Definitions
Visible Light Transmission
An indicator of how much visible light passes through the glass and into the room.
Ultraviolet (UV) Rejection
An indicator of the amount of ultraviolet (UV) energy that is blocked from passing through the glass.
Total Solar Energy Rejected
An indicator of the films ability to reject solar energy.
Infra-red Rejected
An indicator of infrared blocked at a specific wavelength.
Visible Light Reflectance
An indicator of the amount of visible light that is reflected away from the glass.
Total Solar Absorption
An indicator of how much energy is being absorbed by the glass.
Shading Coefficient
An indicator of the effectiveness of window film in rejecting heat as compared to clear glass.
