Do Privacy Windows Still Need Heat Insulation Film?
2 Answers
Privacy windows still require heat insulation film because the film offers many functions that privacy glass lacks. Below is a detailed introduction to the pros and cons of car window films: Good Privacy Protection: Generally, car window films are one-way, which helps protect the owner's privacy, but owners need to verify this when selecting a film. Anti-Explosion Effect: In case of an accident, the film can hold shattered glass together, preventing shards from flying and protecting passengers. Heat Insulation: High-quality car window films provide heat insulation, effectively controlling temperature rise inside the car in summer and retaining warmth in winter, creating a comfortable driving environment. Reduced Light Transmission: Car window films have a light transmittance of no more than 90%, especially when applied to the windshield, which may reduce visibility and affect driving safety.
I think privacy glass does provide sun shading and privacy, but when it comes to heat insulation, it may not be sufficient. My car came with factory-installed privacy glass, but during summer drives under intense sunlight, my arms still get scorched, and I have to crank up the AC, which naturally increases fuel consumption. Regular heat-insulating films might be cheaper, but the performance difference is significant—they’re specifically designed with metallic layers to reflect heat and block 99% of UV rays, protecting the car’s paint and interior from aging. As for privacy? A light-tinted film is enough and won’t affect visibility at all. If the budget allows, I highly recommend adding a professional heat-insulating film. That cool, comfortable feeling while driving is undeniable, and it also helps with long-term vehicle maintenance.
