Make armored glass. Pros and cons of booking a windshield with a film

The process of coating the glass of a car from the inside with a thick film that provides protection and strength is called glass armoring. This coating withstands the impact of a hammer, bats and other heavy objects. The booking system itself came from a business. The earliest films were invented for industrial buildings and commercial premises where protection against robbers and vandals is necessary. In this article, you will learn how to apply such a film yourself, what advantages and disadvantages this system has, and how effective it is.

Film varieties

There are different armored films designed for:

  • Autoglass. Thickness from 250 to 310 microns. Free sale. Glued on the principle of tinting. It will take 1 month for complete drying. After that, the film withstands blows with a stone, a hammer, a bat. It saves the car and its passengers both from stones that can fly off on the highway, and he also robs.
  • office buildings. Thickness, as well as at a film for an auto glasses. Suitable for offices, shop windows, workshops, large shopping centers. Rolls of material are much larger in width than for auto glass.
  • especially important objects. Thickness is about 550 microns. This is necessary for especially important facilities in any state in order to protect themselves from possible terrorists. Such glass is absolutely impossible to break and penetrate into the room.
  • Bulletproof for auto glass. Withstands shooting not from any firearm. The standard film is bulletproof, capable of withstanding .38 caliber bullets from a pistol. The thickness of the glass must be at least 12 mm, as well as multi-layered, exactly like the windshield of a car. Automata, this reservation will not be able to withstand.

Whatever the booking film, it is difficult to give a 100% guarantee of strength. The name "bulletproof" is conditional. Studies have shown that this glass will not break through if they shoot from a pistol of the specified caliber and into different parts of the glass. In the event that bullets of the required caliber hit the same place, the glass will be pierced through and not a single film can save it.

Pros and cons of booking a windshield with a film

Often, car enthusiasts believe that car tinting and booking are related to each other. In addition, there is an opinion that such a windshield coating will impair visibility and interfere with driving. All this is completely wrong. The main features and advantages of such a film:

  • Quality visibility;
  • Does not mix with tinting;
  • Perfectly tolerates auto chemicals;
  • A thick film covers the windshield, a thin film covers everything else;
  • Coating with polarized film - reducing glare;
  • Uniform distribution of impact;
  • Protection against petty vandalism.

It is also worth remembering about the headlights, which also need protection from foreign objects.

Before you go to the service station, it is important to know the disadvantages of film booking:

  • When driving or parking, dust settles on the surface of the windshield. When the car owner turns on the wipers, significant damage is caused to the film in the form of scratches. To reduce damage, avoid heavy dusting and wipe the windshield more often.
  • Bubbles can appear anywhere. If they appear in front of the driver's eyes, they will usually be very annoying and reduce the quality of visibility. In addition, the appearance of the car suffers.

The price of booking car windows with a tint film starts around 3,500 rubles.

DIY booking

Glass armor is usually used by motorists who have become victims of broken glass for any reason: someone because of the stones that often fly off the wheels, and someone because of a robbery.

The appearance of the film is similar to tinted with the highest level of transparency. You can buy it in auto stores or through online stores. The procedure for applying the film is as follows.

1. You need to remove the side windows. It is necessary to follow everything according to the instructions based on the make and model of your car. You should carefully get to the latches and remove the glass, before that, do not forget to unscrew the door cards.

2. Removal of dirt and grease. An important point is the degreasing of each glass completely. To do this, lay the glass on a pre-cleaned flat surface. Be careful with abrasive particles that can scratch the glass. Next, you should clean the inside of the side glass, where the booking film will be applied. To clean it, you can use a glass cleaner and a lint-free cloth. It is important to understand here that any dust or lint, if it suddenly remains on the surface of the glass, will not remain under the film at all, and the view of the glass from the inside of the cabin will be far from aesthetic.

3. Preparation. The film itself consists of an adhesive layer and a protective colorless substrate. First you need to measure the glass and cut off the required amount of film with a margin.

4. Now apply to the clean inner side of the glass. The film must be positioned so that the substrate is at the bottom. Using masking tape, you can perfectly fix the film on the glass. Make sure that there is at least 1 cm of film peeking out from all sides.

