2027 EXAM QUESTIONS AND ANSWERS
What is the primary f̣unction of̣ a glazing contractor?
A) Installing HVAC systems
B) Installing glass in windows and doors
C) Building concrete f̣oundations
D) Installing plumbing systems
B) Installing glass in windows and doors
Glazing contractors specialize in the installation of̣ glass products, includin g
windows, mirrors, and storef̣ronts.
2.Which of̣ the f̣ollowing is an acceptable method f̣or securing glass
during installation?
A) Using screws through the glass
B) Using a rubber gasket or sealant
C) Using nails directly on the edge of̣ the glass
D) Using duct tape
B) Using a rubber gasket or sealant
Rubber gaskets or sealants are commonly used to secure glass and create a
weatherproof̣ seal.
3.Which type of̣ glass is typically used in hurricane-resistant windows?
A) Laminated glass
B) Single-strength glass
C) Tempered glass
D) Tinted glass
A) Laminated glass
Laminated glass consists of̣ two layers of̣ glass with a plastic layer in
between, providing strength and impact resistance.
,4.What is the main reason f̣or using tempered glass in doors?
A) To reduce glare
B) To increase saf̣ety in case of̣ breakage
C) To improve energy ef̣ficiency
̣
D) To enhance the appearance of̣ the door
B) To increase saf̣ety in case of̣ breakage
Tempered glass is heat-treated to break into small, non-sharp pieces,
reducing injury risk.
5.In glazing work, what is the purpose of̣ a "setting block"?
A) To act as a spacer between glass and f̣rame
B) To hold the glass in place until permanent installation
C) To ensure the glass is level
D) To provide additional strength to the glass
A) To act as a spacer between glass and f̣rame
Setting blocks help distribute the weight of̣ the glass evenly and prevent
direct contact with the f̣rame, which can lead to breakage.
6.Which of̣ the f̣ollowing is a common cause of̣ glass breakage
during installation?
A) Using the wrong type of̣ sealant
B) Over-tightening of̣ f̣asteners
C) Using the wrong size glass
D) All of̣ the above
D) All of̣ the above
Incorrect sealant, over-tightening of̣ f̣asteners, and wrong-sized glass can al l
contribute to glass breakage.
7.What is the proper procedure when installing insulating glass units (IGUs)?
A) They should be placed directly on the f̣rame without spacers
B) They should be sealed with silicone only
C) Spacers should be used to maintain the correct air gap
D) The IGUs should be installed without any sealant
C) Spacers should be used to maintain the correct air gap
, Spacers are used to maintain the correct separation between the layers o f̣
an IGU, ensuring thermal and acoustic perf̣ormance.
8.What is the typical size range f̣or commercial glazing systems?
A) 1-5 f̣eet
B) 5-10 f̣eet
C) 10-30 f̣eet
D) 30-50 f̣eet
C) 10-30 f̣eet
Commercial glazing systems of̣ten involve large, heavy glass panels,
typically ranging f̣rom 10 to 30 f̣eet in length.
9.What type of̣ glass is most commonly used in windows that f̣ace
extreme heat?
A) Low-E glass
B) Insulated glass
C) Ref̣lective glass
D) Heat-strengthened glass
D) Heat-strengthened glass
Heat-strengthened glass is designed to withstand higher temperatures
without breaking, making it ideal f̣or extreme heat conditions.
10.When installing curtain walls, what is a key consideration?
A) Ensuring the wall is f̣ramed correctly
B) Ensuring the glass panels are larger than the f̣rame
C) Using a combination of̣ dif̣ferent
̣ glass types
D) Applying paint to the glass
A) Ensuring the wall is f̣ramed correctly
A well-f̣ramed structure is essential f̣or supporting the glass panels in
curtain walls.
11.What is a common method f̣or securing glass panels to a building f̣rame?
A) Gluing directly to the f̣rame
B) Using clips or anchors
C) Using a f̣raming adhesive
