Main types of Glass:
1.
2.
3.
4.
Annealed Glass.
Toughened Glass.
Laminated Glass.
Coated Glass.
5. Mirrored Glass.
6. Patterned Glass .
7. Extra Clear Glass
(Crystal Glass).
1. Annealed Glass: is the basic glass. It breaks
into large pieces, it is the starting materials to
produce more advanced glass products.
2. Toughened Glass: it is made from annealed
glass, but treated with a tempering process to
be more resistant to breakage.
3. Laminated Glass: is made of different layer
of glass with an Interlayer of Polymetric
material bonded in between.
4. Coated Glass: Surface coatings is applied to glass to
modify its appearance and give it many advanced
characteristics and functions, such as low
maintenance, special
reflection/transmission/absorption properties, scratch
resistance…
5. Mirrored Glass: it is normal glass with a fully
reflective metal coating, generally made of silver,
aluminum, gold or chrome, and the sealed with a
protective layer.
6. Patterned Glass: Patterned glass is flat glass whose
surfaces display a regular pattern. The most common
method for producing patterned glass is to pass heated
glass between rollers whose surfaces contain the negative
relief of the desired pattern
7. Extra Clear Glass (Crystal Glass): it is not the result of
annealed glass, but instead a specific type of melted glass.
Extra clear glass differs from other types of glass by its
basic raw material composition. This glass is made with a
very low iron content in order to minimize its sun
reflection properties. It is mostly used for solar energy
applications where it is important that the glass cover lets
light through. Anti-reflective properties can be further
increased by applying a special coating on the low-iron
glass. It can also be used in windows or facades for
excellent clarity to appreciate true colors and to enjoy
unimpaired views.
Other types of Glass:
1. Fused Glass.
2. Wired Glass.
3. Stained Glass.
4. Tinted Glass.
5. Murano Glass.
1. Fused Glass: Glass fusing is the joining together of
pieces of glass at high temperature, usually in a
kiln.
2. Wired Glass: Wired glass is a type of glass into
which a wire mesh is embedded during production.
3. Stained Glass: it is created from colored glass,
mostly used for significant buildings.
4. Tinted Glass: it is normal glass into whose melt colorants
are added for tinting and solar-radiation absorption
properties.
5. Murano Glass: Murano’s glassmakers led Europe for
centuries, developing or refining many technologies
including crystalline glass, enameled glass (smalto),
golden glass (goldstone), multicolored glass (millefiori),
milk glass (lattimo), and imitation gemstones made of
glass.
New types of Glass:
1. Thermochromic glass Windows.
2. Smart glass, or switchable glass.
1. Thermochromic glass Windows.
Thermochromic Smart Glass, Changes its transmittance when struck by incident
solar radiation. It becomes Darker as the Temperature increases.
Benefits of Thermochromic Smart Glass:
• Can be installed just as normal glass into a building facade
• Internal PVB lamination gives improved safety and noise insulation
• Glass changes between tinted and clear states within minutes of being triggered
• Maintains a view to the outside at all times
• Reduces glare and hence the resulting discomfort and loss of productivity
• There are no wires, since it is not electrically-powered
• Reduces air-conditioning usage, thanks to rejection of infrared
2. Smart glass, or switchable glass.
A smart glass or switchable glass is a glass whose
light transmission properties are altered when voltage,
light, or heat is applied. In general, the glass changes
from transparent to translucent and vice versa,
changing from letting light pass through to blocking
some wavelengths of light and vice versa.
