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 undergoes a heat-treatment process that causes it to break into
small, blunt fragments rather than sharp shards. This significantly reduces the risk of serious
injury, making it suitable for safety-critical applications.
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 produces a precise score line on the surface of annealed glass,
allowing it to break cleanly and accurately along the intended line.
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 how much heat passes through a glazing system. Lower U-
values indicate better insulating performance and reduced heat loss or gain.
,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 contains an interlayer that holds the glass together when broken,
enhancing safety, security, and impact resistance.
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 the
preferred material for storefront framing systems.
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, absorb minor movements, and create a seal
that prevents air and water infiltration.
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 are designed to grip concrete securely, providing the strength
and reliability required for curtain wall attachments.
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 accumulated moisture to drain from framing systems,
preventing water damage, corrosion, and deterioration.
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: Building codes require safety glazing in hazardous locations, such as doors and
areas near walking surfaces, to reduce injury risk.
Which personal protective equipment 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: Cutting glass poses significant risks of lacerations and eye injuries, making gloves
and eye protection essential.
What most often causes glass edge failure?
A. UV exposure
B. Improper edge finishing
, C. Excessive tinting
D. Low humidity
Correct Answer: B
Rationale: Poorly finished glass edges can contain micro-cracks that propagate under stress,
leading to sudden failure.
What does the term “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 exact dimensions, materials, and installation details
required for fabrication and construction.
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 (low emissivity) coatings reflect infrared radiation while allowing visible
light to pass, reducing heat transfer into the building.
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
Correct Answer: C
Rationale: Expansion joints accommodate thermal movement caused by temperature
changes, preventing stress buildup, distortion, and structural damage.
