How to insulate an electric car

Insulation for electric cars
Electric cars are obviously much more quieter than cars with combustion engines. Because an electric car does not have a noisy engine some noises can become much more audible, such as airflow, tyres touching the road surface and vibrations from the bodywork. This gives us other acoustic challenges. This how you can reduce noise in electric vehicles.

Insulate road noise
Noise from tyres touching the roads surface can cause that tiring monotonous noise. This noise enters the vehicle by its wheel arches, floor and boot. The solution to this problem is relatively easy, insulate the arches and the floor with Vibraflex Extreme damping sheets. These anti-drumming and damping sheets isolates vibrations in these parts of the car and reduces driving noises. With the Isomat FM, soundproofing insulation floor mat, you can finish the Vibraflex and insulate your electric car even more.

Isolate electric motor noise
Electric motors can produces a high frequent noise that penetrates the cabin. You can avoid or reduce this noise from entering the cabin by applying sound absorbing materials in the engine bay. A product to absorb this noise is Acousticcell. Keep in mind that this product should only be applied in dry and clean aeras, because it has no protective top layer. Apply this product to the bonnet and side panels in the engine bay.

Insulation for the roof
In some cars the air flow over the roof and bodywork can produce whooshing like noise. This has to do with the shape of the roof. A few pieces of Vibraflex UF 30 can solve this. Apply a few sheets of Vibraflex on the flat surfaces under the roof liner against the sheet metal of the roof to insulate this noise.
