I was in my local HD today and noticed a product made by a company called Elastilon, it is a closed cell foam that is used as an underlay for hardwood floors, etc. I did the math (on a 107 sq ft roll after taxes) and its $2.26 / sq ft. Unfortunately I didn't have the extra $240 kicking around, but perhaps it would be worth splitting on with a friend!

Anyone seen or tried this stuff? It looked to be 1/4 inch thick

$2.62/ft^2 Lots of people on this forum use it and will testify on the quality (including my self) The seller is located in Alberta, canada (read: no duty/tax) I had it in less then week to my door.

He also sells smaller quantities so if 100ft^2 is to much, buy the 50ft^2. No need to go in with a friend.

 

go see these guys, if in TO by the airport...great prices. i just got some yesterday

100sq ft of 1lb MLV material, good for about transmission 35db loss, was $185.00
i got some stuff similar to Barymat M-100D 60db transmission loss. $160/27 sq ft

they have a bunch of different types to choose from with different size decouplers

 

what about this one.. in the past few weeks i was thinking of these CCF alternatives

^ It's a closed cell foam. looks good.

 

close cell foam for home or car is it the same thing?? or is there different densety and thickness?

 

There is different density and thickness to all foam products and both will affect performance. It is up to the consumer to decide their performance to dollar ratio

I think the one in the link a good choice due to the mold resistance, low offgassing, etc.

 

im gonna have to give this a wack. sometime this spring or summer..

 

Good read....I need to buy some of this stuff to improve the mediocre sound in my S2000.
