Questions And Correct Answers With
Rationales 2026
1. What is the primary purpose of a structural glazing system?
a) To increase thermal insulation
b) To support glass panels without visible framing
c) To reduce sound transmission
d) To prevent condensation
Rationale: Structural glazing systems are designed to support glass
panels using adhesives or hidden framing, creating a clean, frameless
appearance.
2. Which type of glass is most commonly used in high-rise curtain walls
for safety?
, a) Annealed glass
b) Tempered glass
c) Wired glass
d) Laminated glass
Rationale: Tempered glass is heat-strengthened to resist impact and
break into small, less dangerous pieces, making it ideal for safety in
high-rise applications.
3. What is the main difference between laminated glass and tempered
glass?
a) Laminated glass is stronger than tempered glass
b) Laminated glass consists of two or more layers bonded with an
interlayer
c) Tempered glass has an interlayer for safety
d) Tempered glass is used only for decorative purposes
Rationale: Laminated glass is made of multiple glass layers with a
plastic interlayer that holds shards together upon breakage, whereas
tempered glass is heat-treated for strength.
4. In curtain wall design, what is the purpose of a pressure-equalized
system?
a) To allow natural ventilation
b) To minimize water infiltration by equalizing pressure across the
wall
c) To improve thermal insulation
, d) To increase structural strength
Rationale: Pressure-equalized systems use compartments to balance
pressure and prevent water from being driven into the wall system.
5. Which alloy is commonly used for architectural aluminum framing due
to its strength and corrosion resistance?
a) 6061
b) 6063
c) 7075
d) 5052
Rationale: 6063 aluminum alloy is widely used in architectural
applications because it balances extrudability, strength, and
corrosion resistance.
6. What is the main advantage of insulated glass units (IGUs)?
a) Increased impact resistance
b) Reduced glare
c) Improved thermal performance
d) Noise absorption
Rationale: IGUs consist of two or more glass panes separated by a
spacer and sealed, providing superior thermal insulation compared
to single-pane glass.
7. What is a common material used for structural silicone glazing (SSG)
sealants?
a) Polyurethane
, b) Silicone
c) Acrylic
d) Butyl
Rationale: Silicone sealants are flexible, durable, and UV-resistant,
making them ideal for structural glazing applications.
8. Which glass type is used to block most ultraviolet (UV) radiation?
a) Clear annealed glass
b) Laminated glass with PVB interlayer
c) Tempered glass
d) Wired glass
Rationale: PVB interlayers in laminated glass absorb and block UV
radiation, protecting interiors and furnishings.
9. What is the primary function of a thermal break in aluminum framing?
a) Increase structural rigidity
b) Reduce sound transmission
c) Prevent heat transfer through the metal
d) Facilitate water drainage
Rationale: Thermal breaks are insulating materials inserted in metal
frames to reduce conduction and improve energy efficiency.
10. Which safety measure is required when handling large glass
panels on-site?
a) Only wear gloves
b) Only wear a hard hat
