Skilight

Skylights are structures of different size and shape primarily helping in transmitting light into the building. They either form the complete roof structure or they may fit partially into the roof to perform its intended day-lighting purpose. They are made of glass, acrylic or polycarbonate and are essentially transparent or translucent structures that allow light to pass through. Skylights might include such structures like roof windows, tubular daylighting devices, and sloped glazing roofs. The other purpose of skylights apart from day-lighting is the visual connection it provides to the entire structure from both inside and outside.
