Questions with Correct Answers & Rationales WITH
VERIFIED SOLUTIONS GRADE A+.
1. What is the primary purpose of tempered glass in architectural
applications?
A. To reduce cost
B. To increase thermal insulation
C. To improve safety by breaking into small pieces
D. To enhance color appearance
Correct Answer: C
Rationale: Tempered glass is heat-treated so that when it breaks, it shatters
into small, relatively harmless pieces, reducing the risk of serious injury.
2. Which tool is MOST commonly used to score annealed glass?
A. Diamond saw
B. Glass cutter
C. Angle grinder
D. Circular saw
Correct Answer: B
Rationale: A glass cutter creates a controlled score line that allows the glass
to be broken cleanly along the desired edge.
3. What does the term “U-value” refer to in glazing systems?
A. Solar reflectance
B. Sound transmission
C. Thermal transmittance
D. Glass thickness
,Correct Answer: C
Rationale: U-value measures the rate of heat transfer through a glazing
system; lower values indicate better insulation performance.
4. Laminated glass is primarily used for which reason?
A. Decorative appearance
B. Impact resistance and safety
C. Ease of cutting
D. Reduced glare
Correct Answer: B
Rationale: Laminated glass holds together when broken due to an interlayer,
providing enhanced safety and security.
5. Which metal is MOST commonly used for storefront framing systems?
A. Steel
B. Brass
C. Aluminum
D. Copper
Correct Answer: C
Rationale: Aluminum is lightweight, corrosion-resistant, and easy to
fabricate, making it ideal for storefront systems.
6. What is the purpose of glazing gaskets?
A. Improve aesthetics only
B. Provide structural load support
C. Cushion glass and create a weather seal
D. Increase glass thickness
Correct Answer: C
Rationale: Glazing gaskets protect glass edges and prevent air and water
infiltration.
7. Which fastener is typically used to anchor curtain wall systems to concrete?
,A. Wood screws
B. Plastic anchors
C. Expansion anchors
D. Drywall screws
Correct Answer: C
Rationale: Expansion anchors provide strong, secure attachment to concrete
substrates.
8. What is the main function of weep holes in metal framing systems?
A. Improve insulation
B. Allow for expansion
C. Drain water from the system
D. Secure glazing beads
Correct Answer: C
Rationale: Weep holes allow trapped moisture to escape, preventing water
damage and corrosion.
9. Safety glazing is REQUIRED in which location?
A. Above suspended ceilings
B. Near floor-level doors
C. In mechanical rooms only
D. Behind wall panels
Correct Answer: B
Rationale: Safety glazing is required in hazardous locations such as doors
and areas near walking surfaces.
10. Which PPE is MOST critical when cutting glass?
A. Ear protection
B. Steel-toe boots
C. Cut-resistant gloves and eye protection
D. Hard hat only
Correct Answer: C
Rationale: Glass cutting presents high risk of lacerations and eye injuries,
making gloves and eye protection essential.
, 11. What causes glass edge failure most often?
A. UV exposure
B. Improper edge finishing
C. Excessive tinting
D. Low humidity
Correct Answer: B
Rationale: Poorly finished edges can develop micro-cracks that lead to
breakage under stress.
12. What does “shop drawing” refer to?
A. Architectural concept sketch
B. Field installation photos
C. Detailed fabrication and installation drawings
D. Material safety data sheets
Correct Answer: C
Rationale: Shop drawings provide precise dimensions and details needed for
fabrication and installation.
13. Which glazing type reduces solar heat gain most effectively?
A. Clear glass
B. Annealed glass
C. Low-E coated glass
D. Wired glass
Correct Answer: C
Rationale: Low-E coatings reflect infrared energy, reducing heat transfer into
the building.
14. What is the primary purpose of expansion joints in metal systems?
A. Improve appearance
B. Reduce installation time
C. Allow movement due to temperature changes
D. Increase structural strength
