theft has long been to many craft.According to police reports often criminals get into the house through the window.Particularly high risk of being a victim of "burglar" owners of private houses and apartments located on the first and second floors.Given the current situation window manufacturers have developed protovivzlomny glazing.Let's talk about what it is, and whether or not anti-burglary windows protect from looters.

Features burglar windows
Any window consists of three main elements:
Previously, the glass was attached to the frame by fixing wooden stoppers or even conventional nails.To get into the apartment, the attacker does not even have to break the glass.With the advent of metal-plastic window glazing has become harder to get,
On the other hand, if the window is in the ventilation, enough to insert a piece of wood and to rest it in the switching mechanism, and then slammed.From mechanical damage blinker goes into "open window" and a thief can easily penetrate into the room.
As technology improved assembly of plastic windows as a window frame and mechanical fittings.It is possible to reduce to a minimum the possibility of penetration.However, to fix tight glazed and completely exclude the possibility of his hacking was only recently.
This technology is called "window-proof plastic."It combines the following components:
- reinforced fittings,
- specific mount glass,
- reinforced frame,
- multiple stiffeners.
Depending on the manufacturer, burglar fittings for windows made of:
- alloy steel,
- clad steel,
- conventional steel.
Titan is the most reliable material, other brands have both pros and cons, but no difference in principle.
Glazing in these windows is mounted directly to the frame, which eliminates the possibility of its removal by conventional methods.
reinforced belt inside the frame set is not all double-glazed windows, but where it is, the window of cracks in reliably protected from.
stiffeners provide additional protection and knocking out of cracks in the window.They are evenly distribute the load, resulting from whatever force the thief did not beat on the window, it will not be enough to shatter the frame.
Nevertheless, there is always an opportunity to break the window.Especially when it comes to private homes, where neighbors will not notice the background noise and did not react.But this problem is solved.
in resistant glass
more correct term - "shockproof" or "bulletproof" glass.The original technology was kept in strict secrecy and used exclusively in the US arms industry.Initially, these glasses equipped army cars and SUVs the first person of the country.
But, in the early 90s, shockproof glass became available to the general public.The secret of this material is quite simple.Whether it's a bullet, mechanical shock or blunt a sharp object, the surface of the glass is not broken and cracked, while maintaining integrity.
kinetic energy is dissipated evenly over the surface of the glass, in consequence of which there are many small, but deep cracks.If you continue to beat or shoot in the same place, it will take from 40 to 9000 minutes to penetrate the material.The difference in time is significant and depends on the quality of the glass.On sale is a serial sheets with a thickness of 2 to 17 cm. In addition, some plants produce armored glass on request.According
domestic GOST to distinguish between four main types of burglar glass:
- SPbSN 1 - 1.4 cm thickness, can withstand short-shot pistols,
- SPbSN 2 - 1.8 cm thickness, can withstand long-barreled shot gun,
- SPbSN 3 - 4.3 cm thickness, can withstand a shot Kalashnikov,
- SPbSN 4 - thickness of 16.8 cm, stands Dragunov sniper rifle shot, or M110 SASS.
Important: these types will not protect against armor piercing ammunition, they used a different nomenclature - class B1- B6.
While manufacturers of such products are many, according to experts and customer reviews most trusted enjoys Moscow firm AbavaTechnology.It not only produces its own products, but also offers a glass of German concern Silatec.The price of each particular product is negotiated with the buyer.
anti-burglary fittings for plastic windows
The above applies to new windows, but if you do not want to change the old, sufficient to establish quality fittings.In 90% of cases, this will stop the robber.Since a lot of security features, it is advisable to specify the general criteria to be brought to the attention of:
- mandatory use of closures with mushroom pins,
- mounting plates are made of steel or titanium,
- necessarily strengthen the lower hinge protective area,
- useprotective plates on the mechanical,
- handles reinforced lock mechanism.
All these elements are assembled by specialists in an already installed windows.It is important to entrust the work of a pro as self-installation does not guarantee the expected results.
