Skylights are windows installed in the roof or ceiling of a building, allowing natural light to enter a space. They can enhance the aesthetic appeal of a room and reduce the need for artificial lighting during the day. Skylights come in various shapes and sizes, including fixed, vented, and tubular designs, catering to different architectural styles and functional needs. In addition to providing light, skylights can improve ventilation when designed to open. They are often made from materials like glass or acrylic and can be energy-efficient, helping to regulate indoor temperatures. Proper installation and maintenance are essential to prevent leaks and ensure optimal performance.
