Introduction
When comparing automotive sound deadening materials, two widely available options stand out for different reasons: Dynamat’s SuperLite Tri-Pack and ASLONG’s 80 mil Mat. Both offer butyl-based damping solutions designed to reduce vibration and road noise in vehicle interiors, but they differ significantly in thickness, coverage, and application focus. This comparison is designed to help clarify those differences using only verified information from each product’s source documentation and our detailed individual reviews.
How This Comparison Was Built
This evaluation is based entirely on published manufacturer materials and corroborated technical content from the official product sources. No claims beyond those found in the original product documentation or previously verified content are included. To dive deeper into each product’s standalone details, see the Dynamat SuperLite review and the ASLONG 80 mil review.
Key Decision Factors Identified From the Source Content
Based on available source data, the most relevant comparison factors include:
- Total coverage area provided per pack
- Stated installation zones and flexibility
- Use case emphasis (partial vs full coverage)
- Temperature range suitability
Dynamat 10612 18 x 32 Self Adhesive Sound Deadener Superlite Tri Pack Set of 3 Made in USA
The Dynamat SuperLite Tri-Pack offers a compact, lightweight option specifically intended for localized sound and vibration damping in vehicle interiors. With a total coverage area of 12 square feet, each of the three 18 x 32 inch sheets is designed for spot applications—ideal for doors, roofs, and trunk panels where weight and trim reassembly are critical concerns. Its thin profile, about 0.04 inches thick, makes it suitable for installations where space constraints matter. You can explore more about the product through the official Dynamat listing.
ASLONG 80 mil 26.9 sqft Car Sound Deadening Mat Butyl Automotive Sound Deadener Audio Noise Insulation and Dampening Material
ASLONG’s 80 mil sound deadening mat is designed for broader surface coverage, offering 26.9 square feet across 25 sheets. Each sheet is approximately 9.8 by 15.7 inches and features an 80 mil (2 mm) thickness for heavier damping in doors, trunks, floors, and hoods. Its aluminum foil layer adds structural integrity and supports installation in higher-temperature areas like engine hoods. To explore the material details, visit the ASLONG product page.
Head-to-Head Comparison: What the Evidence Shows
Side-by-side, the Dynamat and ASLONG products differ primarily in scope, thickness, and intended installation approach. Dynamat is focused on lightweight, partial coverage with its thinner 0.04-inch profile and 12 square feet of material. This makes it suitable for noise or vibration hotspots where maintaining panel clearance is important. ASLONG, by contrast, provides more than double the coverage and thickness, making it a candidate for broader treatment needs. ASLONG’s stated temperature range of -49°F to 212°F offers an explicit environmental operating specification not matched by Dynamat’s documentation, though both reference vehicle-interior suitability.
At-a-Glance Comparison Table
| Attribute | Dynamat SuperLite | ASLONG 80 mil |
|---|---|---|
| Total Coverage Area | 12 sq ft | 26.9 sq ft |
| Thickness | ~0.04 inches (~40 mil) | 0.08 inches (80 mil) |
| Sheet Count & Size | 3 sheets (18 x 32 in) | 25 sheets (9.8 x 15.7 in) |
| Intended Use | Localized applications | Partial or full-area coverage |
| Temperature Range | Not numerically specified | -49°F to 212°F |
| Adhesive Type | Pressure-sensitive butyl | Pressure-sensitive butyl |
| Aluminum Layer | Yes | Yes |
Which One May Be the Better Fit for Different Situations
For installations focused on specific noise points or where maintaining interior panel tolerances is a concern, the Dynamat SuperLite’s thinner profile and targeted design may offer a better fit. Its lightweight construction suits partial treatments. On the other hand, users seeking more extensive coverage or higher material mass for broader vibration and noise control may find the ASLONG 80 mil mat better suited, especially in areas like trunks and floorboards where space and weight are less constrained.
Frequently Asked Questions
Do either of these products include lab-tested noise reduction data?
No. Neither the Dynamat SuperLite nor the ASLONG 80 mil mat provides certified lab-based sound reduction figures in the available source materials.
Can these products be used for thermal insulation?
While both products include an aluminum backing and are installed in areas exposed to temperature shifts, only ASLONG’s documentation specifies a temperature range. Neither product is marketed primarily for thermal insulation.
Are additional tools or adhesives required for installation?
No. Both products feature pressure-sensitive backing and are designed for peel-and-stick application on cleaned metal surfaces.
