Sound deadening and heat shielding materials

Recommended Posts

I'd like to know what everyone that has removed the original materials off the floor and deck areas are using. I'm aware of several products:

Dynamat

LizardSkin (spray on)

SecondSkin

Hushmat

Ensolite

BXT II RAAMmat

Eastwood Thermo-coustic (poorly rated)

Noxudol 3101

B-Quiet

I'm sure there are many more. There are few things I'd like to know about your experience and knowledge of these products. Cost, performance, application issues, flammability are among the most important to me. Please slay me with your knowledge, recommendations and evaluations. ;)

We use Lizard Skin; great product. We got 5 quarts of both heat shield and sound; for $360 with the paint gun kit. Easy to apply and paintable. The only down side is that it will not stick to bare metal. I bought it from Tony Corriera of Barry White's Hot Rod Shop. Tony is a southern Cal distributor of Lizard Skin.

I used a product called Prodex from Insulation4less ( http://www.insulation4less.com/ ). It is a closed-cell polyethylene foam core with reflective aluminum foil coverings. it has a R16 rating and noise reduction of 19dB. Unlike bubble insulation, this stuff does not collapse under pressure or aging. Installation was pretty easy with 3M spray adhesive. I used about 60% of a 100' roll of 72" wide product.

I used megamat made by fatmat. Its butyl which is an adhesive rubber commonly found on butyl tape used in the HVAC industry. Advantages are that it has zero odor, sticks really well, has thermal insulation properties (no official R rating) and is affordable. Disadvantages are that its a bit heavy

I think there are plenty of good options on the market. The real key is to avoid anything made out of tar or roofing material like regular dynamat. Those products have issues with not sticking and terrible smell's when they get hot. Spray on material generally isnt thick enough to be effective in my opinion

Hi,

Anyone having had any experience/exposure with a product, 'Murdermat', please offer your comments.

From the company web site presentation, it appears to be a well thought out product both in its composition and application.

Thanks,

George

Murdermat looks like super Megamat. Its essentially the same thing with thicker butyl core and high quality aluminum. Im sure its great but its pretty expensive. When I measured the car i figured about 60 sqft to cover the entire vehicle interior. If you use a real firewall insulator and use strips in the doors you can probably make 40ft cover the car. Using strips on large panels is important because the goal is to reduce panel vibration and not blanket the vehicle. Using two 6"x12" strips on the inner rear quarter panels as well as two 4"x12" strips inside the door gave me that new car door closing sound instead of "clang/rattle/rattle"

Someone posted this link in another thread. Has anyone else tried this? Results?

That might have been me. I used it and am VERY happy. One - two gallon container is enough for an entire Z.

George, I just got my MurderMax the other day, the reviews are good and I thought the price was fantastic.

It will be a few months before I install it.
