Sound Dampening Material

[Matt34]

Anyone know about a good but cheap sound dampening material. What was in the car was a rubber like material and maybe 1/4 to 3/8 thick maybe but it is all cracked and torn in spots.

A lot of what I see online they say is 80mm thick which is like3 inches and some change. Know I probably need to replace it before putting in a new carpet kit but not sure what to buy.

I still have the old ones that were there and could use them as a pattern for new ones so don't have to buy them pre-cut.

Any suggestions???

Sound deadening has gone up in price so be prepared....

I would use one of the Dynamat brand knick offs. Cover the entire floor and then jute and then carpet on top of that.

I just did this set up in my Ranch Wagon except I used vinyl floor covering instead of carpeting and the car is remarkably quiet for an old car. I was very pleased with the outcome.

Same here. I bought a couple rolls from summit.

I used Dynamat Xtreme, bought a couple of bulk packs of Amazon.

Cheaper stuff will be FatMat, HushMat and B-quiet.

Yes and the stuff I guess they use to use, or at least what came out of my car, looks a lot like a thick piece of tar paper you would put on a roof under shingles.

[ctrlraven]

Yeah people still go that super cheap route and the stuff stinks to holy heck.

Dynamat is rated the highest in quality but that also comes with a price due to the composition of the material it's made with. Differences between it's competitors is the millimeter thickness of the material and proprietary formula of the material. I'm sure stuff has changed since the days when I used to do SQ and SPL competitions.

Also have to remember that the thickness that is claimed is when it's in sheet/roll form, once you get a roller on it and start working it in then it becomes thinner.

Remember though guys we are dealing with a 1963 vehicle which has not undergone a rotisserie restoration so I am willing to bet the investment in the top if the line sound deadening material will not pay off.

The stuff I use us is around $3 a sq. ft. and I am will to bet it stands up to the higher priced stuff when used in an application like Matt's.

What is the brand that you use Marty

Is there a spray in application that would get in all the little nooks and crannies?

I'm by no means saying to only choose Dynamat, there are a bunch of options, Dynamat, HustMat, FatMat, B-Quiet, DeathMat, SecondSkinAudio, Thermo-Tac, Stinger RoadKill, NVX and a few more I am probably forgetting.

Just as you are speaking of your experience, I am speaking of mine.

This would be the cheapest route

Anything is better than what's not there currently. Just make sure whatever surface you will be applying stuff to has been cleaned with denature alcohol and lay the product out on a flat surface in direct sunlight for a few hours before using it, the sun will heat it up and make it more pliable.

The smelly stuff is really mostly roofing tar paper from HD/Lowes. 3M makes an aerosol rubberized undercoating spray that can be used for tight spots but really isn't needed as any material can be cut to whatever size/shape you need. Make sure adhesive is Butyl type and find out heat tolerance of the product.

I know sometimes the glue material can freeze and becomes brittle or pops of what it's supposed to stick to. I have a headliner to prove it.:depress:

What does everyone here think about putting the jute that was in the car back in the car after cleaning it well with a degreaser and maybe some bleach solution???

The more I look at it the more it really does look as though it could be re-used. It's about 1/8 thick and has some tears but after being glued down well that wouldn't matter much I don't think plus its already molded. And a super plus is it would save matt some money!!!

Then putting down some jute padding 40 (1/2 inch thick) and then the carpet kit which comes with more jute padding already on it.

Bad Idea???

[martyo]

Have you priced jute? It's cheap. Get fresh stuff. The old stuff is contaminated with dust and odors. I know this and I have not even seen it.

[jwibbity]

Knukonceptz is my choice

[Joe Walsh]

My brother and I lined the aluminum floor pan of the Cobra with Dynamat.
It is heavy and expensive stuff....but it works great!

The Cobra is dead quiet on the road and over bumps.....:hmmm: .... well except for those pesky 4 inch side pipes!....:eek:

[Matt34]

I have not priced jute and by jute I mean the layered tar paper looking stuff under the jute padding. It may not even be called jute but that's what I was told.

All the jute padding (stuff that kind of looks like carpet padding) I am gonna replace, already bought it actually. Not sure where to look for it honestly Marty, I haven't seen any on ebay or rockauto or Dearborn or anywhere else.

Was thinking of buying something maybe from like Grainger but their padding material that is similar to that is expensive.

Where would I look to find this stuff by the yard?

Jute is the carpet padding stuff.

Can you post pic of what you are talking about?

[Matt34]

Here it is in the front. It's about 1/8 of an inch thick and I think its original but cant really be sure

[martyo]

Replace with the Dynamat or other brand materials we talked about. Then cover with jute and carpet and don't look back.

[Matt34]

ok, will do
