Architectural Glass & Metal Technician (AGMT) Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• 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.

• Which type of glass is most commonly used in high-rise curtain walls

for safety? 1 / 4

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.

• 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.

• 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 2 / 4

d) To increase structural strength

Rationale: Pressure-equalized systems use compartments to balance

pressure and prevent water from being driven into the wall system.

• Which alloy is commonly used for architectural aluminum framing due

to its strength and corrosion resistance?

• 6061
• 6063
• 7075
• 5052

Rationale: 6063 aluminum alloy is widely used in architectural

applications because it balances extrudability, strength, and corrosion resistance.

• 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.

• What is a common material used for structural silicone glazing (SSG)

sealants?

a) Polyurethane 3 / 4

b) Silicone

c) Acrylic

d) Butyl

Rationale: Silicone sealants are flexible, durable, and UV-resistant,

making them ideal for structural glazing applications.

• 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.

• 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.

• Which safety measure is required when handling large glass

panels on-site?

a) Only wear gloves

b) Only wear a hard hat
