The combined wind break and sun screen is made from twisted strips of film material 2.5 mm wide and with gaps of 1 mm between strips. The strips, e.g. 0.010 mm thick and 5 mm wide folded lengthwise, can be cut from a large piece of film material and wound onto bobbins prior to interweaving into panels.
