WINDOW FILM
Filtering direct sunlight into spaces also allows you to use those rooms which seem to always be unused regularly during certain times of the day when direct sunlight comes in and creates excessive heat. With window film, it will reflect the sunlight and only a minimal amount of heat from the outside and dissipate it throughout the room.
You will also benefit through energy savings of as much as 30% in the monthly energy bill. This is because, window film filtered the sunlight not allowing much heat to come in.
