All about the film for booking glass

Energy saving

Protective the film is almost completely transparent for visible light (light transmittance for glass with a protective film ~ 85%), but has a high reflectivity in ultraviolet and infrared range of radiation.

Therefore, the protective film serves as an additional thermal break between the street and the room, isolating them from each other.

UV and infrared protection

Reflection by UV protective film

Protection against infrared radiation and heat loss

The protective film reflects and absorbs solar thermal radiation, significantly reducing air conditioning costs premises in the summer. Glass surface with a protective film applied, capable of limit heat loss due to infrared radiation in winter up to 40%.

Protective film reflects up to 95% (when applied in two coats) ultraviolet radiation and protects the interior from burning out.

To increase energy saving, a protective film can be applied together with a mirror or tint.

Car glass protection

Auto glass protection can be conditionally divided into two categories:

1. Installation of full-fledged armor.
2. Bonding of the armouring film.

Glass armoring

Full armor

The installation of real armored glass is done by special order. As a rule, in such cases, the entire vehicle is booked. Armored glass is a multilayer structure with a thickness of 10 to 90 mm. There is a polymeric substance or polyethylene between the layers. Such a surface can withstand almost any impact and can protect even large-caliber weapons from bullets. It depends on its thickness.

In addition, bullet-resistant glasses are specially hardened. Cars with such protection are used in law enforcement agencies for military operations, in private security agencies, as well as for the transportation of high-ranking officials.

Protective film

Full armor provides reliable protection, but installation is very expensive, and it also significantly increases the weight of the car. A cheaper and more affordable option for every driver is a special booking film. The coating can be compared to tinting, but the material is much denser and thicker.

Armor film provides the following benefits:

• protects the glass surface from stones, road debris and sharp objects;
• partially increases the burglar resistance of the car, such glass is much more difficult to break;
• with a strong impact, the glass will not shatter into small pieces, but will remain intact;
• due to its transparency, after installation, the surface will transmit light at almost the same level;
• you can "close" not only the windshield or side windows, but also the headlights. Due to their proximity to the road surface, these elements are most often subject to impacts;
• increases the level of noise insulation in the cabin, but only if all surfaces are armored.

The disadvantages of booking include:

• the surface wears out quickly from dust and dirt, it is necessary to regularly monitor cleanliness;
• harsh cleaning agents can damage the film;
• if installed incorrectly, bubbles and folds appear.

Benefits of booking large windows

Modern architecture includes quite a few glass elements: often these are large display windows, front glazing, and other elements that occupy a rather impressive area. Glasses used to create such structures do not always meet high requirements for strength and safety, so they are easy to break, which can be used by intruders.

The armored window glass film will help protect windows and glass structures from tampering, minor scratches and major cracks. It preserves the glass, making it more durable, while not affecting the transparency of the structure, if it does not have a specially provided dimming.In addition, the film makes the glass itself much safer: if it is still possible to break it, the fragments will remain hanging on the film and will not fall on the floor of a residential or office space, which will not only greatly facilitate cleaning, but will also be able to protect people in the rooms.

Mounting

To obtain a high-quality and reliable armored coating, it is best to turn to experienced craftsmen who have not only theoretical, but also practical skills in working with the product. However, there are cases when you have to fix the film yourself. In this case, the following sequence of actions must be strictly observed:

• taking measurements of the booked object;
• making calculations;
• carrying out cutting activities;
• cleaning the working surface from dust, dirt and other types of contamination;
• applying a special soap solution to glass;
• installation of the selected type of film with the simultaneous removal of bubbles and excess liquid;
• removing all unnecessary fragments;
• drying the surface with an industrial or household hairdryer.

Violation of the technological process can provoke the appearance of the following defects:

• air bubbles;
• low level of transparency;
• reduced light penetration;
• violation of the integrity of the coating.

Experts do not recommend using a protective film in greenhouses, conservatories and greenhouses due to the fact that plants will lack solar energy. The modern world is a complex mechanism filled with various dangers and threats to life. In order to feel as comfortable and safe as possible both indoors and outdoors, experts recommend covering all glass surfaces with a special armored protective film.

