Definitions for understanding window films?

Below are a few definitions to help you understand how to choose the best window film for you:

Total Solar Transmittance:  The percent of incident solar radiation to be directly passed through a window system

Total Solar Reflectance:  The percent of incident solar radiation to be reflected by a window system.

Total Solar Absorption:  The percent of incident solar radiation to be absorbed by a window system.
Visible Light Transmittance:  The percent of total visible light to be passed through a window system.

Visible Light Reflectance:  The percent of total visible light to be reflected by a window system that can be seen visually.

Percent Ultraviolet Transmittance:  Percent of total ultraviolet light to be passed through a window system.

Percent of Total Solar Energy Rejected: The percent of incident solar energy rejected by a window system, equals solar reflectance plus the part of solar absorption which is reradiated outward.
