Astroguard is a resin-coated hybrid fabric that is 2.5 times stronger than polypropylene, providing unmatched protection from hurricanes. AstroGuard provides “full envelope” protection of your home or commercial property, deflecting hurricane-force winds and preventing pressurization of the home. This pressurization is what causes roof lift-off during a hurricane and catastrophic damage to the home. AstroGuard weighs just ounces per square yard and gives homeowners and business owners the peace of mind knowing that their property, belongings, and families are protected.
