Glass panels for building

The glass technologies have abounded by heaps and bounds and so has the types of glass has increased to a wide range of types.

Types of glass

1.) Sheet glass
Sheet Glass were glasses that were manufactured traditionally by cutting the sheets of glass from large blocks of glass, which cutting produced less quality of glass in comparison to float glass.
2.)Float glass
The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, which pioneered the technique (invented by Sir Alastair Pilkington) in the 1950s
3.) Clear glass
The glass that is used conventionally and most commonly used for windows etc, it is colorless and plain which has no special features.
4.) Stain glass
The stained glass is traditionally used in churches, also called the lead glazing, It is the glass window which portrayed the gospel stories to convey the message during the times where the gospel was not available to the masses, during the pre-printing era.
5.) Beveled edge glass
A glass that has the glass edge has been beveled to give a special decorative feature by reflecting light at the edges.
6.) Tinted glass
The glass which is colored to give an aesthetic feature but may have some thermal properties.

7.) Tempered glass
The glass that has been strengthening to resist impact, generally used for glass curtain walls.
8.) Laminate glass
The laminate glass is constructed by laminating thin sheets of glass to create the laminate glass. The glass does not shatter when broken but remains intact without shattering to the floor. The strength of laminate glass is not as strong as the tempered glass.
9.) Skylight glass
A composite of Tempered and laminated glass, constructed in such a way and strong enough for a maintenance worker to walk on the top of the skylight for cleaning purposes etc.
10.) Energy Efficient glass- Low E Glass
Glass which is made to resist the infrared ray and allow the light component inside the building for comfort. As this also saves the cooling bill during summer and thereby called EE glass, as it saves energy. There many types of glasses with differing solar coefficients, the type of glass selected will depend on the heat load one is trying to achieve and the budget for construction. These glasses are generally very expensive.

11.) Chromogenic glass * Net Zero Energy Design by Tom Hootman
a) Electrochromic glass, responds to the voltage electrical charges
b) Gas-chromic glass, responds to the flow of hydrogen levels
c) Photochromic glass, glass that responds to exterior light levels
d) Thermochromic glass, glass that responds to exterior temperature changes

12.) Colored glass
Are glasses that are back painted glass which has a decorative effect as the painted back appears with a glass effect and are generally used for the interiors of the buildings.

Other Terminologies for glass

Soft Coat -a coating which helps to reduce the heat into the building

Effect of soft coat on glass [amels

soft coat glass

Hard Coat-a coating which helps to reduce the heat into the building but not as efficient as the soft coats.
Heat soaked glass or Heat strengthen glass

Glass when is manufactured has impurities which will expand when is subjected to the heat from the sun. and this relative and differential expansion cause the glass break and shatter, heat soaked or heat strengthens glass is a process where the Glass is placed in a high-temperature heat furnace so that the defective glasses are eliminated during the heating in the furnace, so that after installation glasses do not fall off,
