Everyone is familiar with the concept of bullet proof glass. These types of glasses are transparent yet resilient to all forms of projectiles. These types of glasses are made by two forms of layers, one soft and one hard. The softer layer gives the glass its elasticity to prevent the glass from shattering. To keep the glass transparent and clear the index of refraction of both the layer is deliberately kept at the same level. Various types of Bullet proof glasses are available at the market today.
Acrylic: Monolithic acrylic is the most commonly used type of bullet proof glass. This product is made from a singular sheet of solid plastic with the measurements 1 1/4″ to 1 3/8″. They can be easily slotted, cut, routed, and grilled. These can be transformed into custom windows as well. These are transparent and allow light to pass through smoothly. The rough and cut edges can be smoothened by polishing which gives it an edge in terms of attractiveness from other types.
Polycarbonate: Though both Acrylic and Polycarbonate are good choices for level 1 to level 3 barriers, they are very different from each other. Acrylic is a rather harder product while polycarbonate is softer. When polycarbonate is used on its own to secure a bullet, it is generally laminated with layers. Also contrary to Acrylic, poly carbonate only allows 80% of light to pass through it due to its tilted nature. This can cause a little bit of a gloomy interior. One of the drawbacks of polycarbonate is that it is sensitive to ultraviolet rays.
Laminated glass: Laminated glass is known as the traditional bullet proof glass. Layers of resin and glass are crafted together to make this type of bulletproof glass. The glass has become pretty old-fashioned and rapidly is losing its market share because of a few serious drawbacks. These products are brittle and heavy which causes rigidity while drilling, slotting, or cutting them. This makes the whole process of smoothly incorporating into an “integrated bullet resilient system” very hard.
Ballistic glass: Insulated ballistic glasses are the new generation of bullet proof ballistic security glazing. These are “secure IG” units and were primarily developed for low-cost and not-traditional targets. For instance Schools, Homes, community centers and other residential areas use these kinds of glasses for additional security purposes. Secure insulated glass units are produced by combining various other glazings of best qualities. This type of glass is very good for both exterior and interior applications and maintenance is easier. Light transmission through it is also exceptional which results in a clear and not gloomy interior.
Glass Polycarbonate: GCP or the glass-clad poly carbonate is a modern makeover of the old and traditional laminated glass. The thickness of this kind of glass is typically maintained to be nearly one inch. Just like traditional laminated glass, GCP is also hard to integrate into acrylic seamless systems. One of the distinct features of this kind of glass is that all pieces have to be water-jet cut and hand polished around the edges by manufacturer for glass quality control purposes.
