Printer Friendly Forum Posts - Sound Dampening!

Hey,

I was just researching this myself. From what I hear, if you dont want to use something as thin as dynamat, the best bet would be to go for a roofing material called Ice Guard.

You can always just use carpet backing, it works great, maybe even better than dynamat, but of course, the thicker it is, the better it works, and the thicker it is, the more room it takes up, stopping panels from fitting right, doors from closing, and any other problem the bulkness will add.

There is also sprey on rubber coating or rubberized truck bedliner material, but to me those dont sound like they would work very well. Not to mention truck bed coating is very potent smelling, and VERY hard to work with. It would be like soaking your car in tar.

The only bad thing that I have heard about Ice Guard, is that it is very hard to find in small quantaties. Most places will only sell it in bulk 225^2' rolls. Those 225 square feet only costs $70.00 USD though. A lot better than Dynamat at around what... .70 a foot?

Hope this helps you

Thanks for the info. I heard about using some kind of roofing material but wasnt sure what it was called. I looked in Home Depot for some but the stuff I found would have been too hard to work with and it smelled really bad. I started researching the web and found this site. www.b-quiet.com They have this stuff called Brown Bread which is way cheaper than Dynamat and is actually better. For 70sq. ft. its only $159. I could buy 140sq. ft. and layer my car twice and it would still be cheaper than just 1 layer of dynamat. So I think this is what I will buy.

Thanks for your help. Im still going to check out that Ice Guard stuff to see if its somewhat easy to work with and isnt too thick.

The only dampening material you will find that doesnt stink real bad would be carpet backing. Pretty well anything including dynamat and brown bread will stink to high heaven. The best thing to do is install it throughout the whole interrior, and leave the doors open over night in a garage if possible. At least that is what I hear.

I have heard of brown bread, but the person telling me about it said that it was more expensive than dynamat. If it is cheaper, I think I will look into that as well.

The best thing i have found to use is rubberized undercoating... this is like the bedliner material spray on. it is not hard to work with but you have to do 1 layer at a time! if you do more it takes forever to dry. i have done my whole car inside the cab and trunk using expanding foam for the open spaces inside the walls and trunk and deck lids ect. then gone over it and all metal surfaces using 3 to 4 coats of rubberized undrcoating you can get this for about $5 a can and it will take about 3 cans to do a average trunk hope this helps contact me if you need more info

i used the roofing stuff called ice guard, its really thin and flexable, its just tar with a wax paper cover really. I noticed a heuge loss in viberation with only 1 layer. But i got this stuff as a trade for a sub box i built, i was going to get brown bread becasue it he been tested and rated better and cheeper than dynamat.

p.s. , the smell goes away after a day or 2

if your going to do comps then i wouldnt skimp out on anything, the better the quality, the better the system. I used dynamat and it works awesome, i believe it wokrs better than brown bread too. i tried both and was happier with dynamat.

I guess it all depends on depends on where you live for where you can get it. But check major hardware stores in your area, and any specialty roofing supply stores. It is used to go on before shingles as far as I know in roofing.

ive used brown bred i like it allot but keep an open mind on the roofing material that was mentioned earlier i put 3 layers of it through out the car what a difference it made it does not stick as well as dynamat and brown bread but it does the job just be ready to make the roller yul be using your new best frend

This topic just keeps rearing its ugly head.

Here is a quote from me on the same topic earlier this year.

"Another trick you can do is to get some of that bed liner spray. This not only seals the box but also adds sound deadening and vibration control which helps stop fatege with the MDF, nails or screws, and glue. That's the only problem with using fiberglass resin, It fails over time. At least if the box is used hard.

If your design warrants using internal bracing make sure that you router all the edges off so that the air moving inside the box moves smoothly around the brace. I would stick to using MDF strips cut about 2" wide for the braces and make sure that the braces do not touch the woffer at all.

Most of all. Take you time and do it right the first time. Don't let your buddies rush you into building a junker box.

Using these methods you will build a box that really rocks(as long as your air volume is correct)."

brown bread actually sucks. dynamat does not smell. dynamat is the easiest sound deadener to use. I would only use extreme though...you get what you pay for here.

Thanks again for all of the input. I have decided to use Brown Bread. For $130 on ebay I can get 70 square feet plus a roller. I went on their site and looked at the comparison between Brown Bread and Dynamat Extreme and the figures on the BB looked better. Even if the BB is not as good as the DE I could cover the car 3 times for the same price as Dynamat. To me I always thought Dynamat was way overpriced, but its all opinion I guess.

There is a material called FAT Mat and it works just like Dynamat. It is exactly like Dynamat buy a lot cheaper. go to www.fatmat.com to check it out. You can get it on ebay for next to nothing

If i were to order lets say 36 sq ft of fatmat do i just take off my door panels then cut off that plastic sheet and take off one side of the fatmat that will make it sticky and then use a rollers and roll it onto my door? I have a 4 runner will this help me much? Thanks

dream it, build it, fiberglass it

I figured I would post their information about RAAMmat. The mat comes in 60mil thick and is comparitive to Dynamat, the big difference being cost. Rick sells the RAAMmat for $99 and the roll of mat is 15" wide and comes with 62.5 sq ft of material. Thought I'd pass along the information and help out one of my newly aquired (just got them to sponsor me last week) sponsors: https://www.raamaudio.com/products.htm

i just bought 100sqft of fatmet from fatmet.cim for 119 shiped... check the out!

sorry about the spelling fatmat and is from fatmat.com cal the up for the 119 price and ask them for it b/c they are having a sale

