BUILDING TECHNOLOGY FINAL EXAM
QUESTIONS WITH CORRECT ANSWERS
What are the advantages of float glass over Plate glass? - CORRECT
| | | | | | | | | | | |
ANSWER✔✔-Float glass has higher optical quality, high finish quality, | | | | | | | | |
due to the molten tin mold process the glass does not need to be
| | | | | | | | | | | | | |
polished with abrasives (therefore less labor intensive).
| | | | | |
What is the proper terminology associated with the installation of glass
| | | | | | | | | | |
in an opening or to the material itself? What are individual pieces of
| | | | | | | | | | | | |
glass called (spelling is important)? - CORRECT ANSWER✔✔-Glazing -
| | | | | | | | |
installation/material
Lites - individual pieces
| | |
National Glazing Association 2020 Top Manufacturers
| | | | |
Thickness of Glass - CORRECT ANSWER✔✔-Determined by lite size and
| | | | | | | | | |
wind load |
Annealed glass - CORRECT ANSWER✔✔-A glass that is cooled slowly to
| | | | | | | | | | |
relieve internal stresses.
| |
, Heat-treated Glass - CORRECT ANSWER✔✔-Produced by reheating
| | | | | | |
annealed glass |
Cooling both surfaced rapidly with air
| | | | |
Creates compressive stress on face and edges while tensile stresses are
| | | | | | | | | | |
created in the core | | |
tempered glass- heat treated glass - CORRECT ANSWER✔✔-•Has high
| | | | | | | | |
strength qualities |
•Breaks into small squared-edges (not sharp-edged pieces)
| | | | | |
Name two situations in which you might use tempered glass? -
| | | | | | | | | | |
CORRECT ANSWER✔✔-Safety Glazing in places with potential for
| | | | | | | |
occupant impact |
Glass Doors with no framing
| | | |
Sports applications (squash, handball, basketball, hockey)
| | | | |
Laminated glass - CORRECT ANSWER✔✔-•Bonded to Polyvinyl Butyral
| | | | | | | |
Interlayer between two sheets of glass
| | | | |
•Held together if broken by the interlayer
| | | | | |
•May be colored or patterned
| | | |
•Good sound barrier compared to solid glass
| | | | | |
•Blocks most Ultra Violet light
| | | |
•Can contribute to lower Damage Weighted Transmittance (Tdw 1-0)
| | | | | | | |
