I guess you learn something every day! red65mustang, thank you for the information, to my misguided thinking I was under the impression that jute was a good thing-

APalusky, listen to DanTwoLakes-he knows more about Interiors than I will ever know-Dan, is rebonded Carpet padding available at Carpet Stores?

Yes, any carpet store has and uses rebonded foam carpet padding. I use 6 or 7 LB. and only 3/8" thick at the most.

BTW, jute padding would be fine if you live in an area that doesn't have big temperature changes. Also, if your car isn't going to be driven in the winter and you're not going to drag snow in and out of the car every day. It is extremely inexpensive and easy to work with, which are its best qualities.

The two pics are what I'm talking about. B-Quiet is just like dynamat or Raamatt and costs less.

my $.02
re-bond carpet under layment foam is "open cell" foam so it does hold moisture and dirt and odors,,,it is literally a sponge!!!

there are "closed cell" foams better suited so moisture can/will escape if ya just gotta have a more "cushy" floor...

save some bucks on the contact bond rubber acoustic insulation,,,,try a roll of "Peel and Seal" from Lowes/HD,,,
(none of them are great thermal insulators, they rely on the foil to reflect back radiant heat)

Rebonded carpet padding is made up of tiny pieces of foam that are all glued together and then compressed into their final thickness. Because it's all glued together and compressed, it does not act like a sponge. Here's a picture of water standing on the top of the rebonded foam carpet padding.

Closed cell foam does not "breathe" and will not let moisture "escape", it will trap the moisture between the carpet and the closed cell foam.

How many times do you get your carpet soaking wet, anyway? If you do, use a shop vac on it, get as much of the water vacuumed up as you can and let it dry.

Before I get you two guys flyin off the handle thanks for the information.
As far as peel and seal goes.. It is cheap, and it would work for awhile, but it would smell asphalt most of the time. It will also melt under high heat. The others including the Raamatt that I have now is a butyl. Not a asphalt material. No smell and stays bendable. I did my research on the different kinds. Dan.. Thanks. I will get the rebonded carpet pad. There is a carpet store in town that just leaves the last 4' on the rolls and throws them away.
I know with the Raamatt I have to put it on the floor, and in the doors. Do I also put it on the roof panel before the mylar covered bubbles?? Or just the bubbles, and then the headliner on the bows?? Al

Whatever you put on the roof will be an improvement if there was nothing there before. Just make sure you don't put too much up there to the point it interferes with the bows.

There is still some sort of matt there. It looks to be a little less than 1/4". There were two of them with a 6 to 8" gap between them. One is falling down while the other is still in place. I don't know if I should try to scrape the two of them off completly, or leave whatever is there up and cover it with either the bubbles, or Raamatt.. Al

I would take down the old and put in the new, whatever you decide to add.

I think you should be able to remove whatever it is with a wide bladed knife. Get as much off as you can so the contact adhesive has a good surface to hold onto.

APalusky,
you fell for some marketing "bling"????
if you had researched further you would have found that Peel and Seal is indeed Butyl rubber and has as little smell as any....
(there are asphalt "tapes" products that could smell and melt)
the aluminum foil layer on top stops odors period on any of them...
Hot Rodders have been using it for many many years with no failures or faults....
next visit to HD/Lowes smell a roll....

somehow, Dan and I constantly "cross swords", on wording a "technical interpetation" because of different back grounds...
as he said, and I agree, if you live in a low humidity/no rain climate and pamper the car even jute can be used...
(we always do sort out what the other is saying)

it's the glue on the surface used to bond the carpet foam pieces together that is making the surface water repellent....

it's "radiant heat" coming into a car,,, the aluminized bubbles will reflect it and stop it from getting soaked up in the carpet

LOL,,,
use some of both....

I'm thinking of using a coat of Rhino-Liner on the bare steel before putting down some underlayer and carpet. It should keep the heat and the sound down a bit more than just carpet and liner.

According to the manufacturer, Peel and Seal is a rubberized asphalt product. CLICK HERE Because asphalt melts at high temps and gets brittle in cold temps, the rubber is added to make it more heat resistant on the high end and more pliable on the low end.
There is a difference between it and the higher priced products for a reason. I'm not saying not to use it, I'm saying that you are not being "ripped off" if you decide to use some of the more expensive products. If something is thicker, has a better adhesive, or has more butyl content, it will cost more. You get what you pay for, and each car owner should decide on his own how much money to put into sound deadeners.
If you decide to use leather in your car instead of vinyl, or wool carpet instead of synthetic, it's a personal choice, just like what to use for sound deadening.

I bought the Raamatt, because I could get more product for less money. Dynamat Extreme wouldn't have been enough to do the floor all the way back and do the trunk, and the doors as well.. I guess because this will probably be my only car, and I have basicly built it by myself. Money gets rather tight. At our local Home Depot. They didn't have Peel and Seal execpt for the ice barier for roofs. I have a ton of that stuff, but is only about 1/16" thick, and does smell like asphalt. Now I have heard from a friend that has been helping me via the internet that I should double up on material on the firewall, under my feet and back to the riser for the rear seat. I guess that alot of heat builds up right there. Now would I use that carpet foam on both of these areas before putting down the carpet??, and do I have to use carpet that is designed for auto use??
