What is the connection between wire mesh and fire-rated glazing?

1. It makes the glass flexible

2. It increases the strength of windows

3. It is embedded in the glazing for fire protection

4. It helps in anti-reflective properties

The correct answer is: It is embedded in the glazing for fire protection

The connection between wire mesh and fire-rated glazing lies in its function for fire protection. When wire mesh is embedded within fire-rated glass, it enhances the glass's ability to withstand high temperatures and prevent the spread of flames. The wire mesh serves as a reinforcement, providing structural support to the glass while maintaining transparency. This combination is crucial in applications where maintaining a barrier against fire while allowing visibility is necessary, such as in buildings that require fire-rated partitions or windows. In contrast, the other options do not accurately represent the purpose of wire mesh in this context. While wire mesh can indeed strengthen glass in general, its primary role in fire-rated glazing is specifically to improve fire resistance rather than just increasing strength. Additionally, wire mesh does not contribute to making the glass flexible or improving anti-reflective properties; those characteristics pertain to other types of treatments or glass designs.
