1. Virgin Foam Cores:
    While many competitors use regrind in their foam cores to save them money during production, Sunstar uses only virgin foam cores to save you money and provide you a stronger, more durable, and more energy-efficient cover.
  1. Antaeus 2000 Vapor Seal:
    Our exclusive, proprietary plastic is more effective than what other manufacturers typically use. Our specially formulated material reduces vapor transmission and still has the strength, flexibility, transparency, and seal-ability we require. Equally important is the perfect heat seal seam. Sunstar uses an impulse sealer that makes a perfect seam using the right combination of temperature, pressure, and timing. Unlike the less expensive hand-held sealing machines, all human variables are eliminated so your cover makes a perfect seal every time.
  1. N-ergy Fit™ technology and Full Length Heat Seal Gasket:
    Sunstar’s end pillow and full length heat seal are all specially designed to help save heat and prevent moisture loss for long-term energy savings.
  1. ASTM Cover Standard AND UL Classified:
    Sunstar meet the ASTM Safety Standard along with other manufacturers and we have gone a step further to be independently UL Classified.
