Body System - General Information: Insulation

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

Insulation is used as a sound-deadener to reduce exterior road and powertrain noises from the interior of the vehicle. Mastic insulators are also used as insulation. Insulation is installed:

under the roof.
above and below the instrument panel.
at the cowl side panels.
over the front and rear floor pans.
inside the B-, C- and D-pillar sections.
on the wheel house/quarter panel.
behind the rear quarter trim panel.

Other forms of insulation include:

front tunnel stiffening pad.
dash panel stiffener.
rear wheelhouse mastic pads.

It has heat-bonded mastic deadeners for improved NVH characteristics.

It also has sound dampeners located inside the D-pillar and plug holes in the rear quarter inner.
