What material have most people used under their carpet to quiet the road noise?
I see that the original jute material can be bought and installed but are there alternatives that may be better /and or cheaper ?

 

very happy with fatmat. dont even bother with the pre-cut "tarpaper" stuff the Olds part places sell, it's worthless

 

agree

 

x2 ^^^^ I've used fatty matty to cut vibrations down in trunks with bass =0 I used to install car audio out of my garage for a living.

 

Fatmat huh!! How about a website? Thanks!! O.... sorry for hijacking...

Thank you!

 

check ebay for the best prices.

 

what about the stuff from B Quiet ?

 

I did a thread a while back called "dynamat - worth it or a waste" that could help you.
Most of these similar products are okay, just avoid ones that use actual tar in them, unless you just love the smell! It melts in hot cars, too. This rules out most roofing stuff.
The dense heavy sticky stuff dampens vibrations and noise and the foamy stuff insulates from heat.

 

I've used dyna-mat in cars before and it works great, although it is kind of expensive, especially the type that is foiled on both sides. If you have a Lowe's or Home Depot (probably most places like that carry it), they carry a "foil both sides" material for use in houses that works just as well and is about half the price.

 

You could get away with using carpet padding in the door panels and behind the rear seat wall. This would be super low budget i need something anything will work type deal though. It wont be as effective as the real deal but should do some good.

 

I used Fatmat extreme and was about 1/2 price of the Dynomat on epay. I am very happy with the results.

 

Foil both sides ,yes i saw that stuff I have it on my inside garage door ,not bad ,insulates fairly well

 

That's Refexit, or something like that. Great for temp insulation, does nothing for sound.
But if you really want to go all out.

That looks like it should be nice and quiet
but with all those layers how does it affect
all your interior pcs going back in like the kick
panels and your door sill plates ?

 

it compresses enough to get all the panels back on, you may have to push a little harder than normal.

 

well it will be a while before I get to using one of these products as I need to replace some metal in the floor first ,got some cooling holes that shouldn't be there !
