Question 1
What is the primary purpose of glazing in building construction?
A. Structural framing
B. Thermal insulation only
C. Allowing light transmission and environmental separation
D. Electrical grounding
Correct Answer: C
Glazing refers to the installation of glass or transparent materials in building
openings such as windows, doors, and curtain walls. Its main purpose is to allow
natural light into a structure while providing a barrier against weather, wind,
and environmental conditions. While glazing can contribute to insulation and
aesthetics, its fundamental function is environmental separation and light
transmission.
Question 2
Which tool is most commonly used to cut glass sheets?
A. Hacksaw
B. Glass cutter
,C. Circular saw
D. Chisel
Correct Answer: B
A glass cutter uses a hardened wheel to score the surface of glass, creating a
controlled fracture line. Once scored, pressure is applied to snap the glass
cleanly along the score. Other tools are unsuitable because they either damage
the glass or lack precision.
Question 3
What type of glass is designed to break into small, relatively harmless pieces?
A. Laminated glass
B. Tempered glass
C. Annealed glass
D. Wired glass
Correct Answer: B
Tempered glass is heat-treated to increase strength. When broken, it shatters
into small granular pieces rather than sharp shards, reducing injury risk. This
makes it ideal for doors, shower enclosures, and safety applications.
Question 4
What is the primary function of glazing sealant?
A. Increase glass color
B. Prevent water and air infiltration
C. Strengthen steel frames
D. Conduct electricity
Correct Answer: B
Sealants create a weather-tight barrier between glass and framing materials.
They prevent moisture, air leakage, and thermal transfer, which improves
energy efficiency and protects structural components from water damage.
,Question 5
Which code is most commonly referenced for building standards in Connecticut?
A. OSHA 1910
B. International Building Code (IBC)
C. NFPA 70E
D. ANSI Z87.1
Correct Answer: B
The International Building Code (IBC) is widely adopted in Connecticut for
structural, fire safety, and building envelope requirements, including glazing
systems. It provides standardized regulations for safe construction practices.
Question 6
What is the purpose of laminated glass?
A. To increase conductivity
B. To reduce weight
C. To hold shards together when broken
D. To improve color clarity
Correct Answer: C
Laminated glass consists of two or more glass layers bonded with an interlayer
(usually PVB). When broken, the interlayer holds fragments in place, enhancing
safety and security.
Question 7
Which material is commonly used as a spacer in insulated glass units (IGUs)?
A. Wood
B. Aluminum
, C. Concrete
D. Copper
Correct Answer: B
Aluminum spacers are widely used in IGUs to separate panes of glass while
maintaining structural integrity and housing desiccants that reduce internal
condensation.
Question 8
What is the primary cause of thermal stress cracking in glass?
A. Electrical current
B. Uneven temperature distribution
C. Excessive polishing
D. Improper framing color
Correct Answer: B
Thermal stress occurs when different parts of a glass pane heat or cool at
different rates, causing internal tension that may result in cracking.
Question 9
What is the standard safety practice when handling large glass panels?
A. Work alone for speed
B. Wear gloves and use suction lifters
C. Use bare hands for better grip
D. Drag glass across surfaces
Correct Answer: B
Gloves protect against cuts, and suction lifters provide secure handling of large
or heavy glass panels, reducing breakage and injury risk.
