Figures are measured on single-pane clear glass; results on your windows will vary. The number in a shade's name is nominal; VLT is the measured light transmission.
Darkness limits for cars are set by each state. Check your state's tint law before choosing a shade.
Visualize the shades: tint preview and heat rejected
The tint preview shows how each shade darkens the view from inside (visible light transmission, VLT); screens vary, so use it as a guide. Heat rejected is total solar energy rejected (TSER): higher is cooler.
