How quiet is it?Justin wrote:I used dynomat. They have complete car kits for like $400 or so. I did the doors, floor, rear panel, pillars and some of the firewall (what i could reach). It works well but people consider it expensive..It is mostly used in the audio industry..
I have also used Dynamat, but not the new "aluminum xtreme", just the plain black sound deadener.Justin wrote:I used dynomat. They have complete car kits for like $400...
I was just at Lowes the foil bubble pack is cheap enough but I'm not sure of its sound deadening ability.

It is pricey, at close to double the price of the "Brown Bread" linked above, and I had a problem of it losing adhesion after about a year.
Pieces fell loose in the doors, and came loose on the rear wheel tubs.
Hopefully the newer adhesives are better than that.
Personally, I'll just be using the bubble pack for my needs. I have used it on firewalls , under carpet , headliners and under door panels.
Maybe the thing to do would just use a few squares of the "Brown Bread" inside the doors for deadening and bubble pack the rest?
Has anyone had our doors apart? GM was pretty good about adding some sound deadening in the doors, I wonder if there isn't already some in there?
The foil bubble sheet is primarily a radiant heat barrier. It does deaden the sound some, but does not adhere to the metal to reduce the transfer of sound.Jim wrote:...I was just at Lowes the foil bubble pack is cheap enough but I'm not sure of its sound deadening ability.

I may just have to bite the bullet & go for the bread.

I ordered 2 sheets of the Sound Deadening & one 40sq ft roll of the insultek. My concern with Brown Bread is how well it sticks. If you cover the inside of the door, then need to repair something it could ba a pain. The foil faced Insultek would only need to be adhered behind the door panel at a few spots. If I like the stuff & need more I can pick it up the end of Sept at the fall Carlisle swap meet.HenryJ wrote:I didn't have any luck with the drop down menus using Netscape so here are links-
Sound deadening $2.32 per sq. ft.
Insul-tek foil $1.13 per sq. ft.
Carpet underlay $0.50 per sq. ft.
Use all three and it will sound like a Caddy inside $3.95 per sq. ft.
Check your local lumber yard (Lowe's, Home Depot, etc.) for the foil bubble insulation. I'd bet it will be cheaper than the sunshades.a2b wrote:...i am about to put a new head board in my truck. so i just get the same bubble foil peice that i put across my winsheild and just get 2 of those and cut them to fit in the roof?
Peel-n-Seal, hmmm...Conclusions
As I have stated repeatedly, this isn't a rigorously scientific review. I got a bunch of samples and did what I could to evaluate them. While this approach is obvious lacking in a lot of ways, I think I learned some essential truths that should help in your evaluation. Additionally, since I posted the first version of this project, I have been contacted by some legitimate experts in this field, several of whom contributed important context and guidance.
Ideally, I would have loved to actually measure the effectiveness of the samples I had. How well do they dampen?. How effective are they as a barrier? These would be great things to know.
I think I have gotten to the bottom of the product failure problem. In the asphalt versus butyl debate, I am convinced that butyl based products are better in every aspect. So what do I recommend?
I would have no qualms about using SecondSkin Damplifier or Damplifier Pro, Dynamat Xtreme, RAAMmat BXT or B-Quiet Ultimate. That said, two product lines stand out - one of these will meet your requirements.
Highest Quality
Second Skin's products live up to their "Over Engineered to Over Perform" motto. They are clearly a higher quality alternative to Dynamat Xtreme - designed for greater heat tolerance, with higher quality materials.
If quality is your most important requirement, Second Skin Damplifier or Damplifier Pro are the obvious choices. Dynamat Xtreme is close, but being more expensive and not as good isn't a winning combination. I congradulate Second Skin Audio for their obvious dedication to providing the best product possible.
Best Value
RAAMaudio's RAAMmat BXT is a high quality product priced to compete with asphalt mats. If you are considering an asphalt sound deadener based on price, please reconsider.
Remember, you are not just buying square feet, you are buying mass. Most of the asphalt mats are thinner and the lighter than the butyl products. This means you will need more layers to accomplish the same result. The only close comparison is eDead v1SE vs. RAAMmat. They are close in weight and thickness, despite the fact that Elemental Designs significantly overstates the density of their products.
If I were to repeat my own installation - 300 square feet of damping mat - here's how it would price out for RAAMmat BXT and eDead v1SE, shipped:
RAAMmat BXT $594.00
eDead v1SE $513.00
There is only $81.00 between the two. If you use less, the difference will be smaller. This is not even close. Buy the RAAMmat BXT.
If you only needed 100 square feet:
RAAMmat BXT $198.00
eDead v1SE $171.00
That's just $27 dollars.
If you really need to do this in the absolutely least expensive way and are not convinced or concerned by the demonstrated inferiority of asphalt based sound deadeners, go to Home Depot or Lowes and get a roll or two of Peel & Seal. This is the least expensive option and you won't have to worry about shipping costs. I can see no difference in Peel & Seal and the asphalt based aluminum skinned products in this review. If you are going to live dangerously, do it right.
I hope this helps.
