3M Thinsulate is an excellent sound absorbing material (particularly on medium to high frequency, very effective in reducing wind noise) which has several advantages over other material.

1. Much better sound absorbing performance compared to other material like felt and Insuxxx/Superxxx.
2. Act as a thermal insulation material too (Good feature especially when you install it on the headliner / roof)
3. Light Weight (Less weight added).
4. Compressible (Can be installed in tight area like door trim, etc).
5. Will not absorb water (No need to worry about development of mildew & odour).
6. Easy to handle (Can be cut by using normal scissors & installed by using hot melt glue or double sided tape).
7. Pass Flammability Test FMVSS302, flammability = 0mm/minute
