The general
double glazing units are constructed from glass with the minimum thickness of 3
mm to the maximum thickness up to 16 mm. The encapsulated space of the double glazing units will essentially be filled with argon gas to enhance the
insulating properties of the double glazing unit. The argon gas, filled in the
double glazing unit, is used for the wider cavities. Argon is not suitable for
the smaller cavities, so in addition xenon and krypton gases are used to obtain
the desired result. Double glazing units are fitted to reduce the energy loss
and condensation for building. The cost of the double glazing unit varies with
the type of the material used to form a spacer. The spacer used in the double
glazing unit can be of the following type:
• Regular metal spacer
• Sealant type spacer
• Non-metal synthetic spacer
• Hybrid
The E in
low E glass stands for “emissivity”. Low E glass reflects the radiation rather
than absorbing it as a result increasing its performance. Emissivity is the
measure that detects how much heat energy is emitted by a material. A very slim
coating of either tin oxide or silver is deposited onto the surface of the low
E glass to reduce the amount of heat it emits. Low E glass allows the natural
light but blocks the solar radiation. This protects your home from the
undesired heat. However, in winter, low E glass is proved as a benefit, as It
helps keep warmth in your home. So, next time you purchase new windowpanes for
your home, make sure that it is coated with the good quality low E glass. If
you are thinking of replacing the older windows of your home that do not have E
glass, then no need to replace the whole window. You can just get the older
window coated with the insulated glass to save cost. This procoss is very economical.
Low emissivity is very acute component of the great performance energy
effective windows.
Double
glazing units can sometimes weaken, smash or crack due to accidents, the need
for upgrading, weather conditions or unavoidable fault. Overnight condensation
moisture collecting over the window pane frequently can eventually weaken the
pane, due to the wet. Some of the reasons why panes may weaken are listed
below:
• There can be a fitting fault.
• More often, the failed part is the one,
which faces the Sun.
• Rain seems to be an obvious factor in
collecting the moisture.
• The rarest reason is the poor quality
seal, which is fitted in the windowpane.
The double
glazing unit is manufactured by the various materials but some of the common
materials are listed below along with the advantages:
PVC: Its advantages are:
• Tested and proved accurate even in the
worst weather
• Virtually maintenance free
• Wide diversity of locks available
Metal: Advantages are:
• No corrosion
• Strongest
• Will never twist
Wood: Its advantages:
• Enduring and durable
• Most environmental friendly
• Offers maximum security
Metallic
low E coating can be categorized as two: Hard coat and soft coat. Among the
two, soft coat has the better insulating characteristics.
