c) Lamination Process
Process
Firstly, the glasses are cut to size, edge worked, fabricated and/or thermally treated as
required. Cleaned and dried glasses are assembled with PVB interlayer of desired thickness and
put through a de-airing process. At this stage the assembled glasses are in semi finished state
and have a translucent appearance.
Subsequently, the assembled glasses are autoclaved at approx 13 bar pressure and 140°C.
During this process the PVB interlayer softens and forms a very strong chemical bond with the
glass surface. After the autoclave process the laminated glass attains its clear appearance
depending upon the interlayer used.

FLOAT GLASS DIVISION
Around 95% of the flat-glass produced in the world is of float type. The most significant
distinction of float glass from other types of flat-glass is its superior quality and distortion free
nature. Float-glass is extremely clear with light transmission upto 90%.
The float process offers advantages over others, mainly on following features:
� Fuel efficiency- The process consumes less fuel to melt one ton of glass when compared to
other processes.
� Quality- It is free from body defects like waves, stones etc.
