Sika Flexitape Heavy Duty is an open polyamide woven fabric with a unique weave pattern which, unlike conventional scrims, is readily capable of stretching within the membrane to accommodate a high degree of thermal and structural movement. The special weave gives an elevated multi-directional elongation and is available in 50m rolls at 75mm and 150mm widths.
