## Features

- Package Includes 5 sqft (5 -12” x 12” Sheet) GTMAT Quadro, GTMAT Degreaser, 2 White GTMAT Decals, Easy to follow Installation Instructions, Toll Free Tech Support
- Layer 1 - 3/16" Foam damping Material - This additional layer of damping material helps to reduce back wave and increase overall acoustic isolation and thermal insulation.
- Layer 2 - 60 Mil Butyl Layer - This butyl layer absorbs the vibrations of the aluminum layer with which it’s in contact. It provides additional damping and decouples the aluminum layer from the foam layer. This layer also provides the bond between the foam and aluminum layers.
- Layer 3 - 4 Mil Aluminum Layer - This aluminum constraining layer helps to mold and conform to interior surfaces. Additionally, this layer helps to increase the damping performance of the Butyl Layer as well as reduces undesired vibrations.
- Layer 4 - 60 Mil Butyl Layer - This self-adhesive butyl layer absorbs the vibrations of the surface with which it’s in contact. It provides damping and decouples the contact layer (IE: Metal, Wood, etc...) from the aluminum layer.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Super great product.
  

*by P***V on Reviewed in the United States on July 22, 2017*

Absolutely great product.I have a 70s chevy. I cleaned and degreased the surface of the car. I had trouble peeling off the plastic layer of the GTMAT in high heat temperature but it peeled off easier in the cooler mornings temps.It applied to the surface super easy. No issue. I cut it to shape as needed. No problems what so ever. I plan on ordering a larger package today.Instant difference in acoustics and dead road noise.
