Use Good Window Film, but Car's Interior Still Hot. Why?

Often consumers questioned the car window film window film have been installed properly but still in the car still feels hot. Though they may have to spend up to hundred dollars to buy good car window film, or a class instance. When the car (which is already coated glass window film it) dried in the sun, when it should get into the car, the condition inside feels cool. But the reality is not as sweet as their shadows.

Well as a car owner, you need to know a few things why after installing window film car (most good once), heat repellent not really able to withstand the hot temperatures get into the car. Here are some causes:
 
There are three  Causes Why It Still Car Interior Heat After Install Window Film

1. Car colors
 
Black car color is clear and there is no doubt the most colors absorb heat, so it will automatically feel much hotter than the light-colored car like that are trendy white color or silver color trend is over.

2. Comparison of Surface Car with Glass Surface



After the installation of window film, which is protected from the scorching rays of the sun UV and infra red glass is just part only. When dried in the heat of broad daylight, probably only about 20-40% are protected from a total of 100% the entire surface of the car. This means that there are more areas that are not protected than unprotected areas. In areas that are not protected, solar radiation will continue to go without some resistance. Unlike the field of glass that has been coated window film, there will be a majority of the reflected solar radiation so that the heat does not go all the way into.


3. Laws of Physics: Energy Transfer Heat

At the time of sweltering afternoon, the car will have 3 types of heat sources:

1. Radiation

 
Effects of electromagnetic radiation of the sun just as it happened in the house where the temperature in the house got hotter the longer will. To inhibit the effects of this radiation, solar radiation reflectors needed. Commonly used in homes is aluminum foil, while on the surface of the windshield using a window film with a fairly high heat repellent. However, on the surface of the car paint which is the most extensive areas, not the heat repellent coated layer of infrared radiation of the sun, so the sun will be free to penetrate more than 60% of the surface of the car and slowly but surely, will heat up the temperature in the cabin of the car. In my opinion, this is the most effect makes the cabin temperature to be hot during the day. In fact once the sun sets, the effect of heat because the sun was very much reduced.

2. Conduction / Diffusion

Conduction is heat that goes for the heated object. For example, when a metal spoon dipped in a glass of hot water. The heat of the water will dissipate heat propagates to the end of a spoon. In the car, the entire surface is made of metal which is a good conductor of heat, then the temperature will rise quickly so that there will be translucent or heat delivered into the cabin of the car. It can not be avoided unless the surface of the car and the car cabin is made of vacuum or coated layer that inhibits the mediation of heat due to conduction.

Auto glass that has been coated window film car was actually still dissipates heat from conduction effects, for example when the sun during the day and sunburnt, windshield glass that has been coated with a nice movie most will still feel hot to the touch from inside the car. That means there is still heat that goes into the car and because of the effects of conduction.

3. Convection
Convection is the hot air that moves from a higher temperature to a lower temperature in the end will be the same temperature and stabilized or reached equilibrium. Examples are bread oven or grill whichever way it works is the heat element that is blown by the fan continues to spin resulting heat to heat the entire dough bread. So also in the car cabin, on a sweltering afternoon and the weather was hot, the heat will be trying to get into the car cabin temperature lower the temperature on the outside, so that the temperature in the cabin had come up. An example is if the air conditioning suddenly turned off, the temperature in the cabin which had been cold will quickly rise with the temperature of the air outside and coupled with the effects of conduction and radiation. No wonder if the temperature in the cabin can far exceed air temperature outside.

Exposure above may help you understand that installing window film is not a 'cure' to cope with instant heat inside the car cabin. Installing window film is good once it is no guarantee of getting a cool car cabin temperature after drying in the sun. But at least partially reflect the effects of the heat generated by solar radiation, so the sun is not directly felt very hot compared to the glass layer without using a good movie.

So What The Benefits Plugging Car Window Film?

Its main benefit is if the use of window film, when the air conditioner is turned on, it will cool faster than the temperature inside the cabin without the use of window film at all. In addition, quality window film, which has a standard UV repellent up to 99%. It means we are not going to sit in front of the "burnt" hands like after sunbathing on the beach, and the women do not have to worry about her so black and striped.

Furthermore, just choose the brand, color, darkness level figures, numbers and possibly the level of heat repellent glass film technology to suit the car and your budget. To be sure more and more players window film on the market, the more precisely we as a choice for the end user. I personally, I would not choose the most famous brand with the exorbitant price, but choose the best value for money.
