Regular windows are made from float glass that will break into large, sharp shards of glass upon impact. This is a very dangerous scenario if flying debris and glass enter your home at high speeds, causing serious bodily injury. An opening in a hurricane is not only unsafe, but can likely cause extensive damage to your property from wind and water.

Impact windows are shatter-resistant and manufactured with 2 pieces of laminated, insulated glass that is bonded together with either Polyvinyl Butaryl (PVB) or DuPoint Sentry Glass Plus (SGP).  *Armored Impact Windows offers both options depending on the application.

After sustaining impact from a large object, the impact resistant glass may break, but should stay intact to the heavy-duty frame it is fastened to. Impact windows are designed to protect you and your home from wind, water and flying debris. Impact also must meet astringent standards, rigorous testing, and certified impact-resistant before they can be sold to market.
