Sound Proofing / Insulation: Service and Repair

ATTACHMENT OF SILENCERS




Silencers (petroleum-asphalt sheets) are attached to the upper surface of the floor and at the interior side of the dash panel in order to absorb vibrations and shut out exhaust gas heat. If these silencers are peeled.off in the course of replacement or repair of a welded panel, cut and attach replacement material (in the' shape shown in the figure).




1. Heat the "Silencer layer" (petroleum-asphalt sheet) with a blow drier to soften it.




2. Align the silencer layer in the position where it is to be installed, and then press it down with a roller or a block of wood so that it adheres well.

NOTE: An infrared lamp can also be used to heat both the silencer layer and the body panels (be sure to wear gloves).
