The Livingandhome Self Adhesive Aluminium Foil Insulation is a great heat insulator and sound suppressor. Thanks to the thick and high-density middle foam layer, it can greatly reduce the vibrations of vehicles or the rattling of loose metal parts. It also does an excellent job of decreasing road noise while improving the internal audio quality inside of vehicles. You can apply the foil over your vehicle, from the trunk, and tailgate to the doors to achieve an overall outcome.
