I've seen a number of different materials used for DIY projects to insulate the C5. My goal is to reduce heat and noise, particularly rattling.

I only want to do this project once, so I want to make sure I get a lot of good feedback to make the best decision.

Of the materials listed, such as Frost King, etc etc..

Can everyone please chime in and list what material in their opinion is the best, especially for noise insulation? And please list the pricing per sq feet or whatever metric is used to measure cost of this product.

Thanks in advance.

 

here is my web page detailing my experience and links to others.

in my specifics, weight and price were equally important to the amount of improvement. Your goals may differ. And if they do, then go to a more denser/heavier material.

there is a forum member selling a pre-cut kit of really good material.

and recently a newer supplier (Damplifier) is selling a fantastic product called Damplifier Pro - that has a 500 degree heat rating (but, it is kinda expensive). A forum member reported great results using it.

 

I used mike's method. it is great at reducing noise and heat. I found the duct insulation at lowes. go in with the information and have them look it up in the invetory. it will be with duct supplies not with insulation. price should be around $80.
note that you will need to adjust your rear compartment hold downs when you complete the job.

 

Thanks guys!

 

Mike, that is a great write up. In fact, I am considering this mod myself. Thank you for sharing the helpful tips, and, the informative "how to" pics.

 

Let me start by saying I am a long time reader 1st time poster.

I would HIGHLY recommend a product called B-Quiet Extreme. The site is here: http://www.bquiet.com/ They have pictures and plenty of information on it. I purchased 3 of the 70 sq. foot rolls for my 02 Superduty crew-cab Diesel. I wanted something that would kill the road noise and help the AC out (it gets hot in Houston in the Summer). I tried standard insulation, and it did not make enough of a difference.

My 5 yr old daughter and I put this in my truck over the course of 2 nights and the difference was UNREAL! She would peel the backing off and I would stick it in place. It is not thick and it easy to work with. The temp was around 38 or so and it was still easy to work with. All you need is a razor knife and a board to cut it on. You might also want to get a couple of flat tipped screw drivers. at around $70 a roll it is the best for the price (and better than dynamat regardless). They are in Canada. Check their site and look at the pics, someone did a Corvette and posted the pics.

This product does not smell or drip. It is thin enough for you to use 2 layers and your interior and carpet will go back in with no problem. I did the floor, A,B and C pillar, back wall and roof,and some inside the doors and I still have some left over. It makes a huge difference in the quality of sound from your stereo also. The result..My 7.3 diesel is as quiet as my 01 Lexus. Another product you might try is called fat mat.

I normally would not have said anything since I do not have a Corvette, however for a Corvette, only the best will do. 2 rolls should do just fine.

(6 more moths and the truck is paid for and I can get my Corvette!!!) Now I am off to fill in my profile.
