Overview
SoundSkins SSK-SSPRO-1 Car Sound Deadening Material is a 180mil (4.5mm) triple-layer insulation mat designed for automotive soundproofing and insulation applications. Constructed from pure rubber butyl bonded to a metal aluminum foil layer and closed-cell acoustic foam, this material is engineered to reduce vibrations, insulate heat, and minimize resonance within vehicle cabins. It is available in an 11 square foot coverage configuration and is intended for use across areas such as doors, floorboards, trunks, and other metal panels.
This solution combines vibration dampening and thermal insulation in a single layered format. The triple-layer build integrates rubber butyl, aluminum foil, and acoustic foam to address unwanted noise and panel resonance while also functioning as an additional insulation layer.
For detailed product specifications and availability, see the official product listing.
Construction and Material Composition
The material features a triple-layer design consisting of pure rubber butyl, a robust aluminum foil layer, and closed-cell acoustic foam. This configuration combines durability with sound deadening and insulation performance. The butyl layer functions as the primary vibration-dampening component, while the aluminum foil contributes structural reinforcement. The closed-cell acoustic foam layer supports additional sound absorption and insulation characteristics.
With a stated thickness of 4.5 millimeters (180 mils), the mat provides substantial coverage for noise and vibration treatment. The adhesive system uses a pressure-sensitive rubber butyl backing designed for peel-and-stick installation without additional glues or sprays.
Noise and Vibration Reduction
At 180 mils thick, the material is described as excelling in noise and vibration reduction. Reports indicate up to a 50 percent reduction in unwanted noise and vibrations. The triple-layer configuration is identified as the structural basis for its sound-deadening capability.
In top reviews, commonly repeated characteristics include effective noise reduction, improved cabin quietness, elimination of rattles, and reduced panel resonance. Customers frequently mention stronger door solidity and reduced road noise after installation.
Additional technical details can be reviewed on the product specification page.
Thermal Insulation and R-Value
Beyond vibration control, this material provides thermal insulation. It functions as a barrier between the vehicle interior and external temperature conditions. The stated R-value is 3.12 per inch, reflecting its thermal resistance. The product description notes that it helps regulate cabin temperature by minimizing heat transfer.
The mat is described as waterproof, heatproof, and flame-resistant. It withstands temperatures ranging from -40°F to 356°F and complies with Federal Motor Vehicle Safety Standard 302, indicating self-extinguishing properties.
Installation and Application
The material uses a pressure-sensitive adhesive backing that allows application directly to cleaned metal surfaces. Installation guidance indicates that surfaces should be free of debris, waxy oils, or rust prior to application. Cleaning with denatured alcohol is recommended to ensure proper adhesion.
It is intended for use on metal areas of vehicles including doors, floor panels, trunk areas, and other resonance-prone surfaces. Reviews commonly reference ease of cutting and application, strong adhesion, and effective conformity to contours and irregular surfaces.
Installation guidance and technical details are available through the manufacturer product page.
Coverage and Dimensions
The 11 square foot configuration provides coverage for targeted panel treatment. Product dimensions are listed as 79 inches in length by 19 inches in width. The item thickness is specified as 4.5 millimeters. Additional coverage options are available within the same product line in larger square footage formats.
Material classification identifies rubber as the base material, and the product is categorized for automotive soundproofing and insulation use.
