Purpose and body fitment

The presented glass has been designed specifically as a component for the rear left glazed area of the Audi A4 B9 generation. It is responsible for proper interior illumination, side visibility, and maintaining the stylistic lines of the body. The construction is adapted to the factory door profile, which translates into stable seating in the guides and correct interaction with the seals.

Thanks to its precise shape and appropriately selected glass thickness, the window works with standard mounting components, reducing the risk of stress and leaks. This is particularly important in body and paint repairs, where maintaining factory reference points is crucial.

Technical characteristics of AS2 glass

The AS2 marking indicates the type of glass used in vehicle side windows, meeting requirements regarding light transmission and user safety. This type of glass is tempered, which reduces the risk of large, sharp shards in the event of damage. This is significant both for passenger protection and for safety during removal and installation.

The optical parameters of the glass are selected so as not to distort the image and to ensure comfortable visibility in the mirrors and during maneuvers. At the same time, the glass works with factory seals and guides, which helps maintain an appropriate level of acoustic insulation and reduce wind noise.

Benefits of using original used glass

Choosing an original Audi side window in used condition is a reasonable compromise between repair costs and maintaining the vehicle's factory parameters. This type of component ensures:

• factory fitment to the door and body structure,
• compatibility with standard window lifting mechanisms,
• maintaining a consistent appearance with the other windows in the vehicle.

A used component allows for reduced service costs while maintaining the proper glass quality and compatibility with the body. This solution is particularly beneficial for post-collision repairs when it is necessary to replace several glazed elements.

Safety, OEM quality, and installation

Original windows from the Car windows category are designed to meet rigorous safety and durability standards. The proper glass thickness, appropriate tempering process, and fitment to the door frame affect the stability of the entire side structure of the vehicle. With proper installation, the seal is maintained, as well as the correct operation of the window lifting and lowering mechanism.
