Claim 0:
1. A layered structure comprising:
an optically transparent layer comprising ultra-high molecular weight polyethylene; and
an IR reflective layer overlying the optically transparent layer, wherein a thickness of the optically transparent layer ranges from approximately 10 micrometers to approximately 1 mm and a thickness of the IR reflective layer ranges from approximately 0.2 mm to approximately 1 mm, the IR reflective layer comprises an IR reflective PVDF foam, and the layered structure has a short wavelength (0.25<λ<5 μm) infrared reflectance of at least approximately 10%, and a long wavelength (8<λ<14 μm) infrared reflectance of less than approximately 10%.
