Quarter Window Replacement

What is the Quarter Window?

The quarter window also referred to as the quarter glass or valence window is the last glass on the side of a vehicle. It is behind the rear door of a vehicle and before the back glass or rear windshield. The quarter window is in most cases positioned above the rear wheel. The quarter glass is never attached to the rear door. In most cars the quarter glass is stationary, but for longer length vehicles the quarter glass does come retractable.

What does the quarter window do?

The quarter window is used to help see the surrounding areas. It is also used to allow more ventilation in cars with a third row of seats. Older model vehicles have a latch that the passenger has to manually unfasten to tilt out the window, but modern vehicles are now equipped with power controls to operate the tilting mechanism electronically. The quarter glass should not be mistaken for opera glass which are typically mounted in the C-pillar of older cars that were popularly designed during the 1970s and early 1980s and most often have a vinyl roof.

More about the quarter window

The quarter window is made with the same tempered or laminated glass as the side windows and rear windshield. The tempered glass is designed to shatter into tiny glass pieces to prevent harm. The laminated glass is designed to only crack in order to keep the glass intact in the panels of the vehicle.
