INTRODUCTION
The purpose of the Connecticut Glazing Contractor Exam is to validate the competency of professionals in
the glazing and glass installation trade. The exam assesses a candidate's knowledge of foundational
glazing theory, structural systems, and applied professional skills. It tests familiarity with building codes,
safety regulations, and legal compliance specific to Connecticut. The structure includes multiple-choice
and scenario-based questions, emphasizing real-world application, critical thinking, and ethical decision-
making. Success requires a comprehensive understanding of installation practices, project management,
and the professional standards necessary to protect public safety and ensure structural integrity in the
built environment.
SECTION ONE – QUESTIONS 1–100
Question 1
What is the primary purpose of a setting block in a glazing system?
A. To secure the glass to the frame
B. To provide a seal against water infiltration
C. To support the weight of the glass
D. To allow for thermal expansion
🟢 Correct answer: C
🔴 Explanation: Setting blocks are placed under the edge of the glass to bear its weight and prevent it
from resting directly on the frame, which could cause stress and breakage.
Question 2
A client wants to use a glass type that minimizes the risk of injury from breakage in a school
gymnasium. Which glass should be recommended?
A. Annealed glass
B. Heat-strengthened glass
C. Laminated glass
D. Tempered glass
,🟢 Correct answer: C
🔴 Explanation: Laminated glass is designed to hold together when broken, with the interlayer
preventing large shards from falling, making it a superior safety choice for locations where breakage is
a concern.
Question 3
Which document defines the specific quality standards and performance requirements for materials
and workmanship on a glazing project?
A. The shop drawing
B. The contract
C. The project specifications
D. The building code
🟢 Correct answer: C
🔴 Explanation: Project specifications, part of the contract documents, provide detailed technical
descriptions of materials, installation methods, and workmanship quality standards.
Question 4
What is the primary function of a weep system in a window frame?
A. To allow for thermal expansion of the glass
B. To drain water that has penetrated the glazing system
C. To provide ventilation for the building interior
D. To allow for structural movement
🟢 Correct answer: B
🔴 Explanation: Weep holes and baffles are part of a drainage system designed to collect and channel
water out of the frame, preventing moisture buildup and potential damage.
Question 5
A glazing contractor is asked to install a curtain wall on a high-rise building. What is the most critical
factor to consider for the structural silicone?
A. Its color
B. Its cure time
C. Its adhesion and compatibility with the substrates
D. Its cost
🟢 Correct answer: C
🔴 Explanation: Structural silicone's primary role is to transfer wind loads from the glass to the frame.
Proper adhesion to both the glass and the frame is critical for the safety and integrity of the entire
system.
Question 6
According to OSHA, what is the minimum required distance for a warning line from an unprotected
roof edge?
A. 5 feet
B. 6 feet
C. 10 feet
D. 15 feet
🟢 Correct answer: B
,🔴 Explanation: OSHA 29 CFR 1926.502(f)(2) requires that a warning line system be erected no less
than 6 feet from the unprotected edge of a roof.
Question 7
What is the purpose of a mock-up in a glazing project?
A. To test the final building performance
B. To provide a sample for the architect's color selection
C. To verify the constructability, performance, and aesthetics of the assembly
D. To train the installation crew
🟢 Correct answer: C
🔴 Explanation: A mock-up is a full-scale, representative sample of the final assembly, used to test and
verify performance criteria like water and air infiltration, structural integrity, and visual quality before
mass production and installation.
Question 8
A general contractor instructs a glazing subcontractor to proceed with an installation that deviates
from the approved shop drawings. What should the glazing contractor do?
A. Proceed as instructed to avoid conflict
B. Refuse to proceed and document the directive
C. Proceed but request a change order for the cost difference
D. Install it as directed and note it on the as-built drawings
🟢 Correct answer: B
🔴 Explanation: The glazing contractor is professionally and legally responsible for adhering to
approved plans. Installing a non-compliant system could create safety hazards and liability. The
directive should be refused and documented in writing.
Question 9
What is the primary difference between tempered and heat-strengthened glass?
A. Their color
B. The way they break and their relative strength
C. Their resistance to UV light
D. Their cost
🟢 Correct answer: B
🔴 Explanation: Tempered glass is about four times stronger than annealed glass and breaks into
small, granular pieces. Heat-strengthened glass is about twice as strong and breaks into larger, more
jagged shards similar to annealed glass.
Question 10
The term "bite" in glazing refers to:
A. The amount of sealant required for a watertight seal
B. The depth of the glass edge that is captured by the frame
C. The thickness of the glass pane
D. The pressure exerted by wind on the glass
🟢 Correct answer: B
🔴 Explanation: The "bite" or "edge clearance" is the distance the edge of the glass extends into the
frame's glazing pocket. It is critical for structural support and weather sealing.
, Question 11
Which type of glass is manufactured by cooling molten glass in a controlled process to induce
compressive stresses on its surface?
A. Annealed glass
B. Laminated glass
C. Tempered glass
D. Insulated glass
🟢 Correct answer: C
🔴 Explanation: Tempering is a process where annealed glass is reheated and then rapidly cooled,
creating a state of high surface compression and internal tension, which gives it its strength.
Question 12
A project requires a glazing system to meet a specific U-value. What does U-value measure?
A. The amount of solar heat gained through the glass
B. The rate of heat transfer through the glass
C. The amount of visible light transmitted through the glass
D. The structural strength of the glass
🟢 Correct answer: B
🔴 Explanation: U-value is a measure of thermal transmittance, or the rate at which heat flows through
a material. A lower U-value indicates better insulation.
Question 13
In a four-sided structurally glazed system, what provides the primary structural attachment of the glass
to the frame?
A. The setting blocks
B. The gaskets
C. The structural silicone sealant
D. The pressure plate
🟢 Correct answer: C
🔴 Explanation: In a four-sided structural glazing system, the glass is attached to the frame on all four
sides using structural silicone sealant, which transfers all wind and dead loads.
Question 14
What is a "shop drawing" in the context of a glazing project?
A. A preliminary sketch made on-site
B. A detailed drawing prepared by the contractor for fabrication and installation
C. A drawing showing the location of the project on a map
D. A drawing used for marketing purposes
🟢 Correct answer: B
🔴 Explanation: Shop drawings are detailed, project-specific drawings prepared by the contractor,
subcontractor, or manufacturer to show how the work will be fabricated and installed.
Question 15
A glazier is installing an insulated glass unit (IGU). What is the function of the desiccant in the spacer?
A. To strengthen the unit
B. To absorb moisture from the air space
C. To improve the U-value
