Purpose and fitment for Mercedes W205

The offered rear window is dedicated to the saloon (sedan) body type of the Mercedes C-Class W205 generation. The glass construction is adapted to the factory roof and pillar profile, which translates into precise fitment with the bodywork, correct positioning in the frame, and system tightness after installation.

Its placement in the rear zone of the body means that the window works in conjunction with the trunk lid, interior upholstery, and factory seals, which facilitates installation and reduces the need for additional bodywork or upholstery modifications.

Technical characteristics of AS2 glass

The rear window is made of AS2 class glass, which means it meets rigorous safety and light transmission requirements for rear windows. This type of glass is tempered, resistant to typical operational loads, and designed to shatter into small, blunt fragments in the event of damage.

The AS2 glass parameters ensure the right balance between transparency and user comfort, supporting proper rear visibility and compatibility with the rearview mirror and driver assistance systems that utilize the field of view through the rear window.

Benefits of using an original rear window

Using an original rear window in a Mercedes W205 translates into a number of practical benefits:

• preservation of factory body geometry and proper fitment with seals,
• correct water drainage from the roof and rear window area thanks to matching original moldings,
• maintenance of the structural rigidity designed by the manufacturer in the rear part of the body,
• consistent visual appearance with the vehicle's other windows.

The component from the Car windows group is of key importance for passive safety, driving comfort, and interior acoustics, which is why choosing original glazing is particularly beneficial for post-accident repairs or professional vehicle restoration.

Used condition and installation aspects

The offered rear window is a used component, which allows for economical vehicle repair while maintaining the manufacturer's original specifications. Before installation, it is recommended to perform a standard verification of the glass surface, edges, and contact points with the seal and bodywork, as well as to prepare the surface (cleaning and degreasing the frame).

Professional installation using appropriate automotive glass adhesives and primers will ensure system tightness, no leaks, and stable seating of the window in the rear part of the body, which is essential for both safety and cabin acoustic comfort.
