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

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.

3

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

4

• Mirror glass

• Coated glass

• Pattern glass

• Annealed glass

5

FLAT GLASS

• There are 2 types of flat glass

1.The float

2. The printed glass

6

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

8

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.

9

10

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

SAFETY GLASS TYPES

1. Tempered glass

2. Laminated glass

12

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

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

17

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

ACOUSTIC GLASS TYPES

1. Acoustic laminated glass

2. Double glass or insulated

20

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

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

• 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

COLOURED GLASS

• There are two types of colored glasses:

1.painted

2. screen-printed.

26

27

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

SCREEN PRINTED GLASS• Screen-printed glasses are glasses one

side of which is covered with permanent decorative designs.

30

31

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

SPECIAL GLASS TYPES

• Sun protection glass

• Self-cleaning glass

• Low reflection glass

• Low-emissivity glass

33

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

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

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

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

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

ACID ETCHED GLASS

• They are glasses treated with acid and with whitish appearance.

• It offers several aesthetic options for architect and decorators.

44

45

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

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

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

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

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

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.
