Since modern glass making was revolutionized in the 1950s, glass has been increasingly used for interior and exterior building applications due to its visibility and versatility. Glass railings are excellent examples of this, adding visibility and versatility to decks, balconies, stairways, pool enclosures, and more. Safety is a main purpose of railings and glass railings are an unobtrusive way to provide safety where you need it, whether inside or outside.