For the convenience of customers, the manufacturers have developed a special anti-burglar windows markiroki system that allows you to quickly and easily find the right accessories:
- WK1 - the most inexpensive accessories that protects against tampering without using special tools, the efficiency of 5-10%, the average price of$ 50,
- WK2 - protects against the use of a screwdriver or wooden wedges, the efficiency of 7-15%, the average price of $ 80,
- WK3 - better protection that can withstand a break and the impact screwdriver, the efficiency of 20-25%, the average price of $ 100,
- WK4 - middle class defense mechanisms protecting against sawing and chopping tools, efficiency of 40-50%, the average price of $ 120-150,
- WK5 - reliable protection from the effects of the power efficiency of 70-80%, the average price of $ 200,
- WK6 - the most advanced class of protection, full protection even from the powerful electric tool and eliminates the possibility of penetrating into the apartment by hacking hardware, the average price higher than $ 300.
Prices are for a complete set of fittings, but if you want to buy them separately and to protect especially the most vulnerable places:
- lower hinge,
- window handle.
While hardware manufacturers in the domestic market are more than a few dozen, should be considered only three:
- Austrian company Mayer & amp;Co Beschläge GmbH products under the trademark of MACO,
- Turkish Grand KALE, not known for the high price of their products, which is 20-40% lower than competitors,
- French company ROTO, offering the widest range of hardware class WK1-WK4.
Since truly effective only WK5 and WK6, then the choice should stop at products MACO.Economy version - ROTO.Turkish fittings producer, usually installed in offices, because it does not always meets the stated standards.However, KALE much more reliable and durable than most other companies.
Another quality producer - an Italian company SPI, but in Russia it is presented very poorly.
Manufacturers burglar window profiles
most reliable option - is to buy all windows elements separately and assemble them in the nearest shop.So how about a glass and fittings it was already, consider manufacturers of window profiles:
- VEKA - German company, which is one of the first domestic manufacturer presented its products.However, the first does not mean better.The company has positioned itself as a producer of technologies available, therefore saving on the creation of window profiles.
- VINBAU - this is another German manufacturer.It is a financial investment company project GLAST GmbH, as a consequence, the manufacturer is more concerned about profits than about the quality.Despite this, the window profile is already equipped with a reinforcing frame.
- WINK HAUS is among the young, fast growing German companies.Zest - compactness and adaptability of production.Quality is achieved by reducing the composite node arrangements and increased durability parameters.Twelve-year experience has allowed the company to correct the defects of the primary projects and submit deustvitelno quality, unique product.
- REHAU - this is the most well-known German manufacturer of plastic profiles.This situation has two sides.Firstly, really high-quality window profiles and meets all requirements of the anti-burglar, and secondly, the wide popularity of the company led to the emergence of many low-quality fakes.
- KBE, although the Germans are the last on the list of their products deserve attention in the first place.The company specializes in innovative technologies that will positively impact on the quality and performance of products.
cost of the window frame depends on the size of the opening, the presence of the opening elements, connectors, complex geometric shapes.In addition, profiles of different types and chamber music, as well as some other parameters.Thus, the price ranges from $ 100-150 to $ 800-1200 per frame.
assembly burglar windows
in resistant windows, the price of which is at the level of $ 100-200 per package, in practice, will not protect against hacking.In addition, cheap fittings often breaks down and makes it difficult to use the window.Having considered particularly burglary protection advisable to make a few sample projects on which to make a start in choosing their own options:
- Create burglary protection already installed windows.Held in two phases.The ground must be inserted shockproof glass, the second - completely replace the hardware.It should be understood that the window frame is not reinforced, moreover, the installation plate spacing is likely to require the full repair.Without these elements of protection is effective only against ordinary robbers, who do not use a special expensive equipment.Fortunately for us, in most cases, law enforcement officers are faced with just such thieves.Glass SPbSN fit-1 or 2-SPbSN.Cosmetic repairs cost an average of $ 400-500, depending on the size of the window.
- Complete replacement of windows is more preferable, as it allows to fully protect against intruders.This option involves the purchase of a separate profile for the frame, glass SPbSN-2 and accessories.In addition, the work should be entrusted only to a professional team, particularly specializing in the installation of burglar windows.The total cost per box varies between $ 600-800.The only drawback - if the lock armored entrance door is equipped with the same high-quality security system, and the keys are lost, to get an apartment - it is impossible.
