Vibration isolation BitAlum B2P

We recommend using: Sound insulation Noise Protection PROFI Vibrofiltr 2mm

It is a vibration damping material. The material is made of bitumen modified with elastomers with a layer of polyethylene film and a layer of assembly glue protected by non-stick paper. The polyethylene film protects against sticking to the adhesive roller during installation and ensures easy installation of the material.

• Thickness: 2.0 mm
• Mechanical loss factor: 0.12
• Weight: 2.7 kg/m2
• Adhesion to metal: 6 N/cm
• Sheet size: 800x500mm

When installing an additional layer of insulation, it is recommended to remove the protective polyethylene film from the insulation before carrying out further work.

The mechanical loss coefficient of the material is 0.12. 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, and no extraneous noise from the street or the engine compartment. It becomes easier to talk in the car, 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 bottom of the car's arches, body and trunk, engine - cabin partition from the cabin side.
