2.4
ROLLER SHADE TYPE AND SHADECLOTH
 
** NOTE TO SPECIFIER ** Delete choices below not included in selections made in paragraphs above. Yarns are opaque. Visible light transmission through the interstices of the fabric shall be in the 2-5 percent VL transmission range, which varies with color and is used as the guide for fabric selection. Non-opaque yarns in the 3 - 5 percent openness factor range generally have a 20 - 30 percent visible light transmission; this provides very high surface brightness shade bands. In that event the visible light transmission of the glazing plus the VLT of fabric shall be evaluated. Openness factor, the traditional means for matching shadecloth to glazing, is not appropriate for fabrics with non-opaque yarns and high visible light transmission regardless of openness factor. Visible light transmission, and ultimate surface brightness are the most accurate determinant of fabric selection.
