*The fenestration properties tests were conducted in accordance with ASHRAE Standard 74-1988, and ASTM E 424-71:2007, Method A, 6.5.2, Selected Ordinates Method. These solar optical properties are used to calculate the Shading Coefficient (SC). The Shading Coefficient is the value that determines the solar heat gain percentage that passes into the interior through the window and shade system. A 1/8 inch double strength glass, a ¼ inch clear plate, and a ¼ inch heat absorbing (H.A.) plate were used in determining the SC of each fabric. Lighter fabric colors provide more solar reflectance while darker ones promote optimal glare reduction and visibility. Results are real data based on a single sampling. For complete fabric specifications, performance values, and larger samples, please contact DW Industry USA.
Ts = Solar Transmittance Rs = Solar Reflectance As = Solar Absorption Tv = Visual Transmittance
1/8CL = 1/8″ Clear Glass 1/4CL = ¼” Clear Glass 1/4HA = ¼” Heat Absorbing Glass
