Our photochromic film self-regulates solar heat rejection and daylight comfort. At high sunlight intensity, on a sunny day, the film rejects solar heat and tints. This reduces the required energy to cool your building and cuts off annoying glare inside. Under low sunlight intensities, during the evening or in cloudy weather conditions, the film allows solar heat and gains transparency. This allows natural heating of indoor spaces and entrance of daylight at the moments during the day this is most needed.


Our photochromic film self-regulates solar heat rejection. Therefore, the film saves up to 20% more energy compared to conventional solar control glass films in temperate climates. In warm, sunny climates the film can even save up to 42% of energy on a building’s annual energy consumption.


The film adapts its visible light transmission based on the sunlight intensity. This way, the window film self-regulates a comfortable amount of daylight and prevents annoying interior glare when needed.


The photochromic film is as easily installed as a conventional glass film and thus shares similar cost benefits. There is no electronic wiring required to switch the optical properties of the film as with electrochromic solutions.
