Criminals have been sprouting everywhere as a result of unemployment and the increase in cost of commodities. Thieves and robbers, outshine the rest of the criminals, making huge companies suffer from losses and expenses. Equipped with high-powered rifles, these burglars easily penetrate companies and institutions stealing everything that they can, and worse, hurting the employees of these companies. Seeing further potential losses and expenses, companies resort to installing bullet proof glasses as method of protection of their institutions.
Bullet-resistant glasses are designed to stop projectiles and limit or avoid splintering on the other side of the hit or impact. When a bullet is fired into the window, the energy impact is absorbed by the bullet proof glass, the energy of it may crack the window, however it will not penetrate through. Banks are frequent targets of armed robbery, and as a security measure, many have installed bullet-resistant glasses to protect their tellers from the criminal actions of the bank robbers. Other establishments that deal with large sums of money, like cash checking retailers and jewelry shops, also employ bullet proof glasses for protection against burglars.
These bullet proof glasses are used as a component in armored cars as they can withstand distinct rounds of bullets. Bullet proof glasses can entirely withstand hammers, axes, crowbars, and small-arm devices, however cannot endure an onslaught from high-powered rifles and weapons..
The composition and action undergone by materials greatly affect the bullet proof glass’s effectiveness, and for this cause it is vital to capture a gaze at the components that constitute up a material. Laminated glasses arranged in layers, thermoplastic, and polycarbonates are among the most common materials that constitute up bullet proof glasses.. When manufacturing bullet proof glasses, the producers are faced with one fantastic challenge, and that is to keep bullet proof glasses as identical as regular glasses, however must guarantee that its protective qualities are effective.. Bullet resistant glasses also undergo distinct processes, one of which is called tempering, where the glass undergoes a chemical action of cooling and heating, strengthening the glass.
No one would ever imagine a plastic, thinking that it cannot resist bullets, being one of the key materials in bullet proof glasses.. A plastic, when placed between layers of glasses deforms and absorbs the bullet’s energy and thus helps in preventing it from penetrating the glass and stopping it before it goes outside the other side. Other materials used in high-class bullet proof glasses are ethylene vinyl acetate, polyvinyl butyral and polyurethane; these are used in military vehicles and are thicker and heavier.. Looking at a bullet proof glass, one may reckon that it is equipped with complicated materials, however, it is simply made up of weak materials, that when placed together constitute up a stronger glass.
The protection level provided by a bullet proof glass is dependent on its properties and distinct conditions. One of the properties that have a fantastic impact of the protection level these bullet proof glasses provide is its thickness. These bullet proof glasses are usually seventy to seventy-five millimeters thick. The thicker these bullet-resistant glasses are, the more resistant they become. Bullet resistant glasses can also be affected by environmental factors such as Ultra-Violet radiation from the sun, temperature and exposure to certain solvents. Below zero temperatures can sometimes cause the creation of ‘spall’ on bullet proof glasses, these spalls are small pieces that break off the polycarbonate. Exposure to Ultra-Violet radiation affects Polycarbonate; therefore it should always be an under-layer in a bullet proof glass.. Protection levels rendered by a bullet proof glass vary depending upon its properties and conditions it is exposed to..
With the presence of high-caliber weapons of destruction, and armors against them, constant developments on bullet proof glass are still ongoing to date. In order to withstand the massive energy bullets can confer on bullet resistant glasses, it has gone through an evolution of different materials and methods for the purpose of perfecting it. Distinct innovations comprehend the creation of different kinds of bullet proof glasses. When two or more sheets of glass are bonded together with a plastic inter-layer, and subjected to heat and pressure, it results in the complete adhesion of the vinyl and the glass; this then forms a Laminated Glass..
A Laminated Glass can be dense to penetrate since it contains a resin, polyvinyl butyral, which has strong tenacity, and can absorb and weaken a mass of striking energy, that much if it is broken, the splinters will stick to the interlayer and not scatter. Acrylic, another form of bullet proof glass, is a dense and clear plastic that resembles glass. An acrylic whose thickness measures more than an inch can be considered as bullet proof.. Weighing fifty percent less than a glass, stronger and more resistant, acrylic is lighter than a glass..
An innovation that came after acrylic was Polycarbonate, a bigger type than acrylic.. A Polycarbonate is another bullet resistant glass made of weak materials however has unbeatable strength.. Polycarbonate is effortless to deal with since it is three times lighter than acrylic, and six times lighter than the weight of a glass.. Polycarbonate is combined in layers to constitute a bullet resistant glass. While acrylic repels bullets, polycarbonate catches the bullet and absorbs its energy, preventing it from exiting outside the other side. Glass-Clad Polycarbonate Bullet-Resistant Glass, a more innovative type of bullet proof glass, uses a combination of materials to constitute the desired result.
Glass-Clad Polycarbonate Bullet-Resistant Glass is composed of a piece of polycarbonate material sandwiched between ordinary sheets of glass heated, and then cooled, molding the materials together into one piece, forming a material that resembles glass however is thicker and more durable. Thickness plays a huge part in the ability of a glass to resist bullets. Bullet-resistant glasses are designed to remain intact for one bullet or one round of bullets depending on the energy of the bullet being fired and the type of weapon used.
Bullet-resistant glasses are usually rigid, however may be supple, and they may either be simple or complex depending upon their composition and the processes undergone. Bullet proof glasses are often used in code enforcement, military applications, and institutions that are appealing to burglars. These protective glasses serve as shields, protecting employees, consumers, and personnel from death or serious injuries, however, the protection rendered may vary depending on the type of bullet proof glass used and its properties.
Up to date, there is still no innovation that is completely resistant to use of heavy weapons and transparent at the same time, but bullet proof glasses can somehow prevent burglars from easily breaking in.
