Elite Armor BVG is a patented glass-clad, polycarbonate, multi-ply composite laminate, combing polycarbonate and glass using special polyurethane high adhesion bonding interlayers which allow the expansion / contraction differential of both materials. Our BVG glass systems are directly interchangeable with OEM (Original Equipment Manufacturer) parts. Replaces existing OEM glass window (standard vehicle window replacement) with a bullet resistant protective glass solution, with minimal modifications to the door, existing door mechanisms or window frame.
