Certification Exam Practice Questions And Correct
Answers (100%Verified Answers) Plus Rationales
Q&A |
3. What is the purpose of a thermal spacer in an IGU?
a) Increase load resistance
b) Reduce sound
c) Minimize heat transfer at the glass edges
d) Prevent condensation only
Rationale: Thermal spacers reduce thermal bridging at the edges,
improving overall energy performance.
4. Which type of silicone is recommended for structural glazing?
a) Acetoxy
b) Neutral cure
c) Oxime
d) Polyurethane
Rationale: Neutral cure silicones are compatible with metals and
glass, providing long-term adhesion without corrosion risk.
5. What is the main purpose of a drip cap above a storefront
window?
, a) Aesthetic enhancement
b) Divert water away from the window
c) Improve structural strength
d) Reduce sound transmission
Rationale: Drip caps prevent water from running down the window
face and entering the assembly.
6. Which material is commonly used for fire-rated glazing
interlayers?
a) Polyurethane
b) Silicone
c) Intumescent layers or special ceramic interlayers
d) PVC
Rationale: Intumescent or ceramic interlayers expand or resist heat
to provide fire protection.
7. What is the standard tempering requirement for glass thickness
1/4 inch (6 mm) for safety applications? a) No tempering needed
b) Must be fully tempered
c) Laminated only
d) Heat-strengthened only
Rationale: 1/4-inch glass for safety applications must be tempered to
meet safety standards.
,8. Which glazing system allows for easy replacement of glass
panels without dismantling the frame? a) Stick-built curtain wall
b) Storefront with embedded mullions
c) Unitized curtain wall
d) Fixed window
Rationale: Unitized systems are pre-assembled, allowing glass
replacement with minimal disturbance to the rest of the structure.
9. Which factor most affects sealant joint movement capability? a)
Joint color
b) Sealant thickness only
c) Type of sealant and substrate compatibility
d) Joint length only
Rationale: Sealant formulation and substrate adhesion govern
flexibility and ability to handle joint movement.
10. What is the purpose of a desiccant in an IGU spacer?
a) Provide structural support
b) Absorb moisture to prevent condensation
c) Improve thermal performance
d) Reduce sound transmission
Rationale: Desiccants inside spacers absorb any trapped moisture,
preventing fogging or condensation inside the IGU.
, 11. Which type of aluminum joinery provides the strongest corner
connection? a) Butt joint
b) Miter with mechanical reinforcement
c) Welded corner only
d) Butt with silicone
Rationale: Mitered corners reinforced mechanically or welded
provide superior structural integrity in frames.
12. What is the recommended slope for a sill in storefront systems?
a) Horizontal
b) 1/16 inch per foot
c) 1/4 inch per foot or more
d) Vertical
Rationale: A slope of at least 1/4 inch per foot ensures proper
drainage of water away from the frame.
13. Which type of glass coating reduces solar heat gain but allows
visible light transmission?
a) Clear annealed glass
b) Mirror coating
c) Low-E coating
d) Frosted coating
Rationale: Low-E coatings reflect infrared energy while allowing
visible light, improving energy efficiency without darkening interiors.
