The document discusses various architectural fabric materials for fabric structures, comparing their properties, pricing, and applications. Teflon-coated fiberglass (PTFE) is best for permanent, Class A structures due to its non-combustibility and 25+ year lifespan. Vinyl-coated polyester (PVC/PVDF) is most cost effective and accepts graphics best. Other materials discussed include ethylene tetrafluoroethylene (ETFE), high density polyethylene (HDPE), and various interior fabrics. The overall cost of a fabric structure depends on the fabric, required steel, finishes, and project size.
