For vehicle owners seeking a combined solution for noise reduction and heat management, this coating delivers a dual-action performance. Designed for both acoustic dampening and thermal insulation, it is applied as a spray-on or roll-on material suitable for a range of automotive surfaces. Once cured, the material forms a flexible membrane that helps reduce interior temperatures and suppress sound vibrations caused by road noise, mechanical resonance, and engine operation.

Thermal and Acoustic Properties
The material integrates ceramic microspheres within a water-based acrylic compound. This structure allows it to reflect and disperse heat effectively while dampening airborne and structural noise. Its functional composition enables it to act as both a thermal barrier and sound reducer, helping maintain a quieter and more temperature-stable vehicle interior.
This solution adheres to surfaces such as metal, fiberglass, plastic, and more, offering users the flexibility to apply it across firewalls, floor pans, trunk spaces, and wheel wells. It can be applied in multiple layers, allowing tailored thickness depending on the thermal or acoustic demands of the installation area. For optimal performance, proper surface cleaning and preparation are recommended before application.
Ease of Application
This product is supplied in a 1-gallon container and is compatible with spray, brush, or roll-on techniques. It dries to a black matte finish and is classified as non-flammable and non-toxic when dry. Coverage for one gallon averages approximately 75 square feet, depending on the surface texture and the number of coats applied. Its low-odor and water-based formula makes it a user-friendly option for those completing projects in enclosed or semi-enclosed spaces.
Because it does not require any adhesive or mat layering, the coating simplifies installation for users aiming to streamline their thermal and soundproofing upgrades. For vehicle customization projects, this makes it especially practical in restoring comfort to aging insulation systems or improving baseline factory acoustics.
Performance Considerations
Laboratory testing and user evaluations indicate consistent reductions in ambient cabin noise and noticeable temperature control in treated areas. The ceramic beads within the compound contribute to its reflective thermal behavior, while the cured acrylic membrane minimizes airborne noise transmission. Applications in underbody areas and door cavities show particular benefit in reducing high-frequency vibrations and heat soak from engine compartments and exhaust systems.
Durability is also an advantage. Once fully cured, the coating exhibits resistance to cracking, flaking, and peeling under typical automotive conditions. It can handle sustained exposure to temperatures up to 375°F, making it well-suited for parts of the vehicle exposed to elevated thermal loads. This resistance extends its suitability to off-road or high-performance applications where thermal and acoustic stress is higher than average.
Material Composition and Safety
Formulated as a water-based acrylic compound, this coating is designed with user and environmental safety in mind. It is categorized as non-hazardous under normal handling and is compliant with VOC safety standards. Its formulation does not include asphalt or other petroleum-based materials, reducing long-term off-gassing and improving environmental compatibility.
The lack of flammability after curing also adds a margin of safety in enclosed environments such as engine bays or behind dashboard panels. When applied according to the manufacturer’s guidelines, it poses minimal risk during installation and long-term use. These safety characteristics, combined with its effective performance, make it a practical choice for a range of automotive sound and heat insulation needs.
