This has transformed my daily commute, allowing me to enjoy music and conversations without the intrusive background noise. **Installation**: Installation was straightforward, thanks to the product's design. The material cuts easily, which allowed me to tailor it precisely to the floor contours of my car. The self-adhesive backing is strong and adheres well to the car floor, ensuring a secure fit without any additional adhesives. **Material Quality**: The quality of Silas Sound Deadening Material is top-notch. It is thick and dense, which is key for absorbing sound and vibrations. Despite its thickness, it's surprisingly lightweight, so it doesn't add much weight to the vehicle. The material is also resistant to moisture and temperature fluctuations, making it durable for long-term use in various climates. **Impact on Driving Experience**: The installation of this material on the car floor has significantly enhanced the driving experience. The ride feels smoother and more refined, as the material also helps in damping the vibrations that travel through the car's structure. **Value for Money**: Given its high quality and the substantial improvement it brings to the comfort of driving, Silas Sound Deadening Material offers excellent value for money. It performs on par with, if not better than, more expensive brands in the market. **Overall Verdict**: Silas Sound Deadening Material is an outstanding product for anyone looking to improve the soundproofing of their vehicle. Its installation on the car floor has made a noticeable difference, creating a quieter and more enjoyable driving environment. I highly recommend it to all car owners—it’s a worthwhile investment for enhancing your vehicle's interior ambiance.
Review: This works! - I used it to line the interior plastic rear panels and some under seat plastics in my Polaris Xpedition. Was it a lot of work? YES. Was it worth it? YES. This is good stuff, believe me. It is thick, has superior adhesion to others I've tried on other units in the past, and definitely quieted the drone of that engine packed in right behind my 2 seats. As for price, well, I guess I figured it was worth it because I bought enough to really do the job. I even put some on the exterior of the back panel behind the seats and have seen ZERO failure even though it's exposed to the heat of the engine and the mud and water of our rides. It probably doubles as a heat insulator to keep the AC from having to work too hard, which is just an added benefit for us. Noise was our main concern, and this tackled it. If you are thinking of doing this, don't think twice about this stuff - just get it!

## Questions & Answers

**Q: Can you paint the outside of this product?  Looking for something to line the inside of the cabinets in my Motorhome ti help with heat**
A: I would not paint it. It is a sponge foam. The lighter 80mil would be better to paint with the aluminum backing. Be sure to use high heat paint

**Q: What vwlse should bebused with b this**
A: I used fiberglass suspended ceiling tiles. They are somewhat rigid and easy to cut to fit. They hold their shape better than fiberglass bats will over time in a shaking, vibrating vehicle.
Styrofoam will squeak and drive you crazy.

**Q: Does it not release any smell or odor what so ever, if parked outside all day in the scorching tropical heat from the Caribbean?**
A: unfortuanty I have NO IDEA how hot the Caribbean sun gets.....We never noticed qy smell ...

**Q: Do they have an unbranded version? considering a product like this for a jeep hard top and would much rather have a solid black appearance.**
A: The fiberglass is yellow and the plastic covering on all of it I've seen is white/off white.  I believe you would need a thin plastic or cardboardy headliner.  I haven't used this on a jeep.

*by J***. on June 7, 2024*

The Siless LinerPRO 2in1 200 mil (5mm) soundproofing material has truly exceeded my expectations in reducing road noise and heat in my car. Installation was a breeze using scissors or a blade. The flexibility of the material allowed for easy cutting and shaping to fit into various spaces in my car. Plus, the self-adhesive backing ensured a secure and hassle-free application.
