How Often Should Car Window Tint Be Replaced?

[DiAmy]

Car window tint should be replaced based on its wear condition, typically requiring replacement every 3 years or so. Below is relevant information about car window tint: 1. Functions: Its primary functions include blocking ultraviolet rays, reducing heat transmission, preventing injuries caused by shattered glass, and minimizing glare. Additionally, it provides privacy protection through the one-way visibility feature of solar films. Furthermore, it helps protect interior items and occupants from UV damage while lowering cabin temperature via physical reflection, thereby reducing air conditioning usage, cutting fuel consumption, and saving costs. 2. Working Principle: The film utilizes vacuum deposition or magnetron sputtering technology to create multiple layers of high-heat-insulation metal coatings using materials like aluminum, gold, copper, and silver. The outer shell electrons (free electrons) in these metallic materials are generally unbound by atomic nuclei. When illuminated by light waves, the light's electric field causes free electrons to absorb energy and oscillate at the same frequency as the light. This oscillation then emits light of identical frequency to the original, known as light reflection.
