Introduction
When selecting a sound deadening solution for automotive use, options like the ASLONG 80 mil Butyl Sound Deadening Mat and the SGM Gold Exclusive 80 mil Butyl Mat often surface due to their similar material composition and application method. This comparison examines source-confirmed specifications to help readers identify where the two differ in measurable ways. Both products aim to reduce noise and vibration inside vehicle cabins, but their documented attributes show clear distinctions that may guide installation or coverage decisions.
How This Comparison Was Built
This side-by-side analysis was developed using only verified manufacturer-provided information and close-to-source product specifications. Each product’s features were cross-referenced and classified as corroborated, weakly supported, or conflicting. No assumptions or inferred performance claims were used. For complete product breakdowns, see the full individual reviews: ASLONG review and SGM Gold Exclusive review.
Key Decision Factors Identified From the Source Content
Documented differences between the ASLONG and SGM Gold Exclusive mats center on total coverage area, temperature resistance specifications, and documented environmental durability. Both use butyl rubber and foil-backed construction and offer peel-and-stick installation, but only ASLONG includes an explicitly stated operating temperature range. Conversely, only SGM Gold notes resistance to humidity and minor chemical exposure.
ASLONG 80 mil 26.9 sqft Car Sound Deadening Mat Butyl Automotive Sound Deadener Audio Noise Insulation and Dampening Material
The ASLONG butyl mat is a foil-backed sound deadening material designed for universal application in vehicle interiors. It is sold in a 25-sheet format, totaling 26.9 square feet of coverage. Its operational temperature range is documented from -49°F to 212°F, supporting installation in both hot and cold climates. It uses a peel-and-stick system and is suited for use in vehicle doors, floors, trunks, and hoods. For full product details and installation guidance, read the ASLONG product review.

SGM Gold Exclusive 80 mil Automotive Butyl Sound Deadening Mat – 36 sqft Self-Adhesive Sheet
The SGM Gold Exclusive mat features the same 80 mil thickness and foil-backed butyl construction as ASLONG but offers a greater total coverage area at 36 square feet. It emphasizes flexibility and installation ease across contoured metal surfaces. While it does not list a specific temperature range, the source content highlights resistance to heat, humidity, and mild chemicals. This makes it potentially suitable for environments where chemical exposure is a factor. To learn more, see the full SGM Gold Exclusive review or view the SGM Gold Exclusive product listing.
Head-to-Head Comparison: What the Evidence Shows
While both products share core materials and usage formats, certain distinctions are confirmed in their documentation. ASLONG provides a detailed temperature range, whereas SGM Gold Exclusive highlights environmental resistance properties. ASLONG comes in pre-cut sheets totaling 26.9 sqft, offering straightforward installation management. SGM Gold provides a larger 36 sqft coverage in a less-defined format, potentially offering more flexibility for larger installs, though its sheet breakdown is unspecified. Only ASLONG specifies placement behind speaker mounts to reduce resonance, though this is not independently validated.
At-a-Glance Comparison Table
| Attribute | ASLONG | SGM Gold Exclusive |
|---|---|---|
| Thickness | 80 mil | 80 mil |
| Coverage Area | 26.9 sq ft (25 pre-cut sheets) | 36 sq ft (sheet format unspecified) |
| Material | Butyl with foil backing | Butyl with foil backing |
| Temperature Range | -49°F to 212°F | Not specified |
| Environmental Resistance | Not specified | Resistant to humidity and mild chemicals |
| Installation Type | Peel-and-stick | Peel-and-stick |
Which One May Be the Better Fit for Different Situations
ASLONG may be more suitable when a specific temperature range is important or when pre-cut sheet format simplifies layout planning. It may also appeal to users applying material near speaker mounts, though this is not externally validated. SGM Gold Exclusive, with its larger coverage area and documented chemical and humidity resistance, may be a practical fit in environments where those conditions are present. Because the sheet configuration for SGM is not specified, it may require more cutting or trimming on-site.
Frequently Asked Questions
Are both mats suitable for DIY installation? Yes. Both mats use a self-adhesive butyl backing designed for direct application to metal surfaces without specialized tools.
Is there any lab-certified noise reduction data available? No. Neither product includes lab-based acoustic performance ratings or decibel reduction values in the source materials.
Can these mats be used under the hood? Yes. Both list roof and hood installation as viable, though only ASLONG confirms performance across a specific temperature range.
Closing Guidance
Both the ASLONG and SGM Gold Exclusive mats deliver butyl-based sound deadening in an 80 mil format with peel-and-stick convenience. Their key distinctions lie in documented coverage area, environmental specifications, and sheet layout. Users are encouraged to read the full ASLONG review or explore the SGM Gold Exclusive details to determine the best match for their installation context.
