[QUOTE="ifandorbuts, post: 108191, member: 544034"] This material is no the same as brown bread. BB is a bitumen adheasive 70 mils thick. SSSD is a rubberized asphalt 45 mils thick, more like B-Quiet The spectrum material I am coming out with is not like anything out there. It would be hard to compare it to somthing its like this: one layer of dynamat exterem another layer of dynamat extreme with out the foil then a layer of closed cell foam all in all there are 5 layers 1. adhesive 2. rubberized asphalt 3. foil 4. rubberized asphalt 5. foam I am designin ghtis material to handle 1. vibrations. 2. heat 3. road noise 4 engine noise yet still trying to keep it light weight and thin its turning out to be wuite difficult I hope to have the prototypes done by monday, real world testing by friday, and product to sell the following week. thats like 12 hours a day work though its not easy ANT [/QUOTE]