In the next video, a crash test of 300 micron armor film on 6 mm glass is waiting for you.

Protective film against splinters

The protective film is resistant to mechanical damage: it is not destroyed and absorbs most of the shock wave energy during an explosion. The anti-shock film applied to the glass from the room side allows the glass to be shatterproof. During an explosion, in most cases, personnel are not affected by the blast wave, but by glass fragments. But with the applied film, this option is completely excluded, tk. the window film holds back the debris and prevents people from being injured.

When attempting to break, a protective film protecting the glass keeps it in the frame, preventing dangerous fragments from flying out into the room and preventing injury or harm to human health. Applying an impact-resistant film to the glass makes it shatterproof. And if the glass can be knocked out of the frame (for example, after many blows with a sledgehammer), then it falls entirely without breaking into sharp pieces.

The protective film allows the production of explosion-proof "shatterproof" glass. Often, after an explosion occurs outside the premises, visitors and personnel inside are not affected by the blast wave, but by dagger-like fragments flying inward. A protective window film, which is applied to the inside of the glass, holds back the debris after an explosion, preventing injury to people inside.

One-sided mirroring

Glass coated with a mirrored translucent film is one-sided visibility glass. In the daytime (or at night with additional lighting outside):

• from the inside of the room you can see everything that happens outside, the glass is almost transparent
• outside the glass is a mirror, it is impossible to see the room

Without bright lighting from the street at night, the opposite situation takes place: from the outside you can see everything that happens in the building, from the inside the glass is a mirror.

The principle of one-way visibility can be briefly formulated: against the background of a bright reflection, you cannot see a faint image passing through the mirror film from the inside. The degree of specularity of the film varies (for different films) from about 10% to 90%. The higher the specularity, the stronger the effect is.

Additional features

The same properties (strength and flexibility) give additional possibilities of using the protective film:

• According to the Ministry of Internal Affairs, any protective film on windows has the same difficulty of penetration as grilles, shutters, and blinds. In this case, it is possible to break the glass from the inside for the purpose of evacuation.

• Glass with a film withstands multiple throws of a 4kg steel ball from a height of 5-10m

• Fragments during explosions or impacts remain adhered to the film, do not penetrate through it

• Loss of time by an intruder to overcome the protective glass and the effect of unexpected resistance

• Protection against traumatic weapons and weakening the effectiveness of firearms

• by removing vibrations from the glass with a laser beam: the glass is less susceptible to vibrations

• Temporary preservation of the integrity of the glass. Evacuation guarantee: glass can be broken and knocked out of the room.

• Neutralization of "pops" of the window in case of accidental gusts and drafts.

• Strengthening the glass from accidental impacts and protection from splinters.

• Protection against ultraviolet radiation (and therefore fading of things) and infrared (thermal) radiation.

It is important to understand that most of the additional functions of the protective film are auxiliary and it cannot fully replace specialized glass (for example, fireproof or bulletproof)

Installation of the armor film

Film thickness ranges from 112 to 300 microns. For example, 100 microns is a tenth of one millimeter (1000 microns = 1 millimeter). Polyurethane is used for the manufacture of the material. It has unique abilities: it is very durable and elastic at the same time.

Installation of the armor film

Also, before installation, the density of the film is selected. It can be different. The higher the density, the less flexible the material will be. If the glass has a complex geometry, then a film with a lower density is selected.

Installation technology

Coating should only be entrusted to good professionals. The master will do the job efficiently and quickly.

First you need to prepare the glass surface. It is cleaned, degreased and wiped dry

It is important that there are no lint and dust on the glass, otherwise it will be noticeable. Then the film is cut to size.
Further, a special soap solution is applied to the glass surface and to the inner surface of the film.

With the help of plastic spatulas, the master gently expels air and liquid residues, gluing the material tightly.
The next step is drying. For this, either an industrial or an ordinary household hair dryer is used. It is important here not to overheat the material.

