Impact-Resistant Windows for a Storm-Ready Home (BV0104)

Bob visits PGT Industries to see impact-resistant windows being tested and assembled. Code Compliance Officer Dave Olmstead explains how windows break during a storm, allowing high-force winds to enter the home, pop off the roof, and cause catastrophic building failure. Impact-resistant windows are laminated to stay intact after impact so that wind cannot enter. Olmstead shows Bob the violent impact test used to certify windows to storm standards. He shows Bob windows made of standard annealed glass, tempered safety glass, and impact-resistant glass for comparison. A pneumatic cannon then fires a two by four at each of the windows. Traveling at 50 feet per second, the two by four completely breaks the annealed glass, penetrates the tempered glass leaving a hole, and bounces off of the impact-resistant glass leaving it shattered but held together with no holes to invite wind entry. Impact-resistant windows feature two panes of glass with a Buticite layer in between. The glass is pressure baked at 450 degrees for four hours before it can be set in the heavy-gauge frame with silicone adhesive. Bob watches the assembly process and learns that sales of these impact-resistant windows have risen 300 percent in the year since Hurricane Charley.
