How to Distinguish the Quality of Car Window Films?
2 Answers
Distinguish the quality of car window films from these aspects: 1. Clarity: High-quality films allow clear visibility of objects beyond 6 meters at night, while inferior films appear foggy and are easily distinguishable. 2. Texture: Genuine films feel thick and smooth to the touch, whereas inferior films are thin, brittle, and prone to wrinkling. 3. Color: High-quality films have pigments evenly fused into the film, ensuring durability and resistance to discoloration; they won't fade even when scraped during installation. Thermal insulation performance is one of the key indicators of glass protective films.
I usually enjoy researching automotive accessories, and distinguishing good car films starts with the materials. The material is crucial; high-quality films typically use high-strength polyester or nano-ceramic layers, making them feel sturdy and flexible, resistant to tearing or bubbling. UV and heat insulation performance should be tested—good films block 99% of UV rays and have high heat insulation efficiency, with a noticeable temperature difference when touched in summer. Light transmittance also cannot be ignored; front windshield films should have over 70% light transmittance to avoid obstructing vision, while poor-quality films appear dark and blurry. The aging test is simple: check for fading or cracking after a few months of sun exposure. When selecting a film, inspect the label—those with metal layers are more durable, but metal films may interfere with signals, so this needs to be balanced. Avoid buying no-name products; spending more on quality truly saves hassle.
