SilessHybrid 3in1 200 mil 25 sqft Car Sound Deadening mat - Butyl Automotive Sound Deadener - Noise Insulation and Vibration Dampening Material

I recently installed the Siless Hybrid 3in1 200 mil sound deadening mat in my car, and I’m genuinely impressed with the quality and performance. The unique layering design, especially the second layer, provides superior sound insulation and vibration dampening. The butyl rubber layer is thick and adheres well to surfaces, creating an effective barrier against road noise and vibrations. Applying this mat was straightforward, and the flexibility of the material made it easy to install, even in tight spaces. After installation, I immediately noticed a reduction in noise, making my car much quieter and more comfortable. This product is perfect for anyone looking to upgrade their vehicle’s soundproofing. Highly recommended!

Well done , glue well , easy to install

Using it for my hotrod has great deadening, easy to install and looks great instead of that silver foil look of other brands

Used on the roof of my car to insulate from the heat. It works!Used a layer of regular siless sound deadener. Followed by this triple layer stuff. Then some jute insulation stuck on with spray adhesive and foil tape. Finally a layer of foil faced bubble wrap. And, of course, the stock headliner.This stuff made a noticeable difference when layered with the regular siless sound deadener. With the additional layers of insulation my AC isn't struggling as much. Prior to putting on the headliner I noticed the insulation was cool to the touch. Even in hundred plus degree weather. So this triple layer material works very well when used as part of an overall strategy.My goal is a car that's cool and quiet. I plan to buy more to do the floor and doors of the car.

Works well. Very good sound reduction. Used on floor and doors of C Class motorhome. Hoping for good heat reduction as well, but haven't tested yet. Product is much easier to install below 80 degrees F. At about 90-95 degrees F it gets so sticky that the backing paper becomes impossible to peel off. Just let it cool and it works fine again. Easily moldable into recesses in the vehicle surface.
