Joints symmetrically opposite to those shown are also treated. Apply 3mm diameter beads to all joints shown. Leave
rocker drain points free of adhesive.
Expanding Foam Acoustic Seals
Expanding foam acoustic seals are used in various closed sections of the body to improve vehicle refinement. The seals
expand in the factory during the paint process, they expand up to eight times original size thus locking them into position.
The seals do several important jobs but there main function is to insulate the cabin from noise and vibration, particularly
road noise. they are located such that they prevent noise accentuation along a section and reflect air borne noise away
from the cabin.
A secondary function of the seals is that the internal sections are sealed from the infiltration of water, air, dust and gases.
Another advantage of the seals is that they marginally increase the overall stiffness of the body and its structural
performance in case of a crash.
The seals are manufactured from an expandible rubber, 'Betacore 4300'
