In a simulated seven-year weathering test, SuperScreen® lost only 1% of its original strength. In fact, it remained 3 times stronger than new fiberglass screen. SuperScreen® fabric includes a biocide compound that resists mildew growth, yielding longer lasting beauty from the fabric. The UV tolerant properties of SuperScreen® reveal themselves in the form of unsurpassed color retention, longevity, and filtering characteristics. With SuperScreen®, extended exposure to the sun will not result in the bleaching, flaking, and fading, like other screens. Fiberglass screen tends to get brittle with age and sun exposure, while SuperScreen® is virtually unaffected – which means it will look newer longer and save on maintenance.
