Double Glazed Glass offers best solutions for sound insulation, thermal insulation & safety.
Note: The ticks are not mathematical in nature, just an indication of effectiveness.
Four ticks do not necessarily mean twice as effective as two ticks.

Advantages |
Limitations |
| Float Glass |
| Derives its name from the name of its manufacturing process, the float process. In this process, a sheet of glass is passed repeatedly on a bed of molten tin. This process gives uniform thickness and a bright surface to the glass |
Gives high visibility and clarity Can be further fabricated into other forms of glass like reflective, tinted, toughened etc. |
Does not offer enhancedfeatures like insulation protection etc
Vulnerable to break ins. |
| Double Glass Unit |
| The insulated Glass unit is a set of 2 layers of glass
with an aluminium spacer in between. Sealed to form
a single unit with an air gap between the two glasses.
Space between glasses is filled with dry air, which
improves insulation. |
Improved insulation reduces air
conditioning/heating bills
Improves sound insulation
significantly, reducing road and
aircraft noise
Slender frames fit perfectly well
with the look of the windows.
Increases security |
In case of breakage,
entire Double glazed unit
has to be replaced.
In rare cases, a fault may
develop in the unit,
leading to condensation. |
| Reflective Glass |
| The metallic coating on top of the float glass reduces
the impact of radiation. The special metallic coating also
produces a mirror effect preventing a person from
seeing through the glass. |
Reduces the impact of light and
heat radiation from the sun.
Enhances the effectiveness of air
conditioners. Ideal for rooms
exposed to the sun.
View from outside is blocked during
the day. The view from inside is clear |
After dark, view from
outside becomes clear.
Windows may require
blinds at night. |
| Toughened Glass |
| Produced by applying a special treatment to ordinary
float glass. The treatment involves heating the glass to
very high temperatures (about 620 degrees C) so that
it begins to soften; and then cooling it rapidly. |
Upto 4-5 times stronger than normal
float glass.
Provides enhanced security to
windows. |
The glass cannot be re
worked once thoughened.
Glass likely to get damaged |
