When selecting a bulletproof glass there are a number of factors to consider, these include the level of protection, the composition of the glass and the spall variant, the following aims to give some insight into the options available.
Bulletproof glass compositions vary but most common are laminated structures manufactured from several layers of glass bonded together with tough polyvinyl butyral (PVB) interlayer's.The performance requirements govern the number, and thickness of individual glass layers, thus affecting the overall thickness and weight.On impact the front layers of glass are designed to absorb the bullets initial impact energy by shattering allowing the subsequent glass layers and PVB to absorb the lower level shock waves.
