GLASS AND GLAZING

Question 1

– a hard brittle inorganic
substance, ordinarily transparent or
translucent

Answer 1

glass

Question 2

; produced by melting a
mixture of__, __, __; while molten, may be blown, drawn, rolled, pressed or
cast to a variety of shapes.

Answer 2

silica, a flux and a
stabilizer

Question 3

• the action, process, or
  trade of fitting windows with glass.

Answer 3

glass

Question 4

GLASS TYPE ACCORDING TO
MANNER OF MANUFACTURING

Answer 4

annealed glass
heat strengthened glass
tempered or toughened glass
laminated glass

Question 5

offers many advantages. Safety
and security are the best known of
these, so rather than shattering on
impact, __ is held together by the interlayer

Answer 5

laminated glass

Question 6

• this is the most common
  type of glass used in balustrades or
  similar structural applications.
  __ is heated to about
  700 degrees Celsius by conduction, convection and radiation

Answer 6

tempered or toughened glass

Question 7

• is semi tempered or semi
  toughened glass. The heat
  strengthening process involves
  heating annealed glass back up to
  about 650 to 700 degrees Celsius
  and then cooling it quickly,
  although not as fast as with
  toughened glass.
  -not often used in balustrades or similar
  structural applications because of its limited strength.

Answer 7

heat strengthened glass

Question 8

-is a basic product formed from
the annealing stage of the float
process. The molten glass is allowed
to cool slowly in a controlled way
until it reaches room temperature,
relieving any internal stresses in the
glass.
-is used as a
base product to form more advanced glass types.

Answer 8

annealed glass

Question 9

different types of glass

Answer 9

insulated glazing
stained glass
glass blocks or glass bricks
glass wool
architectural glass
chemically strengthened glass

Question 10

__ consists of two or more glass
window panes separated by a space to reduce
heat transfer across a part of the building
envelope.

Answer 10

insulated glazing

Question 11

Used for making decorative windows and other
objects through which light passes. Strictly
speaking, all colored glass is “stained,” or
colored by the addition of various metallic oxides while it is in a molten state.

Answer 11

stained glass

Question 12

are manufactured from two different halves and they are pressed and annealed together while in the
melting process. These are used for architectural
purposes in the construction of walls, skylights etc

Answer 12

glass blocks or glass bricks

Question 13

Is an insulating material made from glass fiber arranged using a binder into a texture similar to wool. It is used as hollow walls and drywall insulation. Additionally, it is also used for roof insulation in auditoriums and
suspended ceilings

Answer 13

glass wool

Question 14

Is used as a building material. It is most typically
used as transparent glazing material in the building
envelope, including windows in the external walls.

Answer 14

architectural glass

Question 15

Is a type of glass that has increased strength as a result of a post-production chemical process. When broken, it still shatters in long pointed splinters similar to float glass. For this reason, it is not considered a safety glass and must be laminated.

Answer 15

chemically strengthened glass
