In which Group are screens not required if fully tempered glass is used?

Fully tempered glass is often used in scenarios where enhanced safety is needed due to its increased strength and thermal resistance. When it comes to building codes and regulations, there are specific groups or classifications for residential occupancy that determine requirements for safety features like screens.

In the case of fully tempered glass, building codes have provisions that state that screens are not required when this type of glass is utilized, primarily because fully tempered glass is less likely to shatter under stress compared to standard glass. The objective of these regulations is to ensure the safety of residents while allowing for flexibility in design and construction practices.

In the context of the groups R-2, R-3, and R-4, which correspond to different types of residential occupancies, the use of fully tempered glass offers a level of safety that negates the need for additional protective screens. Since this applies uniformly across these classifications, it follows that if fully tempered glass is installed, screens are not mandated across all groups. This understanding is crucial for compliance with safety standards in commercial building inspections.
