The Simonton Reflections 5500 line is Missile C impact-resistant certified. Windows and patio doors with SafePoint impact-resistant laminated glass are appropriate for inland coastal areas where Missile D certification is not required and wind speeds are less than 140 mph. SafePoint glass is crafted from a durable interlayer sealed between two layers of glass. To pass certification, glass must resist breaking when hit by a four-pound, 4-foot-long, two-by-four piece of lumber shot at 40 feet per second (27 mph).
