cartunez2004 Posted September 28, 2007 Author Report Share Posted September 28, 2007 Its the same thing sept the top one I got from doug instead of foil it has thick fabric it seems to do really well. Ive got flowmasters dumping out under the cab and I can barely hear them. The bottom stuff is another form of peel and seal its more splash guard sealer its rubber and sticks super good but your gonna need 3 layers to = 1 layer of dynamat I ended up putting 2 more layers of the fabrick stuff over the top of it. so what is it called and does it getting rid of noice and where can u get it and how much Quote new toy 97 chevy s10 ext cab bagged 22s system (coming soon ) 4 soundstream t4-15s walled 2 concept 2410 mono amps REFS http://www.stevemeadedesigns.com/board/ind...hl=cartunez2004 http://caraudio.com/forum/showthread.php?t...ht=LOUDCARTUNEZ Link to comment Share on other sites More sharing options...
Guest MegaloManiac Posted September 28, 2007 Report Share Posted September 28, 2007 so what is it called and does it getting rid of noice and where can u get it and how much you want to have a foil backing. heres a good explanation "There are a few reasons. Vibration dampers work best when you have a viscoelastic material (the butyl adhesive) between to fairly rigid layers. One is the sheet metal of the car. Aluminum foil provides the other. When the panel and adhesive are moved by sound energy, tension between the adhesive and both surfaces converts the movement to heat. Two surfaces work better than one - the concept is called constrained layer viscoelastic damping (CLVED). Google those terms and you'll get as much information as you can possibly use. In addition to working as a vibration damper, sound deadeners also work as barriers to actually block sound. Barriers work best when the sound has to move through layers of very different densities. Mylar is to close to the adhesive to do much good. Final, butyl adhesive can burn. Covering it in aluminum foil makes it self snuffing. Mylar also burns, so it can't provide that extra measure of safety. All of these points are publicly known and fairly easily discovered. The fact that some companies still choose to cheap out with Mylar tells me they aren't a company I want to buy anything from " Quote Link to comment Share on other sites More sharing options...
