Sound Deadening

Does anyone have a source for inexpensive but effective sound deadening material? I want to do the rear of the cab and the doors.

I am spending enough on the rest that I am leaning on not doing it but want to do this install right...

 

I bought GTmat on Amazon because you get a lot of it for the price, it was Prime shipping, and it was thick and had good reviews. The smell was only noticeable for a day and it was very easy to deal with. Make sure you apply it in temps above 50 degrees. I was able to do all 4 doors inside and outside (see my link in signature) and the entire rear wall below the windows. I have about 10% left with 100% coverage where I used it (some people just put strips at 75% or less coverage, but I covered it all).
Here is the link from Amazon:

GTMAT 50 sqft Automotive Sound Deadener 80mil ULTRA – Noise Killer Installation Kit Includes: 50ft Roll (16” X 19’), Instruction Sheet, Application Roller, Degreaser, GT MAT Decals

80 mil thickness (the kind I used)

Or the cheaper

GTMAT PRO 50mil - 50 SqFT Car Sound Deadener 50mil Auto Noise Insulation Installation Kit (2 rolls of 16" x 19')

50 mil version

 

Thank you for the info!

Did you have any concerns about this being an asphalt based product?

I have been reading reviews and basically trying to learn everything I can about all the products I am considering and I have read that this and others like FatMat are similar to the roofing products (Peal & Seal) sold at Lowes and Home Depot.

 

I did not read that it was asphalt, but that would not have affected my decision. The reviews were good enough for me.

As for the roofing stuff, I imagine that stuff stinks. Would a company making roofing material really worry about the smell (especially in a vehicle)? I did go to my local Home Depot and they had no idea what I was talking about.

 

I decided on Stinger Roadkill, it was going to be either that or Raammat at the end of my research. Both of them are butyl rubber based and have decent prices.

 

AEmedic, did you do your soundproofing? Are you happy with the noise reduction? I'm thinking about doing the same, but I want to find out how it's working for people. Thanks.

 

I wouldn't use that peel and seal that thing dose not work.not to mention the time it's guna take you to clean that crap off ..I suggest you use a real sound deadner.it is well worth it..lessens road noise and makes your music sound better. I used dynamat extreme.bcuz I got a good deal on it..I've heard shock has a good budget soundedner .I've only used there wire tho.

 

I'm gonna do another group buy on the shok Matt which is top quality
Deadener and by no means a budget deadener. I have just worked really hard on getting the 4x4 guys the deals on it. I'll be launching a prebuy very shortly here. It's version 2 with additional improvement from the last group buy . Price will be very similar to last time and well worth the money!!! You simply cannot get any better even if the price point was over $140 per 40sqf but I'm aiming for $118 shipped in USA for the preorder

 

I ended up getting the Roadkill for $90 shipped on Amazon. That got me 36 sqft which was enough to to all the door skins and the rear cab wall and I still had a couple of sheets left over. This was the best deal I could find on "real" sound deadening! The results were outstanding!

 

I was just researching this yesterday and I found that to do the entire double cab I would need 80-100 sq ft. I was browsing around and found this:

I have heard of FatMat before and I was always under the impression that is was second behind dynamat. Is this not true? Figuring it's 80 mil think and dynamat is usually 100 mil. Am I way off and need to go back to searching?

 

I "think" that Fatmat is asphalt based...I'm not positive but I wouldn't put a non butyl based sound deadener in my truck!

 

GTmat has both asphalt and butly based deadner. check their website for which models are which.

i used 50mil GTmat on my outter door skins. there was smell for a few days.

Then i used Knu Knoceptz 100mil and 80mil for inner door skins and door panels. I also used Raamaudio ensolite.

i need to do the headliner and more of the rear cargo area. I used 2" thick hig density foam to fill the voids in the cargo area for a temp fix.

 

So I was thinking about using aluminum foil tape http://www.homedepot.com/p/Intertap...ALF201LUL2560HR/205586161#product_description and then a layer of this foam http://www.foambymail.com/VA/polyethylene-foam-roll.html to sound deaden, what do you guys think? The aluminum tape adds more insulation and weight while not containing asphalt and no dripping, running, or melting. This foam sounds like it has better qualities than that ensolite stuff and is half the price. Any thoughts are welcome.

 

Raammat FTW. I used this in my entire truck and its a fantastic product.

 

the Alum foil is only there to provide a surface to hold the Butyl together during the application process, it serves no other real purpose.

 

You don't think that tape would add rigidity to the roof? I guess there is only 1 way to find out.

 

it won't do anything, believe me. If it had any advantage all my friends and fellow members in the DB drag industry would have been all over it.

 

It won't offer any kind of improvement as far as making the cab quieter / deadening. Don't waste your TIME or money.
