- Global portfolio and technical expertise help ensure you choose the right solution to meet your goals
Our 3M™ Thinsulate™ Acoustic Insulation TAI3027 is a thin, lightweight mat material engineered specifically for automotive sound absorption. With an overall thickness of 21 mm and a basis weight of 330 g/m2, this material features excellent compressibility and recovery that allows it to fill spaces more completely after installation. A 100% polypropylene scrim reinforces the web on one side.
Suitable for applications in vehicle cabin and luggage compartment interiors
A Material Designed for Automotive Acoustic Performance
Part of our family of acoustic absorbers for automotive OEM, 3M™ Thinsulate™ Acoustic Insulation TAI3027
(PDF, 506.1 Kb) is a very low density (15 kg/m3) mat insulation and 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.

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 lightweight reinforcing white scrim on one side is made from 100% polypropylene non-woven fabric for durability.
Properties of 3M™ Thinsulate™ Acoustic Insulation TAI3027
This acoustic insulation mat material has a caliper of 21 mm and a basis weight of 330 gm/m2. Fibers are protected by a single scrim on one side.
Compressible and Conformable for a Range of Applications
Thinsulate Acoustic Insulation TAI3027 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
(PDF, 473.6 Kb) 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 TAI3027 can be processed by conventional techniques such as die cutting. It attaches easily using ultrasonic welding, hot melt adhesive or mechanical fasteners.
Thinsulate™ materials come in a range of thicknesses to suit different frequency needs

The Science Behind How Thinsulate Acoustic Insulation Absorbs Noise
- 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 our 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 global network of 3M experts. Custom die cutting services are available.
All sound is transmitted through the air as waves. These acoustic waves oscillate at differing frequencies. When oscillating waves contact the fine fibers of our Thinsulate acoustic insulation, the resulting friction turns their acoustic energy into heat. The heat irreversibly dissipates and reduces sound. As a result, 3M™ Thinsulate™ Acoustic Insulation applied to automotive interiors reduces interior noise for a quieter, more comfortable ride.
