As per the Supreme Court ruling, films that reduce visibility below 70% (front/rear windshields) and 50% (side windows) are prohibited. However, manufacturers now offer sun films that comply with legal limits while still offering high UV and IR rejection. Many models listed, like QV70 and U70S, offer up to 70% VLT while still blocking 99% UV and high infrared radiation—perfectly legal and highly beneficial.
Whether you’re navigating the traffic-filled streets of Delhi or driving through the blazing heat of Rajasthan, your car’s interior and comfort matter. Automotive window film, often called car sun film, isn’t just about enhancing a vehicle’s aesthetic. It serves critical purposes—ranging from UV protection to energy savings.
In this guide, we explore the science and benefits behind window films, debunk legal myths, and explain why this small upgrade can make a big difference in your driving experience.
Understanding the Technology: VLT, IR, UV, and TSER Explained
Before choosing the best window film for cars in India, it’s essential to know what the specifications mean and why they matter:
VLT – Visible Light Transmission
Definition: Measures how much visible light passes through the film.
Range in top films: 53% to 72%
Importance: A higher VLT means clearer visibility. In India, legal front side and rear windows must allow at least 70% light in.
IR – Infrared Rejection
Definition: Measures the percentage of infrared heat blocked.
Range in top films: 92% to 99%
Importance: High IR rejection keeps your car cabin cool, reducing the need for excessive AC use.
UV – Ultraviolet Rejection
Definition: Measures how much harmful UV radiation is blocked.
Range: 100%
Importance: Reduces the risk of skin damage and fading interiors.
TSER – Total Solar Energy Rejection
Definition: Measures how much total solar energy (UV + visible + IR) is blocked.
Range: 44% to 86.90%
Importance: The higher the TSER, the better the film reduces total heat inside your car.
Benefits of Vamford High-Quality Car Window Tint FilmProtects You from Harmful UV Rays
Prolonged exposure to UV rays can lead to skin aging, sunburns, and even skin cancer. High-quality window film like the ones with 99% UV rejection ensures both driver and passengers are safeguarded during long drives.
Reduces Heat Inside the Cabin
Thanks to high IR and TSER ratings (as seen in models like QD60 and U70), your car remains cooler, reducing the dependency on AC systems and improving fuel efficiency.
Reduces Glare for Safer Driving
Low VLT films can significantly reduce glare from the sun or oncoming vehicles, making driving safer—especially during early mornings and late afternoons.
Preserves Interior Quality
UV rays can cause leather seats to crack, dashboards to fade, and interiors to age prematurely. Car window film preserves the value and aesthetics of your vehicle.
