Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

Nice sound deadening, self adhesive mats
Style: 18 Sqft 80 mil
These mats should work fine for my application. I’m applying it to the back sides of the hollow core doors on the closet where my HVAC is installed to reduce the “hum” from passing through. If I were sound deadening my automobile, I would probably use a heavier gage material. Overall, good product at a reasonable price.

Works well and doesn’t break the bank
Style: 36 Sqft 80 mil
Awesome value for low budget wound deadening. Used this under the floor mat on my international 4300 and there is a noticeable difference in sound inside the cab.
