What the column names mean
- VLT
- Visible light transmitted. Share of visible light that passes through the glass and film. Lower is darker.
- VLR out
- Visible light reflected, outside. Share of light the window reflects outward: how mirror-like it looks from outside.
- TSER
- Total solar energy rejected. Share of the sun's total energy (heat) kept out. Higher is cooler.
- UV
- Ultraviolet blocked. Share of ultraviolet light blocked, the part that fades interiors and harms skin.
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. Archived specs may differ from what was sold near the end of the line.
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.
