Product Information
Full details
The Design Engineering Boom Mat Acoustic Tiles are an ideal solution for automotive enthusiasts and DIYers looking to improve cabin acoustics and reduce road noise. These tiles provide a high-performance dual-layer approach to sound dampening by combining a dense butyl barrier with a felt liner for simultaneous vibration and noise absorption. While they are highly effective at quieting vehicle interiors, the trim-to-fit nature of the panels requires careful planning and precision cutting to ensure a seamless installation on irregular surfaces.

FAQs
Can these tiles be used inside the engine bay?
These tiles are designed for interior use. While they are heat-resistant, they are not intended for direct exposure to high-heat engine components or external weather conditions.
How many tiles do I need for my doors?
Coverage depends on your vehicle size, but typically one tile covers the majority of a standard-sized passenger car door panel.
Does this replace traditional sound insulation padding?
Yes, it acts as a dual-purpose upgrade, replacing the need for separate vibration dampeners and sound-absorbing foam.
Is the felt material water-resistant?
The felt is designed to absorb airborne sound and is not waterproof. Avoid installing it in areas prone to pooling water or excessive moisture.
Can I paint over the felt surface?
No, painting the felt surface will fill the acoustic pores and significantly reduce its ability to absorb sound.
Does it matter which side faces the metal?
Yes, the butyl side must always be applied against the metal surface to ensure proper vibration dampening and adhesion.
Troubleshooting
Tile failing to adhere to the surface
Ensure the surface was cleaned with an alcohol-based degreaser. If the surface is cold, warm both the metal and the adhesive side of the tile slightly with a heat gun before application.
Difficulty cutting through the material
Use a fresh, sharp utility knife blade. Replace the blade frequently as the dense butyl material can dull edges quickly.
Air bubbles trapped under the tile
Use a seam roller or a rounded tool to press the tile from the center outward to force air toward the edges.
Pros and Cons
Pros
- Targets both vibration and airborne noise simultaneously
- Easy-to-use self-adhesive backing
- Provides a finished, high-quality look in visible areas
- Effective at reducing road and engine drone
- Durable, heat-resistant construction
Cons
- Requires precise measuring and cutting for complex areas
- Adds significant mass if used excessively on light panels
- Limited coverage per 2-pack for large vehicle interiors
Setup, Compatibility & Care
To install, first ensure the application surface is thoroughly cleaned with a degreasing agent to remove dust, oil, or rust. Use a sharp utility knife or heavy-duty scissors to cut the tiles to the desired size. Peel off the protective backing paper and press the tile firmly onto the surface, ensuring there are no air bubbles trapped beneath the material. A roller can be used to ensure total contact with the substrate. The tiles are compatible with standard steel, aluminum, and composite automotive panels. For care, simply wipe the felt side with a soft brush or vacuum to remove dust and debris as needed; do not saturate the felt with liquids or cleaning chemicals.
