- Window Films
Percentage of visible light that passes through the window film, captured by light meters. A lighter film results in a higher visible light transmission. A film with lower VLT will block more light from entering through glass.
Percentage of visible light that is reflected by the window film, as measured by reflectance meters. A film with higher VLR will be more effective at controlling glare.
Infrared reduction reading captured by common test equipment at wavelength 1000 nanometers (approximately at room temperature).
Infrared reduction reading captured by spectrophotometers at 1800 nanometers wavelength (approximately summer mid-day sun temperature).
Proportion of solar heat gain when window film is applied, in comparison to a situation where no film has been applied. A lower shading coefficient means that the film is more effective in reducing amount of heat gain.
Percentage of Solar Energy that is reduced after passing through window film. Solar Energy consists of visible light, infrared radiation and ultraviolet light.
Percentage of Ultraviolet light that is obstructed by window film. Ultraviolet light can cause fading and sun damage to skin.
