ASWF Firewall
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.

| Shade | Visible light transmitted Visible light transmitted. Share of visible light that passes through the glass and film. Lower is darker. | Visible light reflected, outside Visible light reflected, outside. Share of light the window reflects outward: how mirror-like it looks from outside. | Visible light reflected, inside Visible light reflected, inside. Share of light reflected back into the car or room: how much you see your own reflection at night. | Total solar energy rejected Total solar energy rejected. Share of the sun's total energy (heat) kept out. Higher is cooler. | Solar energy transmitted Solar energy transmitted. Share of the sun's energy that passes straight through the glass. | Solar energy reflected Solar energy reflected. Share of the sun's energy reflected back outside. | Glare reduction Glare reduction. How much less visible glare than the same glass with no film. | Solar heat gain coefficient (g-value) Solar heat gain coefficient (g-value). Fraction of the sun's heat that ends up inside, from 0 to 1. Lower is cooler. | Shading coefficient Shading coefficient. Solar heat gain compared with plain 1/8-inch clear glass, from 0 to 1. Lower is cooler. |

- Glare reduction. How much less visible glare than the same glass with no film.
- SHGC
- Solar heat gain coefficient (g-value). Fraction of the sun's heat that ends up inside, from 0 to 1. Lower is cooler.

Figures are measured on single-pane clear glass; results on your windows will vary.
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.