Installing the film

Booking cost

The exact price is difficult to establish. It will depend on the quality of the material, the thickness and area of ​​the glued surface.

On average, booking a windshield will cost 3000 - 3500 rubles. Covering two side windows - 2000 - 2300 rubles. Covering all side windows - about 7,000 rubles. Rear window - 3500 rubles. These are approximate market prices for an average passenger car.

Car glass armoring provides good protection against scratches, stones and impacts. Also provides partial protection against vandals and auto-thieves. A good and high quality coating will last for about two years. The armor protects the glass surface and can save you from costly repairs.

What is a protective film for?

Glass is durable but fragile. Therefore, upon impact, it easily breaks and shatters into sharp fragments.

The main properties of the protective film are strength and flexibility, thanks to which it resists pressure and shock well. The effect of applying it to the glass of windows can be compared with a newspaper on which an adhesive tape is glued: it becomes many times more difficult to punch such a newspaper with a blow.

Likewise, a thick protective film for windows is designed primarily to complicate glass breakingto which it is glued. And if the glass is still broken (the blow is too powerful), then the fragments will remain glued to the film, and will not scatter in all directions ("Shatterproof" glass).

What is a booking film?

Reserving window panes with foil can give different results depending on what type is used. The product itself consists of various polymer compounds, it is usually transparent, to improve its properties it has the thinnest layer of metal, which is invisible to the eye.

The thickness of the film may vary. If glass is coated with the thinnest material, it will withstand impacts from small stones. By applying a certain force, such glass can be broken, but the fragments will remain on the film, the broken glass unit will be easy to pull out and replace. When using a thicker version, the window can be protected not only from blows by small stones, but also from more serious impacts, for example, a hammer, crowbar, reinforcement, brick, ax blow.

Such a film will be useful not only for protection from a criminal element, but also from the elements, the clumsy actions of people in the room, children's pranks, in which the window can be accidentally damaged. The product is easily installed on any type of windows, regardless of which glass unit is used or which opening method is used.

What are the advantages of the product?

Reserving a double-glazed window will first of all prevent your property from being stolen. The offender will not be able to enter the premises by breaking the window. The method has other advantages:

Unlike roller shutters or grilles, films do not spoil the appearance of windows, they are completely invisible, do not attract attention and do not create inconvenience during use.
The material can resist fire, which increases the protective ability of windows.
Applying to glass is straightforward, even if you do it yourself.
Films protect well from sunlight, due to which furniture will not fade in the room, the wallpaper will not change color. Many indoor plants will feel more comfortable, the owners will not suffer from the heat in the summer, while the room illumination will not be affected.
The film will significantly reduce the noise level, since even a thick glass unit still has sound conductivity through the glass.
The decorativeness of the material allows you to refine the window, disguise it as stained-glass windows, if you use the color version.
The material protects well against splinters.
Even the thinnest film increases the strength of the glass by 4 times

If part of the surface is damaged, it is quite difficult to break the window completely; for this, an attacker must spend a lot of time, which will attract the attention of others.
The film can also be useful for glass repair. If a small crack has formed on it, and you do not want to change the glass unit, you can apply a film that will not only seal the resulting damage hermetically, but also prevent the crack from enlarging.

Protective films are a smart solution that allows, without spoiling the visual appeal of windows, reliably protect them from mechanical damage.

Anti-burglary protective film

The strength of glass with a protective film is increased many times over. It is difficult to break it even with many hammer blows. Even if the glass breaks, it remains “hanging on the film” without falling out of the frame.

Inexperienced Burglar or a bully can simply get lost when faced with a surprise and give up your attempt.

Planning theft or robbery experienced teacher, carefully calculates the time, which is required for penetration in the room. If there are grids on the windows, glass doors, he will either think of a way to break them in advance, or find another way of penetration. Glass surfaces with reinforcing protective films are indistinguishable in appearance from ordinary ones. When cteklo cpazu ne broken when attempting to penetrate, "vpemennoy gpafik" ppectupnika napushaetcya, B takoy ctpeccovoy cituatsii, if ye ocobenno cpabotala oxpannaya cignalizatsiya (voet cipena, migayut cignalnye mayaki, vcpyxivayut dopolnitelnye ppozhektopy) - ppectupnik navepnyaka otkazhetcya From namepeniya pponiknut Inside a pomescheniya.

