Glass walls have long been a popular design element for commercial spaces, such as offices, restaurants, hotels and spas. Over the years, designers and architects relied on this space saver for smaller urban dwellings, where the transparency of glass can both preserve and define space. Now, every modern home contains some form of frameless glass walls such as glass wall panels for sunrooms, glass wall divider, glass wall shower, glass knee-walls and glass wall closet partitions.
