how much sound deadener per sq ft, etc do you need to cover the whole cab interior? i want to eliminate as much noise as i possibly can...

It's a heck of a lot cheaper ($16 a roll). Dynamat is ridiculously over priced. You pay like $150 to do a 3 foot section. Or something like that. Google B-quiet for another good alternative to dynamat, that one's actually made for autos.

wow that's a huge difference i heard of using that stuff before. does it actually WORK?

FYI, if it comes in a roll, it is roofing material. Avoid it. Roofing material is not nearly as effective and STINKS in the heat. You'll know you made a mistake when you return to your car after parking it in the sun on a hot summer day.
Yes dynamat is very over priced, but who in their right mind pays retail? Check out some of the the Dynamat Xtreme prices on eBay...MUCH BETTER.
When you take shipping into consideration, this represents one of eBay's better deals on Dynamat:

I imagine, you would need two of these to get good coverage of your doors and floor.

i' thought so... i've seen some dynamat wannabe generic stuff, didn't know if that was worth using or not. my cousin owns creative car tunes so i can get the stuff, and i have an account with autoloc so i can get stuff at wholesale... just didn't know what to use...
-
There's other stuff that works just as good that's cheaper. Take a look at B-quiet and Second Skin.

bigblock73 used b-quiet on his:

I should clarify that I am not down on products like B-quiet, Second skin, or Cascade (which is apparently the best on the market). I just wanted to make it clear that you can do MUCH better on Dynamat pricing, if you want to go that route. Just steer clear of anything that comes in rolls (maybe it's not always the case that it will be roofing material, but why risk it). I know someone that deliberately used roofing material and he had a heck of a time getting it all off after he realized his mistake.

i saw some stuff on ebay when u do a dynamat search so i knew there had to be other brands out there that were the same thing... i heard of the b quiet stuff, i just want my cab as quiet as i can get it...
-
i used b-quiet for my cab also, and i must say i really like it. The sound drop is fantastic, even with my louder exhaust, and with the windows up you barely hear outside. Windows down gives the pleasant sound from outside, so its not as droning as it used to get going down the road.
Mine came in the roll, but there is no smell at all(i think its almost all butyl rubber instead of asphalt) and i could not be more happy. also i was able to turn my radio down from 35 to 25ish as there was less noise in general to overcome.
heres a pic of complete(minus the back wall i did that afterwards)

Hey Armor, is B-quiet all gooey on one side, like dynamat? Or is it more of a foam?
-
it VERY sticky, but it not runny or anything, if it touches the surface it will stick well, but you can pick it up a bit if needed, but once its rolled down with a little roller, it doesnt come up at all. SIDE NOTE- gun wash will get it off panels, if like me your attempting to get factory buckets in after finishing the floor.
-
I used some stuff that I got off of e-bay called fatmat. Like Armor said I could not be happier with how it turned out. It is like the dynamat, it is sticky on one side and after installed it cut out the noise and cut down on the temperature in the cab.

that's acutally one of the kits i was looking at. how much did it take for you to finish your cab? or which kit did u get?
-
Its cascade or nothing at all for me..its the best sound dampener brand you can buy, hands down, and is priced comparably to original dynamat. My maxima will receive 360 sq feet (2 layers over most areas, 3 over the worst spots, 1 layer on the hard to reach areas), I'd aim for 200-220 sq feet for one of these trucks.
FYI, most products come in a roll, second skin is notoriously bad about smell. Stay away from e-dead as well.

I didn't realize this. All I've ever seen offered by brands like Cascade, Second Skin, and Dynamat are pre-cut sheets. But I did know that asphalt-based roofing material pretty much always comes in rolls. So, I figured... :-[ My mistake. Thanks for the heads up.
-

If I remember correctly I bought the $90 kit. I cant remember how many square feet it was. I covered my cab from the rear window to my firewall, I covered the trans tunnel and the floor under your feet twice. I have been very pleased with it. A friend of mine also bought this kit and done his truck with the same great results.

Can you provide a link to the Cascade that you are talking about? Looked for it but came up empty handed. All the stuff I found seemed to suggest that it had changed it's name to something else?

I tried both FatMat and Rammat on my truck(2 layers over everything). THEN I used liquid sound deadener over top of that (EDEAD v3).
Between fatmat and rammat, I would go with rammat, it is not tar based like some of the others, its butyl(sp?), supposedly, and has no smell to it.

