Sup guys what is a low cost alternative to keep the heat out of my interior and deadn interior noise, something i can line my doors with and under my carpet ,Any ideas and pics!!!

 

Dynamat material, do a search on ebay, they sell the stuff by the roll. I have one I was going to use but never did. I may get around to it someday.

 

Hmmm.... I know you said a low cost alternative but I wanted to chime in with what I did and was quite pleased with the results...

Here's my thread on my sound deadening project... be sure to check out the second installment thread below as it has the most pictures...

As for keeping out interior heat, in addition to the sound deadrning material over the center area, I highly recommend a tunnel plate which made a tremendous difference.

 

I just did mine last weekend. I buy Fatmat, 50 feet at a time off ebay. I'm on my second roll. It worked outstanding in my car. I did every surface I could touch without removing the seats or carpet. I even covered around the auto shifter plastic and did the bottom of the center console. Heat problem solved under the arm rest. I have pictures, but have no clue how to add them to this post! I covered my doors including the plastic coverings and did inside the doors as well.

 

That is a good product. Check out Madvette Motorsports for a kit for the C5 - forum member Patches used it on his wife's car - not sure if it is a heat insulator, but it did a good job on the sound.

 

Yes it does, the black adhesive part is for sound dampening and the aluminum layer is to shield out unwanted heat and cold.

 

Thanks. Great detail write up. Your link for Phase I/Wheel Wells is not working. Do you have the thread title?

 

I used the Madvette kit on mine, amazing improvement in heat rejection, took away all the road noise... etc...

 

For just heat, you could use something like Frost King. It works very well at blocking heat transmission. I think most of it comes from the center tunnel. It will also block a small amount of sound over 6Khz or so.

Luxury Liner will do an OK job of blocking heat, and will block sound better than anything short of lead. But it's thick, heavy, and expensive.

Dynamat will block a little heat. It's really designed for viscoelastic damping. It's not designed to block noise.

Imagine a tuning fork. You hit it against something and it goes Diiiinininininininining. Dynamat is designed to stop that action.

Although Corvettes are plastic tuning forks, aren't they?


Be careful of people exaggerating the effects of different materials. Even the $4/1lb a square foot heavy material only dents noise. Anything less has no real effect on low frequency noise. *

If you wanted to block low frequency noise with foam, it would need to be a foot thick.



* Automotive engineers know this. If you have gone into the noisy areas of cars you will notice a vinyl layer with foam underneath. This is the same basic concept as Luxury Liner, except LL is considerably more dense.

If you do insist on buying a dynamat like material - STAY AWAY FROM ASPHALT -

There are three quality mats I would be willing to use. I won't touch anything else.

Second Skin Damplifier Pro - Highest quality, expensive.
Dyanamat Extreme - High quality, very expensive.
Raamat - Very good quality, very reasonably priced (And a forum vendor)


I use mostly Raamat and also some Damplifier Pro that I won in a contest.

 

Get a tunnel plate off ebay for $145 plus shipping. They are even ceramic coated.

 

Think I'll make my own tunnel plate I'll post up!!!

 

Get one from Elite Engineering. Great fit and finish and a little added stiffness to the body. Good guys to deal with too.

 

Thanks guys!

 

How hard are these to install?

 

Looks like all u have to do is drop your h pipe or x pipe an unbolt it and reinstall new one simple,easy pleasy lemon squeezy!!!

Ill take mine off an trace it onto a piece of 3/8 SS and drill out the bolt holes my buddy has a full shop up the street Im sure he'll give me some stock layg around and save me some cash!!

 

Pretty much sums it up.

 

Get a ceramic coated tunnel plate from Elite Engineering. This will solve your problem very fast.

 

way too expensive for what it is. go to a local lowe's and buy reflectix. it is like dynamat in application. it is two foil layers around bubble type center. very easy to use and work with. very cost effective. it is used in a/c applications (duct liners/insulation etc). did my entire 78 pacecar and it must have reduced the interior temps a whole bunch.

 

It is really helpful to have a lift. Taking out and turning in 36 bolts tires even the strongest arm/hand, Spray up the exhaust bolts the night before.

 

I installed the Madvette kit over Christmas vacation. It's a pretty good effort to disassemble all the interior and add all the insulation, but it does help reduce noise and heat. 6 months later it's hard to even remember what a pain it was...plus as a bonus you are liable to find some extra pocket change.
