Properly contoured edges and the correct glass thickness ensure proper seating in the frame and compatibility with factory seals. Such fitment reduces stress on the bodywork and helps maintain the proper side rigidity of the vehicle.

The AS2 glass type marking indicates the use of appropriate tempering and filtration technology, which translates into driving comfort, protection against glare, and compliance with homologation requirements for side windows.

Performance parameters and role in safety

The side window in the rear part of the vehicle plays an important role in terms of visibility and passenger safety. Appropriate transparency and glass surface quality facilitate observation of the surroundings, which is important during parking maneuvers and lane changes. At the same time, the properly selected glass structure helps to reduce wind noise and vibrations transmitted into the cabin.
