Silicone sealants help provide building owners and tenants with increased security and protection. One dark night, burglars broke through the windows of a national retail chain store in Stuart, Florida, triggering the store alarm. Before police officers arrived, the burglars grabbed $35,000 worth of jewelry and disappeared. Store managers responded quickly to this "smash-and-grab" incident. They had the broken windows replaced and reinforced with more than 1,000 square feet of protective window film anchored to the window frames with a Dow Corning¨ brand silicone sealant. Just days later, someone used a heavy metal object to smash the glass on the store's front door: But the shattered glass remained adhered to the security film, the silicone sealant absorbed the blows, and the would-be burglar left empty-handed. Police found the broken window still firmly attached to the window frame. Silicones and blast protection In controlled bomb-blast application testing conducted by Dow Corning, 12 kilos of TNT were exploded 6.5 meters away from a 12 x 12-meter glass curtainwall panel structurally glazed on all four sides with a Dow Corning silicone structural glazing adhesive/sealant. While the glass broke during the explosion, the facade stayed largely in place, thanks to the strength and flexibility of the sealant. The new Lloyd D. George Courthouse in Las Vegas, Nevada, is a silicone structural glazing project designed to offer increased protection to building occupants in the event of a nearby bomb blast.
