The most common, affordable and readily available window tint is dyed film. This has a sticky back to fix it to the window, and then a heat gun is used to stick it properly to the glass. The film appears black from the outside but is relatively clear from within, for good visibility and finish.

• Pros: Affordable, easy to apply, decent tinted finish.
• Cons: Dye can fade over time, average-poor cooling effect and UV protection in the summer.
