KEY TERMS

Visible Light Transmission (VLT): Measures how light or dark the film is. The lower the number, the darker the film. 

 

 

 

 

 

 

 

 

Visible Light Reflectance (VLR): Measures the percentage of visible light that is being reflected by the window film. 

The higher the number, the more shiny the appearance. 

 

 

 

 

 

 

 

 

UV Rejection (UV%): Measures how much of the Ultraviolet A and B rays the film blocks when applied to glass.

 

 

 

 

 

 

 

 

Shading Coefficient (SC): Measures the net benefit of a window treatment to reduce heat gain. Utility companies 

often endorse films with a shading coefficient of .50 or lower. 

 

 

 

 

 

 

 

 

Emissivity (EMIS): Measures how efficiently a window system reflects heat back towards the source of the heat, 

whether the sun in the summer, or furnace in the winter. The lower the number, the better the insulating quality. 

 

 

 

 

 

 

 

 

Total Solar Energy Rejection (TSER): Measures the film's ability to keep infrared heat, UV rays, and visible light from

entering the living area. The higher the number, the more comfortable you should be; because it is both reflecting 

and absorbing solar energy, the film will feel warm to touch.

 

 

 

 

 

 

 

 

U Value: Measures heat transfer through glass due to to outdoor/indoor temperature differences. The lower the

u-value, the less heat transfer. 

All data were obtained from typical production materials and are subject to normal manufacturing

 tolerances. All tests were performed on single pane windows with clear 1/8" glass.
