Some companies use technology and processes created over 10 years ago, and selling their products at a price 3 times higher than Siless. SILESS will install easily and stick to all and any interior surfaces, such as; floors, doors, roof, hood, trunk lid, quarter panels and will easily stick to a any other surface and will stay in place without any special preparation, and without any messy drippings and odor.

First layer of SILESS VIBRO provides 65% off road noise and vibrations and then second layer of SILESS LINER provides 35% coverage from excessive heat. Together, it is ULTIMATE SOLUTION for your sound dampening needs. Finally, SILESS today - the most advanced, industry approved, ultimate sound dampening material on the market.

Review: Best butyl out there. - If you want the money you're spending on equipment to pay off, you NEED to deaden sound! I've used every major brand and siless is my favorite to work with and the best value for your money, I'm not just adding weight, it's a thermal barrier and reduce outside noise. I turned a 10 year old, base model civic into what feels like a top tier Lexus . Does not offgas, no smell. Super easy to install. Make sure you get a set of rollers! They're required to achieve the advantages of this stuff, it MUST be adhered well and you don't want to tear the interior out twice.
Review: Siless Max - Awesome product, very easy to install and works really well!
