Much like security window films, laminated glass is often referred to as “shatterproof” and even “ bulletproof” while it actually falls into the category of “shatter resistant.” It’s manufactured by bonding layers of glass and interlayers together. They are often less expensive than laminated glass or polycarbonate panels, so they should not be expected to perform at the same capacity. Security window films are ideal in situations where the existing glass can’t be replaced. However, the shatterproof window films will not fully protect against ballistic attacks and do not provide as much defense against motivated criminals as some of the other options. Window films vary in thickness, with thicker films providing more shatter resistance. While they aren’t “shatterproof,” the film’s polyester layers will hold the glass together upon impact, protecting those inside from dangerous flying debris and slowing down invasion attempts. These films are transparent, resilient, and can also provide additional benefits of energy savings and UV protection to keep merchandise looking its best. This option isn’t actually a type of glass, but a film applied on the surface of the glass to add an extra layer of protection. These polycarbonate panels can be installed over existing glazing to provide an extra layer of protection 250 times stronger than glass, making it even more difficult to penetrate than the other options many cases, bulletproof as well. Often labeled as shatterproof glass but most certainly still breakable, laminated products are produced using glass combined with a polyvinyl butyral (PVB) or resin interlayer providing a reinforced glass much like the glass used in car windshields that will remain intact upon impact. These “shatterproof” glass films, applied on top of existing glass, are made up of multiple, micro-thin polyester layers designed to hold broken glass fragmenting together and improve overall glass protection. There are generally three options to choose from: Window Films The capabilities of the glass all depend on the type of reinforcement you choose. In addition to protecting building occupants from flying debris, reinforced glass can also prevent entry from bad actors like thieves and, in some cases, even prevent ballistic attacks. In fact, spall is one of the top causes of serious injuries that occur from natural disasters like hurricanes and attacks from bomb blasts. These shards can then be propelled at high velocities, which becomes a dangerous hazard to building occupants. When left untreated, the traditional glass in windows and doors will shatter into shards, called spall, upon impact. Whether you’re looking for a solution to protect windows and doors from smash and grab attempts or more severe threats like bomb blasts and natural disasters, it’s best to have a thorough understanding of what your options are and which provide the best protection for your needs. These subtle differences in glass types can help you choose an option that best suits your safety and security needs. It’s just a matter of how it breaks, such as the break pattern and if the glass will remain in the opening-or vacate the opening leaving the interior of the building vulnerable. In simple terms, virtually all forms of glass can break. There are a number of options available that sell themselves as “shatterproof glass.” But the issue with that term, shatterproof, is that many products that claim to be shatterproof are actually only shatter-resistant and can still be broken.
