The X AUTOHAUX 394mil 10mm sound deadening mat introduces a dense, foil-backed insulation material tailored for reducing noise and heat transmission in confined vehicle spaces. With a foam thickness of 10mm and a single-sheet coverage of 2.16 square feet, this material is sized for small to mid-range applications in automotive or marine environments. Its primary design focus is dual-purpose: acoustic dampening and thermal reflection across interior surfaces such as hoods, fenders, or engine compartments.

Design and Construction
This solution incorporates an aluminum foil surface bonded to a closed-cell foam layer, offering a composite structure suited for multi-modal insulation. The foil face provides a barrier to radiant heat while the foam core contributes to airborne sound absorption. Dimensions measure approximately 19.69 inches by 15.75 inches per sheet, which allows ease of handling during installation and is suitable for targeting localized noise or thermal problem zones.
Backing the material is a self-adhesive layer, enabling direct application without requiring auxiliary fasteners or mechanical supports. The adhesive is designed for automotive and marine conditions, and each pad is resistant to moisture, which supports durability in high-humidity or semi-exposed settings. This makes the material particularly adaptable for use in boat engine covers or similar enclosures where condensation may be present.
Thermal Shielding Functionality
The aluminum layer serves to deflect external heat sources, particularly from engine components, exhaust paths, or sunlight exposure. When applied to internal body panels or under-hood surfaces, the material can reduce thermal transmission into the passenger cabin or storage compartments. This may contribute to improved thermal consistency during both hot and cold weather conditions and assist in optimizing HVAC performance. For those seeking a heat-reflective insulation mat for vehicle hoods, this configuration offers a simplified option with manageable form factor and weight.
Noise Dampening Application
With its 10mm thickness, the foam layer can aid in minimizing mid- to high-frequency noise generated by engine vibrations, road texture, or structural resonance. It is intended to reduce transmission of such noise into occupied spaces, creating a quieter environment within the vehicle or vessel. Application areas include doors, wheel arches, engine bays, and trunk interiors. Installers targeting sound deadening material for boat engine covers may find its size and moisture resistance useful for confined marine compartments.
While specific decibel reduction values are not provided in the manufacturer documentation, the foam density and bonding integrity suggest potential for moderate acoustic improvement in non-industrial applications. The ease of cutting and shaping also allows for customization around curved panels or irregular surfaces, increasing its utility for DIY soundproofing efforts.
Installation Considerations
The product is engineered for direct application using its integrated adhesive backing. Prior to mounting, surfaces should be cleaned and degreased to ensure firm adhesion. The manufacturer notes that pressing the material with a roller may improve the seal and reduce air gaps. Installers may also heat the mat lightly to enhance pliability around corners and tight fittings.
Because the material is not rated for exposure to direct heat sources such as exhaust pipes or mufflers, its placement should be restricted to insulated zones or shielded panels. Users interested in applying sound insulation under car hoods should evaluate clearance and avoid interference with airflow or wiring paths.
