What is the ideal heat insulation rate for solar films?
1 Answers
Solar films with higher heat insulation rates are generally better, and products exceeding 50% can typically be considered high-quality. Additional information about automotive window films is as follows: 1. Overview: Automotive window films (Auto-tint-film) involve applying a thin film layer to the vehicle's front and rear windshields, side windows, and sunroof. This film layer is also referred to as solar film or heat insulation film. 2. Functions: Primarily, it blocks ultraviolet rays, reduces heat penetration, prevents injuries from shattered glass, and minimizes glare. Additionally, due to the one-way visibility feature of solar films, they help protect personal privacy.
