Red Seal Glazier Practice Exam

What are the two main categories of glass used in construction?

1. Clear glass and decorative glass

2. Frosted glass and tempered glass

3. Annealed glass and safety glass

4. Colored glass and patterned glass

The correct answer is: Annealed glass and safety glass

The two primary categories of glass used in construction are indeed annealed glass and safety glass. Annealed glass is the most basic form of glass that is produced through a straightforward cooling process, making it suitable for general applications. It is often used in windows and other elements where structural integrity is not a critical concern. Safety glass encompasses various types of glass that are designed to reduce the risk of injury when broken. This category typically includes toughened (tempered) glass, laminated glass, and other products that abide by safety standards. Safety glass is essential in many applications, like automobile windows, shower doors, and glass facades, where extra strength and safety features are necessary. Understanding these two categories provides insight into their applications and importance in ensuring both aesthetic qualities and structural integrity in construction.
