I have few very long journeys to do this summer and as my car suffers from a lot of road noise I would like to add some sound insulation to my car before I go. I don't want bitumen based stuff like Brown Bread or flashing tape as I expect the car to be left for extended periods of time in very hot environments and would rather avoid any chance of asphalt smell or melted goo from sound insulation on the floor of my car.
I gave a lot of thought to Dynamat and other butyl based stuff but since I would need ef loads of it I simply can't justify the cost.
Which leaves me with two "ghetto sound proofing" possibilties:
- Dual layer of polymer-based, asphalt-free, high density synthetic membrane as used on floors ( such as http://www.customaudiodesigns.co.uk/soundproofing/t50.htm)
- Open cell acoustic foam, or as it's commonly known - a camping mat. With optional extra layer of alufoil faced laminate underlay
Does anyone have any experience with the above products or have any suggestions of how to cheaply but successfully sound proof my 'mera to Accura standards.
