In 2012, the Supreme Court of India banned the use of tinted glass and sun films on vehicles for the safety of passengers. The rules governing tinted glass are defined in The Motor Vehicles Act 1988 and state that the visual light transmission (VLT) limit for front and rear windshields are set at 70% and 50% for side windows on all vehicles. On 27 April 2012, the Supreme Court of India ordered black films on windows to be removed.
However, in a country like India, where temperatures are constantly high, it is impossible to drive a car without some protection from the sun. With this mind, you can have tinted glass on your car as long as they fall within the law guidelines. Car manufacturers do provide tinted windows that follow government regulation, but we cannot apply dark films of our choice freely on our car.
Before looking at alternative options, here’s a list of existing tints that are available to car owners.
Dyed Window Tint
Used more for appearance rather than functionality, dyed window tints are a good choice if you are on a budget. They block sunlight using multiple layers of dye, but the dye fades over time from excessive UV exposure. This type of film can block 5-50% of the light from entering your vehicle and they do provide some level of heat reduction, but it doesn’t block as much heat as different types of tint.
Metalized Window Tint
Combining the benefits of dyed window tint with better heat rejection, metalized window tints also filter out heat by reflecting it. These films make use of tiny metallic particles to block sunlight instead of using dye. Although this tint doesn’t fade and has durable features, it interferes with GPS, radio and cell phone signals due to the metal elements within its layers.
Hybrid Window Tint
The hybrid tint is a blend of the advantageous features of both dyed and metalized tints. With the dyed layer, hybrid films can block a fair amount of light, while its metallic parts, it creates a cool, dark appearance. The hybrid tint retains a lighter appearance but manages to block heat, making it one of the most high-performing options comparatively.
Ceramic Window Tint
Considered one of the best options for a window tint, this recent addition offers 99% UV protection and blocks 50% of solar heat without blocking visibility. It contains ceramic particles known for their non-conductive properties, increases shatter resistance and allows radio signals to pass through it.
The Legal Alternative
Asahi India Glass (AIS) has introduced a new legal alternative for tinted windows and sun films. Their Dark Green UV Cut Glass fully complies with the Central Motor Vehicle Regulation for transparency. It is made to absorb energy from solar radiation, cutting down the sun’s heat inside the cabin and eliminating UV radiation by more than 80%. This further reduces the usage of air-conditioning by 10-15%, improving fuel efficiency. With AIS being one of the largest supplies of automotive glass in India, various OEMs have already shown interest to work with AIS and roll out cars with this befitting alternative.
