What must be the minimum thickness of glazing in a guardrail?

The minimum thickness of glazing in a guardrail is typically set at 1/4 inch. This specification is based on safety standards that aim to ensure the glass can withstand appropriate loads and impacts while also providing adequate visibility. Thicker glass may be used for additional strength or to meet specific design requirements, but 1/4 inch is the baseline thickness that is often recognized in building codes and safety regulations.

Glazing in guardrails must not only fulfill structural integrity but also ensure pedestrian safety, which is why these regulations are in place. Adequate thickness helps prevent breaking or shattering under pressure, thereby enhancing safety in commercial buildings.
