Overview
The RUNSUNSPRI Car Sound Deadening 80 mil 9 sqft Sound Deadening Mat Sound Deading Material for Cars Butyl Automotive Sound Dampening is a rubber-based automotive insulation product designed for sound insulation in vehicles. It features an 80 mil thickened design and a three-layer composite structure of butyl rubber, aluminum foil, and high-adhesion backing. This material is intended to block road noise, tire noise, engine vibrations, and wind noise during driving.
This solution is positioned for use in key vehicle areas such as doors, roof, chassis, trunk, wheel arches, and engine hood, providing coverage across high-noise zones.
Key takeaways
- The material has 9 sqft coverage and is designed for sound insulation in vehicles.
- It features a three-layer composite structure of butyl rubber, aluminum foil, and high-adhesion backing.
- The 80 mil thickened design aids in damping sheet metal vibration.
- The aluminum foil layer reflects heat radiation and is described as blocking up to 98% of heat transfer.
- The sheets are flexible, easy to cut and bend, and include high-adhesion backing for installation.
What the product is designed to do
This automotive insulation material is designed to meet the noise insulation needs of key vehicle areas including doors, roof, chassis, trunk, wheel arches, and engine hood. It is described as suitable for various vehicle types including sedans, SUVs, and trucks.
The three-layer structure is specifically designed to block road noise, tire noise, engine vibrations, and wind noise during driving. The butyl rubber layer provides damping properties, while the aluminum foil layer reflects heat radiation. The listing states that the aluminum layer blocks up to 98% of heat transfer from the engine and external sources.
It is described as sound deadening material rather than full soundproofing material, and is intended to reduce resonance through metal surfaces.

Installation and placement notes
The material is described as flexible, easy to cut and bend, making it suitable for complex curves such as door arcs and chassis grooves. The installation process is described as clean, cut, paste, and press. The sheets include high-adhesion backing to support attachment to surfaces.
Reviews note that installation requires removing interior door panels when applying inside doors. The material is peel and stick, and users mention that it adheres strongly to surfaces and should not be allowed to stick to itself. Installation is noted to require temperatures above 50° Fahrenheit.
It is also described as thin enough to install under interior trim panels without interfering with panel fit.
Performance characteristics described in the listing
The 80 mil thickened design is described as aiding in damping sheet metal vibration. The aluminum foil layer is described as efficiently reflecting heat radiation and blocking up to 98% of heat transfer from engine and external sources.
The butyl rubber layer is described as absorbing and converting vibration energy, reducing secondary noise caused by vibrations. The material is also described as waterproof and capable of blocking sound and air transmission through holes and cutouts.
Use cases include blocking tire noise during daily commutes, reducing wind noise on long drives, and optimizing audio quality when upgrading sound systems.
Review patterns buyers commonly mention
Across reviews, buyers commonly mention that the sheets are easy to cut and easy to install. The adhesive is repeatedly described as very strong and highly sticky. Multiple reviews note reduced road noise and vibrations after installation.
Reviewers also reference the density of the material and describe it as heavy and dense. Several note that it is sound deadening material rather than full soundproofing, and that it is used as a base layer before adding additional soundproofing material.
