Thermal Management in the automotive interior

Thermal Management for Automotive Interiors

CONTACT A 3M EXPERT

A vital element for passenger comfort

You can make your interiors visually striking. You can make them ultra-convenient and functional. But unless they’re comfortable, they still won’t make the grade. It’s essential to manage interior temperature – for more robust passenger experiences, and for overall vehicle efficiency.

3M delivers with our acoustic insulation material. Even as it absorbs NVH, it creates a thermal barrier that makes it easier to maintain desired temperatures in a range of environmental conditions. We also provide engineered films to control solar heat buildup through automotive glass.

For today’s interiors, quiet only goes so far

Discover our 3M™ Thinsulate™ Acoustic Insulation, excellent for doors, headliners, trim, pillars, consoles and instrument panels. 3M also provides materials engineered for thermal conductivity that help direct heat toward heat sinks and prevent it from entering the vehicle interior, as well as engineered films to control solar heat buildup through automotive glass.

    3M™ Thinsulate™ Acoustic Insulation

    • This trusted insulation material performs double duty for automotive interiors – it is designed to absorb sound vibrations and dissipate heat, excellent for maintaining comfortable interior temperatures regardless of the environment outside. Lightweight and compressible, the material is excellent for gap filling in voids in pillars, behind trim panels, in headliners, or instrument panels.
