Glass Panel Roof
A glass panel roof is a type of window that covers part or all of the roof of the car. It is made of laminated glass, similar to windshields.
A glass panel roof allows for natural light and ventilation to enter the car and enhances the aesthetic appeal and spaciousness of the interior.
A glass panel roof can be either fixed or movable. A fixed glass panel roof is permanently attached to the car frame and cannot be opened or closed. A movable glass panel roof can be opened or closed by using a button, a switch or a hand crank. A movable glass panel roof may be considered as an extension of the power window concept.
The smallest category of glass roof is a sunroof. This is a glass panel placed above first row. This was the type of glass roof available back in the 80 and 90.
Panoramic roof with front opening

The glass used typical protect against sun heat by reflecting most of the UV rays and allowing some of the heat to radiate out through the glass. However, some manufacturers add addional blending to reduce heat or increase privacy.
Curtains for glass roofs on cars are also known as sunshades or sunroofs. They are designed to block the sunlight and heat from entering the vehicle through the glass roof.

It allows the driver to control the intensity of light from transparent to opaque with a push of a button. Some car manufacturers, such as Rivian, BMW and Porsche, offer this option for their models.
