Abstract
A laminated barrier is provided that can be easily attached to the frame of a vehicle door. The barrier reduces the passage of water, dust and sound into and through the vehicle door. The barrier is generally flat and includes a channel formed therein that aids in locating a bead of adhesive material, aligned with, but located on an opposite side of the barrier from the channel. The bead of adhesive material bonds the barrier to the door frame of the vehicle. The channel acts as a witness line and can be formed as part of an overall thermoforming step, or more simply by using a single heated die element during a step when the barrier is trimmed.
