## Description

Sound Deadening is one of the most effective things you can do to your car to improve sound quality and eliminate road noise. SILESS was originally designed for the automotive industry and engineered for car soundproofing and sound dampening. By reducing or dampening sound vibration in the metal panels of your car, you can eliminate road noise. Whether you are trying to improve the quality of your car stereo or give your vehicle that “luxury car” feel, SILESS is the ideal material. Unlike some other companies, who use repurposed asphalt roofing materials, SILESS created industry approved Bmastic technologically advanced formulation that is lightweight, easy to cut, super sticky, and 20-30% more effective than any competitors on the market. 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. Installing together SILESS VIBRO and SILESS LINER - such as SILESS 157 mil and you’ve got a ride with even more noise-blocking outcome. 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: 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.
Review: Excellent adhesion and high-quality material thickness is great worked well too quiet the sound in side-by-side
