Added insulation

I've been planning to add some insulation to the doors of my C-Zero. Insulation for the cold winter and also some sound dampening to reduce noise. Today I finally got it done. All four doors got some 1 cm thick foam with a sticky side and a side with aluminium foil.

Driver side front door before and after.

Passenger side rear door. Not as pretty, since I used leftover pieces.

Same door. Now you can see the foil in the unused speaker opening instead of cold steel.

On a quick test drive I noticed two things. The sound of the electric motor was more audible than before. I guess when you reduce other noises you start hearing others. I also noticed that the bass frequencies sounded louder on the car stereo. To be expected, since adding the insulation makes the doors perform better as speaker enclosures.

I'm also planning to add some anti-stone chip shield behind the front wheels. There doesn't seem to be much to speak of. It could also make the car quieter. At least concerning noises made by flying stones, if nothing else.

  1. Could you give some more details about this? Like, procedures for removing/replacing the covers? The exact insulating material? Thanks.

    1. Check out this video on how to remove the panels:

      The insulation material I used is the same type as this (in Finnish, but it has a picture):
