Bulk sound mat...
 

The retail prices around here are pretty high. I'm going to see what it costs to buy it right from the source.

Waiting on a couple price lists. I'll keep everyone up to date on the prices. One company asked if i wanted a custom logo on my roll. A diesel bomber logo would be kinda cool :c:

I have 2 cars and 3 trucks to do. Here are some of the wholesalers.....

ok, here is the price for a roll of 2.1mm (.82) 18" x 20' $49 bucks

good deal?

You might be able to get a square foot of Dynamat for that price, Seems decent if it works well.

I have been thinking about LizardSkin. Have to spray it on and I'm not sure if that would be easier or not in the end.

yeah i don't think that's such a good deal. I did find 20sq feet of 80mil butyl for 350 bucks on ebay. I'm the kind of guy that needs some proof. So i did buy this DB meter for before and after.

OK, i got them to drop the price by another 10 bucks a roll. I'm going to order 3 rolls and see how it is.

At least with the DB meter i will have some proof.

I am very interested to see your results. I Have a Db meter app for my phone. I know its not accurate, but as long as it records difference, there is a difference. I need to do at least the back wall in my truck. Nothing but tin behind the rear seat. :td:

So here is the place i'm talking with.

Wholesale price for .80/2.1mm 18" X 20' (32sq feet) is 40 bucks USD + shipping

Shipping is ten times more than the product. Would have to order a shipping container to make it worth it.

:argh:

Dang.

I just called a local supplier. $106.03 for a 24" x 48" of DynaMat:scare2:

call these guys.

They live in AB!

Nice! I'll have to give them a call, during there extensive hours. 10am - 4pm, damn slackers :ha:

LOL, they don't work in the patch, that's for sure.

Woah....guys....

Watch what you are getting. You need a butyl based deadener. Also need to make sure the foil/vinyl is rigid.

If you want inexpensive deadener that is great stuff.....look into Audio Technix and Murdermat.

I use AT in my personal vehicles. Wouldn't hesitate to recommend it to anyone. Actually looking to distribute their products in the spring if all goes well. They have great customer service and products at great prices.

Thanks for the heads up! You noticed a significant difference with the stuff?

Yeah there is a decent difference with just the deadener. But in order to do it the right way, a guy needs to do all 3 steps. Deadener is just one step in the process.

Step 1 - Remove/Lower resonance of panels - adding mass/changing the resonating to heat instead

Step 2 - Decouple the panel from the sound barrier - Closed cell foam allows very little transferance of vibration to sound barrier.

Step 3 - Sound Barrier - MLV (mass loaded vinyl) is a very heavy, dense sound blocker. If we could use lead, we would. But it is impracticable. This is available in 1 lb/sq ft and 2 lb/sq ft weights.

By using these 3 steps properly you can have similar quietness of luxury sedans. It is a lot of work, but well worth the results.

Thickness is something that comes to mind. If these layers get too thick, panels may not fit on as well. I was planning on making a tub, so to speak, or a sounds deadening product. From the bottom of the windshield down, along the floor, and up to the bottom of the rear window. There is currently nothing below the rear window, not even carpet. Then do the doors up to the windows.

Yeah, panel fitment is usually a lot more sung with everything underneath.

You also must remember that you are doing the outer door skins with deadener, inner sheetmetal with deadener, the ccf is very thin, and the mlv is about an 1/8" thick.

If you are bored around Red Deer one day, hit me up and I can give ya an example. I have deadener/foam/mlv on my floor and back wall, and deadener on doors right now. Carpet is out. Just seats at the moment. Also have deadener under the headliner.

meh, this stuff isn't rocket science. How do you think dynamat started? They went down to the lumber store and bought window tape and roofing quick flashing. I bought the sample pack of B-quiet and it's the same stuff i install on houses everyday.

BTW, even the good butyl mats have 20% asphalt. All of the mats need a primer IMO to stick. Without a primer it holds 3 lbs per inch. With a primer it's over 90.

Yeah and B-Quiet is not a product I would recommend. Yes deadeners started out 15 years ago totally asphalt based. There is a reason new products come out. Deadener is not the same thing it was back then. Peel and Seal is not good for your vehicle.

Also I can tell you that not all mats have "20% asphalt" in them. Yes there is an adhesive, and no you don't need a primer for them to stick.

I could get you the chemical breakdown of some of them, but it is proprietary, and I am not authorized to release that information.

Please do not think that today's deadeners are anything like your window tape and flashing, because they are not.

No, they're not exactly the same. But they do work on a budget. But sheets of aluminum faced pure butyl is the same stuff. You can buy them from just about any industrial plastic shop.

And lets face it, the mat isn't the biggest step anyhow. The closed cell foam and MLV is what makes the biggest difference.

The sound mat game has to be one of the biggest pissoffs to me. All these deadener dealers are just middle men talking smack about each others product. They all outsource the product from overseas and label it as their own.

And what audio company doesn't? Everyone offshore their amps and subs and speakers.....why is deadener an different?

Because everyone has different amps and speakers. This is one of the reason i buy used amps that were built in the USA back in the day.

All this sound mat is the same product from a couple different sources. Different thicknesses are the only difference.

Different compounds used in the butyl mixture as well. Those are actual proprietary. You can be assured Second Skin does not have the same content as AudioTechnix, and both of them are much different than B-Quiet.

Oh come on. This product is a one trick pony.

Comparing this product mat to mat or butyl to butyl is like comparing trojan to durex condoms. One is always claimed better than the other. I can't tell which one and neither can my dick. Nor does my dick care. And how much better is it? 1%? 2%? 3%?

I've yet to see any REAL percentage of proof that Mat A is better than Mat B or C or D and so on all the way to mat Z, because there is that many one trick pony choices.

You know what......you must be right. All the poor suckers in the world who buy anything but the cheapest mat on the market.....

I know I have had many different deadeners and can tell you the difference over time. Some stick, some don't. Some harden and turn to rock, and some don't. Some keep working, and some don't. You feel free to think what you want, and I'll stick to what I know.

If anyone wants good info on deadener, feel free to pm me. Otherwise make sure you trust everything you read on the internet.

I won't be replying here in this thread any more.

Oh and here - Dynamat alternative? - Competition Diesel.Com - Bringing The BEST Together you don't seem to know anything about deadener, and now you come here to seem like an authority.....

i'm not the authority on it by any means. I've been doing my homework on it and forming opinions.
