Purpose and function of the rear window

The presented rear window is dedicated to installation in the rear part of the body, in the area of the tailgate or the rear wall of the W177 series vehicle. It is responsible for proper rear visibility, structural rigidity of the body, and interior sealing against weather conditions. Thanks to the preservation of the factory shape and curvature, the glass works with original seals, moldings, and mounting elements, which facilitates installation and reduces the risk of leaks.

Glass characteristics and color

The glass marked with the AS2 class meets the requirements for light transmission and safety for windows other than the windshield, which is consistent with the typical homologation used in the automotive industry. The green tint of the glass improves the thermal comfort of the interior, limiting the heating of the cabin on sunny days, while giving the vehicle a consistent, factory look. This type of tinting is commonly used in premium class cars because it combines practical function with aesthetics.

Benefits of choosing an original used window

Choosing a used rear window from a Mercedes vehicle is a solution that allows you to maintain factory fit and performance parameters while optimizing repair costs. Original glass from dismantling usually works better with the existing body structure than replacements with universal geometry, which translates into easier installation and a lower risk of stress in the bodywork. A used component of this class is particularly attractive for post-accident repairs, where it is crucial to restore the original rigidity and tightness of the rear part of the body.

Professional installation and technical aspects

The rear window should be installed using appropriate adhesives and primers intended for car windows, in accordance with the vehicle manufacturer's technology. Installation in a specialized service center is recommended, which will ensure:

• proper preparation of the body and glass surface,
• maintaining the correct thickness of the adhesive layer,
• leakage control after installation,
• correct seating in relation to seals and finishing moldings.

Such an approach minimizes the risk of leaks, body rattles, and improper closing of the tailgate.

Safety and OEM quality

Original windows used in Mercedes vehicles are designed with high resistance to small stone impacts, even stress distribution, and predictable behavior in case of damage in mind. In the event of breakage, this type of glass shatters into small fragments with limited sharpness, which reduces the risk of serious injury.
