New Convertible Rear Window - Glass Vs Plastic

At a certain point in the lifetime of a convertible car, the top will have to be replaced. Canvas or vinyl convertible tops can typically last up to ten years with good maintenance habits. When it is indeed time to replace the top, a decision must be made whether to replace with a glass or plastic window. Most cars will allow for the capability to choose between the two, though a few cars were designed for one or the other. When replacing a convertible top, understanding some of the issues that arise with either material will shed light on the decision making process.

Plastic Window

Plastic rear windows are standard on a lot of convertible cars. When they are new, the windows are great. They are functional, flexible, and lightweight. The main problem will be that the aging process which will occur is far more accelerated than the top itself. Within a couple of years the plastic will either be severely discolored or fogged, making the window a safety hazard and an eye-sore. Therefore, within the lifetime of the convertible top, the window will likely need to be replaced at least once. Depending on the model of the vehicle, this may be easier to take care of, but in general replacing the plastic window is a hassle and an expense.

Glass Window

Although many convertibles come with plastic windows, an equal number either have a glass window option or come standard with a glass window. The main benefit of these windows is that, just like with a standard vehicle's window, they will maintain their clarity and durability. The main concern with a glass window is that they are not flexible like the plastic, and a small complication in the cars convertible closing mechanism can result in a shattered window. Additionally, if a car is designed for a plastic rear window, a replacement top with a glass window may need to be smaller in order to fit in the car's boot; the limited rear view may be a concern to some drivers, but to most it's just personal preference.

To conclude, it is safe to say that in most situations a convertible owner will want to opt for a glass window on their replacement top. In general, owners of a convertible with a glass window will not replace the top with a plastic window; the decision will usually apply more to the owner of a plastic rear view convertible. Thus, it is important to consider the car's design and whether or not the chance of a shattered or smaller rear view will be a large concern. Other than that the best choice is pretty simple: A replacement top with a glass rear view window.
