- Dyed film: A layer of dye is absorbed into the polyester film to darken it and absorb some solar heat. It’s the most affordable option and offers good privacy and glare reduction. However, it rejects less heat than other types and can fade or turn purple over time.
- Pigmented film: Fine pigment particles are embedded in the film instead of dye. It holds its color much longer than dyed film and rejects somewhat more heat. It’s a step up in durability for a modest price increase.
- Metalized film: Tiny metallic particles are sputtered or deposited into the film to reflect heat and UV away from the glass. It rejects heat very well and strengthens the glass. The drawbacks are a shiny, reflective look and possible interference with cell, GPS, and radio signals.
- Hybrid film: Combines a dyed layer with a thin metalized layer. You get good heat rejection with less reflectivity and signal interference than a fully metalized film. It’s a common middle-ground choice.
- Carbon film: Carbon particles are infused into the film to block infrared light, which is the main source of heat. It has a matte, non-reflective finish and won’t fade. It also doesn’t interfere with electronic signals.
- Ceramic film: Non-conductive, non-metallic ceramic nanoparticles block infrared heat and up to 99% of UV rays. It can do this even in light shades, so it offers maximum performance with high visibility, no signal interference, and excellent longevity. It’s the premium option.
