![]() ![]() The shades of car window tints range from 50% to 5% VLT, where 5% is the darkest shade. They even have rules and regulations to curb such illegal car window tinting. Due to such security concerns, most countries have laws limiting the darkness percentage of vehicles. Most of the time, dark-tinted vehicles are used for illegal and criminal actions as it provides protection to the passengers due to low visibility. This would interrupt the vision of the driver and is commonly known as the ‘Bubble Effect’. Also, the tint would separate from the glass due to wearing off with time and create air bubbles trapped inside the film. ![]() This would create negative impacts on older drivers and create road accidents. Thus, the vision would be blurred naturally. The car window tints reduce the threshold contrast of light. Let’s refer to some disadvantages of having dark tint on car windows. The advantages of tinting car windows have been discussed in our previous article on Types of Window Tint. Advantages and Disadvantages of Tinting Car Windows It also prevents theft as the interior cannot be seen from the outside. This is mostly used in commercial vehicles and VIPs for extreme privacy. Hence, the glasses would look almost black and commonly known as ‘limo tint’ or ‘dark tint’. This is the darkest effect as only 5% of light is allowed to pass through the film. It is also known as ‘medium tint’ or ‘midnight tint’ by some manufacturers. Therefore, it is commonly referred to as the ‘factory tint’. This is the shade created in most of the newly manufactured vehicles. Therefore, it blocks more sunlight and gives more protection from UV radiation. This creates a darker effect on the car windows. This shade is known as ‘light smoke’ and creates a mild classy look on the vehicle. In addition, this is the average shade percentage that is allowed in all the states. This is one of the best shades of tint that moderately blocks both heat and harmful radiation. They are almost clear like glass but may be subjected to various glass conditioning procedures.Īs indicated, 50% of the sun rays are blocked and only half is allowed to penetrate into the interior of the car. These are the factory-installed, regular type of windows that is clear and does not have any shade. Some of the common percentages of window tints are shown below. The Visual Light Transmission percentage (VLT %) represents the percentage of visible light that can penetrate the window film. Even though the industry may not be at its peak at present, the tinting still continues with even more advancements of technology. The industry of car window tints reached its highest market during the mid-1990s. Here, a shade percentage of 35% was allowed for side windows and the rear glass. Later, the dyed or colored film of tint was introduced. With the increasing popularity of window tints, new laws and regulations were created and this is where the Visible Light Transmission factor came into existence. The metallic combination and alloy technology were introduced in the 1980s. The scratch-resistant property was added in the late 1970s. ![]() The reflective and flat films originated in Western Australia in the mid-1970s. A few years later, the thick mounting adhesive was introduced for enhancing security on cars. Towards the early 1970s, a dyed film of metal was introduced that reduced the reflective appearance. It was also scratched easily and hence the quality was low. Therefore it couldn’t be used for vehicles. This created a highly reflective look, almost mirror-like. This was created by spraying a coat of vapor on a film of clear polyester using mounting adhesive. These were used for the windows of buildings and offices. The friction on land vehicles caused a lack of durability, unlike in space travel where there is no friction.Īfter about a decade, a tougher form of window tint was developed which was less expensive. Nevertheless, one main drawback was that these tint films were more expensive with respect to the price of cars. Along with time this technology was used for heat elimination on-road vehicles. The first use of tint films was in the space mission, Apollo. In the earliest stage, tints were created for the space shuttle industry so as to reflect heat during space travel. ![]()
