Vibration isolation Combi BMF

It is bitumen and mastic combined vibro insulation. It is a multi-layer material consisting of vibration dampening materials: aluminum foil, elastomer and bitumen mixture and mastic, which also acts as an adhesive during installation. The mounting side is covered with protective paper.

• Insulation thickness: 4.0 mm
• Foil thickness: 100 µm
• Mechanical loss factor: 0.49
• Weight: 6.0 kg/m2
• Sheet size: 800x500 mm

This vibration insulation has all the best properties of bituminous and mastic vibration dampening materials - structural strength, ease of installation, high mechanical loss coefficient, adhesiveness and reliability of fastening. Also, this tool protects the body from corrosion.

The mechanical loss coefficient of the material is 0.49. What is this?

The body of the car resonates when driving or simply when the engine is running - it emits vibrations. Ideally, the body surface materials should absorb the vibration and convert it into thermal energy. The mechanical loss coefficient, MNK, shows how much vibrational energy is exchanged for heat. Driving comfort depends on it. If MNK is 1 - this is the maximum result, all the vibrational energy is replaced by heat. If MNK <1, the sound and vibration absorption properties of the material are worse. When choosing an insulating material, you should pay attention to this number. A higher number is better.

Why should you try soundproofing materials?

Extraneous sounds and vibrations are felt while driving the car. This noise is not only unpleasant, but can also cause serious health problems. Sound insulation materials help to solve this. They ensure additional comfort during the trip. Less vibration is felt while driving, there are no squeaks caused by parts touching each other, no extraneous noise from the street or the engine compartment. Talking in the car becomes easier, less tiring, nothing distracts attention while driving. Since these materials also act as a heat insulator, it is easier to start the engine in winter, and the interior freezes less. Almost the entire body of the car can be lined with insulating materials, thus ensuring the greatest effect.

Recommended: The sides of the car body, the bottom of the body and trunk, the engine-interior partition from the interior side.
