1969 Roadster Carpet with Sound and Heat Insulation

[Steve P.]

About to start the install for new carpet in a 69 Roadster. ( First time for me ) I've heard sound insulation is worth the effort. I have found several suppliers. Any recommendations on the insulation or tips for a good carpet install. I ordered the Al Knoch carpet with the jute attached. Thanks....

Steve, I have not tried this on a C3, but on my 99 Corvette, I used HVAC duct insulation that you can buy at Home Depot/Lowes, etc. It comes in a roll and has adhesive on it. I was very pleased with the results of using it on my C5.

Hi Steve, I sent you a PM regarding your carpet. Can you let me know if you received it?

Thanks

Although the interior of my '70 wasn't particularly quiet, noise level wasn't an issue with me. But it had a serious radiant heat problem. Heat transmitted through the floor and tunnel made the interior extremely uncomfortable.

While replacing carpet, I lined the floors and tunnel with Dynamat and Dynaliner. They're designed to work together, as a noise and heat barrier, respectively. This solved the heat problem, and as a bonus interior noise is much less too.

Be aware that the extra thickness of these barriers will be noticed in judging. So decide what's important to you.

While doing this, it's important to also seek out and plug any and all holes, gaps, torn boots, missing/loose grommets that allow hot air and sound to enter the cabin. With the floorpan bare and in a darkened garage, shine a bright work light from underneath the car toward the floorpan. Then carefully look for any signs of light from inside the car. You'll be surprised what you see.
