Genuine BMW Door Panel Insulation Vapor Barrier

Genuine BMW door panel insulation, also called a door vapor barrier, door sound insulation or door panel insulator, is the factory-style sheet that sits between the inner door structure and the interior door trim panel. It seals the openings in the door from the cabin. It also helps cut road noise.

Key Features:

• Original equipment BMW part, made to the same standard as the insulation installed at the factory
• Seals the door's service openings from the passenger compartment
• Helps reduce road noise and keep moisture and drafts out of the cabin
• Sits behind the door trim panel, so it stays out of sight
• A common replacement item after window regulator, speaker or latch service, because the barrier can tear or lose its seal when the door panel is removed

Replacing a damaged or missing vapor barrier restores the door's original sealing and sound-damping performance. Use the specific part number for the correct door position when you order.
