What are the differences between residential window film and automotive window film?

1. Different Functions

Residential window film is directly applied to the interior surface of household windows. Its primary functions include correcting uneven lighting, dispersing uncomfortable glare, providing sound insulation, heat insulation, and privacy protection, with a primary focus on heat insulation and UV protection. On the other hand, automotive window film is typically applied to car windows and primarily serves to block UV rays, reduce heat, and prevent sudden glass shattering, with a strong emphasis on safety and anti-shatter properties. Additionally, automotive window film can contribute to insulation and, to some extent, fuel savings.

2. Different Performance Characteristics

There are notable differences in performance parameters such as light transmittance, reflectance, absorption rate, tensile strength, fracture strength, puncture resistance, and more. These differences arise from distinct design priorities: residential window film emphasizes indoor comfort and privacy protection, while automotive window film prioritizes safety, transparency, and ease of inspection.
