Purpose and fitment

The presented window has been designed specifically for the Touring body style, with the placement on the vehicle defined as rear – right side. This means that the shape, curvature radius, and mounting method are adapted to the factory mounting points in the BMW 3 Series E91, which facilitates correct installation and maintains the body's seal.

Thanks to its design compliant with the original BMW standard, the component integrates well with the side line of the car, maintaining the aesthetics and functionality of the factory glazing.

Characteristics of AS3 glass and tinting

Glass marked as AS3 is a type of tinted window used in the rear zone of the vehicle. The increased level of darkening reduces the penetration of sunlight into the cabin, which translates into:

• reduced interior heating during parking and driving in the sun,
• improved thermal comfort for passengers in the rear seat,
• better protection of transported luggage from prying eyes.

Tinted glass also helps reduce glare, which can improve visual comfort during long journeys. At the same time, clarity suitable for rear side windows is maintained, in accordance with the typical use of AS3 class glass in passenger cars.

Performance parameters and role in body construction

As an element from the Car windows group, this rear side window performs several important functions in the vehicle's construction:

• seals the side part of the body in the rear passenger zone,
• stabilizes the glazing line in the estate body,
• works with seals and mounting strips, ensuring proper rigidity and the absence of unwanted vibrations.

A properly selected window helps reduce wind noise and maintain proper acoustic conditions inside the cabin. In the case of replacement after a collision or mechanical damage, the use of original glazing is crucial for maintaining the proper fit of body components.

Condition, origin, and use in repairs

The offered window is a used component, which allows for economical vehicle repair while maintaining the original character of the equipment. This type of part is particularly useful in situations where replacement is necessary after a window is broken, damaged during a break-in, or following post-accident repairs to the rear part of the body.

Choosing an original side window from dismantling is a cost-effective solution that also allows for maintaining visual consistency with the rest of the vehicle's glazing, without the need to use replacements with a different shade or degree of tinting.

Operational comfort and related elements

Tinted rear windows in an estate car have a direct impact on the operating conditions of the air conditioning and interior cooling system. Reducing cabin heating lowers the load on the air conditioning system, which can indirectly affect fuel consumption and the durability of components responsible for heat dissipation. If you want to better understand how ambient temperature affects vehicle components, it is worth reading the guide: Summer heat vs. cooling system load and ways to cheaper repairs.

When planning a comprehensive repair or upgrade of the car, it is good to also consider other used body and equipment elements to optimize service costs while maintaining the appropriate quality of parts.
