Low-e Glass
refers to low emissivity glass. It is a type of insulating glass with special transparent
metal coating on one side known as Low-e coating. This coating helps to control
the rate at which heat enters or goes out of the premises. It can also be made
to restrict some of the solar radiation transmitted through glass. Initially
low-e glass was majorly used in commercial applications, but now they are being
highly used for residential purposes also. It is suitable for all types of
climate conditions with variations in the laminated according to the need.
Low-e glass can
be hard coat or soft coat. Low-e glass is an effective way of energy saving. It
helps to keep the long wave radiation inside. During winters, the Low-E coating
prevents the heat emitted at night from radiators, wood stoves, etc. and helps
to reflect radiant room-side heat back into the building. While during summer,
it reduces the amount of heat transferred through the window by filtering the
sun’s short wave radiation. They also comply with the Building Codes’
provisions for energy efficiency.
Low-e glass coatings
provide multiple performance levels. It can successfully be used in various ways
including laminated glass, single glazing or double glazed windows. It highly
reduces the damage that can be caused to the furniture and interior by ultra
violet rays by reducing the amount of heat conducted through the glass. It can
also be used in a combination of laminated and toned glass for improved
performance on doors and windows.
Double glazingunits are extensively used in doors and windows for residential and commercial
building and architectural applications. They are also known as insulating
glass units. Double glazing units incur higher initial cost than single glazed
windows. They are designed to provide superior performance and conform and have
good capability to modify the environment. Double glazing units retain views
and natural lights and at the same time provide better energy and thermal
performance as compared to single glazing units.
Double glazed
units save highly on energy bills and reduce outside noise drastically. A variety
of styles and colours are available in these units and they can also be custom made to suit customer’s requirements. They are
suitable for residential as well as commercial applications including hotels
and offices. They provide enhanced security and at the same time help in
beautification of a home or building. They provide far better security and
strength as compared to single gazing units. They also provide virtual
elimination of condensations. They also provide clear vision even at low
temperatures. They are needed to comply with the Australian Standards.
In a double
glazed unit, two panels of glass are parted by an air space which acts as an
insulator against heat gain or heat loss. They keep the premises warm in summer
and cool in summer. One important benefit is that they need no maintenance with
no fading, painting or warping. Manufacturers provide high quality insulated
glass at highly reasonable prices complying with the standards. These units can
be combined with low-e glass to achieve better results and heat reduction.
During extreme weather conditions such as cyclones, both double-glazed window
panels can be toughened in order to make the windows much stronger and
proficient of surviving with the most life-threatening weather events.
