Description
Low
emissivity glass (Low e glass) is a kind of specialty glass with
excellent functional performance characteristics of solar control.
Low e glass is generally coated with multi-layers of metal oxides
and some other materials, designed to allow transmission of high
level of visible light, reflect UV and infrared radiations. In
order to satisfy customers' diverging demands for Low e glass
installation under different climatic conditions, a full range of
Low e glass products are produced: covering High Transmittance Low
e glass;High Shading Low e Glass; Double Silver Low e glass;
Temperable Low e glass.
High
Transparence Low e Glass
Functional Performance
Characteristics:
1.
High level of visible light transmission: excellent natural
lighting with neutral color effect.
2.
High level of solar energy transmission: good solar energy
transmission, with shading coefficient (SC) greater than
0.5.
3.
High reflectance of infrared radiation: effective control of heat
loss from building, with a thermal conductivity value (U
Value).
High
Shading Low e Glass
Functional Performance
Characteristics:
1.
Desirable level of visible light transmission: reduce solar heat
gain through higher reflection.
2.
Lower solar energy transmission: effectively reduce solar heat
radiation into interior of building, providing good solar heat
insulation with a Shading Coefficient (SC) less than
0.5,
3.
High reflection of infrared: with a relatively low heat gain or
heat loss value (U Value); effectively reduce secondary infrared
radiation from passing through glass into interior of
building.
Double Silver Low e Glass
Functional Performance
Characteristics:
Double
silver Low e coated glass is a more complex high performance
specialty coated glass, incorporated two layers of silver oxide
coatings. The double silver coated glass has the following
functional performance characteristics:
1.
High level of visible light transmission: provide a natural
lighting, with a neutral exterior appearance.
2.
Very low shading coefficient: effective in reducing solar heat
radiation from reaching the building interior, especially for
infrared heat radiation.
3.
Very low heat gain or heat loss value (U Value): good heat
Insulated, effectively reduce heat gain in summer and heat loss in
winter.
Temperable offline Low e Glass
The
soft-coated metallic layers are relatively unstable; hence it
usually needs to be used in the insulated Glass unit within a short
period. We have been able to improve the adhesions between
different coated layers and the stability of the layer structure so
that the soft-coated Low e glass/off line low e glass can be
subjected to tempering or further processing.
Applications:
High
Transparence Low e Glass Applications:
1.
High Transparence Low e Glass is most suitable for the
installations in the regions with cold weather. Such installation
can allow most of solar energy transmitting in while reflecting the
infrared radiation back to indoors from domestic appliances and
human bodies, thereby reducing its indoor energy consuming
effectively.
2.
The high transparence low e glazing of installations requires a
high level of sunlight, with neutral aesthetic
appearance.
High
Shading Low e Glass Applications:
1. High
shading low e glass is suitable for the installations in southern
region as well as in northern region. High shading low e glass can
effectively reduce much more solar heat transmission through glass
into interior in summer than that in winter. On balance, high
shading low e glass can provide an effective overall solar heat
control function since the solar energy intensity in winter is only
1/3 of that in summer.
2. With
reduced light transmission through the glass, high shading low e
glass also provides good reflective and decorative
effect.
Double Silver Low e Glass
Application:
Double Silver Low e Glass is
suitable for general application under
various geographical locations and climatic
conditions.
High
transparent Low e glass provides high visible light transmittance,
high solar power transmittance and extremely high XIR reflectance.
Its light exterior colors are applied to buildings with a
transparent exterior design and natural lighting in colder
regions.
Sun shading Low e glass provides moderate visible light
transmittance, low solar power transmittance and extremely high XIR
reflectance. Sun shading Low e glass is applied to areas which is
hot in the summer and warm in the winter. Sun shading Low e glass
is produced in a variety of exterior colors which provides the
designer with many options.

Advantage:
We can also manufacture products of
special specifications and colors according to customers
‘requests.
1、The overall
process of Low e glass combines equipment from world leading
suppliers: VON ARDENNE for coating and control; BENTELER for
cleaning and drying; HEGLA for complete glass panels handling. The
optimum integration of these processes ensures an efficient and
stable production of temperable off-line LOW E coated glass on a
large scale.
2、The main
coating system of Low e glass incorporates unique gas separation
and cathode deposition techniques. This enables the production of
high quality temperable LOW E coated glass while offering a range
of options for colors and transmittance according to customer’s
requests.
3、The unique
design for coating deposition combined with the hard-wearing
antioxidant protective layer gives off-line LOW E coated glass
outstanding performance in severe downstream treatment processes
such as cutting, edging, tempering and insulating. Furthermore,
when a glass panel consists of both flat and curved surfaces, the
color on both surfaces will match.
