MEASUREMENT OF DIRECTIONAL HEMISPHERICAL REFLECTANCE AND CALCULATION OF THE EMISSIVITY OF RADIANCE^™ LOW-E WALL FINISH

Samples of RADIANCE^™ FLAT and EG-SHEL finishes were sent to independent test laboratories for verification of the directional-hemispherical reflectance and the calculation of the total emissivity of each coating.  The average e-value is listed below followed by actual spectral measurements of directional-hemispherical reflectance and emissivity.

The samples were tested and applied in our laboratories, as well as the Bavarian Center for Applied Energy Research, and the Tennessee Technology Institute Research and Development Services.  Actual results are available from Radiance^™ Technical Services upon written request.
