Should the sunroof be tinted?

Car sunroofs do not need tinting because the sunroof glass usually already has UV protection and heat insulation functions. Applying film again would result in a certain degree of resource waste and could have some impact on the overall vehicle quality. Below is relevant information about car sunroofs: Functions: Changes the traditional ventilation method; prevents exhaust fumes from entering the car; reduces wind noise; quickly lowers the interior temperature; rapidly removes interior fogging; and can broaden the field of vision. Installed on the roof, car sunroofs effectively facilitate air circulation inside the vehicle, increasing the intake of fresh air. Additionally, they can expand the field of vision and meet the needs of mobile photography and videography. Opening methods: There are two opening methods: tilt-up and slide-open. The tilt-up method uses the airflow over the roof to create negative pressure for 'extraction,' which, combined with the external circulation, can effectively cycle the interior air. The slide-open method allows for positive pressure intake.
When it comes to whether to apply film on the sunroof, it really depends on personal needs. Living in the southern region, driving under the scorching summer heat with that heat pouring in through the sunroof is quite unbearable. Last year, I applied a specialized ceramic heat-insulating film, and the UV-blocking effect was remarkably noticeable. Driving under the sun, my head no longer feels the burn, and it even helps save some air conditioning power. However, it's important to choose a light-colored film; going too dark makes stargazing difficult at night and can obstruct the rearview mirror. Additionally, sunroofs are designed with anti-shatter features, so avoid using metal-coated films to prevent interference with the glass's normal breakage during emergency escapes. For those who park in underground garages year-round or drive in northern regions, applying film might not offer the best cost-performance ratio.
Based on my car ownership experience, whether to tint the sunroof depends on the vehicle model. For panoramic sunroofs with large glass areas, applying a heat-insulating film can indeed enhance comfort, especially for sun protection when traveling with kids. However, for regular small sunroofs, it's not worth the expense as factory glass usually comes with UV protection coating. Additionally, maintenance costs should be considered – standard films degrade and fade in four to five years, and removing old film can be more troublesome than installation. A friend's sedan had adhesive residue after film removal, requiring special solvents for cleanup. Nowadays, magnetic sunshades are more practical – they block sunlight in summer and can be removed in autumn/winter without obstructing the view.
