Siless introduces a butyl-based sound deadening solution designed to address common sources of automotive noise and vibration. With a thickness of 80 mil (2 mm) and a total coverage of 36 square feet, this material targets areas prone to structural resonance, such as vehicle doors, floors, and trunks. Its black finish and self-adhesive construction support straightforward installation across a range of metal surfaces.

Material Composition and Design
This sound insulation product is composed of a butyl rubber compound intended for both noise reduction and vibration dampening. The 2 mm thickness offers a balance between mass and flexibility, supporting coverage without significantly altering structural clearances. A foil outer layer is integrated for enhanced stability and surface durability during application.
The product does not require additional adhesives, as it features a peel-and-stick backing that adheres directly to treated surfaces. This design minimizes preparation time and simplifies installation, making it a practical option for individuals modifying automotive interiors without specialized tools.
Application Coverage and Use Cases
Covering 36 square feet, this material is positioned to serve medium-scale vehicle projects, such as treating all four doors or the entirety of a vehicle floor. Installers may also apply the mat selectively to target areas where road, engine, or mechanical noise commonly penetrates the cabin.
The combination of flexibility and self-adhesion allows this automotive sound deadening mat to conform to uneven surfaces and complex contours. Once applied, the material functions as a mechanical barrier, reducing vibrational energy transfer and airborne noise within treated sections.
Thermal and Acoustic Characteristics
While specific decibel reduction and R-value performance metrics are not provided, the presence of an aluminum foil surface contributes to additional thermal insulation. This characteristic may be beneficial in managing heat transfer through vehicle panels, particularly in high-exposure areas such as firewalls or floor pans.
In terms of acoustic behavior, the product is designed to function as a dampening layer, converting vibrational energy into low-level heat through internal friction. This mechanism reduces structural resonance, thereby limiting the transmission of ambient and mechanical noise into the vehicle cabin.
Installation Considerations
Due to its roll-based format and adhesive backing, the material is typically cut to shape and pressed into place using a roller or similar tool. Proper surface preparation—including cleaning and degreasing—is recommended to ensure reliable bonding. Once applied, the material is not intended to be repositioned, which underscores the importance of initial placement accuracy.
This vibration-dampening mat can be used as a standalone treatment or combined with other insulation materials to achieve layered soundproofing effects. Users focusing on comprehensive acoustic control may pair it with foam liners or thermal barriers for compound treatment goals.
Pros
- Self-adhesive butyl construction eliminates need for additional glue
- Foil layer provides added rigidity and thermal insulation
- 2 mm thickness supports effective vibration control
- 36 sqft coverage accommodates mid-size automotive projects
Cons
- No quantified sound or thermal performance data is provided
- Not repositionable after application
User Feedback Trends
Reviews indicate that the product is frequently selected for ease of use and flexibility during installation. Repeated themes include its ability to conform to varied surfaces and the lack of odor during application. The absence of detailed acoustic testing is noted, though many purchasers report a subjective improvement in cabin quietness following installation.
For those seeking a basic yet functional approach to treating automotive noise and vibration, this butyl sound insulation material offers an accessible entry point. Its size and composition make it suitable for targeted or whole-area treatments across most standard vehicle platforms.
