SGM makes a variety of automotive sound insulation products, and one of its most referenced offerings is a black 80 mil thick butyl mat designed for both noise reduction and vibration control. This material features a self-adhesive backing and includes a foil heat shield layer, offering a dual benefit of thermal insulation and acoustic dampening. Designed for installation inside vehicles, it aims to minimize ambient road noise and reduce metal panel resonance through full or partial surface coverage.

Material Composition and Build
This solution is composed of a pliable butyl mastic base layered with aluminum foil. The nominal thickness is 80 mil, equivalent to 2 millimeters, and it is packaged to cover 36 square feet. Each sheet measures approximately 15.7 by 9.8 inches, and the set includes 34 sheets. The foil component functions as a radiant barrier and provides added durability, while the butyl base is engineered to adhere effectively to both metal and plastic surfaces without cracking or becoming brittle under temperature extremes.
Installation involves cutting the material to size, removing the release liner, and applying it to clean, dry surfaces. A roller is typically used to press the material into place and eliminate air bubbles, ensuring proper contact. Recommended installation zones include floors, doors, firewalls, roofs, wheel wells, trunks, trunk lids, and hoods.
Performance Characteristics
This product is optimized for interior automotive environments where panel vibration and external noise are common challenges. Users have noted benefits when applying the material to subwoofer enclosures, trunk areas, and metal surfaces that tend to rattle or transmit road noise. Once applied, the material is designed to stay in place, even through thermal cycling and exposure to high cabin temperatures. Operating temperatures range from -49°F to 212°F, allowing for reliable performance across seasonal shifts.
While specific decibel reduction figures are not included in the source material, the construction and design suggest that consistent coverage in key vehicle zones may support an overall quieter ride. The foil-backed butyl structure offers both mass-loading and constrained-layer damping effects, which are widely accepted principles in automotive acoustics.
Application Scenarios
Practical applications vary based on vehicle type and soundproofing goals. For compact and mid-size cars, full coverage of floor pans, doors, and trunk interiors can be achieved using a single 36 square foot package. For larger vehicles, multiple packages may be required to cover extended surface areas. This material is also used by some users in non-automotive scenarios, such as reinforcing metal cabinets or speaker enclosures to reduce unwanted ringing or vibrations.
The ease of application is a notable factor, especially for users with minimal experience in DIY vehicle soundproofing. The grid pattern on the surface aids in cutting to precise dimensions, and the material’s weight allows it to conform to curves and contours without requiring excessive force. Several users report improved results when the product is warmed prior to installation, enhancing adhesion and flexibility during placement.
Pros and Cons
Pros
- Thick 80 mil butyl layer combined with foil for thermal and acoustic performance
- Adheres to both metal and plastic surfaces
- Effective temperature range from -49°F to 212°F
- Easy to cut and apply with included grid pattern
- Applicable to a wide range of vehicle areas
Cons
- Paper backing may tear during removal if not handled carefully
- No laboratory-certified acoustic reduction values provided
- May require heating for optimal adhesion on complex surfaces
Additional Considerations
For those seeking a durable and adaptable noise control option, this material offers a balance of user-friendly application and functional coverage. It can be integrated into larger vehicle soundproofing projects or used selectively to address specific trouble spots.

Users interested in improving cabin acoustics, reducing heat transfer, or eliminating panel vibration may find value in reviewing installation scenarios or application tips for this automotive insulation material. Whether applied to the floor or overhead surfaces, the black 80 mil deadening sheets allow for targeted treatment without the need for adhesives or specialized equipment. For broader coverage or non-standard applications, additional quantities of the same soundproofing solution may be necessary.
