Second Skin introduces a specialized automotive solution built to target structural noise through vibration damping: a butyl rubber sound deadening mat available in an 8-sheet configuration covering 13.67 square feet. This material is engineered for application across a range of automotive surfaces, with a focus on addressing structure-borne vibration in doors, trunks, firewalls, floors, and other metallic components.

Material Construction and Composition
The product uses an elastomeric butyl rubber base bonded to an aluminum foil constraint layer. This constrained layer damping structure is designed to suppress mechanical vibrations that can cause audible noise within vehicle cabins. The foil layer, specified at 6.5 mils thick, adds dimensional stability and reinforces the mat’s ability to resist deformation under high thermal stress. Each sheet measures 12 inches by 20 inches and contributes to a total material thickness of 2 millimeters.
Performance Characteristics
Tested to function effectively at temperatures up to 450°F, this material offers both thermal and acoustic insulation properties. It is labeled as odorless and compliant with RoHS safety standards. The mat’s design allows it to act not only as a vibration damper but also as a supplementary thermal barrier when used in heat-prone areas such as under the hood or near the engine compartment.
Installation Process
This product utilizes a self-adhesive backing that enables peel-and-stick application without the need for additional adhesives or activation methods. Once the surface is properly cleaned and prepped, the mat can be trimmed and applied directly to the metal substrate. Due to the density and thickness of the material, it remains stable after application and conforms to curved and uneven surfaces commonly found in vehicle interiors.
Common Use Cases
These panels are frequently used in automotive restoration and audio system upgrades, particularly in vehicles where factory-installed noise control materials are insufficient. Applications span a variety of vehicle types including sedans, trucks, SUVs, RVs, and custom-built or modified vehicles. Their use extends to reducing noise in areas where engine or road vibration is transmitted through the body structure, which may include wheel wells, doors, and trunk compartments.
User Observations
Customer feedback highlights the material’s weight, adhesion, and ease of installation as standout traits. Many users apply the panels selectively—rather than fully lining surfaces—to achieve a high level of damping efficiency with less material usage. The product’s rigidity and thickness were also noted as suitable for targeting specific panel zones prone to resonance, especially in cargo areas and door cavities. Some reviewers also indicated successful application outside traditional automotive contexts, such as household fixtures or industrial panels.

This solution offers a technically straightforward method for reducing structure-borne automotive noise through targeted vibration damping. For those considering a dense, high-adhesion sound deadener with thermal tolerance, this butyl rubber sound deadening mat presents a durable option. Its compact sheet size and high-temperature rating make it adaptable for installations ranging from doors to engine bays. Users seeking to improve cabin acoustics without full vehicle coverage may find strategic application of this automotive sound deadening material an effective method of noise control. Those planning multi-phase treatments across doors, trunks, and floor panels can benefit from beginning with an 8-sheet sound deadener set to evaluate coverage efficiency. For targeted installations requiring high durability, this butyl rubber mat offers a practical balance between density and workability.
