	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 SK microworks 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. SK microworks 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, SK microworks window film provides outstanding durability.
