What is the minimum thickness required for all glazing used in handrail, guardrail or guard section?

The minimum thickness required for all glazing used in handrail, guardrail, or guard sections is typically 1/4 inch. This standard is set to ensure that the glazing maintains a durable and safe barrier while also providing adequate visibility. Glass of this thickness is commonly used in applications requiring safety measures due to its strength when properly tempered or treated.

Using thicker glass, like 1/2 inch, 3/4 inch, or 1 inch, is not necessary for standard applications but could be specified for extraordinary conditions or design intents. However, for typical handrail and guard situations, 1/4 inch tempered glass meets the necessary load requirements and safety standards while being economical and visually appealing.
