That stuff sounds amazing, R-24 with 15 mil thickness! Maybe I should take off the inner skin and coat the inside of the outer skin? Seems like it would make it nice and cozy.

Kind of expensive, I guess.

I wouldn't get to excited about that R-24 number. Has to be "modified" test. Still I'll use it between the sheets in combination with the reflective foil with a foam cord.

I've used 3M Super 77 spray adhesive in the past, but it's no good if you need resistance to high temperatures. It will soften and melt, leaving a gooey mess on everything it touches. This is especially true if you're gluing headliner material or convertible tops - ask me how I know!

The trick is to use a true contact cement, whether aerosol or liquid. J. C. Whitney offered a special spray adhesive for use with its soundproofing material, and it has proven very satisfactory. It stuck firmly and quickly to the underside of my doghouse and hasn't shown any signs of loosening over about 1-1/2 years.

I would reconsider not thermally insulating the floor. The fan or airflow thru the radiator blows heat everywhere and you are sitting right over it.

I used some rubber underlayment left over from a flooring project to insulate around my dog house. Seems to make a nice difference in the sound level. I intend to double it and lay it under the front carpet. I also found a source for a stick on padding that could go up inside the firewall area...very reasonable. I bought a sample..it looks like it would do a great job. Check it out here---

Uh-oh. I wouldn't try anything used by Boeing.

They need to re-insulate 1600 aircraft because of an insulation 'fire hazard'.

Arrow Hush Mat

I recently read an Article featuring an audio system upgrade in an Ford E-350 van that also used a sound-damping product called Hush Mat. Hush Mat is a pliable material that will adhere to the multiple contoured surfaces with our surface preparation or heat, and it can be easily cut to shape. It is designed to create a barrier that eliminates vehicle squeaks, rattles, engine growl, and road noise. Check out their website: www.hushmat.com

serious db reduction

I just called the local (Marietta) distributor, for a bulk pack: 399. +tax

Thirty (30) 12.1" x 23" Sheets available in either black or silver. 58.7 square feet (17.9 square meters). A Bulk Kit is enough to treat an entire mid-size or smaller vehicle. Utilize a Bulk Kit to supplement the other kits above. Or simply purchase a Bulk Kit and apply as needed.

In my opinion I would go with the b-quiet product because of price. All the products, b-quiet dynamat hushmat, are pretty much the same thing. They are all a black tar type product with a metallic backing. The only difference is price, b-quiet cost about half what the others cost. I bought it and it is very easy to cut and apply, make sure you get the roller or a roller, helps a whole lot when installing.

I wonder how much that would weigh, could be pretty heavy even in a motor home.

Now that I am driving with a 2005 engine which is whisper quiet at almost any speed I find that all my noise comes from the road. I need to find a way to sound proof the firewall in front of the driver's and passenger's feet. The silver stuff used by Airstream is useless, then there is all the glass and I wonder what is in the headliner besides plain old insulation.
I reall should not be complaining since my wife and I can carry on a conversation at normal voice while doing 60 on the interstate. However, there is still room for improvement.
