Inorganic Nanometer Transparent Heat-Insulation Coatings for
Glass

Beijing Guobang Technology Development Center has developed an
inorganic nanometer transparent and heat-insulation coatings
that can be used in glass. The new coatings have selectivity to
solar spectrum. After it forms coating layers on glass surface,
the transmitting rate of visible lights in glass is still as high
as 75% and the screening rate of infrared heat reaches 72%. It
can not only retain the transparency of glass but also
effectively block the infrared heat radiation of sunlight. It
can produce a considerable indoor/outdoor temperature
difference, prevent indoor heat from outward conduction through
glass and therefore achieve energy conservation.
   The product uses nanometer inorganic material and has
excellent resistance to aging, fouling, static electricity,
flare and radiation.