Yeah I been researching all this a lot lately. Found out you want to stay away from asphalt based products, you want to go with butyl based. Dynamat Extreme is pretty much the king, that's why everyone has heard of them. But you are going to pay top dollar for it. I think it would take a little over $500 to do one of our trucks with dynamat. Brown Bread is still around in the form of B-quiet, it's named just changed. But the only B-Quiet that you want to mess with these days is B-Quiet Ultimate. The B-Quiet extreme is asphalt based, there is more than a few reasons why it's being phased out. Also, over at the car audio forums they say to stay away from e-dead, and FatMat. That seems to be the general idea over there.
-
The problem with all these tests I've seen on different deadening products is that they show you a bunch'a charts that tells you how one product is better than another; however, your ears cannot discern any difference between no sound and what a chart may tell you. If something is 100% quiet how can 110% quiet be better? It simply can't -- your ears can only register so much.
These various deadening companies just want to sell us their products so they will say whatever they need to say to sell it, whether that means degrading another companies product or spreading rumors to make people question certain products.
I used Quick Roof on mine and could not be more happy with it. I have had it installed for 2+ years. I saved around $450 by using it. Everyone needs to do what they think is right for them; however, from my personal experience, I will not hesitate to use Quick Roof again. I have had no smell issues and it is simply not possible for any product deaden any further as I can't hear my engine running -- I see no possible way to be quieter than no sound.

i'm painting the truck black. so even from a restoration perspective, if i were to go looking to buy another one of these trucks, and someone said they used roofing material, to me that would suggest that every other project was done having the corners cut. i wanna save some money if i can, but when it comes to dealing with a potential hassle of my cab smelling, and then having to remove it and redo it down the road, i'd rather spend the extra money up front. i wanna do things the right way. if it costs mroe so beit. i'd rather save the money and go a cheaper route if i CAN, just because it frees up extra dollars towards other issues that need addressed. i'll probably go with dynamat, my cousin owns a car audio shop here that's done some of the sickest imports known in that industry. he says dynamat, and 200 for the extreme to do my whole cab. so if that's a good deal, then so beit. i just wanna spend my money the smart way.

vb2-hd comes in sheets now, I called my dealer that I bought mine from before to ask why they made the change, it was partially because its cheaper to ship sheets, than ginormous rolls.
vb2-hd is better, not so much because of dampening level, as much as overall product quality and properties. Its much more stretchable than any other product I've handled, its very lightweight compared to pure butyl or asphalt products. Its more conformable to tight areas, ideal for the small spaces behind inner door panels. It even sticks reliably to the roof. It has one drawback imo, and that is the fact that it generates a small amount of heat as it absorbs vibration. In almost all cases, this doesn't really matter, but in a car that sees TREMENDOUS audio vibration (not a buzzy trunk, but rather a windshield that nearly vibrates out of its seal), it can increase the inside temperature noticeably.
-
I would go with secondskin. Their products are amoung some of the best in the audio industry. In terms of keeping sound in the car, they prolly rate second. Check with all the SPL and SQ guys. They all love Damplifier Pro. they can't get enough of it. it will be what I use on my crew when I get to that point.
-
The fatmat has been in my truck for almost a year now and I have never had an issue with smell. It has set all day in the sun and heat at car shows and still no smell. I also have a friend who used the quick roof and I would like to add that he has not had any problems with smell or anything else for that matter. I think it is all a matter of opinion on which product is better and in my opinion I would use either one of these products. In fact I will use one of these in my wifes 54.
-
It is totally a matter of opinion. As I stated above, people have to use whatever it is they think will work best for them. All we can do is to listen to the people who actually have experience with the various products and base our opinion on their personal results. Ideally, if we find someone who has used a particular product, we see how it has worked for them. This seems a much better option than listening to opinions and hearsay from third parties and/or salesmen.
With that said, when people start telling someone who used one product over a different product, for whatever reason, that they in some way did in inferior job or are less smart, especially when they have absolutely no experience with said product that was used, that's getting a little too close to the line of calling someone a liar. Especially when the person who used the product in question cannot be more happy with their choice of product, the way that product works or the fact that said product saved them a ton of money.
It doesn't bother me to buy the Walmart brand. Furthermore, I don't taunt the people who decide paying quadruple for the name brand for a product with similar results is the best for them. But it sounds like the ones buying the name brand like to make themselves somehow superior to the one's who do something different than what they have decided is the best. Maybe they'd be wise to realize what is best for them is not necessarially the best for everyone else. Perhaps there is a difference between spending money the smart way and spending money the wise way.
-
I agree with Goat, I would find the one that meets all your criteria. In the end, they are all just insulations.
-
I also look at it like this....there is dampening....which is what most sound deadeneres are (As stated, use what you feel best). And there is noise blocking foam. For best results, they needs be be used together.
-
my end goal is a quiet cab. i haven't even began to worry about the stereo, that's the last thing on my mind. i'll probably go with a dvd in dash setup or something anyway. or have a console fabbed up and put it there. but i want the cab quiet. like, lexus quiet.
-
If you combine the foam, the butyl goo-mat, and the vinyl barrier you will put the best lexus they make to shame.
-
well that's my goal. i hate noise. i wanna do the one piece windows at some point too to avoid the smaller window from making noise.
-
Me too. I can't stand that highway tire noise, or road noise or engine noise. To me it can make any vehicle feel cheap and poorly made. It's fun to eliminate it though.
