Design Engineering Boom Mat 12.5" x 24" 2mm sound deadening (Pack of 20) 🧰

This sound deadening mat from Design Engineering is built to reduce vibration and road noise in vehicles and equipment while being quick to apply thanks to its adhesive backing. The 12.5 by 24 inch sheets are practical for lining doors, floors, trunks, and panels, and the thin 2 mm profile helps control sound without taking up much space.

Key Points

The product arrives as a pack of 20 sheets of sound damping material, each measuring 12.5" x 24" with a thickness of 2 mm. The sheets combine a rubber-based viscoelastic polymer layer with a durable aluminum surface that resists wear. According to the manufacturer, surface preparation is minimal and the adhesive backing simplifies installation, which reduces time and effort compared with mechanical fasteners. Consider that while the aluminum surface offers durability, it may require trimming for complex curves or tight corners.

Technical Specifications

• Name: Design Engineering Boom Mat Sound Deadening Material
• Quantity: 20 sheets
• Sheet size: 12.5" x 24"
• Thickness: 2 mm
• Construction: rubber-based viscoelastic polymer with aluminum surface

Benefits

This mat helps lower cabin noise by damping panel vibrations and blocking airborne sounds that pass through thin metal surfaces. The combination of a polymer damping layer and an aluminum facing delivers both acoustic control and surface protection. Its low-profile 2 mm build is useful where space behind panels is limited, allowing improvements in comfort without interfering with trim fitment. Installation is faster for most DIYers because of the ready adhesive backing, and working in smaller sheets makes it easier to conform to irregular shapes.

Usage Recommendations

For best results, clean the application surface to remove grease, dirt, and loose paint before applying the mat. Warm the sheets slightly in cold environments to improve flexibility and adhesive tack during placement. Press firmly across the entire sheet after positioning to ensure full contact with the substrate and to minimize trapped air pockets. For curved or contoured areas, score and overlap small sections rather than forcing a single sheet to conform, which can help maintain adhesion and coverage. If additional mass is desired in specific zones, layering multiple sheets is possible but bear in mind the added weight and reduced clearance behind panels.

Note: Performance descriptions are based on the product construction and manufacturer guidance. This material reduces vibration and noise transmission from metal panels, but results will vary depending on vehicle type and installation coverage.
