  • Self-supporting pile, with built in ‘pile directors’, improves resiliency and reduces compression set
  • Solid polypropylene backing inserts more easily, saving time and reducing waste
  • Pile height and backing width are always uniform because of Ultrafab’s unique non-woven manufacturing systems
  • Ultra Pile® weatherseals have a structural integrity and consistency which assures a tight seal against air and water infiltration
  • No possibility of off-center pile that binds, breaks or stretches in an extrusion
  • Ultrafab’s unique ultrasonic welding assembles the fibers and backing into an integrated, unified assembly that won’t break apart during fabrication or while in use
  • Need a fin? Ask about Ultra Fin®, Ultra Soft Fin® or Tri-Fin®
