    Has anyone put anything above a headliner? For sound deadening and insulation. I was looking at those dynamat type products you cut and stick or other suggestions.

    Po removed the headliner in a suburban, I got a new one and figured before I put it in, now was the time to do something if it's a good idea.

    I put 2 different types of Dynamat in my '90 Jimmy when I repaired my headliner. But I don't know if I could tell much of a difference because of the relatively small section that is metal vs the fiberglass top. I could tell a difference when tapping on the metal, but it is obviously covered by headliner, so it's difficult to tap on it anyway.
    I put Dynamat in the firewall, floor and back panel of my '70 K10 and was pleased with the results. So I honestly would recommend some insulation, and you may see a definite difference with the completely steel body of a suburban. But it will get expensive.

    I got some noico stuff from amazon that is way cheaper than dynomat. Using it to do the doors and floors of my mega cab with the new stereo but if it works half way decent I’m gonna use some on my Chevy too.

    Can’t say as to overall difference as it’s too cold to put it on, but it is def heavy and has gotten solid reviews.

    My brother used some of that aluminum bubble wrap insulation as a headliner in his Studebaker until he was able to get an interior make-over done on it..it actually looked pretty good,and did seem to cut down the noise and insulate good..

    I do understand the perspective on Dynamat being expensive, but sometimes it may be worth it. A direct comparison would be too much work and money for me to try. What I will suggest though, is to make sure that you find something that is asphalt based or whatever Dynamat is, and has great reviews as far as the adhesive. You don't want it falling down after a few years. Being inverted seems like it would be the most challenging for the adhesive to me. And buying enough for a suburban is something that you want to last.

    I agree with that. Mine are going on doors and floors so I’m not as worried about adhesivebut as heavy as this stuff I wouldn’t want it Fallin down.

    This suburban is all black to, which started my thought process.

    I can tell you that when I painted the fiberglass top on my '90 to silver from black, I lower the temperature about 25* on a sunny late summer day. I believe that it was 83* outside when I checked the difference between a still black top and my freshly painted silver one. The temp gun doesn't read the same on different colors, so I checked the inside.
    Apparently guys in southern areas have found out the similar results.

    I put some on the inside of my doors and on the back wall of the cab of mine. Just that made a huge difference. I just used some generic stuff I picked up from either Home Depot or Lowes. It's only 1/4" or so thick. But it was fairly cheap and one roll went pretty far. A second roll would probably finish off the whole cab.

    I started to use the half sheet of blue foam insulation I had left over from a home project. It was real bad in my old burb, no headliner at all. It fried my my noggin in the summer. Dark blue.
