Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!
