Purpose and fitment

The presented glass has been designed specifically as a rear side element for the left side of the vehicle, which guarantees correct seating in the door or body frame and compatibility with factory seals and trim strips. Proper edge profiling facilitates installation and reduces the risk of stress that could lead to cracks or leaks.

By maintaining the original specification, the glass works with factory mounting points and guide elements, which is particularly important for maintaining body tightness and the correct operation of opening mechanisms, if the specific body variant features them.

Technical characteristics of the AS3 glass

The AS3 marking indicates a specific standard of automotive glass, including an appropriate level of tinting and light filtration. This type of glass is often used in the rear part of the vehicle to improve the thermal and visual comfort of passengers and to limit interior heating. At the same time, transparency is maintained, which is sufficient for safe observation of the surroundings by the driver and passengers.

The use of glass with controlled thickness and structure translates into dimensional stability and resistance to typical operational loads, such as body vibrations or temperature differences. As a result, the glass maintains its properties for a long time, provided it is correctly installed and used.

Condition of the item and benefits of choosing a used part

The offered glass comes from the used parts segment, which allows for a reasonable repair cost while maintaining the manufacturer's original specification. In practice, this means a better fit than in the case of many non-original replacements, as well as visual consistency with the vehicle's other windows.

Choosing an original used glass is particularly beneficial for post-accident repairs or when replacing damaged body elements, when the goal is to maintain the factory character of the car without introducing unnecessary differences in glass shade or edge shape.

Safety, comfort, and practical application

A properly selected rear side window is important not only for aesthetic reasons but also for functional ones. It influences:

• lateral body stiffness in the rear section of the vehicle,
• proper visibility in the rear-side zone,
• noise reduction in the cabin thanks to proper adhesion to seals,
• thermal comfort of passengers thanks to the tinting characteristic of the AS3 standard.

Proper fitment of the glass to the specific model minimizes the risk of leaks, fogging, and unwanted wind noise when driving at higher speeds.
