<VV> Sound deadening (Combined Posts)

Fri Jan 6 10:48:07 EST 2006

I went decidedly low tech and low cost.

The most effect sound deadening is the stock insulation over the engine. 
I found this out when I removed it... ;-)

Next most effective was rolling up cheap carpet insulation (from Home 
Depot) and stuffing it under the rear seat.

Next was using the same cheap carpet insulation under the carpeting (in 
addition to the factory-like padding that comes with some of the repro 
rugs).

In the rear fenderwells I used the 1" thick silver reflective insulation 
(like is available from JC Whitney though  bought it at a swap meet), 
making sure I also stuffed it up in the wheelwells. I used the same 
stuff on the interior of the car (covered with carpet) in place of the 
cardboard behind the rear seat.

Total cost was under $100 and it was like driving a different car!

I like Paul's "roofing felt" idea and will do that next time I have the 
door panels off....

>(Well, for those of us in northern climes doing this in the dead of

>877-727-8438.  Last time I ordered (about 1 1/2 years ago) it came in a
>70sq ft roll, with an installation roller for $134.99 + $25 for shipping
>via UPS Ground (it's heavy stuff). One roll did my LM sedan floor, front
>bulkhead, rear bulkhead and 4 doors plus the rear bulkhead and 1/2 the
>floor in my LM Stinger Clone, now in process. A 50 sq ft roll ($104.99 +
>$20 UPS) will probably do one complete car interior (except for the
>roof).  More than worth the cost and effort in reducing interior sound.
>Plus the doors now close with a satisfying "thunk".
