Dynamat/ sound proofing
 

I am looking on ebay at the zillamat- dynamat knockoff. Has anyone used this brand? how many square feet will i need to do the firewall,cabfloor, and in the doors? maybe behind the gas tank? should I go with the 50mil or 80mil? thanks in advance

I used some stuff I got off ebay, called Brown Bread that works good. Did it in my Chevelle and my 72 GMC truck. It was reasonable too.

Re: Dynamat/ sound proofing
 

Ditto on the brown bread. It was quite a bit cheaper and someone had lab tests showing it was at least as effective, maybe better. Can't remember right now

Re: Dynamat/ sound proofing
 

i heard that he brown bread is under a different name. can you still get it?

Re: Dynamat/ sound proofing
 

I just searched ebay for Brown bread and couldn't find it. Maybe so.

Just found it, it's now called edead Xtreme sound deadener. Comes in 2 rolls. I did the floor and doors in my 66 Chevelle and the floor in my 72 GMC with it.

I used 50 mil FATMAT but it's probably the same as zillamat. 65 sq ft did floors, firewall, behind the tank and under the headliner. Still need to do the doors, but the 130 sq ft bulk pack was $129.00 vs $1200.00 for Dynamat and I have enough left to do a double layer on the firewall, doors and floor.

This is what I went with...I bought it off ebay with free shipping. I think 50 sq ft. JFYI

Anyoone have a guess as to how much I would need to do a suburban?

Re: Dynamat/ sound proofing
 

Ivw used some stuff called Peel and seal its in the roofing section at home depot looks just like everything else avaliable and i have had good results. Its pretty cheap too. comes in 6 inch x i think 15 or 20 ft rolls

Re: Dynamat/ sound proofing
 

2 rolls with some left over, i did the entire inside of my 71' including the lid

Re: Dynamat/ sound proofing
 

So a 100 sq feet total? I'm assuming you did the inside of the doors also.

Re: Dynamat/ sound proofing
 

I'm not sure if you're looking for quality or price. However, if you're looking for quality, go with Second Skin Audio's damplifier. I used some of that ebay stuff on my S10 blazer a while ago, but for my '70 I decided to try out some more quality stuff and what a difference. I used two layers of the Ebay stuff on my Blazer and it still didn't filter out as much noise as one layer of the Second Skin. I'm going to try out the Second Skin luxury liner next, supposed to be some awesome stuff when put on top of the damplifier.

Re: Dynamat/ sound proofing
 

yes. you can see it in the first pic I posted on the inside of my doors. By doing the whole inside of my burb it made such a HUGE difference, we can now run down the road and talk normal. I highly recommend it.

Re: Dynamat/ sound proofing
 

I just wanted to toss in my 2 cents.. Whatever brand you use make sure its butyl and rubber.. The oil based products commonly used will work but no where near as effective sound wise and is easily affected by heat. I myself used a product by Second Skin and it is very high quality and alot cheaper than Dyna. Again butyl/rubber the more rubber in the butyl the better. As any ahesive gets warm it will lesson its affectiveness against sound. There have been many tests done with many different products and this one stood up with the best and for the quality the cost is not bad. I wont use anything else. My brother is a sound system installation tech and is very anal about sound perfection, he pointed me in this direction.

Ahh yes Nova70 has used it I just noticed.. It is great stuff.

That is funny, I used the same thing. They also sell it in the window section. It is flexible flashing and costs about 1/10th the cost. Poly backed butal rubber with one sticky adhesive. A common brand name that is made right here in Denver is called Protecto Wrap. Grace also make a product in full sheets called bituthane (sp?) branded as Grace Ice and Water Shield or something like that.

The basic concept is the same, increase the mass of the sheet metal with a substance that has insulating properties. The products above have that same attribute. I used 1 roll for ~ 6 bucks to do the inside of the doors at the same time I did window rubber. I could definitely tell the difference when I slammed the door and going down the road.

Not sure if I am off topic, but just wanted to share my experience as well. Good luck!

Re: Dynamat/ sound proofing
 

I used eDead, it uses the same butyl as Dynamat and costs a fraction of the price. It does a great job and if needed, can be layered multiples as well. My doors shut with a thud now instead of the tinny metal sound, and the tunes really crank without rattles!

Re: Dynamat/ sound proofing
 

I was thinking of getting some of the padding that goes under laminate wood flooring at lowes home depot. Anyone else think that may work?

Re: Dynamat/ sound proofing
 

i dont think so but if you try it and it works let me know i can dig scraps out of the dumpster by my house

Re: Dynamat/ sound proofing
 

If you bought it from that site you got ripped man. It's cheaper straight from the Second Skin site. EDIT- Just realized that's the Pro. Same price.

I'm tellin' you guys, if you want quality stuff, there is no better. Dynamat isn't even as good as this stuff.

Re: Dynamat/ sound proofing
 

IMO fatmat blows.Best budget peel n stick ive used is RAAMmat.I highly suggest not using fatmat if you plan to keep the truck over 2 years.Just my .02

Re: Dynamat/ sound proofing
 

I used a product called window wrap.
