Certification Exam Practice Questions And Correct
Answers (100%Verified Answers) Plus Rationales
Q&A |
3. What is the purpose of a glazing bead in storefront systems?
a) Structural reinforcement
b) Secure the glass in the frame
c) Provide thermal insulation
d) Reduce sound transmission
Rationale: Glazing beads hold the glass securely within the frame
while allowing for adjustment and sealant application.
4. Which type of aluminum joint is typically used for expansion? a)
Butt joint
b) Welded corner
c) Slip joint
d) Miter joint
Rationale: Slip joints accommodate thermal expansion and
contraction without stressing the frame or glass.
5. What is the maximum recommended air infiltration rate for
commercial storefronts? a) 1.0 cfm/sf
, b) 2.0 cfm/sf
c) 0.3–0.5 cfm/sf
d) 5.0 cfm/sf
Rationale: Properly designed storefronts meet low air infiltration
rates to improve energy efficiency and occupant comfort.
6. Which tool is used to test the adhesion of structural silicone
sealants?
a) Screwdriver
b) Hammer
c) Peel or tensile adhesion tester
d) Tape measure
Rationale: Peel or tensile adhesion testers measure sealant bonding
strength to substrates, ensuring proper performance.
7. Which glazing method allows for a smooth, uninterrupted
exterior glass surface?
a) Stick-built curtain wall
b) Structural silicone glazing (SSG)
c) Storefront with cap beads
d) Window wall
Rationale: SSG adheres glass directly to frames, minimizing visible
framing for a sleek exterior appearance.
,8. What is the primary purpose of a sealant primer in structural
glazing?
a) Color matching
b) Improve adhesion to substrate
c) Thermal insulation
d) Reduce UV degradation
Rationale: Primers enhance the chemical bond between the sealant
and the substrate, improving longevity and performance.
9. Which component prevents water accumulation in a unitized
curtain wall?
a) Thermal break
b) Structural mullion
c) Internal drainage system
d) Pressure plate
Rationale: Drainage channels within unitized curtain walls guide
water safely out of the assembly.
10. Which fire-rated glazing type is used for vision panels in doors?
a) Tempered glass
b) Laminated glass
c) Wired or ceramic fire-rated glass
d) Reflective glass
Rationale: Fire-rated glass in doors provides limited-duration
protection while allowing visibility.
, 11. What is a common issue when using silicone over
noncompatible substrates?
a) Improved adhesion
b) Poor adhesion and potential joint failure
c) Increased thermal insulation
d) Color retention
Rationale: Incompatible substrates can prevent proper chemical
bonding, leading to joint failure.
12. Which aluminum alloy is commonly used for extrusions in
curtain walls? a) 2024
b) 6063
c) 7075
d) 5052
Rationale: 6063 aluminum offers excellent extrudability, corrosion
resistance, and strength suitable for architectural applications.
13. What is the recommended method to prevent glass from fogging
in IGUs?
a) Increase thickness
b) Use reflective coatings
c) Proper sealing and desiccant use
d) Apply tempering
Rationale: Effective edge seals and desiccants prevent moisture
ingress, eliminating fogging.
