Blackout blinds are also called blinds for special tasks. They are placed in rooms whose location exposes them to strong sunlight. They work well not only during the day, but also in the evening, when you want to free the room from all the lights that come from street lamps and other types of artificial lighting. What distinguishes them from classic blinds is the structure of the material. They have an ordinary fabric, but one of their structural elements is also a rubberized layer that does not let light through. Importantly, blackout blinds do not have to be extremely dark.
