Need an insulation solution for your van conversion? 3M™ Thinsulate™ Insulation absorbs sounds to provide superior acoustic control in vehicles. Automotive acoustic insulation can be used for a variety of sound management applications. 3M™ Thinsulate™ Insulation has extremely efficient sound absorption properties.

3M™ Thinsulate™ Insulation is a unique non-woven acoustic absorber composed of polyester and polypropylene fibers. The polypropylene fibers are extremely fine, producing a high-energy absorption characteristic with low weight. The polyester fibers are added to strengthen the web, while the scrim protects and contains the fibers. This SM600L insulation is the thickest SM-series Thinsulate acoustic insulation available.

3M™ Thinsulate™ insulation applied to automotive interiors reduces interior noise for a quieter, more comfortable ride. 3M™ Thinsulate™ acoustic insulation is made from a unique combination of fine microfibers that absorb high frequency noise and thicker fibers that provide recovery and loft. It is compressible, lightweight, and conformable.