I have found that the Home Depots in the SOuthern states do not carry Ice Guard, at least here in JAx, Fl, they don't. There is a variations of it called weather Guard. It comes in a RED / white box, is 140sq ft, and costs about $45.95. I have heard it is the same stuff as Ice Guard, and from what I could tell by looking at it, is almost the same texture and weight as Dynamat. 150sq.ft. should be more than enough to deaden the whole car (I think)

But there are plenty of alternatives to sound deadening. 1) Fill all big voids (holes) with minimal expanding foam, be carefull it can and will bend the metal if not extremely cautious. 2) Silicone can be used for places that 2 pieces of metal lay over the top of each other, but don't actually connect. 3) Rubberized undercoating stinks, but it good. 4) Rhino Bedliner is great for adding a little mass which will help deaden everything it is on.

Dont have it here in ATL either

dream it, build it, fiberglass it

I bought a roll of RAAMmat from a friend who didnt need it anymore, applied some to my rear deck, and I was pretty impressed. It sticks really good, conforms to curves and bumps, and it's way more affordable than Dynamat Extreme. I think it does it's job just as good as Extreme, as I have both in my car, and the fact that it's sold for about $100 for a 62.5 sq ft. roll is pretty damn good.

Look no further, use this: https://www.abccatalog.com/store/viewitem.asp?idproduct=2579952318

Cheap, sticks like there's no tomorrow, and the company ships quick. There's an initial "tar" smell but once it's intalled and aired-out, the smell will go away. I did damn near to whole cabin of my truck (81 f-100) with only two roles at about $50 each after S&H.

Look around the site and you'll find they have it in gray and aluminum, i like the aluminum better. They also have it in different "widths" (there goes my spelling) to chose from.

I'm starting to sound like a spokesman for them so i'll end here.

I've been wanting to get some b-quiet BB, due to the fact that it was cheaper, but from reading everyones replys alot of you guys seem to use roofing, insulating products... any replys on how well this stuff really works????

This stuff work pretty good. it molds pretty good (using a heat gun) and sticks like hell, no smell after a while. Big difference in (diminished) road noise after i did my truck.

roughly how long are you talking about for the smell to dissipate? posted_image

Would applying ratt mat or dynamat or any of these roll on stick mats work good if i were to just put it on the doors of my 4runner? What would i see a difference in, road noise? Also i have Eclipse in my car and notice the outside of the back of the cars metal flexing if im outside and have it up loud, will any of these products help that?
thanks

I also have used this stuff and it works but use at least 2 layers of it and seal it to the car with a heat gun ...you can find it at any home improvement store

You get what you pay for plain and simple. If you looking for sound deading don't skimp on this or that buy the material for what it is intended for.

The only stuff that I could find locally around here was a water and ice guard, I cant remember the brand, I figured it was the same as the ice guard, it wasnt overly sticky, but it was tar on one side, so with a heat gun it should stick, but on the other side, it wasnt aluminum foil or anythign liek that, it was grip, it was basically a large shingle that was rolled into a big roll. is that was Ice Guard is? It just didnt seem like it would be easy to work with, nor did it look like it would do the job all that well... I mean, I am sure it would stop sound, but so would cement.

Soup, that stuff you got is horrible. I know, I bought a roll at Lowe's. I got frustrated with it trying to get it to stick, even with a hair dryer. I had already prepped the surfaces clean with acetone and a rag, too. I ended up only using it on the floor. I guess I figured it can't fall off there- haha. Peal-n-Seal works well. I did both doors, and had some left over. I picked up some more, and will do the hatch area when I get the chance.

That carpet backing that was discussed..........are we talking about that foam material that you find underneath wall to wall carpeting? If so, what is the best way to apply it to you r trunk lid? Spray on adhesive?

BALLGAME!!

I have used the ice guard, not on cars or anything, but on roofs, since I build build new houses and do all kids of repairs on older houses, the ice guard isnt very thick, its pretty easy to work with also, if there is a Lowes near you, check and see if they have it

live in your world, come play in mine

I was informed about this stuff from another forum here on the12volt. I recieved my order very quickly. I just ordered one 32"x54" sheet to get a sample of this product. It cost $14.62 plus shipping. That's 12 square feet of this stuff, which is the same thickness as Dynamat, for the same price as 2 10"x10" pieces of Dynamat. It sticks the same a the expensive stuff. A heat gun would be advised on non-flat surfaces.

www.mcmaster.com
At the bottom of the page you'll see "raw materialsand springs" with 'sound absorbers' just below it, click on it. It will take you to catalog page 3266, click on the catalog page arrow until you get to page 3270. At the bottom you will see a bucket of vibration damping compound and adhesive-back damping sheets. I bought the polymeric mastic sheet since it's the same thickness as Dynamat. I'm not sure about the other sheets on there though.

I bought some Fatmat, but it's only .045" thick, where this stuff is .070" thick.

Has anyone thought of using lead sheeting? comes in various weights and thicknesses and is about 1/2 the price of most other sound deadners. I am building a GMC pickup and installing a Cummins diesel (not the quietest engine in the world!!!!!) and the lead deadends the sound like no other. It has a mass about 10 times that of dynamat and the others. And just so you all know....lead is only toxic if you eat it or inhale it. You can buy lead sheeting from most roofing suppliers. It is also super easy to instal and you can cut it like butter and mold it to any shape and is only 1/32nd of an inch think!!!!!

Try it, it works great!!!!
