sound deadening: sq footage amount for 3dr

[sqcomp]

Oooh! Nice little link. Personally I'll use Ensolite, it's more flexible and geared more for reducing resonances and adsorbing sound.

Here's something to look at:

"Polyethylene foam is a strong and resilient closed cell foam . Ideally suited as the material or part of a material required in products requiring a shock absorbing, this closed cell foam padding is also a great way to diminish the effects of vibration and dampening. Polyethylene is available as closed cell foam sheets that are well-suited for use as insulation, barrier or buoyancy component, and as a material for cushioning products in packaging applications. Polyethylene foam's excellent buoyancy allows it to be used in flotation equipment, and other nautical products."

"Ensolite, its durable, flexible and resilient closed cell foam with a medium feel. Its squishy characteristic makes it great for exercise mats, camping pads, boat cushions. Excellent for use in leisure, marine/flotation, industrial and automotive applications. "

I think we're looking at the difference between the poly being much more stiff of a foam versus the Ensolite being more of an absorbing material.

The foams that are used mostly in car audio applications for sound reduction are Second Skin Luxury Liner/Pro, Ensolite, Dynamat's Dynaliner and Extremeliner among others. The Ensolite you buy from Raamaudio is the least expensive.

I also realized that this foam would need to be treated with adhesive in order to be applied. But, do you mean that the Dynamat will make my doors heavy like a Lexus or the foam I linked to? The foam I linked to comes in different densities so it can get quite heavy in a hurry. And, just for the record, I want my doors heavy that close with a thud!

i'd say go with 1/2" and lay that foam over the top of a layer or two of mat.

That is a fair assessment. I'll go with that size and play it safe, especially since I can compensate lack of thickness with a higher density foam.

It seems their gymnast foams are similar to ensolite and they mention it in their description.

The problem I see now is applying an adhesive to the surface of this foam. I looked at Damplifier (which is generally the same thing, closed cell foam) and it's quite pricey, but does come with adhesive backing. Ah, decisions, decisions.
