3M™ AU1320 Thinsulate™

3M™ Thinsulate™ Acoustic Insulation AU1320 is a lightweight, high-performance solution for automotive NVH (Noise, Vibration & Harshness) challenges. Engineered with a blend of fine polypropylene and polyester fibers, this non-woven material delivers superior sound absorption, particularly in the mid-to-high frequency ranges—critical for creating quieter vehicle cabins.

Designed for flexibility, mold resistance, and installation ease, AU1320 is the go-to solution for OEMs seeking to reduce vehicle mass without compromising on acoustic comfort.

Where to Use 3M™ AU1320 Thinsulate™ Acoustic Insulation

Ideal for reducing cabin noise and vibration transmission, AU1320 is recommended for a broad range of automotive applications:

  • Door panels

  • Headliners and instrument panels

  • Parcel trays, pillars, trunk liners

  • Wheel wells, underbody, under floor panels

  • Dashmats and carpeted areas

  • Variable cavity zones (consult for suitability)
