Glass railings are generally associated with the minimalist and modern style.
Consider installing the frame-less (with clean lines) to create a stunning finished product with wow factor for your stairs.
Glass railings also give you an uninterrupted view when installed on your balcony.
Cleaning and maintenance is easy. Wiping the glass down with a squeegee or spraying it with a hose is sufficient to keep it looking good most of the time.
