Practice Question Bank & Answer Rationale
THIS PACK CONTAINS
150 exam-style multiple-choice questions. Each question includes the correct answer and a complete
rationale for focused revision.
COVERAGE
This practice exam covers the core competencies required for the Connecticut Glazier Journeyperson
certification, including safety regulations, glass handling, structural glazing, sealants, and blueprint reading. It
assesses both theoretical knowledge and practical application in commercial and residential glazing
scenarios.

,1. When installing a butt-glazed vertical joint using structural silicone, which factor most
directly determines the required sealant bite?
[ ] A. The color of the silicone
[ ] B. The wind load and glass thickness
[ ] C. The ambient temperature during installation
[ ] D. The brand of the sealant
CORRECT: B. The wind load and glass thickness
The sealant bite (contact width) is calculated based on the design wind load and the glass panel dimensions,
ensuring the structural silicone can transfer loads without exceeding its tensile strength. Color, temperature,
and brand affect cure and appearance but not the structural bite requirement.
2. A glazier is preparing to cut laminated glass with a PVB interlayer. Which tool is
specifically designed for this task?
[ ] A. Glass cutter with carbide wheel
[ ] B. Oil-filled glass cutter
[ ] C. Laminated glass cutter with reservoir
[ ] D. Diamond scribe
CORRECT: C. Laminated glass cutter with reservoir
Laminated glass requires a cutter with a reservoir that applies cutting oil to the wheel and often includes a
special mechanism to separate the interlayer. Standard glass cutters (A, B, D) are for monolithic glass and
will not effectively score laminated glass.
3. In curtain wall installation, what is the primary purpose of a pressure-equalized rain
screen design?
[ ] A. To eliminate the need for sealants
[ ] B. To reduce wind load on the glass
[ ] C. To prevent water infiltration by neutralizing pressure differences
[ ] D. To improve thermal insulation
CORRECT: C. To prevent water infiltration by neutralizing pressure differences
Pressure-equalized rain screens use baffled cavities to equalize pressure across the exterior and interior of
the wall, preventing water from being driven inward. They do not eliminate sealants, reduce wind load, or
primarily improve insulation.
4. Which type of glass must be used in a fire-rated door vision panel according to NFPA
80?
[ ] A. Tempered glass
[ ] B. Laminated glass
HIGHP - Page 2 of 47
, [ ] C. Fire-rated glazing labeled for the door assembly
[ ] D. Wired glass
CORRECT: C. Fire-rated glazing labeled for the door assembly
NFPA 80 requires fire-rated glazing that is specifically tested and labeled for use in fire door assemblies.
Tempered and laminated glass may not meet fire ratings, and wired glass is no longer automatically accepted
unless it meets current fire-rated glazing standards.
5. When reading a glazing schedule, the notation '1/4" CLR' typically indicates:
[ ] A. 1/4-inch clear tempered glass
[ ] B. 1/4-inch clear annealed glass
[ ] C. 1/4-inch clear laminated glass
[ ] D. 1/4-inch clear heat-strengthened glass
CORRECT: B. 1/4-inch clear annealed glass
In glazing schedules, 'CLR' stands for clear annealed glass unless otherwise specified. Tempered, laminated,
and heat-strengthened glass are typically denoted by 'TMP', 'LAM', or 'HS' respectively.
6. What is the minimum safety factor for temporary guardrails used during glazing
installation on a commercial project, per OSHA 1926 Subpart M?
[ ] A. 200 pounds
[ ] B. 500 pounds
[ ] C. 1,000 pounds
[ ] D. 2,000 pounds
CORRECT: A. 200 pounds
OSHA requires temporary guardrails to withstand a force of at least 200 pounds applied at any point along
the top rail. This is a minimum requirement for fall protection during construction.
7. Which sealant is most appropriate for glazing a mirror to a concrete wall in a
high-humidity environment?
[ ] A. Acrylic latex caulk
[ ] B. Silicone sealant
[ ] C. Butyl tape
[ ] D. Polyurethane sealant
CORRECT: B. Silicone sealant
Silicone sealant is non-corrosive, waterproof, and adheres well to glass and concrete, making it ideal for
high-humidity areas. Acrylic latex may not provide adequate adhesion or moisture resistance, butyl tape is
not typically used for mirrors, and polyurethane may not adhere to glass without a primer.

, 8. In structural glazing, what is the function of a 'setting block'?
[ ] A. To align the glass panel horizontally
[ ] B. To support the weight of the glass and prevent contact with the frame
[ ] C. To provide a seal against water infiltration
[ ] D. To act as a thermal break
CORRECT: B. To support the weight of the glass and prevent contact with the frame
Setting blocks are placed under the glass edge to support its weight and maintain a gap between the glass
and the frame, preventing stress and breakage. They do not align horizontally, seal, or insulate.
9. When installing an insulated glass unit (IGU) with a low-E coating, which surface should
the low-E coating face in a cold climate?
[ ] A. Surface 1 (exterior)
[ ] B. Surface 2 (interior of exterior pane)
[ ] C. Surface 3 (exterior of interior pane)
[ ] D. Surface 4 (interior)
CORRECT: B. Surface 2 (interior of exterior pane)
In cold climates, the low-E coating is typically placed on surface 2 to reflect heat back into the building while
allowing solar heat gain. Surface 1 would reflect solar heat away, surface 3 is used in warm climates, and
surface 4 is less effective.
10. What is the primary reason for using a 'dry glaze' system in storefront framing?
[ ] A. It allows for easier glass replacement
[ ] B. It provides superior waterproofing
[ ] C. It eliminates the need for gaskets
[ ] D. It reduces material cost
CORRECT: A. It allows for easier glass replacement
Dry glaze systems use gaskets and pressure plates that can be disassembled to replace glass without
removing the entire frame. They do not inherently provide better waterproofing, eliminate gaskets, or reduce
cost.
11. In a storefront system, the primary structural purpose of the horizontal mullion is to:
[ ] A. Provide a thermal break between interior and exterior.
[ ] B. Transfer wind load from the glass to the vertical mullions or building structure.
[ ] C. Serve as the primary drainage path for condensation.
[ ] D. Act as the fire-stop between floor slabs.