5. Preparation of a special agent for removing the adhesive part from the film. For cooking, you need to take plain water and liquid soap. The proportion is 20% soap and 80% water. Shampoo should be used with minimal fragrances and additives. Otherwise, these additives will most likely enter into a chemical reaction with the adhesive layer, which will turn out to be unknown. The resulting solution must be filled with a garden sprayer

6. We glue the film and smooth it. Carefully remove the protective backing, keeping the foam only where the edges will not come into contact with the glass. Pour the prepared solution over the surface of the glass and the adhesive layer of the film. Now you should attach the armored film with the sticky side to the inside of the side window. On the first film will go on the surface, and this is necessary to smooth out the bumps with a special mini-spatula (it can be changed to a bank card). With simple movements from the center to the edges, it is necessary to expel all air bubbles. If this is not done, then bubbles will form, which will no longer be possible to remove.

7. Drying with a building hair dryer. After straightening the entire film, it must be thoroughly dried with a hairdryer. It has a high air t and a thinner jet. The hot film will be able to stretch over the surface. Then take a break for an hour so that the film has time to cool.

8. Removing excess. Initially, at least 1 cm extra was left in order for the film to be enough. Now that it has sat down well and cooled down, you can cut off the extra parts with a clerical knife. It is best to hold the knife at an angle of 45 degrees. It is also desirable to hold the film with a spatula.

Final drying lasts far from one day. The highest degree of protection will appear in a month. Based on experiments, it is possible to break through glass with only 4-5 hits in one place with a heavy object.

Outcome

Thus, armoring car windows with a film very well protects not only from foreign objects flying from under the wheels, but also from possible robbers and vandals. But, as a rule, car owners begin to think about it only when something like this happens and the glass is damaged.


How is bulletproof glass made? Interested in the production technology of bulletproof glass!

The history of bulletproof glass began in 1910, when the French scientist Edouard Benedictus invented a method for producing extra strong glass by placing a special celluloid film between two glass sheets. Such glass, now known as laminated glass, was patented by Benedictus under the name "triplex". However, do not expect to sit behind bulletproof glass during a serious shelling. Absolute armor that protects against all firearms simply does not exist, especially armor made of glass ...

Triplex is the most reliable and safe glass. Over the century that has passed since the Frenchman made his landmark invention, the glass industry has gone far ahead, and now the triplex manufacturing technology is approximately the following. Two sheets of tempered glass are glued to each other over the entire surface with a polymer film or a laminating liquid. (By the way, she herself worked at the Macromer Research and Production Enterprise in the production of such a liquid - indeed Gin is right, this is Acrolat: http://www.macromer.ru /him.shtml?base=5&...) Moreover, sheets can be made of glass of both the same and different types, they can be straight or bent (they are shaped before gluing). Lamination itself is a rather complicated process, it is carried out on an automated line in several stages. At the last stage, the glass sheets enter the autoclave, where the film polymerizes at high temperature and, like glue, connects the glass. As a result, the impact strength of conventional triplex is 10–15 times higher than that of conventional sheet glass. If the triplex still manages to be broken or pierced by a bullet, the fragments will not splash in all directions - they will hang on the intermediate film without causing harm. Such laminated glass looks like a monolith.
However, a polymer film can glue not two glasses, but more. But a three-layer triplex is still considered the best option - further addition of layers significantly increases the cost of the product, although, of course, the protective properties also increase. But by and large, it makes sense to use multilayer triplexes only where there is a serious threat to human life or to material and museum values.

But safety can be ensured not only by the use of triplex. There is also an alternative method of strengthening and protecting glass in glass structures in buildings - gluing window films onto ordinary high-quality glass.
Professional window films (such as US Courtaulds Performance Films), when applied to glass, avoid the risk of splintering. Glass reinforced with such a film successfully withstands even a shock blast wave - and if it is damaged, it will remain in the frame or fall out in a whole piece without scattering into sharp fragments.

The US Air Force is testing a new transparent material that could soon replace bulletproof glass in military vehicles. Aluminum oxynitride (ALON) is a transparent material similar in optical and structural characteristics to sapphire. It is very strong and much lighter than regular bulletproof glass.
The windshield, which consisted of three layers (ALON, glass, again ALON), during tests successfully withstood, for example, shelling with armor-piercing cartridges from an M-44 sniper rifle. Normal bulletproof glass needs to be several times thicker than an ALON windshield to withstand a similar load.

Hide

Armored windows are widely used in various fields: they can be found in banks, residential buildings, shops, cars. The design is a thick glass made of triplex and polycarbonate. The layers are superimposed on each other and glued together in a special way, due to which a thick, heavy, but very strong structure is obtained.

Product varieties

Armored glass is similar in properties to tempered glass. Read what is the advantage of this type of glass.

