Top quality
Model: SLH20025
This Siless Hybrid 3-in-1 sound deadening mat is easy to work with and feels high-quality. The butyl material is thick and pliable, making it simple to cut and fit into doors, floors, or panels. After installation, road noise and vibrations are noticeably reduced, and it also seems to improve the overall cabin feel. No bad smell. At 25 sq ft per roll, it’s a good value for anyone looking to dampen noise and improve car acoustics. Overall, a solid, effective option for automotive soundproofing. Used on a Fiesta ST.

Made a big improvement in cabin noise—highly recommend
Model: SLH20025
Siless Hybrid made a huge difference in reducing noise in the floor of my truck cabin. In some areas, there was basically just bare sheet metal between the inside and outside, so adding this really helped the truck feel more solid and noticeably quieter on the road. I used Kilmat on the doors, and honestly I wish I had used Siless Hybrid there too, but it was too late by the time I realized the difference. This material is very sticky, easy to cut, and simple to apply, which made the install pretty smooth. Just a heads-up: the tacky side gets messy and will bond to clothing really easily, so be careful during installation. Overall, I’d definitely buy it again—great product with real results.

I wish I had Siless 20 years ago!!!
Model: SLH20025, Model: SLH20025
I have installed all kinds of insulation in vehicles over many years. I only needed to purchase 2 boxes to complete the entire interior siding of my 2025 chevy express, what a great value! I wanted to insulate my locksmith van for sound and heat. The sound reduction virtually eliminated the road noise. These panels also look amazing. It got up to 110F in the sun with the doors closed. After adding Siless insulation the temperature maxed out at 97F. That is a massive difference. Plus, I didn't even finish with the roof before testing. Siless Hybrid 3in1 was extremely easy to cut and adhere onto metal panels. I'm impressed with the quality of the individual panels and the adhesive is not toxic smelling compared to some others. My favorite thing about these panels is you can actually take them off and readjust them before they finally stick and they do not leave any black residue behind when you pull them up to adjust them. All I needed was a heat gun, knife and a roller to complete this job. The size of each panel is perfect, you can handle them with ease. I probably won't need your product again for a while, but when I do I will definitely be back.

Works well and is easy to install.
Model: SLH20025, Model: SLH20025
I was sound and heat insulating a generator bay in my class A RV so I did three tests before and during material application: I did a sound level test to see how effective the material was for my application, a "stickiness" test, and a flammability test. This was indoors on a dry 78°F day. From beginning to end, the entire process, including testing, took 5 hours to install 25 sqft or material in a very complex area. One hour for cleaning, 3 hours for installation, and 1 hour for test setup and testing. Using a sound meter, I took before and after readings and determined that I reduced the sound level by 2.2 db (40% energy decrease) with a noticeable decrease in sound and frequency. The generator bay is located under the master bedroom in the aft portion of the coach. The sound went from a rattling, vibrating generator noise to a more tolerable low level rumble. The material was easy to apply. I did some testing prior to application and determined that surface preparation is key. I cleaned my painted metal surface and then degreased with acetone and the material stuck well. Be careful and purposeful when you apply the material because once it was stuck to the metal, it was quite difficult to remove or reposition. Since it was going to be installed into a gasoline powered generator bay located under our sleeping quarters, I did some flame testing to determine the level of risk. Although not highly flammable after installation, my testing revealed that the PE used will catch on fire under certain circumstances. In order to reduce the risk, I used aluminized duct tape to ensure that all the edges were sealed and the PE was not exposed to direct flame in the event of a fire. I also decided to install an automatic fire extinguisher as an added precaution. In all fairness there should be one installed in the generator bay anyway. All in all, I am very satisfied with the product and the results. I have recommended this product to my other RV owner friends.
