Skylight refers to a type of roof or ceiling structure that allows natural light to enter a building. Skylights are typically made of transparent or translucent materials, such as glass, acrylic, or polycarbonate, and are commonly used in commercial and residential buildings to provide natural light and enhance the aesthetic value of the space.

Skylights can be classified into different types based on their design and installation methods. Some common types of skylights include fixed skylights, vented skylights, tubular skylights, and domed skylights.

Fixed skylights are stationary and do not open, while vented skylights have a mechanism to allow for ventilation. Tubular skylights are smaller and often used in areas where larger skylights cannot fit, while domed skylights have a curved surface and are often used in industrial or commercial buildings.

Skylights require proper design and installation to ensure they are structurally sound and energy-efficient. They also require regular maintenance, such as cleaning and resealing, to prevent leaks and maintain their longevity.

Overall, skylights are an excellent way to add natural light to a building, improve energy efficiency, and enhance the visual appeal of a space.
