1. What is the primary purpose of a thermal break in aluminum
framing systems?
a) To improve structural strength
b) To reduce heat transfer
c) To simplify installation
d) To prevent corrosion
Thermal breaks are insulating materials inserted into metal frames
to reduce heat transfer between interior and exterior surfaces.
2. Which of the following glass types is most effective at blocking UV
radiation?
a) Annealed glass
b) Laminated glass
c) Tempered glass
d) Float glass
Laminated glass contains a plastic interlayer that blocks most UV
radiation, protecting interior materials.
3. What is the minimum thickness of safety glazing required in doors
and adjacent panels?
a) 3 mm
b) 6 mm
, c) 10 mm
d) 12 mm
Safety glazing must meet building codes, which typically require a
minimum thickness of 6 mm to prevent injury upon breakage.
4. In curtain wall construction, what is the purpose of a mullion?
a) To secure glazing clips
b) To support and divide glazing panels
c) To seal joints
d) To attach weatherstripping
Mullions are vertical or horizontal framing members that provide
structural support and segment the glass panels.
5. Which sealant is most commonly used for exterior glazing in
commercial buildings?
a) Acrylic
b) Silicone
c) Polyurethane
d) Epoxy
Silicone sealants are flexible, durable, and resistant to UV, making
them ideal for exterior glazing.
6. What is the standard method to measure the deflection of a
storefront frame under load?
a) Visual inspection
b) Dial gauge or laser measurement
c) Tape measure
d) Thermal imaging
Deflection is measured precisely using dial gauges or laser tools to
ensure compliance with structural performance specifications.
, 7. Which glass type is heat-treated to increase strength and safety?
a) Laminated glass
b) Annealed glass
c) Tempered glass
d) Patterned glass
Tempered glass is heat-treated to become stronger and break into
small, blunt pieces if shattered.
8. What is the primary function of a pressure-equalized rain screen
system?
a) To improve structural support
b) To prevent water infiltration
c) To enhance sound insulation
d) To reduce condensation
Pressure-equalized systems allow water to drain and prevent it
from entering the building envelope.
9. Which fastener is commonly used to secure aluminum panels to
subframes?
a) Nails
b) Self-tapping screws
c) Epoxy
d) Staples
Self-tapping screws are used for metal-to-metal connections
because they cut threads as they are installed.
10. What does the term “annealing” refer to in glass fabrication?
a) Cutting glass
b) Controlled cooling to relieve stress
c) Coating for UV protection
