The invention discloses high-performance double-silver low-
radiation energy-saving glass, which belongs to the field of an eco-friendly energy-saving
building material. The structure of an energy-saving glass
membrane layer comprises, in sequence, a glass substrate, a first base layer which is a
silicon nitride layer, a second seed layer which is a
zinc oxide layer, a third functional layer which is silver layer, a fourth protective layer which is a
nickel cadmium layer, a fifth
dielectric layer which is a
silicon nitride layer, a sixth
dielectric layer which is a
tin zinc oxide layer, a seventh seed layer which is a
zinc oxide layer, an eighth functional layer which is a silver layer, a ninth protective layer which is a
nickel cadmium layer, a tenth
dielectric layer which is an aluminum zinc oxide layer, an eleventh layer which is a
silicon nitride layer, and a twelfth protective layer which is a
graphite layer. Through arrangement of a
coating membrane layer material on the glass substrate and arrangement of a
membrane layer thickness, the energy-saving glass reflects gray and blue colors outdoors, and has visible light
transmittance between 42-60%. The energy-saving glass is excellent in performance, has a
shading coefficient less than 0.3 and selectivity coefficient more than 1.4, and is quite suitable for hot areas that have high environment temperature all the year round and intense average sunshine.
