Two types of fabric are available: polyvinyl chloride (PVC) and high-density polyethylene (HDPE, or simply PE). PVC fabric has long been used with fabric structures and is a long-lasting choice. PE fabric allows for greater translucency and typically a lower cost. Both types of fabric are available in a variety of colors, as well as an optional flame-retardant finish.
Structural fabric is composed of three layers: an inner woven layer, called scrim, and a polymer coating that protects the scrim from UV and heat damage.
Fabric is non-corrosive, even in harsh environments. Fabric is the only building material that allows diffuse natural light to penetrate the walls and ceiling of the structure, eliminating the need for artificial lighting during the day. Fabric is climate-responsive, keeping the interior of the building up to 10 degrees cooler on hot days and about 5 degrees warmer on cold days – even before adding insulation and climate control.
With Legacy’s patented attachment system, each fabric panel is individually kedered. The keder system keeps the fabric out of contact with the steel frame, minimizing friction and prolonging the life of the fabric.
