1. What is the primary purpose of architectural glazing in modern construction?
A. To increase structural steel strength
B. To provide natural light, weather protection, and aesthetic enhancement
C. To replace load-bearing walls entirely
D. To eliminate the need for HVAC systems
CORRECT ANSWER: B. To provide natural light, weather protection, and aesthetic
enhancement
RATIONALE: Architectural glazing systems are designed to improve daylighting, energy
efficiency, and building appearance while protecting interiors from environmental elements.
2. Which material is most commonly used for structural framing in curtain wall systems?
A. PVC
B. Aluminum
C. Gypsum
D. Wood
CORRECT ANSWER: B. Aluminum
RATIONALE: Aluminum is widely used due to its strength-to-weight ratio, corrosion resistance,
and ease of fabrication.
3. What is the primary function of a curtain wall system?
A. Load-bearing structural support
B. Non-structural exterior enclosure
,C. Electrical distribution
D. Plumbing support system
CORRECT ANSWER: B. Non-structural exterior enclosure
RATIONALE: Curtain walls are non-load-bearing systems designed to resist air and water
infiltration while transferring wind loads to the structure.
4. Which type of glass is designed to reduce injury risk by breaking into small granular
pieces?
A. Annealed glass
B. Laminated glass
C. Tempered glass
D. Wired glass
CORRECT ANSWER: C. Tempered glass
RATIONALE: Tempered glass is heat-treated to increase strength and, when broken, shatters
into small blunt fragments to reduce injury risk.
5. Laminated glass is primarily used for:
A. Decorative flooring only
B. Improved security and safety performance
C. Electrical insulation
D. Structural steel replacement
CORRECT ANSWER: B. Improved security and safety performance
RATIONALE: Laminated glass holds together when broken due to an interlayer, improving
safety, security, and sound control.
6. What is the purpose of a thermal break in aluminum framing systems?
A. Increase electrical conductivity
B. Reduce heat transfer through framing members
C. Improve glass transparency
D. Strengthen structural load capacity only
, CORRECT ANSWER: B. Reduce heat transfer through framing members
RATIONALE: Thermal breaks reduce thermal bridging, improving energy efficiency and
condensation resistance.
7. Which sealant property is most critical for glazing applications exposed to weather?
A. Color brightness
B. UV and weather resistance
C. Electrical conductivity
D. Magnetic strength
CORRECT ANSWER: B. UV and weather resistance
RATIONALE: Sealants must withstand sunlight, moisture, and temperature changes without
degrading.
8. What is the primary purpose of glazing gaskets?
A. Provide electrical grounding
B. Hold glass in place and provide weather seal
C. Increase glass transparency
D. Replace framing members
CORRECT ANSWER: B. Hold glass in place and provide weather seal
RATIONALE: Gaskets secure glass panels and prevent air and water infiltration.
9. Insulated glass units (IGUs) are primarily used to:
A. Increase building weight
B. Improve thermal insulation and energy efficiency
C. Replace structural steel
D. Conduct electricity
CORRECT ANSWER: B. Improve thermal insulation and energy efficiency
RATIONALE: IGUs consist of multiple glass panes separated by spacers to reduce heat transfer.
