What Are the Types of Car Window Films?
2 Answers
Here are the types of car window films: 1. Traditional dyed film. Characteristics of dyed film: no metal coating, low visible light transmittance, poor heat insulation performance, prone to fading, and easy to bubble after long-term use. 2. Single-layer metal film. It achieves heat insulation by reflecting visible light. Its characteristics include: high reflectivity or mirror-like appearance, likely to cause light pollution, mostly made by single-layer metal spraying with uneven metal coating. Some materials are produced through evaporation treatment or sputtering spraying process, lacking spectral selectivity. 3. Heat-absorbing film. Poor thermal control performance. Its characteristics include: adding heat-absorbing chemicals to the adhesive, producing short-term heat insulation effect, generating secondary radiation after saturation, with far-infrared rays posing more serious harm to the human body, lacking spectral selectivity. Uneven heat absorption can easily cause glass breakage. 4. Heat-reflecting film. Produced using magnetron sputtering technology, featuring spectral selectivity. Its characteristics include: excellent heat insulation performance; made by multi-layer sputtering of precious metals, reflecting a large amount of heat; rarely produces secondary radiation phenomenon.
After years of driving, I've noticed there are quite a few types of car window films. The main categories include: Heat-insulating film is the most commonly used type, reducing interior temperatures in summer and ideal for long-distance driving; explosion-proof film, also known as safety film, prevents glass shards from scattering upon impact, protecting passenger safety; privacy film has a darker tint to prevent outsiders from peering into the car, making it practical for urban commuting; dyed film is affordable and allows for custom colors to enhance the vehicle's appearance; there are also ceramic and metallic films—ceramic films don't interfere with signals, while metallic films are more durable but may affect mobile reception. When choosing, consider your driving habits: opt for heat-insulating film in hot southern regions, or explosion-proof film if you frequently transport children. Professional installation is crucial to avoid bubbles or impaired visibility, and annual cleaning and maintenance can extend the film's lifespan.
