ratio of visible light (380~780nm) transmitted from solar radiation energy. The 15% indicates 15% of visible light transmitted. It generally means film concentration. |
|
|
‘External’ number indicates reflection ratio of externally incident light and ‘Internal’ number indicates that of internal visible light. A film with a high ‘Internal’ number reflects the light incident from its rear side, which easily makes eyes tired. |
|
|
Easily overlooked, but it is a factor drivers easily sense. It reduces strong sunlight in daytime or headlights from oncoming traffic at night, and it is an important factor for a comfortable drive. |
|
|
Ratio of hazardous UV rays blocked. It protects driver’s eyes and skin and minimizes vehicle interior deformation. The entire line of SKC vehicle window film products protects against 99% of UV rays or more. |
|
|
IR blocking is measured only for the range of Infra-red, but is very closely related to heat. The higher performance a film is, the higher IR blocking it has in the same concentration and the better Heat Rejection performance it provides. |
|
|
Ratio of total solar energy incident, reflected and absorbed to/by the film. The higher the TSER, the better the thermal blocking performance. Because TSER increases only by raised concentration, it should be considered along with IR rejected. |
|
|
Film clarity. The lower it is, the clearer and more vivid visibility. SKC produces ultra-clear window films in the industry’s lowest 0.4-6% clearness for sale all around the world. |

|
Factor preventing film surface scratches to keep film clear and maintained for a long time. Applying top-class hard coating technology, SKC window film provides outstanding durability. |
