Is a panoramic sunroof equipped with a sunshade or a sun visor?

A panoramic sunroof can be equipped with either a sunshade or a sun visor, depending on the usage scenario. Below are some drawbacks associated with panoramic sunroofs: Prone to turning into an oven: While panoramic sunroofs offer an excellent sense of openness, direct sunlight entering the cabin can significantly raise the temperature. Difficulty in noise control: The thin glass used in panoramic sunroofs provides less insulation against external noise compared to traditional roof linings. This results in noticeable wind noise during driving, and the sound of rain can be even more directly transmitted into the cabin. Susceptibility to leaks due to aging seals: Compared to standard sunroofs, panoramic sunroofs utilize larger sealing strips and adhesive bonding. Over time, improper maintenance, such as prolonged exposure to sunlight, can accelerate the aging of these components. Additionally, unlike conventional roofs that rely on drainage channels, panoramic sunroofs primarily divert water along the surface of the bonded areas, lacking dedicated drainage pathways. This design can eventually lead to water leakage issues.
