solar reflective index of timber deck

Stylish, low maintenance, stain resistant, wear ... - Reading Rockwear resistant alternative to concrete pavers. Single slab porcelain pavers offer an exceptional paving solution where high stain resistance, scratch resistance, fade resistance, frost resistance and low maintenance are important. At just 3/4" thick, they are much lighter and easier to transport and install than concrete p

Solar Reflectivity (R) & Solar Reflectance Index (SRI) by Color ...solar Reflectance index (SRI) by Color. solar reflectivity or reflectance is the ability of a material to reflect solar energy from its surface back into the atmosphere. The SR value is a number from 0 to 1.0. A value of 0 indicates that the material absorbs all solar energy and a value of 1.0 indicates total reflectance. Energy Star requires an initial SR value of 0.25 or higher for steep slope (>2:12) roofs and 0.15 or greater after three years. Low slope roofs require an initial SR value of 0.65 or ...
