The minimum clearance of non-tempered glass from the floor level of fixed panels is:

The minimum clearance of non-tempered glass from the floor level of fixed panels is established at 18 inches to ensure safety and compliance with building codes. This regulation is particularly significant because non-tempered glass is more susceptible to breakage, and lower installations could pose a higher risk of injury from accidental impacts. By maintaining a minimum clearance, the likelihood of such accidents is diminished, thus enhancing the safety of the space.

Additionally, this height is designed to promote greater visibility while still ensuring that the glass is installed at a height where it is less likely to be impacted by foot traffic or objects. It reflects the balance between aesthetic considerations and practical safety requirements in building design.