In addition, thanks to the protective film and the additional time spent on overcoming the unexpected obstacle in the form of impact-resistant glazing, a regular patrol from the Ministry of Internal Affairs or police outfit (especially in the case of installing a security alarm) and promptly neutralize the offender.

V worst case come replace glass in a showcase or apartment: thanks to the protective film, the property will remain intact and safe.

Eavesdropping protection

The film cannot provide protection against all methods of surveillance and industrial espionage, but in some cases complicate or Prevent audio pickup from the glass.

A common hidden way (in addition to installing microphones) of listening to voices in the room is based on the fact that the reflected laser beam directed to the window glass (vibrating under the sound of speech) is recorded by sound. The sound signal reconstructed from the drawing repeats the conversation into the room.

When installing a protective and toning film, the level of vibration and glass reflection caused by acoustic waves is significantly reduced. It is very difficult to fix the vibrations of the glass with the applied protective film from the street, and it is almost impossible to highlight the sound signal in the received laser radiation.

Protective film structure

To achieve the required impact resistance class (degree of protection), a protective film is applied to the glass in one or several layers. Their thickness and quantity are selected empirically (depending on the required strength and the materials used), and then checked on certification tests. The total thickness of all layers of the protective film does not exceed 1 mm. Typically, an impact-resistant film is applied to glass in a layer of 0.2-0.6 mm.

Each layer of the protective film is itself a composition: protective liner + adhesive layer + leveling layer + protective film + anti-scratch coating.

Since the protective film itself is transparent, it is often glued to glass along with a film or film of variable transparency. "

Features and characteristics

Armor film is a protective coating that can be applied to all glass surfaces. The prototype of this material was armored glass, which manufacturers specifically install on a selected category of goods directly at the factory. However, the improved product increases not only the price range, but also several times the weight.

To reduce these indicators and simplify the installation procedure, the developers have released a special film for armoring glass. The basic raw material for the manufacture of this product is polyurethane, which is durable and elastic. Film density is measured in microns and ranges from 110 to 300 units. High-quality material must be manufactured in accordance with GOST 30826-2001.

The toning material has the following advantages:

• protection against all kinds of mechanical damage;
• preservation of the integrity of the structure during deformation and the complete absence of fragments;
• high level of light transmission;
• lack of visual obstructions and optical distortion;
• high level of fire safety;
• wide range of applications;
• soundproofing;
• lack of stratified areas;
• long period of operation.

Despite the huge number of advantages, experts recommend paying attention to the disadvantages:

• the need for regular cleaning;
• increased level of wear;
• impossibility of using aggressive cleaning agents;
• the complexity of self-installation.

Due to the high level of demand and universal purpose, experts recommend taking into account the following parameters when purchasing this product:

• climatic conditions of the region;
• the thickness of the product depending on the required level of protection and load;
• availability of quality certificates and permits;
• product quality and brand reputation;
• the presence of auxiliary effects.

Child safety protective film

A protective film is often used to reinforce translucent structures, which the child may have access to.

Any glass partitions, internal glazing of an apartment or cottage and other glass structural elements can be protected with an impact-resistant film.

The protective film will exclude the possibility of glass breakage as a result of careless behavior of a child near the glazing. And since the fragments are held by a protective film, they will no longer be able to injure the child.

The protective film is most effective when applied from the side opposite to the impact, therefore, in some cases, its properties are fully used: for example, when applied to a mirror (so as not to distort the reflection, the film is applied from the back side, on the amalgam) or when applied from the inside of the room to the glazing of windows or facade. For external glazing, in order to prevent falling out of windows, it is recommended to apply a film to the internal glass in the glass unit from the street side (in the air gap) - this can be done at the stage of production of the glass unit, before installing it indoors.
