LOW-Emissivity Coated Glass
Low-E coated glass is also called Low-E glass, Low-E glass is the
glass surface coated with low radiation material silver and metal
oxide film, so that the glass presents different color. Its main
role is to reduce the U value of the glass, and selectively reduce
the Sc, to improve the energy saving characteristics of glass.
Distinguishing features: high infrared reflectance, can directly
reflect the far infrared radiation; the surface radiation rate of E
is low, the ability to absorb foreign energy, then a little heat
radiation; wide range of shading coefficient Sc, in order to meet
the needs of different regions by controlling the amount of solar
The definition of Low-E insulating glass and the comparison of
energy saving with ordinary glass and ordinary insulating glass:
Low-E insulating glass is the first choice of energy saving
building materials, its energy saving characteristics meet or even
exceed the country's public buildings and residential building
materials used in energy-saving mandatory requirements. The utility
model uses the vacuum magnetron sputtering coating method to coat
the surface of the common building glass with the metal silver and
the auxiliary film layer, and then to synthesize the hollow glass
product with a plurality of other processes.
Compared to ordinary energy-saving glass, Low-E insulating products
can use silver’s high reflection characteristics of thermal
radiation, Ensuring that the indoor natural lighting, at the same
time, keep more heat of the sun gear outdoors in the summer,
prevent more indoor heating loss through the glass to the outside
in the winter, Thus play a significant effect of building energy
Compared with ordinary single-layer glass, energy-saving glass
(Low-E insulating glass) insulation, heat preservation effect is
significant, can save energy 67-70%, compared with ordinary
insulating glass energy saving about 40%.
We want to get lighting the same time to control the invasion of
energy, so you can use the LOW-E product’s ratio of visible light
transmittance and the radiant heat factor to measure the
performance of the product.
The core value of LOW-E glass lies in its all-weather and seasonal
A kind of LOW-E product that can be pretreated and toughened after
Not all of the coating material, all the film kind, under all
conditions can produce a toughened LOW-E, toughened LOW-E is a
special LOW-E glass, has great progress in low radiation
LOW-E can be tempered because it is possible to strengthen the
film, so the product has a wider range of applicability, it can be
made to be bended to solve the building elevation of the arc
program, or even the internal arc program.
LOW-E toughened glass production has the characteristics of high
efficiency and mass production, thus creating a more energy saving
and more environmentally friendly social benefits, to provide more
accurate assurance of supply and demand services.
The difference between single silver LOW-E glass and double silver
Double silver LOW-E glass, named for its double layer silver layer,
belongs to a kind of complex LOW-E glass film system. It highlights
the glass on the shielding effect of the solar heat radiation,
cleverly combined high light transmittance of the glass and the
solar heat radiation and low permeability, so compared with
ordinary LOW-E glass, in the case of the same visible light
transmittance it has lower solar transmittance.
