Rationale: Glazing refers to the installation of glass or similar
transparent materials in windows, doors, and facades.
Correct Answer: B. Providing transparent or translucent
enclosure openings
2. Which material is most commonly used in modern
architectural glazing?
A. Tempered glass
B. Plywood
C. Aluminum sheets
D. Asphalt
Rationale: Tempered glass is widely used due to its strength
and safety properties.
Correct Answer: A. Tempered glass
,3. What is the main safety feature of tempered glass?
A. It melts at low temperature
B. It shatters into large sharp pieces
C. It breaks into small, blunt granules
D. It cannot be cut
Rationale: Tempered glass is designed to break into small, less
dangerous pieces to reduce injury risk.
Correct Answer: C. It breaks into small, blunt granules
4. Laminated glass is primarily used for what purpose?
A. Increasing electrical conductivity
B. Improving sound insulation and safety
C. Reducing paint adhesion
D. Enhancing wood bonding
Rationale: Laminated glass holds together when broken,
improving safety and sound insulation.
Correct Answer: B. Improving sound insulation and safety
5. What tool is commonly used to cut glass sheets?
A. Hammer
B. Glass cutter
C. Wrench
D. Drill press
,Rationale: A glass cutter scores the surface so the glass can be

9. What is the purpose of a glazing bead?
A. To measure glass thickness
B. To hold glass securely in a frame
C. To paint window frames
D. To clean glass
Rationale: Glazing beads mechanically secure the glass in place.
Correct Answer: B. To hold glass securely in a frame
10. What is annealed glass?
A. Heat-treated safety glass
B. Standard float glass that has been slowly cooled
C. Reinforced plastic glass
D. Laminated safety glass
Rationale: Annealed glass is basic float glass cooled slowly to
relieve internal stresses.
