Bullet resistant glass clad polycarbonate is a No-Spall product offering optimal protection in both interior and exterior applications. Bullet resistant, no-spall, glass clad polycarbonate is a combination of various layers of glass, polycarbonate, PVB (Poly Vinylbutyral) and/or a ThermoPlastic Urethane (TPU). Typically, a thin layer of glass is used on the exterior (threat side) surface to resist scratching or environmental effects. The interior (rear) face is always a polycarbonate layer with a scratch resistant coating. These various layers are bonded together and come as a single unit. All of our bullet resistant glass-clad products meet UL752 standards and are UL Listed for Levels 1 through 8.
