How many of you have added insulation to your car?

I thought that I had read discussions here. Do I want sound or heat insulation.


I have seen a number of posts in different places about how much quieter [sound] insulation can make a car and how much they enjoy it. When I took my Accord to different body shops one suggested dropping the headliner and pushing out the dents.

Presumably with a mallet. I think that I prefer the headliner when I use my fist, but I still would not recommend that.

I watched a video and it looked like I could drop the head liner in about five minutes and it looks pretty simple to install sound deadener on the ceiling. Here is the stuff that Shouty recommends:

Thirty-six square feet for $66 and I can finally cut down on all of that road noise at 55 MPH!

So, have any of you insulated cars? Do you prefer thermal insulation?
