Hammerglass, which is made by specialists in Sweden, is times stronger than glass and is half the weight. It is available in 6, 8, 10, 12, 15, 17 and 20 mm sheets, and is recognised and licenced by Secured by Design and certified according to BS EN , Security Class P8B, which is equivalent to the highest safety rating for anti-burglary grilles and rolling shutters. To obtain this classification the glass must withstand 70 blows with an axe. In the case of Hammerglass, the Swedish National Testing and Research Institute gave up the test after 72 blows and then had to use a forklift truck twice to pull the axe out of the glass! Glazed doors and windows are the most vulnerable part of any building design. However, in the retail market, they are crucial to displaying merchandise as well as contributing to the overall aesthetics of a shop front.


Bullet Proof Home Windows

A modern bullet is a very small, very light, very smooth thing moving very fast. In terms of basic ballistics, firing a gun at a sheet of plate glass is very instructive. A 9mm bullet has a mass around 7. Mint specifies that, at production, a nickel is 5 grams and a penny is 2. These 7. Instead of being cast as a blob or ball, the lead is formed into a smooth cone designed to cut through a resisting fluid in this case air without being knocked off its path. When it comes into contact with a brittle, rigid surfacelike glassit transfers very little of its momentum to the surface, and instead pops through, like the little straw popping into a juice box.

No matter what weapon is used, no matter how many bullets are fired, bulletproof glass remains intact and unchanged. The strength and durability of bullet-resistant glass depends on how it is made and the thickness of the final product. Fire a bullet at a normal sheet of glass and the glass will shatter, right? So, how exactly does glass become bullet resistant? A single piece of acrylic with a thickness over one inch is considered bullet resistant.

Bullet proof windows for your home are the ultimate in home protection complemented with walls secured by ballistic material they can provide a completely secure home.

Forced entry through a window is a common entry point for burglars and potential attackers. Homeowners may invest significantly in secure doors, but weak glass can make those investments near pointless. Double pane glass may sound stronger, but even toughened glass can easily shatter in fact its safety features limiting sharp shards from forming makes it more susceptible to sudden bursting from attack by blunt object.

Ninja rocks are broken shards of spark plugs that are formed by smashing the ceramic portion of the spark plug with a hammer or other large object. Since they can quickly and quietly [1] [2] fracture the glass side windows on most cars, ninja rocks have been used in " smash-and-grab " auto burglaries since at least Tempered glass , which is used for the side windows of most vehicles, is manufactured with an extremely high surface compressive stress and high internal tensile stress, giving it strength and durability, but also leading it to abruptly shatter into thousands of tiny pieces when it breaks. When thrown with moderate speed at a side-window, a sharp shard of the exceptionally hard aluminium oxide ceramic used in spark plugs focuses the impact energy into a small enough area without blunting to initiate cracking, releasing the internal energy and shattering the glass. Legal records do not use the phrase "ninja rocks", preferring more precise phrases such as " ceramic or porcelain spark plug chips or pieces". Until , "burglary tools" in California did not include devices to break glass.

Bullet-resistant glass ensures suitable resistance to penetration from missiles of handgun, such as small arms or hunting weapons. Apart from bullet-resistant properties, this type of glass is a product characterized with increased break-in resistance properties, resistant to hits with such tools as a big hammer or axe. Bullet-resistant glass can be mounted alone or in combination with thermo-insulating, reflecting or fire-resistant glass. Splinter glass BR-S. Glass should provide its user with body protection against injuries caused by bullets or their fragments. Glass splinters can form on the protecting side of the glass. Non-splinter glass BR-NS.
