Can photochromic window film reduce heat inside a car?
Yes — photochromic window film reduces heat through two mechanisms. First, when darkened under UV, it reduces visible light transmission which lowers solar heat gain. Second, quality photochromic films like those from our Guangzhou factory include infrared rejection properties — our BL70-25 achieves 95.5% IRR, blocking the primary source of solar heat entering a vehicle. Combined, these properties can reduce cabin temperatures by 8–15°C compared to unfilmed glass, making the car significantly more comfortable and reducing air conditioning load.
