Dynamat: What thickness should you use? should you put over the tar on the floor should you throw away the rubber pad behind the backpad on the firewall?
I need some adivce: I want to add sound barrier under my backpad and possibly floor. I currently have the black tar floor, nothing in doors and rubber pad behind backpad which honestly has seen better days and looks pretty nasty. Should I add any sound proofing to the floor before I carpet? If so, what thickness? Also, should I throw out the old cracked and dirty rubber pad and put sound proofing on top of the firewall behind the backpad or leave it as is? Thanks in advance for advice |

Sound is both vibration and sound waves.
It’s best to use two types of material to stop most of the sound waves. Lizard skin is a ceramic paint, good for step one. Ice and water shield type self sticking rubber is the second layer. We have real estate issues, so you really can’t use anything thick like wool padding still found on high end luxury cars, it’s too thick. If you go google about this topic, google dynamat and lizard skin along with sound waves….some good learning out there |
