| This Light Reflectance Selector identifies USG ceiling panels that efficiently reflect light within a space to enhance indirect lighting, reduce energy consumption and create a warm, luminous aesthetic. Measured per ASTM E1477, LR value represents the percentage of light reflected from the surface of a material. The industry average for panels is LR .70 to .80, and values above LR .85 are considered high. USG offers numerous panels with LR values at these levels, including MARS CLIMAPLUS, RADAR ILLUSIONand RADAR CLIMAPLUS ILLUSION with LR .89. |
