2. GLASS
• Glass is an amorphous (non-
crystalline) solid which is often transparent
and has widespread practical,
technological, and decorative usage in
things like window panes.
2

3. ARCHITECTURAL GLASS
• Used as a Building Material.
• Used as transparent glazing material in
the building envelope, including windows
in the external walls.
• Also used for internal partitions and as an
architectural feature.
• Glass is often of a safety type, which
include reinforced, toughened and
laminated glasses.

4. TYPES
• Flat glass
• Safety glass
• Acoustic glass
• Coloured glass
• Special glass
• Extra clear glass
• Acid etched glass
• Etched glass
• Fire rated glass
4

5. • Mirror glass
• Coated glass
• Pattern glass
• Annealed glass
5

6. FLAT GLASS
• There are 2 types of flat glass
1.The float
2. The printed glass
6

7. FLOAT GLASS
• Float glass is a transparent, colorless or
colored glass, with uniform thickness and
homogeneous mass.
• It is the ideal glass for application that
demand perfect visibility.
• Has high light transmission,double
glazing.
• It is used in automotive industry, of
household appliances, civil construction,
furniture and decoration. 7

9. PRINTED GLASS
• The printed glass is a translucent flat
glass, colourless or coloured, which
receives the printing of a pattern (drawing)
when is leaving the furnace.
• It is used in civil construction, household
appliances, furniture and decoration.

11. SAFETY GLASS
• Produced from the float glass, aiming to
reduce the risks in case of accident and
accidental break.
• The safety glasses are defined by ABNT
as “those that, when broken, produce
fragments less susceptible to cause
serious injuries”.
11

12. SAFETY GLASS TYPES
1. Tempered glass
2. Laminated glass
12

13. TEMPERED GLASS
• The tempered glass is a float glass that
receives a thermal treatment (it is heated
and cooled quickly), which makes it more
rigid and resistant to breakage.
• If it breaks it produces tips and edges less
cutting, and it fragments in small round
pieces.
13

14. 14

15. LAMINATED GLASS
• The laminated glass is composed by two glass
plates intercalated by a plastic skin of great
resistance.
• The laminated glass is used as cover, facades,
balconies, guardrail, doors, windows, partitions,
showcase, floorings and others.
• The laminated glass has other benefits, as the
reduction of external noise entrance (when
compared to the common glasses) and the
protection against UV (Ultraviolet) rays.
15

16. 16

17. 17

18. ACOUSTIC GLASS
• the acoustic glasses that impede the noise
from passing from one environment to the
other.
• This sound comfort can be obtained
through two solutions: acoustic laminated
glass and the double glass (or insulated).
18

19. 19

20. ACOUSTIC GLASS TYPES
1. Acoustic laminated glass
2. Double glass or insulated
20

21. ACOUSTIC LAMINATED GLASS
• It is a glass laminated with a special PVB
(acoustic)
• Because of this it works as an excellent
acoustic insulator.
• It is an innovative product that ensures a
powerful protection against noises.
21

22. 22

23. INSULATED GLASS
• It is the set of two glasses separated by an
air or gas layer, conferring a reduction in
the sound propagation, in the entrance of
heat and endless decorative combinations.
• the double glass is present in our daily life,
as for instance, in freezers and refrigerators
doors (with the thermal insulation function).
• The double glazing can be composed by
any type of glass, improving the thermal
and acoustic performance.
23

24. • The double glazing can be composed by
any type of glass, improving the thermal
and acoustic performance.
• Besides that, it can be equipped with
internal blinds that give the set a
differentiated aesthetic effect.
24

25. 25

26. COLOURED GLASS
• There are two types of colored glasses:
1.painted
2. screen-printed.
26

27. 27

28. PAINTED GLASS
• Produced from a float glass, it receives in
the production line a special painting,
which gives to it, besides the coloured and
shiny finishing, greater resistance.
• Its versatility makes it possible to use in
furniture, residences, offices, hotels,
stores and museums.
28

29. 29

30. SCREEN PRINTED GLASS
• Screen-printed glasses are glasses one
side of which is covered with permanent
decorative designs.
30

31. 31

32. SPECIAL GLASS
• With the technological advance in the
creation of micro layers, several special
types of glasses have come up.
• Actually, theses glasses have layers of
diverse type of materials, these layers of
microscopic dimension that offer several
differentiated characteristics to the glass.
32

33. SPECIAL GLASS TYPES
• Sun protection glass
• Self-cleaning glass
• Low reflection glass
• Low-emissivity glass
33

34. SUN PROTECTION GLASS
• Also known as reflective glass or solar
control
• Being indicated for places where there is
great incidence of solar rays, like facade of
buildings, windows, doors, balconies and
cover, as it provides a better thermal
comfort.
• Function to reduce the entrance of heat
inside the environment, besides producing a
control in the entrance of light for the interior
of the buildings 34

35. 35

36. SELF CLEANING GLASS
• The self-cleaning glass is visual identical to
the normal glasses.
• It ensures a clear vision in all the situations,
even on rainy days; and the self-cleaning
layer is integrated to the glass and because
of this has a high level of durability, and do
not wear out over the time.
• It shall be applied always in the external
part of the buildings like facades, covers,
windows, doors, balconies and other in
highly polluted areas. 36

37. 37

38. LOW REFLECTION GLASS
• It is an extra clear float glass
• Ideal for showcases, showrooms,
museums, authorized dealers, displays
and other types of applications that need
to avoid the discomfort of the light
reflection in the glass, which many times
forces the person to create a shadow in
front to observe the object that is behind
the glass.
38

39. 39

40. LOW EMISSIVITY GLASS
• It does not enables the heat exchange
between the internal and external
environment.
• It has the appearance of a colourless float
glass, reducing the entrance of heat or
cold.
• Used in the commercial refrigerating
market and on civil construction, in
facades and covers.
40

41. 41

42. EXTRA CLEAR GLASS
• It is an extremely transparent glass, that
is, without the green shade common to the
colourless glasses.
• This happens because in its composition
there is one less concentration of iron
oxide.
• Used in civil construction, decoration and
household appliances.
42

43. 43

44. ACID ETCHED GLASS
• They are glasses treated with acid and
with whitish appearance.
• It offers several aesthetic options for
architect and decorators.
44

45. 45

46. ETCHED GLASS
• It is a glass worked with jets of sand
grains that mechanically attack the glass,
transforming it in translucent and slightly
rough. It is used in furniture and
decoration.
46

47. 47

48. FIRE RATED GLASS
• The fire-rated glasses, without the metal
mesh, are laminated glasses composed
by several intercalated plates with
transparent chemical material that melts
and dilates in case of fire.
48

49. 49

50. ANNEALED GLASS
• It is common glass that tends to break into
large, jagged shards.
• It is used in some end products and often
in double-glazed windows.
• It is also the starting material used to
produce more advanced products through
further processing such as laminating,
toughening, coating, etc.
50

51. 51

52. MIRROR GLASS
• Mirrored glass is gaining a more
prominent place in architecture, for
important functional reasons as well as for
the aesthetic effect.
52

53. 53

54. PATTERN GLASS
• Patterned glass is flat glass whose
surfaces display a regular pattern.
• Patterned glass is mostly used in internal
decoration and internal architecture.
54

55. 55

56. COATED GLASS
• Surface coatings can be applied to glass
to modify its appearance and give it many
of the advanced characteristics and
functions available in today's flat glass
products, such as low maintenance,
special reflection/transmission/absorption
properties, scratch resistance, corrosion
resistance, etc.