Using an armored window

Not so long ago, armored windows were used exclusively in places associated with material or historical values, such as museums and banks, but later armored windows became more affordable, and it became possible to meet them in ordinary private houses, and not necessarily government officials.

Modern windows have become much more technologically advanced, more affordable and more functional. They can be installed instead of . Armored windows for the home are superior to standard double-glazed windows not only in terms of strength, but also in all other indicators, such as protection from cold and noise.

What should be considered when buying an armored window?

Before you buy armored windows in an apartment, you need to determine what you need it for. You may not be able to get by with the cheapest option that can withstand the impact of a stone, or you may not have to pay extra since you do not need a bulletproof window.

Product functions may be as follows:

  • Protection against stone ingress, accidental mechanical damage.
  • Security from criminal encroachments, attempts to purposefully break a window.
  • Protection against shots from firearms.

The difference between the designs lies not only in strength and cost, but also in functionality.

Possible options when choosing a window

Reservation of double-glazed windows with a film makes them more durable, triplex glass does not spill out when broken, since all the fragments remain on the film. Such a strong desire can be broken, but it will take a vandal quite a lot of time. Bullying teenagers can not be afraid. Glass can prevent a thief from getting into the house, it will last much longer than usual, but it will not provide protection from a bullet.

Armored plastic windows for a house are most often an ordinary triplex that fastens several thin glasses. It makes the window stronger and safer, but such a product cannot be fully called armor. A double-glazed window of such a plan is suitable for standard plastic frames and is inexpensive.

Types and designs of frames

Bulletproof double-glazed window is quite an expensive pleasure, but it can be of different options, from one relatively thin glass to a thick complex. It is worth noting that the lowest-class double-glazed windows can freeze and produce condensation. Thicker double-glazed windows will cope with a shot from a more powerful weapon and hold heat better, but they will weigh quite a lot. The higher the class of double-glazed windows, the stronger it is. To make it clear, a class 5 product can withstand a shot from a 7.62 caliber.

Armored windows in the house can be of different designs and meet different requirements and standards, which affects their thickness and price. Such windows are quite affordable to a wide range of buyers.

Armored windows or how to secure your home in the 21st century

Armored windows for the home are already beginning to cease to be something unique and inaccessible. Today's realities show that only with their installation you can gain confidence in the absolute protection of your own home. The year is 2016, and if you don't want to fall prey to today's offenders, then you need to keep up with the times and be aware of the latest security practices. I will try to give you enough information for this.

Reservations against bars

The owners of window bars can answer that, they say, they have already sufficiently taken care of the safety of their homes, and they do not need expensive window armor at all. Then I recommend paying attention to the significant disadvantages of using steel barriers, which armored glasses are deprived of:

  1. The presence of vulnerabilities when trying to hack. As I mentioned above, now it is already the 21st century in the yard and attackers are armed with not only a crowbar and a set of master keys. For example, to eliminate steel bars, liquid nitrogen can be used, with which the task will be solved quickly and silently;

  1. No bullet protection. The metal honeycomb construction will not stop bullets or small fragments. Is there anything that can happen on the street? Recent unfortunate events in Europe have shown that even the most prosperous areas can be at the epicenter of the situation with the use of firearms and explosives;

  1. Panoramic view violation. Even beautiful forged products are not able to completely eliminate the oppressive feeling of the sky blocked by steel;

  1. Reducing the level of fire safety. Deaf gratings not only do not let anyone in, but also do not let anyone out, which can play a fatal role in the event of a fire or other emergency. And even if a swing-type design with a lock is used, then, again, it will also take precious seconds, or even minutes, to search for the key.

The price of armored windows, although much higher than forged ones or bars, they are:

  • Not hackable methods available to most robbers;
  • Protect not only from penetration, but also from bullets and shrapnel;

  • Will not affect the panoramic view in any way, as they have absolute transparency;

  • Won't be an obstacle if necessary, an urgent exit through the window opening.

As you can see, the differences are very significant in order to think about the possibility of allocating sufficient funds for the purchase and installation of armored double-glazed windows.

Booking Options

There are two ways:

  1. Purchase and installation armored double-glazed window;
  2. Booking window glass special film.

The first is undoubtedly more reliable and allows you to achieve maximum security, and the second, on the other hand, will cost less and can even be done by yourself, although the process itself is quite complicated. I'll take both:

Armored double-glazed window

To ensure the absolute impregnability of your window opening, of course, it is necessary to install a fully armored window, that is, not limited to strengthening the strength of glass alone, but also guarantee the resistance to mechanical stress of the frame itself.

