31 DECREASED SOUND TRANSMISSION Unwanted outdoor noise is noticeably dampened with ImpactGard ™ glass. To compare, a single pane of glass generally has an STC rating around 27, a typical insulating glass unit has an improved STC rating of 31, and a laminated insulated glass unit can achieve an STC rating up to 35. The higher the STC rating, the better the sound dampening effects. Glass Interlayer Glass IMPACT RESISTANT GLASS Optional ImpactGard™ glass, which features a protective inner layer laminated between two sheets of glass, helps minimize structural damage by preventing windborne debris from breaching the building envelope (through broken doors and windows). In the event of breakage, most of the broken glass adheres to the protective inner layer or falls to the outside of the home. ImpactGard glass also helps resist forced-entry attempts involving breaking the window glass and decreases sound transmission from outside the home. SECURE FORCED-ENTRY RESISTANCE Windows and patio doors with ImpactGard ® protection help resist forced entry. Because the interlayer separating the panes helps resist a potential intruder's glass cutter, break-ins are less likely. SAFE IMPACT-RESISTANCE During a severe storm, a broken window can affect a home’s structural integrity. Windows and patio doors with ImpactGard ® protection are designed to help resist impacts so even if the glass cracks, the fragments will adhere to the interlayer, so the shards remain within the frame. ImpactGard protection also meets the nation’s toughest building codes. These codes specify that windows must withstand a nine-pound 2x4 traveling at 50 feet per second (34 miles per hour).
