VLT (Visible Light Transmission): is the percentage measure of visible light passing through the window film. The lower the percentage the darker the film. A 5%VLT privacy film is very dark, while a 70% film UV (ultra-violet) film is clear and totally transparent. Dark and transparent UV films all block 99% of Ultra-violet radiation.

Visible Light Reflectance (VLR): is the measure of visible light reflected by the film once applied to the window.

Ultraviolet (UV) Radiation Rejection: is the measure of how much ultraviolet radiation that is being blocked by the film.  UV radiation is the biggest causation of fade destruction of furniture, artwork and valuable possessions in your home.

Infrared Rejection:  indicates how much solar infrared radiation that is blocked by the film. Infrared radiation is the Sun’s energy that provides 49% of the earths heat.

Solar Energy Transmittance: is the measure of solar energy that can pass a particular film.

Solar Energy Absorbed: is the measure of solar energy absorbed by the film.

Solar Energy Reflectance: is the measure of solar energy reflected by a particular film.

Total Solar Energy Rejected: is the measure of the solar energy rejected by a particular film which equates to saving you money on summer cooling bills!

Solar Heat Reduction: is measure of the reduction of solar energy radiating through glass treated with a particular film.

Emissivity: is the measure of radiant energy passing through Low-E Glass that has been treated with a particular film, that will lower heating cost in winter.

U-Factor: U-Factor emissivity measures the heat retaining ability of glass once treated by a particular film, and the rate of heat conductivity of the glass treated with film measured in BTUs/hour/square foot as an R-Rating of “1″. R-Value= 1/(U-Value)

Shading Coefficient: measure of solar heat gain that is capable of passing through a particular film.

Luminous Efficacy: measure of light transmission and shading coefficient capable of passing through a particular film.
