1. Which type of glass is commonly used for exterior windows due to
its strength and safety characteristics?
a) Annealed glass
b) Tempered glass
c) Float glass
d) Wired glass
Tempered glass is heat-treated to increase strength and, if broken,
shatters into small, less harmful pieces, making it suitable for
exterior applications.
2. What is the primary purpose of a setting block in glazing?
a) Seal against moisture
b) Provide decorative spacing
c) Support the weight of the glass
d) Facilitate removal of glass
Setting blocks are typically made of neoprene or silicone and
positioned at the bottom of the frame to bear the glass weight
and prevent stress at the corners.
3. Which glazing compound is commonly used for exterior wood
frames?
a) Silicone sealant
, b) Linseed oil-based putty
c) Acrylic caulk
d) Epoxy resin
Linseed oil-based putty adheres well to wood, remains flexible, and
provides a weatherproof seal.
4. Laminated glass is primarily designed for:
a) Thermal insulation
b) Safety and security
c) Acoustic reduction only
d) Decorative purposes
Laminated glass consists of two or more glass layers with an
interlayer, which holds fragments together if broken, enhancing
safety and security.
5. Which of the following is a characteristic of annealed glass?
a) Breaks into small, blunt pieces
b) Breaks into large, sharp shards
c) Cannot be cut
d) Is used for tempered applications
Annealed glass is standard float glass that has not been heat-
treated, so it breaks into large, sharp pieces.
6. For insulating glass units (IGUs), the spacer bar is used to:
a) Strengthen the frame
b) Separate the glass panes and maintain a seal
c) Provide a decorative finish
d) Allow ventilation
The spacer bar separates the panes of glass and is filled with
desiccant to prevent condensation inside the unit.
, 7. Which safety equipment is essential when cutting glass?
a) Safety glasses and gloves
b) Ear plugs
c) Welding mask
d) Respirator
Cutting glass produces sharp shards, so eye and hand protection
are critical.
8. What is the minimum thickness of tempered glass for a residential
door?
a) 4 mm
b) 5 mm
c) 6 mm
d) 8 mm
Building codes generally require a minimum of 6 mm tempered
glass for residential doors to ensure adequate strength.
9. The primary advantage of low-emissivity (Low-E) glass is:
a) Increased impact resistance
b) Improved energy efficiency
c) Enhanced transparency
d) Scratch resistance
Low-E coatings reflect infrared energy, reducing heat transfer and
improving energy efficiency.
10. When measuring a frame for glass installation, the
measurement should be:
a) Exact frame size
b) Frame size minus 3 mm
c) Frame size plus 3 mm
