Glass Floor

Glass floors are made with transparent glass when it is useful to view some-thing from above or below: whereas translucent glass is used when there is no need to view through. In either case. Toughened glass is usually chosen. for its durability and resistance to breakage . 

Translucent floors are sometimes set into outdoor sidewalks and pavements. or the floors of well-lit Interior spaces. to daylight the space below. These are generally called pavement lights. and have a long history. 

Glass as a flooring material is used in both residential and commercial struc-tures. Special hollow glass blocks known as '"glass pavers" are often used in combination with a metal frame. Glass floors are often It from below with natu-ral or artificial light. or may be treated as ordinary floor surfaces illuminated from above.
