7 Glass Polycarbonate Ballistic/Bullet Glass This is a combination of glass and polycarbonate. The polycarbonate layer is bonded to the inside face of the bullet glass and that prevents the inner glass layers from breaking away and creating spall. This combination of glass and polycarbonate creates a lighter weight product and at the same time reduces the overall thickness of the bullet glazing. A comparative example would be between an all glass BR6 Non Spall glass (approximately 71mm thick) and a glass polycarbonate construction which again to BR6 would be around 38mm thick. The consideration when using glass polycarbonate ballistic glazing is that the polycarbonate on the inside face can become scratched and fogged generally through overzealous cleaning, particularly with abrasive cleaning products. The suggested method of cleaning polycarbonate surfaces is usually water with special attention to any additives that may be suggested by specialist cleaning product manufacturers. Spall allowed glass is a good alternative and using the above as an example then the BR6 Spall Allowed glass is 50mm thick and falls in between the BR6 NS and BR6 glass polycarbonate bullet glass. As with the BR6 NS ballistic glass it has a glass surface on both the attack side and also the protected side and therefore presents no problems when cleaning. The only time that real consideration may need to be given to Spall Allowed bullet glass is perhaps if it is used as a counter screen where the persons face is normally within around 450mm of the glass.
