Product overview

The Hex Pak is the go-to option when an installation needs a little extra Dynamat beyond what a larger kit provides, or when treating a single targeted area such as a floor pan section, a trunk floor, or a door cavity. One 457mm x 812mm sheet covers a useful area at a practical size for most targeted applications. Dynamat Xtreme deadens panel resonance and vibration across all standard vehicle surfaces including under-hood applications, reducing road noise and improving the acoustic environment for in-car audio.
