Rockville RockMat 50-25 is a high-performance sound and vibration dampening material designed to minimize road noise, reduce rattling, and improve the sound quality of your vehicle or audio system. At 2.5mm (100 MIL) thick, this kit provides 50 square feet of coverage in 20 pre-cut sheets, making installation simple and effective. By reducing sound leakage and unwanted vibrations, RockMat increases Sound Pressure Level (SPL), enhancing sound clarity and reducing distortion. It’s perfect for cars, trucks, boats, ATVs, UTVs, home studios, and home theaters—wherever noise reduction is needed.

Premium Butyl Rubber for Maximum Vibration Absorption

RockMat is made from 100% virgin butyl rubber, a material known for its exceptional sound-absorbing properties. Its dense composition absorbs vibration, reducing structural noise and eliminating rattles. Its high-tack adhesive backing ensures a firm hold and long-lasting performance, even in extreme conditions. Unlike some materials, butyl rubber remains flexible over time, preventing cracking or deterioration.

Aluminum Coating for Heat Resistance and Durability

The reinforced aluminum coating on RockMat adds an extra layer of protection and stability. 20% thicker than the first generation RockMat, this coating increases thermal resistance, helping to regulate heat and prevent material degradation. It also increases overall mass, further reducing sound transmission while ensuring the material can withstand high temperature environments.

Flat-Shipped for a Seamless Installation

Unlike rolled or folded materials, RockMat is shipped flat for a smoother application with no wrinkles or kinks. The 20" x 18" pre-cut sheets are easy to handle and apply, reducing installation time.

Smart Installation Indicator

The unique embossed pattern changes from hexagonal to flat when properly installed, ensuring maximum contact and adhesion for the best sound attenuation results.

All-Weather Durability

• Waterproof & Heat Resistant: Withstands moisture, salt water, extreme heat and cold.
• High Temperature Adhesive: Works in temperatures from -14°F to 320°F.
• Environmentally Friendly & Non-Toxic: Safe, odorless and free of harmful chemicals.

Performance That Makes a Difference
