Impact Hurricane Windows Technology

As you may already know, impact hurricane windows are cut from a different cloth than that of typical windows. Able the withstand the impact of flying objects without shattering, these windows make a case for themselves in communities that are subject to the plight of the Atlantic hurricane season.
Impact Hurricane Windows | Glass

The glass in an impact hurricane window is not actually a single piece of glass. Two pieces of glass are bonded together by a layer of Polyvinyl Buteral. It’s a resin that’s used for things that require strong binding, as well as optical clarity. While remaining totally transparent, it provides a powerful adhesive for the two pieces of glass. The main application for this is automobile windshields. Think about it. Road debris very rarely shatters a car’s windshield. There’s a reason for this. The windshield may crack, but would only shatter in cases of severe collisions. Basically, think of it like replacing all of the windows in your home with your car’s windshield. This is the same application for your home’s impact hurricane windows.
Impact Hurricane Windows | Resistance

During a hurricane, small objects and other debris are lifted from the ground by way of the storm’s high-speed winds. This is the reason why people cover their windows with plywood or metal shutters. With impact glass, there is no reason to do this as the windows themselves are tested to withstand the impact of a 9lb object being hurled at them.
Impact Hurricane Windows | Bonding

The strength of the bonding provided by the polyvinyl buteral has been time-tested. First introduced in the 1930’s, few other products have come about to challenge it as the predominant resin for its field. Only a few minor changes have been done to it over the years, with its current form being near-indiscernible from what it was 30 years ago.
