Patent ID: 7709095

Claim:
A layered structure comprising consecutively: an infra-red reflecting layered structure, said infra-red reflecting layered structure comprising: a first transparent substrate layer; a first metal oxide layer; a first silver containing layer; a second metal oxide layer; a second silver containing layer; a third metal oxide layer; a first adhesive layer; a second transparent substrate layer; a second adhesive layer; and a glass substrate, wherein said infra-red reflecting layered structure further comprises at least one protective intermediate layer comprising gold, said protective intermediate layer being located on both sides of at least one of the first and second silver containing layers; said first, second and third metal oxide layer having a refractive index of at least 2.40 at a wavelength of 500 nm and said infra-red reflecting layered structure, having a visual light transmittance (VLT) higher than 70% and a solar heat gain coefficient (SHGC) lower than 0.44.
