Skylight typically refers to a window installed in a roof or ceiling, designed to allow natural light to enter a building. Skylights are often used in spaces where regular windows are impractical or insufficient to provide adequate lighting, such as attics, stairwells, or rooms with limited access to external walls. They can enhance the aesthetic appeal of a room and provide energy savings by reducing the need for artificial lighting during the day. Additionally, skylights can offer views of the sky and stars, contributing to a sense of openness and connection to the outdoors within an indoor space.
