Bullet-proof glazing offers protection as well as visual feature for individuals. This type of bullet-proof material is frequently used in bank teller cages, other types of service counters and even armored vehicles. Apart from that, there are different types of bullet-proof glazing individuals can choose from. Below are some of the following.
Laminated glass consists of multiple layers of glass laminated with protective interlayer, usually polyvinyl butyral. As of now, it is the most inexpensive type of bullet-proof glazing. And, it is also scratch resistant. However, laminated glass are quite heavy, so special structural considerations are required.
Acrylic is another common bullet-proof glazing option. It weighs only half of laminated glass, but it can scratched easily and it is only available in lower ballistic ratings.
Polycarbonate is ideal in preventing incoming bullets as well as prevents ricochets and spalling. Sadly, polycarbonate is more expensive than laminated glass.
Glass-Clad Polycarbonate consists of polycarbonate with a layer of glass added to it. The glass side resists scratching and provides weather-resistance and it offers protection against physical attack. One of its main down side is visibility since it has slight grayish tint not as clear as glass or acrylic.
