Glass is no longer considered thin and brittle material. Weightless partitions are used instead of walls, traditional floors are changed to transparent products, durable glass stairs are installed instead of the usual models. Modern glass is a reliable material that is actively used for various purposes. It can have various designs in form and design. With the help of modern materials, designers are able to solve many problems. One of them is plexiglass, used in the interior to equip stairs, as a fence for individual areas in the room, or as all-glass partitions between rooms.
