The Video—Glass Brick

Glass brick is an architectural element made of glass. During the manufacturing process, it is made up of an air-filled cavity and is insulated. It is typically two to three inches thick and can be square or rectangular. Its design allows for a great deal of visual privacy, but still lets in light. Its unique transparency and insulating properties make it ideal for buildings. This building material was originally patented in 1907 and is now commonly used in transparent roofs.
