Anti-vibration material Comfortmat Viper

Comfortmat Viper is one of the most powerful anti-vibration materials for soundproofing cars, camper vans, and RVs. Thanks to its modern butyl compound, it effectively dampens vibrations, adheres firmly to sheet metal, and forms an ideal first layer of soundproofing, which is then followed by thermal or acoustic insulation.

With a thickness of 3 mm and an MLF of 0.49, it offers exceptionally high vibration damping efficiency while maintaining a favorable weight. It is an ideal choice for anyone looking for maximum performance without unnecessarily increasing the weight of the entire conversion.

Comfortmat Viper is applied directly to the car body's sheet metal, where it reduces resonances, strengthens individual parts of the car, and creates an ideal base 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 – correct application significantly affects the resulting vibration damping.

Why choose Comfortmat Viper?

• 3 mm thickness – high efficiency without unnecessary weight increase.
• Acoustic loss factor (MLF) of 0.49 for exceptionally effective vibration damping.
• Excellent performance-to-weight ratio.
• Modern butyl compound with high adhesion to metal.
• 120 µm thick aluminum foil for increased strength and stability.
• Matte surface with a snake skin texture for better adhesion of the next insulation layer.
• Resistance to water, moisture, and oils.
• Helps protect the bodywork from corrosion.
• Stable properties in both summer and winter conditions.
• Easy installation without the need for heating.

Where is Comfortmat Viper suitable?

Thanks to its 3 mm thickness and high efficiency, Viper is particularly suitable for body parts with higher vibration loads. It is most commonly used on:

• floor,
• wheel arches,
• outer and inner door panels,
• roof,
• boot floor,
• fenders,
• scuttle,
• center tunnel.

💡 Practical tip from Pimp Your Van: If you want to achieve a really high level of soundproofing, but at the same time don't want to add unnecessary kilograms, Viper is a great choice. I would most often use it on the floor, wheel arches or doors, where it can significantly reduce vibrations and calm the entire body. That's why it's also excellent for camper vans, where every kilogram matters.
