A skylight is a window installed in a roof or ceiling designed to admit natural daylight into interior spaces. By enhancing natural light, it reduces the need for artificial lighting, improving energy efficiency. Properly installed skylights also contribute to ventilation and can enhance the aesthetic appeal of a room, making spaces feel more open and inviting. Selecting the right skylight involves considering factors such as size, glazing type, and placement to maximize light while minimizing heat loss or gain.
