CR-65 Glazing Contractor Exam 2026 – 200+ Practice
Q&As with Rationales | Pass Arizona ROC License
Question 1. Which type of glass is specifically designed to break into small,
granular pieces when fractured, making it safer for use in doors and windows?
A. Annealed glass
B. Tempered glass
C. Laminated glass
D. Wired glass
Correct Answer: B
Rationale:
Tempered glass is processed through controlled thermal or chemical treatments that
create internal stresses. When broken, it disintegrates into small, relatively harmless
granular chunks instead of jagged shards. Annealed glass (A) breaks into large, sharp
shards. Laminated glass (C) holds together when broken due to a plastic interlayer.
Wired glass (D) contains a wire mesh but still breaks into sharp pieces.
Question 2. In Arizona, under the ROC (Registrar of Contractors) rules, what is the
maximum contract amount a CR-65 Glazing Contractor can perform without a
license?
A. $1,000
B. $500
C. $750
D. $2,000
Correct Answer: B
Rationale:
Arizona Revised Statutes §32-1121 states that a person may not act as a contractor
,without a license if the total contract price is $1,000 or more (or $500 for electrical,
plumbing, air conditioning, and glazing). For glazing contractors, the threshold is $500.
Therefore, any project $500 or more requires a CR-65 license. Options A, C, and D are
incorrect thresholds.
Question 3. What is the primary function of a "setting block" in glazing
installation?
A. To hold the glass in place during installation
B. To support the weight of the glass and prevent it from resting directly on the frame
C. To seal the edges of the glass
D. To provide thermal insulation
Correct Answer: B
Rationale:
Setting blocks are small, hard rubber or plastic blocks placed under the bottom edge of
the glass to support its weight. They prevent the glass from contacting the frame
directly, which could cause stress cracks or breakage, and allow for drainage and
expansion. They do not primarily hold the glass in place (that's the glazing bead), seal
edges (that's sealant), or insulate (that's the glass unit itself).
Question 4. Which of the following is NOT a common type of glazing system?
A. Curtain wall
B. Storefront
C. Window wall
D. Load-bearing masonry
Correct Answer: D
Rationale:
Curtain wall (A), storefront (B), and window wall (C) are all common glazing systems
,used to enclose buildings with glass and metal framing. Load-bearing masonry (D) is a
structural system where walls support loads, not a glazing system.
Question 5. What does the term "U-value" refer to in glazing?
A. The amount of heat transferred through the glass
B. The amount of light transmitted through the glass
C. The strength of the glass
D. The thickness of the glass
Correct Answer: A
Rationale:
U-value (or U-factor) measures the rate of heat transfer through a material. In glazing, a
lower U-value indicates better insulation (less heat loss/gain). Visible light transmission
(B) is measured by VLT. Strength (C) is measured by various tests. Thickness (D) is a
physical dimension.
Question 6. Which of the following glass types is made by bonding two or more
layers of glass with a plastic interlayer?
A. Tempered glass
B. Laminated glass
C. Insulated glass
D. Heat-strengthened glass
Correct Answer: B
Rationale:
Laminated glass consists of two or more panes of glass bonded together with a plastic
interlayer (typically PVB or SGP). When broken, the fragments adhere to the interlayer,
reducing the risk of injury. Tempered glass (A) is heat-treated. Insulated glass (C) is a
unit with two panes separated by a spacer. Heat-strengthened glass (D) is partially
tempered.
, Question 7. In Arizona, what is the minimum glazing contractor license
classification required for a project involving the installation of a storefront
system valued at $10,000?
A. CR-65
B. CR-66
C. CR-67
D. No license required
Correct Answer: A
Rationale:
The CR-65 license is specifically for glazing contractors. Any glazing project over $500
requires a CR-65 license. Since the project is $10,000, a CR-65 license is required. CR-66
and CR-67 are other specialty classifications (e.g., CR-66 is for swimming pools, CR-67 is
for drywall). No license is incorrect.
Question 8. What is the purpose of a "weep hole" in a glazing system?
A. To allow water to drain from the glazing channel
B. To allow air to escape during installation
C. To provide ventilation for the building
D. To allow for thermal expansion of the glass
Correct Answer: A
Rationale:
Weep holes are small openings in the glazing frame that allow water that has
penetrated the system to drain out, preventing water accumulation and potential
damage. They do not primarily allow air to escape (B), ventilate the building (C), or
accommodate thermal expansion (D) (that's expansion joints).
Question 9. Which of the following is a safety glazing material as defined by the
Consumer Product Safety Commission (CPSC) and required by building codes?
