I want to do my cabin. Floors, interior firewall. Not planning on doing doors.
I'll use either Fatmat or Dynamat, but I don't know how much to buy. Which of the two do people like best these days. Zach |

QUOTE(melnyk @ Aug 11 2008, 05:32 PM)  oh btw my neighbor works at the factory where they make this so i get it cheap. if it works im thinking about making pre cut pieces... Is it asphault based? If it is roofing material, then it probably is. If so, you might want to rethink it. All the better soundproofing is going away from asphault due to its failure rate. If your car sits in the summer sun, your solution may melt and come off the car. Zach |

If your car sits in the summer sun, your solution may melt and come off the car. Zach I will try to be brief...but it gets harder as I get older. Ice and Water shield (grace chemicals) is butyl based and its actually uncured rubber. This allows it to stretch around the nail heads and it sticks like glue and eventually is impossible to remove with a little bit of heat. Sound deadening is done with two approaches. One is to thicken the base metal and therefore elimintate vibration noise that is transfered via the panel. This is why trunk floors and floorboards are not just flat...they would vibrate to much. This is also why most door panels have some thickening done in the middle of the panel to negate the vibration. The second thing to stop is sound waves. Sound waves travel at a certain frequency like waves. These waves have certain spacing between crests. Certain waves can be stopped by certain materials. Not all waves will be stopped by one material... So, use rubber to not only thicken the base material, but this will also stop a certain number of waves...so it halts a certain sound spectrum. Now, use aluminum glued to the top of the rubber. This stops certain waves that the rubber wont stop. Its not perfect, but by using both rubber and aluminum foil you will stop more sound waves. I have used Ice and Water shield and it really does work fine, but I am not an audiofile guy looking for a setup for audio system that is smoking hot. Use Ice and Water shield for simple sound deadening, it works great. It has no aluminum layer, so it will not block the additional sound waves that aluminum does block. There is alot more to look at, but you can cover both sides of the firewall with ice and water shield and it will be very very quiet. Rich |
