Sound Proofing / Insulation: Description and Operation
Sound Insulation
Besides the sound insulation matting fitted in the body, there is also a special foam insulating material used under the rear door panes, in the luggage
compartment, in front of the rear wheel housing and in the C-pillar.
The foam insulating material is initially compressed to form a flat panel and shaped for the space where it will be fitted. In production, it is inserted in
the intended space and subsequently swells up into foam during the surface treatment process at about 180 degrees C.
