**Product Review: Silas Sound Deadening Material for Car Floors** Rating: ★★★★★ (5/5) I recently upgraded my car with Silas Sound Deadening Material on the floor, and the results have been nothing short of fantastic. Here's a detailed review of my experience: **Noise Reduction**: The effectiveness of Silas Sound Deadening Material in reducing noise is impressive.

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.

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!

Enhanced Soundproofing and Thermal Blocking
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. Once installed, the difference in sound quality was immediately noticeable. It did help dampen vibrations and reduced external noise, creating a quieter and more comfortable environment. The thermal insulation properties were very important to me, and this product did deliver on that. The engine firewall in my classic car gets too hot and the cabin heat becomes unbearable, but with this product, the difference was immediate. I highly recommend the Siless Liner Pro to anyone looking to improve soundproofing and thermal insulation for their car. With its easy installation, durable construction, and impressive performance, it's a game-changer for creating a quieter and more comfortable environment.

Product Review: SilasPro 5mm Sound Deadening Material for vehicles. I recently upgraded my truck with SilasPro 5mm Sound Deadening Material on the floor, roof, rear firewall, and doors. It took 2 1/2 cases to do a complete comprehensive install. Noise Reduction: The effectiveness in reducing noise is impressive. It dampens road noise, engine, exhaust rumble, and vibrations, making my trucks interior much quieter. I can now enjoy music and conversations without the execive outside noise. Installation: Installation was straightforward. Material cuts easily, and very flexible which allows following the floor contours relatively easily. The self-adhesive backing is very strong and adheres well to anything it comes in contact with. (careful what it touches) Make sure you follow the contours of your vehicle carefully and ensure contact is made everywhere. Don't leave gaps where it doesn't touch. Material Quality: The quality of SilasPro 5mm Sound Deadening Material is excellent. It is thick and dense, which is key for absorbing sound, resonations, and vibrations. Despite its thickness (5mm), it's surprisingly lightweight, so it doesn't add much weight to the vehicle. Value: Excellent value for money. It performs on par with, if not better than, many more expensive brands in the market. Final Thoughts: Excellent product for anyone looking to improve the sound deadening of their vehicle. Its installation has made a noticeable difference, creating a quieter and more enjoyable ride.

I’ve used three different companies so far and have not been impressed until I bought from Silus. Very thick and sticks very well. It also has a great degree of flex which is great if you need to stretch it a bit for fitting. I’ve noticed a huge difference and don’t need to turn the radio up near as loud to drown out driving noise coming into the cabin.

First time using a sound deadening product like this it was hard to tell how much it helped. But it was easy to apply and seemed to hold up in my jeep wrangler.

Went in pretty easy because it cuts easy. Basic peel n stick. I’m sure it has thermal properties so it all helps. I also installed it inside the cap. Just to keep the condensation minimized.
