Glass is a vital part in insulating the windows and making these windows Energy Savers.The following are taken into consideration while choosing the right glass: Security, Energy Saving, Sound Reduction, Light requirement.
Float glass gets its name from the modern process used to create large, thin, flat panels from molten glass.
Annealed glass is a piece of float glass that has been cooled in a slow and controlled manner. This slow cooling process reduces the internal stress within the sheet of glass so that it becomes stronger.
These are standard float glass but pigmented in various colours in order to typically absorb solar radiation. Tinted glass takes care to a smaller extent of thermal insulation and to larger extent of solar radiation.
These are float glass with metallic coating thus helping to reflect back the solar radiation thus taking care of thermal insulation better than tinted glass and also solar radiation.
These are float glass which have been tempered under very high temperature, thus making them much stronger than the normal float glass. Due to heating they become brittle and because of that when broken they shatter into small pieces like automotive glass.
When two glass sheets of any of the above mentioned glasses are sandwiched together with one or more layers of PVB plastic or resin it is called laminated glass. The process of sandwiching/lamination makes the glass much stronger and prevents easy breakage. Due to the PVB Plastic or resin in between, the glass does not shatter when it breaks.
