Antivibration material Comfortmat Cobra

Comfortmat Cobra is one of the most popular anti-vibration materials for soundproofing cars, campervans, and RVs. Thanks to its modern butyl compound, it excellently dampens vibrations, adheres firmly to the sheet metal, and maintains a low weight. It is ideal as the first layer of sound insulation, followed by thermal or acoustic insulation.

An MLF value of 0.40 confirms that Cobra is among the most effective materials of its thickness. Compared to standard 3mm anti-vibration materials, it offers similar performance but without unnecessary added weight. This is appreciated by anyone building a campervan who is concerned not only with comfort but also with the final weight of the build.

Comfortmat Cobra is applied directly to the bodywork sheet metal, where it reduces resonance, strengthens individual body parts, and creates a solid foundation for further thermal or acoustic insulation.

To achieve maximum effectiveness, we recommend thoroughly rolling the material with a pressure roller after application. The butyl layer must adhere perfectly to the sheet metal – proper application is crucial for the resulting vibration damping.

Why choose Comfortmat Cobra?

• High vibration damping efficiency (MLF 0.40).
• Efficiency comparable to standard 3mm materials with lower weight.
• Modern butyl compound with excellent adhesion to metal.
• Strong aluminum foil with a thickness of 120 µm.
• Matte surface with a snakeskin texture for better adhesion of the next insulation layer.
• Resistance to water, moisture, and oils.
• Helps protect the bodywork from corrosion.
• Reliable properties in both summer and winter conditions.
• Easy installation without the need for heating.

Where is Comfortmat Cobra suitable?

Thanks to its universal thickness, Cobra is suitable for almost the entire van. It is most commonly used on:

• doors,
• side panels,
• roof,
• floor,
• wheel arches,
• boot space.

    Tip from Pimp Your Van: If I had to recommend one anti-vibration material for most builds, it would be Cobra. It works great on doors, side panels, and the roof. While the floor and wheel arches generate the most vibrations, I would definitely not underestimate other parts of the van. Vibrations are not transmitted only through one spot but spread throughout the entire bodywork. The better the doors or side panels are soundproofed, the quieter the whole car feels when driving.
