Have any of you guys used the heat/sound insulation under your carpets? I was just wondering what people are using. A lot of the stuff I see seems to be grossly over priced compared to some of the industrial stuff that I have seen. There might just be alternative stuff that will do the job just as well. Our console gets some hot in the summer and the air conditioning works pretty steady.
 
I've got it under the carpet in my C3 and it certainly helps. Still gets warm next to the console but it would just about cook you before. It's made by Hushmat.
 
I just came across a product called Boom mat. Probably the same as the others. $270 to do a whole interior. My problem is tire noise so I might be better off saving the $270 for a new set of tires when needed. If the car is still noisy, then go for the sound deadener. I'm just curious as to what people are using and their thoughts. Thanks Case.
 
for heat, the material that insulates the belly and side pans from the exhaust pipes on snowmobiles might be good. we used to buy it in sheets, but for the life of me i can't remember where.
 
There is a company in Canada called B-Quiet, I think there in BC. They have different kind of product and a lot of spec on their website including comparative specs whit Dynamat. You can call them, they will answer all your questions. If I remember right, it is cheaper than Dynamat. Post you result or project, I am interested to do the same on mine. I have already install the tunnel plate whit thermal ab from Elite engineering. It help keep the console cooler on short trip (less than 1 hr) but on a long trip it will get hot, more noticeable after exiting the highway, the 4 cats under gets very hot. Keeps the coffee warm but boil your water bottle. Stephane
 
I've also heard good things about Raammat. I think they have a kit that is pre-cut for Corvettes. Dynamat works well but it is pricey!
 
Keith, the tire noise in my car was driving me crazy too until I installed one of the rear partitions. After the install it was like night and day! I made one first out of styrofoam to see how it would work and it did, so I bit the bullet on the last free shipping from C.C. That big empty hole back there sure is a great amplifier.

I dare say that if you took the back seat out of any car, you would get a lot more road noise from that echo chamber. Everyone says that the Goodyear runflats are terribly noisy and I certainly agree. I was thinking of hitting on an industrial supply outlet like Acklands-Grainger to see what sort of stuff they have. The high priced stuff the Corvette dealers are pedaling is probably from industrial supply places. If all else fails Steamer, I'll follow your lead. I would like to hear the stereo when driving down the highway.

A quick search and what did I find? https://www.acklandsgrainger.com/AG...balProductDetailDisplay.do?item_code=PRFPF350

Because we do long road trips in the vette, I did the heat/sound insulating to my interior recently. I removed the seats, carpet, trim panels etc.
I ordered the insulating kit sold by Exotic Vette
::: Exotic Vette :::

I also applied A/C ducting insulation for heat/cold sold at Home Depot. This is 1/4" thick and is bubble wrap sandwiched between aluminum foil.
I used that for the console area along with the exotic stuff.
In the rear hatch area, and behind the seats, I used the Exotic insulation, and some Click flooring underlayment material that looks like the padding under automotive carpeting.
I'm not sure how this will help with heat/sound, but it has to be better.
Also, I'm removing the plastic liners from the rear wheel wells, and putting in a bag of insulation in that cavity.
It comes from the factory with insulation wrapped in black plastic, but it doesn't fill the whole cavity. I'm hoping by filling the cavity, this will also stop some of the rear wheel noise from entering or filtering through to the interior.

BTW, just by replacing the Goodyear F1 Supercar runflats with Firestone non runflats, it was night and day difference in road noise.

Hope this will help you a bit in what others may be doing or experimenting with.
:driving:

The loudest mufflers I have ever used were the Flo Pro Originals. A little louder than stock with zero drone. It's a shame they don't make a set for Corvettes. On the Chevelle, they were 14 years old and still solid as a rock. FLO~PRO - Original
Our car idles pretty quietly but takes on a mean sound from the engine compartment from about 2500 rpm on up......just the way I like it.
