ABSTRACT:
An insulated glazing unit is described and includes a first transparent substrate spaced apart from a parallel second transparent substrate, a sealed void space defined between the first transparent substrate, second transparent substrate, and the window mounting member, and an infrared radiation reflecting multilayer polymeric film disposed between the first transparent substrate and the second transparent substrate. The infrared radiation reflecting multilayer polymeric film includes a plurality of alternating polymeric layers of a first polymer material and a second polymer material. At least one of the alternating polymer layers is birefringent and oriented. The alternating, polymeric layers cooperate to reflect infrared radiation.
