Glass block, or on the other hand glass block, is a glass engineering component that concedes light while keeping up with visual protection because of its clear properties. The first patent for glass block, recorded in 1907, portrays it as a course of intertwining two areas of glass into a solitary square with an empty community. This one-of-a-kind blend works with the material's clarity and along these lines its properties of light-giving and protection, too its protecting characteristics like a sound stifling, energy protection, and insulating.
