Headliner & Insulation

jbob0124 · Post by **jbob0124** » Sat May 29, 2010 9:10 am

I've pulled down my headliner to replace the fabric on it and was wondering does anyone ever insulate or lay dynamat down up top? I don't think alot of road noise makes it in through the there, but I know the heat does. Just curious on thoughts.

I am planning on putting some sort of mat on the roof panel of my SUV.

The size is rather large and I'm thinking maybe the added vibrations from such a large panel will be heard when the rest of the panels are deadened.
From reading some of the threads here. I am thinking a small patch in the middle of each larger section would do the trick.

I am not too worried about the sound from outside but more of the vibrations from the panels.

What auto are you working on?

If you can get some luxuryLinerPro or loaded mass foam like Tom just picked up it'll do wonders..... It'll even help keep the cabin cooler in the sumertime.....

Put a layer of dampener on there and a layer of closed cell foam on top that, that's all you need. I did and my roof is super quiet now, where before it sounded like a tin can when it rained.

The CCF blocks out higher frequency noises (wind, etc) which works really well up there.

You don't' need to put MLV up there b/c that blocks out more lower frequency noise which is pretty absent in the roof area. (Lower freq noises = think general road noise, noise from tires, etc etc.)

Im working on a '02 Dodge Dakota ext cab. It doesn't have a whole lot of open space, but there is maybe a 2 foot span of non-braced metal. Inside the cab isn't that loud as it is now. I may go ahead and do something such as the closed cell foam. Thanks for your inputs.

I'm working on a 98' Durango.

You might want to think about a medium size sqaure of heavy mat in the center to stop the metal flex and follow that with a full foam mat.
Might help with the fit.

Pics if you get a chance

Whatever I decide to do will be a while. The headliner has already been re-upholstered and put back up. Just trying to get idea's for when I actually do my install. I might even make a custom liner depending on how much space I use in the back seat.
