Glass Options

UNDERSTANDING GLASS

Glass is a translucent or transparent material which is made by pouring molten glass over a layer of tin. Molten glass is made up of limestone, iron oxide for color, dolomite, slat cake and sand exposed to a temperature of 1500o Celsius for a considerable time

Following are the various types of glasses available with us:-

TYPES

Float or Annealed Glass

Annealed glass are glass sheets having great optical clarity and can be easily drilled, polished or machined. This type of glass is produced by heating molten glass and then left for cooling at room temperature.

Toughened Glass

This type of glass is four times stronger than an annealed glass. It is a highly safe glass as when broken it shatters in small cubes of glasses that are harmless. This type of glass is produced using an annealed glass which is heated to over 500o Celsius and then suddenly exposed to cooling. Sudden cooling gives it extra strength and makes it impact resistant. Cutting, drilling and machining is difficult in this glass

Heat Strengthened Glass

This type of glass is stronger than annealed glass as it is subjected to controlled heating followed by controlled cooling. It is highly thermal resistant and does not shatter in small pieces when broken. It breaks in larger pieces of glass that stay together making it harmless for the public nearby. Cutting, drilling and machining is difficult in this glass

Frosted Glass

It is also called as a privacy glass. It allows very less light to pass through as it is made up from acid etching method.

Insulated Or Double Glass

When 2 or more glasses are sealed together, with air in between, it forms an insulated glass. This type of glass has the best thermal performance.

Laminated Glass

This glass is a relatively safer glass when compared to above mentioned glasses. It is made by permanently bonding 2 or more glasses with one or more layer of PVB. On impact when the glass gets broken it does not shatter. It keeps on sticking to the polyvinylbutryal layer.

Tinted (Colored) Glass

Tinted glass is also called as a colored glass. It is used for anti-glaring purpose to offer a soothing experience to eyes. This type of glass should be carefully selected as the light transmission through it is lesser than the other types of glass.

Reflective Glass

This type of glass has the property of significantly cutting down the light as well as heat as it is covered with advanced coating. It allows natural light to come in however blocks the heat and radiation. This type of glass is used to cover huge buildings or offices.

Borosilicate Glass

It also called as Pyrex glass and used as a heat resistant glass. It is not affected by heat as it has low heat coefficient of expansion. However a sudden change in temperature can cause it to break but not shatter which also makes it a safe glass.

GLASS MYTH BUSTER

Over the past decade, lot of modifications have taken place in the methods of producing a glass. As a result the glass types have also evolved. In such a case it becomes difficult for a layman to decide as to which glass would best suit his/her purpose. Along with it also comes in lot myths that are discussed below.

 

MYTH BUSTER 1:

People think that more the glazing of the glass better would be the sound insulation

This is not true as more the thickness of the glass better is the sound dilution. Therefore as an example, a 12mm gazing gives a better sound insulation than a 7mm gap plus 12 mm glazing.


MYTH BUSTER 2:

While installing glass there is no need of validating wind flow

This is again not true. Glass should never be installed without wind validation. It is just not a material. Your glass provider would be the best judge to guide you.


MYTH BUSTER 3:

Sound gets reduced by 40 decibels with fenestra windows

This may not always be true as how much of sound gets reduced actually depends on the level of noise outside the window.


MYTH BUSTER 4:

Thick glass reduces sound

The sound insulation property works in a different way in glass. More the thickness of the glass better is the sound insulation.
