3M™ Thinsulate™ Acoustic Insulation TAI2047, 1520 mm x 92 m, 1 ea

Designed for Automotive Acoustic Performance in Narrow Spaces

Part of our TAI family of acoustic absorbers for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TAI2047 is a very thin, low density (21 kg/m³) mat insulation. It is an excellent NVH material for applications where noise and mass reduction are major goals. Its internal web features thick and thin fibers and is designed specifically to absorb vibration and help reduce unwanted noise from traveling throughout vehicles. This thin 10 mm mat is excellent for sound reduction in narrow spaces and other applications where very tight tolerances are specified.

Built for Lasting Noise Absorption

The internal web of the product is composed of a combination of polyester (PE) and polypropylene (PP) fibers. The PP fibers are extremely fine, allowing for high energy absorption without adding weight. The thicker PE fibers add loft, strength and stability to the web. The web surface has been calendered on both sides for durability.

Properties of 3M™ Thinsulate™ Acoustic Insulation TAI2047

This acoustic insulation mat material has a caliper of 10 mm and a basis weight of 210 gm/m². Fiber mat is calendered on both sides for added durability and resistance to abrasion.

Compressible and Conformable for a Range of Applications

3M™ Thinsulate™  Acoustic Insulation TAI2047 is designed for excellent compressibility and recovery. This is ideal for application to vertical surfaces in vehicle cabins, such as inside door panels and for stuffing pillars. Its light weight properties also make it effective for non load bearing horizontal surfaces, such as package trays, luggage compartments and headliners, for extremely consistent noise absorption throughout the application.

Our Thinsulate Acoustic Insulation TAI2047 can be processed using conventional techniques such as die cutting. It attaches easily using ultrasonic welding, hot melt adhesive or mechanical fasteners.

Recommended Applications:

• Narrow spaces with tight tolerances, such as headliners


• Instrument panels and other areas where contact can inhibit proper sensor operation


• Applications requiring proper operation of seat belt and other mechanisms


• Applications requiring proper airflow or pressure release


• Vehicle pillars


• Instrument panels


• Parcel trays

Reasons Why Automotive Manufacturers Choose 3M™ Thinsulate™ Acoustic Insulation

• Quieter Vehicles. Provides highly efficient acoustic absorption, particularly in middle to high frequency ranges.


• Lighter Vehicles. Thinsulate acoustic insulation products are made from lightweight polyester and polypropylene non woven fibers. 


• Easy to Install.Lightweight and easy to handle compared fiberglass, shoddy, felt and PET.


• Mold, Mildew and Moisture Resistant. Install just the insulation – there’s no need for an additional waterproof layer during application. Thinsulate acoustic insulation is also resistant to mildew growth, reducing the risk of offensive odors. 


• Efficient Assembly. Attach this acoustic insulation using a variety of methods including ultrasonic welding, double sided tape or mechanical clips.


• Manufacturing Support. Thinsulate acoustic insulation is supported by a
