saving energy insulated low-e glass Bulletproof Glass thermal
Insulating glass is manufactured glass product formed by
partitioning a space with two or more glass sheets by using a
curtain width by an aluminium sash having the interior filled with
effective molecular sieve as an absorbent and then conducting a
sticking with a high strength seal gum. a double sealing must be
adopted in order to guarantee the performance of insulating glass ,
the first sealing utilizes chlorobutyl , the second sealing is
polysulfide adhesive or silicone structural sealing adhesive and
may be chosen by the installing manner of customer .
The heat insulation performance of insulating glass is relatively
ideal among currently all deep processed glass products and is able
to reduce the value of the heat transfer coefficient U effectively
.such glass can greatly decrease the heat transfer coefficient to a
high degree once being charged with an inert gas such as neon,
argon and helium gas.
Generally , insulating glass can reduce the noisy by about 30
decibel and once being charged with an inert gas ,insulating glass
can further reduce the noisy on the previous basis by about 5
No dewing in low temperatures
Enough drier is filled in the spacer bars ,the insulation glass can
effectively absorb the water vapor the insulating glass s cavity
and that is likely to permeate from exterior so as to ensure an
absolutely drying in the insulating glass cavity thereby avoid the
It is broadly used in different kinds of buildings curtain walls
doors and windows ,indoor partitions and indoor freezers.
Products can be randomly combined by transparent glass , main body
colored glass, tempered glass , coated glass , low-e glass,
sandwich glass, glazed glass etc.
What are double glazed windows glass?
An insulated glass unit (IGU) combines multiple glass panes into a
single window system. Most IGUs are double glazed (two panes of
glass) with three panes (triple glazing) or more becoming more
common due to higher energy costs. The panes of glass in IGUs are
separated by a spacer and a still layer of air or gas. The glass is then fitted into
window frames, which is made wider to accommodate the two panes.
The benefits of double glazing
Double glazed windows are an ideal energy efficient choice with the
added benefit of minimising noise. The sealed air gap between the
two panes acts as an added layer of insulation. This added thermal
resistance reduces the amount of heat escaping in winter and keeps
your home at a more comfortable temperature. Double glazing has the
reverse effect in summer, preventing unwanted heat from coming into
the home. This extra insulation lessens your reliance on artificial
heaters and air conditioners and can ultimately reduce your energy
When you are close to a window, your comfort is also affected by
the temperature of the glass. With double glazing it’s harder for
the unwanted outside temperature to transfer through, leaving the
inside pane close to room temperature. Double glazing also reduces
condensation which can result in the unhealthy formation of mould.
Sealed double glazing is effective at reducing medium to high
frequency noise such as the human voice. A difference in glass
thickness between the inner and outer panes will improve sound
reduction even further.
Double glazed windows are considered a safer option when compared
to standard single pane windows. Two sheets of glass are a lot
harder to break than one and for even greater security you can
specify toughened or laminated glass.
What to look for
Amount of space between panes
The typical space between panes ranges from 6mm to 20mm. A minimum
space of 12mm is recommended for optimum thermal performance.
Alternatively, for good acoustic control and to reduce low
frequency noise such as traffic and aircraft, the optimum air gap
recommended is 150mm or over. Note that such large gaps allow convection to occur between the panes and reduce insulating performance.
