ABSTRACT METHODS of measurement and results are presented for the transmission of long wavelength (> 2.8 micro-meters) and solar, short wavelength 2.8 micrometers) radiant energy by nine common materials that might be considered for covering greenhouses or solar collectors, and by 81 two-layer combinations of these materials. The solar energy transmission (direct beam and diffuse) was measured at angles of incidence between the direct beam and the materials of 0 to 67 deg.
