Total Solar Energy Rejected (TSER)
Measures the window film’s ability to reject solar energy in the form of visible light, infrared radiation and ultraviolet light. The higher the TSER number, the more solar energy is rejected way from the window.
Ultraviolet Light (UV)
Invisible, powerful wavelengths (shorter than light but longer than X rays) emitted by the sun separated into three types, UV-A, UV-B and UV-C. UV-B causes sunburn, and prolonged exposure can cause skin cancer. Window films block nearly 100% of ultraviolet light from passing through glass.
Visible Light Transmittance (VLT)
The amount of visible light that passes through the glazing system, expressed as a percent. A lower VLT rating tends to be better for glare control, while a higher rating is preferred for maintaining natural light.
Visible Light Reflectance (VLR)
The amount of visible light that is reflected by the glazing system, expressed as a percent. A higher VLR rating offers better glare control. Films with higher ratings tend to be more reflective and/or darker.
