41 00... Position Of Shaped Parts For Cavity Bulkhead

WARNING: This page is about a different variant/trim than selected.

Cavity sealing is carried out in specific body areas in order to reduce internal noise and to reduce condensate. To do this, shaped parts are inserted in the cavities. These shaped parts adapt themselves optimally due to heating of the body to approx. 180 °C by expansion to the shape of the cavities.

Because it is not possible to heat the body to this extent for a body repair, a different procedure  See 4100... INSTALLING CAVITY SEALING (EXPANDED) , 4100... INSTALLING CAVITY SEALING (NOT EXPANDED)  or 4100... INSTALLING A CAVITY SEALING WITH 2-COMPONENT PU CAVITY FOAM  has been specified for this situation.
