Glass it the right Construction

Glass is a hard substance which may be transparent or translucent and brittle in nature. It is manufactured by the fusion process. In this process sand is fused with lime, soda and some other admixtures and then cooled rapidly. Glass is used in construction purpose and architectural purposes in engineering.

Engineering Properties of Glass

  1. Transparency
  2. Strength
  3. Workability
  4. Transmittance
  5. U value
  6. Recycle properly

Transparency is the main property of glass which allows the vision of the outside world through it. The transparency of glass can be from both sides or from one side only. In one side transparency, glass behaves like a mirror from the other side. Whereas Strength of glass depends on the modulus of the rupture value of glass. In general, glass is a brittle material but by adding admixtures and laminates we can make it as more strong. Glass can be molded into any shape or it can be blown during melting. So, the workability of glass is a superior property of glass. In case of the visible fraction of light that passing through the glass is the property of visible transmittance. Also for glass U value represents the amount of heat transferred through the glass. If a glass is said to be insulated unit then it should have lower u value. Any glass can be 100% recyclable. It can also be used as a raw material in the construction industry.

The types of glass used in construction:

  • Float glass –  Float glass is made of sodium silicate and calcium silicate so, it is also called as soda-lime glass. It is clear and flat so, it causes glare.  These are used as shop fronts, public places, etc.
  • Shatterproof glass – Shatterproof glass is used for windows, skylights, floors, etc. Some type of plastic polyvinyl butyral is added in its making process. So, it cannot form sharp-edged pieces when it breaks.
  • Laminated glass – Laminated glass is the combination of layers of normal glass. So, it has more weight than a normal glass. It has more thickness and is UV proof and soundproof. These are used for aquariums, bridges, etc.

  • Extra clean glass – Extra clean glass has two special properties, photocatalytic and hydrophilic. Because of these properties, it acts as stain proof and gives a beautiful appearance. Maintenance is also easy.
  • Chromatic glass – Chromatic glass is used in ICU’s, meeting rooms, etc. it can control the transparent efficiency of glass and protects the interior from daylight. The chromatic glass may be photochromic which has light-sensitive lamination, thermos-chromatic which has heat-sensitive lamination and electrochromic which has electric lamination over it. 
  • Insulated Glazed Units – Insulated glazed glass units contain glass is separated into two or three layers by air or vacuum. They cannot allow heat through it because of air between the layers and acts as good insulators. These are also called as double glazed units.
  • Tinted Glass:  Tinted glass is nothing but colored glass. A color producing ingredients is mixed to the normal glass mix to produce colored glass which does not affect other properties of glass.
