Super Screen creates an outdoor fabric enclosure that is tear and puncture resistant and 300% stronger than fiberglass screen. The fiberglass screen material can become brittle within 3-4 years and can be easily damaged by pets, flying debris or children. Super Screens advanced polymer formula defies deterioration and resists mildew grow. In a simulated seven-year weathering test, Super Screen lost only one percent of its original strength. It actually remained 3 times stronger than new fiberglass screen. Super Screen has a life expectancy of more than 10 years and is backed by 10-year limited warranty.
