How Often Should Car Black Roof Film Be Replaced?

[CharlesAnn]

Car black roof film should be replaced approximately every 5 years. The functions of car film include: 1. Providing heat insulation in summer, saving air conditioning energy; 2. Reducing heat loss in winter to maintain interior temperature; 3. Blocking UV rays to prevent direct exposure to interior furnishings, thereby extending their lifespan and quality; 4. Reducing glare to ensure safe and comfortable driving. Post-installation precautions for car film include: 1. Avoid rolling down windows for 3 days; 2. Do not clean the heat-insulating film or turn on the defogger heating wires for a week; 3. Avoid using nails or sharp objects to lift the film edges to prevent dirt from entering; 4. Refrain from attaching suction cup items to the film for 1 to 2 weeks; 5. Address bubbles, displacement, or blurred vision on the film promptly by a professional technician to avoid compromising driving safety.
