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.

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.