Thus, we can talk about two components of the whole structure:

  1. laminated glass reinforced with polyvinyl butyral film or polymer filling;

  1. Multi-chamber profile frame with hardened steel inserts. At the same time, the appearance of the window is the same as that of a normal one.

When buying such a miracle of modern technology, ask how protected the joints of the frame with glass are, since they are the most vulnerable places in this design and must be covered by the "stuffing" of the profiles. Otherwise, the level of protection of the entire double-glazed window can be considered incomplete.

Previously, glasses were strengthened exclusively by pouring polymers into the gaps between them, now the use of PVB films is becoming more widespread. Why? To answer this question, it is enough to make a comparative description of some parameters of finished products:

  1. Chroma:
    • With PVB, full transparency is guaranteed without the appearance of any shades for ten years;
    • When pouring polymers, yellowness may appear already in the first operational year as a result of exposure to ultraviolet radiation;

  1. Optical distortion:
  • When PVB is completely absent;
  • When pouring polymers, it is possible if the substance is distributed unevenly;

  1. bundle:
  • When PVB is completely absent;
  • When poured over time, it occurs due to a weak level of adhesion between polymers and glass;

  1. Loss of protective functions:
  • When PVB does not occur for at least ten years from the start of operation;
  • When pouring gradually carried out;
  1. Increase in thickness:
  • At PVB the minimum;
  • Noticeable when filling.

As a result, I concluded for myself that if I order bulletproof glass, then only those that are reinforced with polyvinyl butyral film. The cost of such double-glazed windows depends primarily on the protection class:

  • 2nd class:

  • 3rd class:

  • 5th grade:

  • Class 5a:

  • 6th grade:

  • Class 6a:

Reservation of glass with a film

Booking windows with film, as I noted above, is much cheaper. So, for example, if you order such a service from the appropriate company, then everything with work will cost you from 1000 rubles per square meter, which is many times cheaper than installing armored double-glazed windows. Of course, such a barrier will not save you from snipers, but it’s completely from breaking and even shrapnel.

Here is a classification showing the level of this protection method, taking into account the thickness of the glass, as well as the thickness and number of film layers:

Armored film on window panes can be installed independently. At first glance, the task does not look very difficult, but in fact it has a lot of "pitfalls", for the successful overcoming of which it is necessary to have at least some experience.

If you have doubts about whether you can handle glass armoring on your own or not, then it’s better to seek help from qualified specialists, or at least practice on a small window somewhere in the pantry or in the garage.
Otherwise, you run the risk of simply spoiling the applied material itself, the cost of which starts from three hundred rubles per 1 m 2, and the processed double-glazed window, which will cause much more damage to your family budget than paying for hired services.

The very same instruction for booking glass, which I used, looks like this:

  1. Measured glass using a tape measure. To the data obtained, I added 10 mm on each side for cutting, but if you have them without a frame, then 5 mm will be enough;

  1. Performed calculations in relation to a roll, the standard width of which is 1524 mm;
  2. On the big table made an accurate cut canvases;
  3. Prepared a solution by adding a few drops of shampoo to half a liter of distilled water;
  4. Attached the cut fragments of the film to the glass by checking the match. In case of a positive result, proceeded to further operations;
  5. I applied the mixed solution to the glass and carefully cleaned it with a scraper from dirt., after which he removed the remnants of foreign particles from a smooth surface with a special wash;

  1. I repeated the procedure several times, achieving absolute purity. The fact is that getting the smallest grain in the gap between the film and glass can ruin the whole work;
  2. Wetted the first fragment of the coating on both sides to prevent dust from getting on the adhesive layer and removed the lavsan from it;
  3. Then again applied the solution to the side with glue and attached it to the glass;
  4. The outside was also treated with the prepared liquid, after which with a yellow squeegee drove all the water out from under the film;

  1. Trimmed the excess edges with a sharp knife;
  2. Removed leftovers;
  3. I left the coating to dry. During this period, there is such a strong connection of the film with glass at the molecular level that they become one.

Depending on the thickness of the applied material, the time for its complete drying also varies:

Conclusion

Metal, wooden and even plastic armored windows will become a reliable guarantee of its safety for your home. If their cost is too high for your family budget, then you can stop at booking glasses by applying a special protective film. It will come out much cheaper and will also be able to provide quite a decent level of protection.
