The ideal solar collecting energy glazing material is transparent to short-wave infrared radiation and opaque to long-wave radiation.
Optical properties of some typical glazing materials:
|Short-wave Infrared Solar Transmittance||Long-Wave Infrared Transmittance|
|Window glass (float glass)||4||0.83||0.02|
|Acrylic Glass - Poly(methyl methacrylate) (common trade names Plexiglas, Limacryl, R-Cast, Perspex, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass and Lucite)||3||0.82||0.02|
|Polyvinyl Fluoride (known by his trade name Tedlar from DuPont)||0.1||0.92||0.22|
