1. What is the primary purpose of tempered glass in architectural
applications?
A. Improve insulation
B. Increase soundproofing
C. Improve safety by breaking into small pieces
D. Reduce glare
Rationale: Tempered glass is heat-treated to increase strength and to
break into small, less dangerous fragments for safety.
2. Laminated glass differs from tempered glass because it:
A. Is weaker
B. Contains an interlayer that holds fragments together
C. Cannot be cut
D. Is only decorative
Rationale: Laminated glass uses a plastic interlayer that retains shards
when broken, improving safety and security.
3. Which metal is most commonly used for curtain wall framing?
A. Steel
B. Copper
C. Aluminum
D. Brass
, Rationale: Aluminum is lightweight, corrosion-resistant, and easy to
fabricate, making it ideal for curtain walls.
4. What is the main function of a mullion in a curtain wall system?
A. Support flooring
B. Provide insulation
C. Separate and support glass panels
D. Act as a vapor barrier
Rationale: Mullions structurally support and divide glass units within
glazing systems.
5. IGU stands for:
A. Industrial Glass Unit
B. Insulated Glass Unit
C. Internal Glazing Unit
D. Integrated Glass Utility
Rationale: IGU refers to sealed multiple-pane glass units designed for
thermal performance.
6. What gas is commonly used between panes in an IGU to improve
insulation?
A. Oxygen
B. Argon
C. Nitrogen
D. Carbon dioxide
Rationale: Argon gas reduces heat transfer due to its low thermal
conductivity.
7. The primary purpose of Low-E coating is to:
A. Strengthen glass
B. Reduce heat transfer
C. Improve clarity
D. Prevent breakage
Rationale: Low-emissivity coatings reflect infrared energy, improving
thermal efficiency.
8. Which fastener is typically used for aluminum framing systems?
A. Wood screws
, B. Rivets only
C. Stainless steel screws
D. Nails
Rationale: Stainless steel screws provide corrosion resistance and strength
for aluminum assemblies.
9. What safety equipment is MOST critical when handling large glass panels?
A. Hard hat only
B. Steel boots only
C. Cut-resistant gloves and eye protection
D. Ear protection
Rationale: Gloves and eye protection reduce risk of lacerations and eye
injuries.
10.Shop drawings are used to:
A. Replace architectural drawings
B. Provide detailed fabrication and installation information
C. Show only elevations
D. Eliminate field measurements
Rationale: Shop drawings translate design intent into precise fabrication
details.
11.What tool is commonly used to cut glass?
A. Grinder
B. Glass cutter
C. Chisel
D. Saw
Rationale: Glass cutters score the surface, allowing controlled breakage.
12.What does thermal break refer to in aluminum systems?
A. Fire resistance
B. Structural separation
C. Insulating barrier between interior and exterior metal
D. Decorative feature
Rationale: Thermal breaks reduce heat transfer through metal frames.
13.Which glazing system relies on sealant instead of mechanical fasteners?
A. Punched window
