Johnson Window Films InsulatIR

Current Status checked September 2026

Johnson's nano-ceramic car film line, including very light shades (up to 85%).

Nano-ceramic film uses very fine ceramic particles to block infrared heat. It gives high heat rejection even in light shades and doesn't interfere with signals. Compare the types of window film.

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.
Sel. IRR
Selective infrared rejected. Infrared blocked at the wavelengths the maker picks. It reads higher than IRER and differs from brand to brand, so compare it only within one brand.
UV
Ultraviolet blocked. Share of ultraviolet light blocked, the part that fades interiors and harms skin.
Glare
Glare reduction. How much less visible glare than the same glass with no film.

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.
