1. Which of the following is the primary reason for using tempered glass in
curtain wall applications?
a) Cost efficiency
b) Ease of cutting on site
c) Increased strength and safety
d) Aesthetic variety
Rationale: Tempered glass is heat-treated to improve strength and shatter
into small, less dangerous pieces upon breakage, making it safer for
architectural applications.
2. What is the main purpose of a structural silicone sealant in glass curtain
walls?
a) To add color to the facade
b) To provide weatherproofing and structural adhesion
c) To replace mechanical fasteners
d) To insulate thermal bridges
Rationale: Structural silicone sealants bond glass panels to metal frames
, and provide flexibility for thermal expansion while preventing water
infiltration.
3. Which metal is most commonly used for storefront framing due to its
corrosion resistance and finish quality?
a) Steel
b) Copper
c) Aluminum
d) Zinc
Rationale: Aluminum is lightweight, corrosion-resistant, and can be
anodized or painted for aesthetic finishes, making it ideal for storefronts.
4. Which type of glass is designed to reduce solar heat gain while maintaining
visible light transmission?
a) Laminated glass
b) Clear annealed glass
c) Low-E coated glass
d) Tempered glass
Rationale: Low-emissivity coatings reflect infrared heat while allowing
visible light, reducing solar heat gain without darkening the interior.
5. When installing a glass panel, what is the standard minimum edge
clearance from a fixed frame to prevent stress?
a) 1/16 inch
b) 1/4 inch
c) 1/8 inch
d) 3/8 inch
Rationale: A minimum 1/8 inch clearance allows for expansion,
contraction, and proper sealant coverage without inducing stress in the
glass.
6. What is the primary function of a pressure plate in a stick-built curtain wall
system?
a) Decorative finish
b) Thermal insulation
, c) To hold glass in place and transfer loads to the frame
d) To allow drainage of condensation
Rationale: Pressure plates clamp the glass panels securely to the mullions,
transferring wind and gravity loads while allowing sealant to function.
7. Which of the following is a key safety requirement when cutting glass on
site?
a) Working quickly to avoid delays
b) Using dull cutting wheels for controlled pressure
c) Wearing safety glasses and gloves
d) Cutting without support for efficiency
Rationale: Personal protective equipment (PPE) such as safety glasses and
gloves prevents injury from glass shards and cutting tools.
8. What is the recommended slope for metal flashing in storefront systems to
prevent water accumulation?
a) Flat (0°)
b) 1°
c) 1/4 inch per foot
d) 1 inch per foot
Rationale: A slope of 1/4 inch per foot ensures water drains away from
the system, preventing corrosion or leaks.
9. Which type of glazing is most effective at reducing sound transmission in
urban environments?
a) Single-pane clear glass
b) Tempered glass
c) Laminated glass with acoustic interlayer
d) Low-E glass
Rationale: Laminated glass with an acoustic interlayer dampens sound
vibrations, reducing exterior noise transmission.
10.In anodized aluminum finishes, what is the purpose of the anodizing
process?
a) To create a corrosion-resistant oxide layer
