What types of double glazed windows are there for plastic windows?

Since ancient times, people have tried to protect their homes from the encroachments of strangers. Time passes, and to this day it has not been possible to invent perfect protection for a protected premises. The window is still the most vulnerable to an attacker getting inside.

However, today there are already technologies that can be used to minimize the likelihood of an outsider entering the room through a window opening. One of them is to install a modern window, plastic or wooden, the glass unit of which is endowed with impact-resistant characteristics.

The existing most effective types of window protection:

• Triplex system.
• Special protective film.

Triplex technology. Description.

Unlike a conventional double-glazed window, the triplex window protection system includes in its design two glasses glued together with a reinforced film, 3 or 4 mm thick. This technology has its own formula, which allows you to easily navigate the characteristics of the material used. For example, a value of 3.1.3 says that a reinforced film 1 mm thick is laid between two 3 mm glasses. Accordingly, the total thickness of the glass installed in the double-glazed window will be 7 millimeters. You can easily determine another protective solution, the basis of which is 4 mm glass - 4.1.4.

The impact resistance of the triplex structure is such that it allows the glass to maintain its shape even with a strong impact, although it is worth noting that in this case it can “become like a mesh.” Using a crowbar will only leave a hole in the glass. In order to finally get rid of the fragments, you will need to make a lot of noise, spending a lot of time and effort.

A limitation on the use of the Triplex system is its weight. This solution makes sense to use on small doors or when it is necessary to provide increased noise insulation in the room.

Possibilities of impact-resistant double-glazed windows

Double-glazed windows with impact-resistant glass can significantly expand the possibilities of modern construction, providing adequate strength to structures with large dimensions.

In modern translucent structures, double-glazed windows with combined impact-resistant glass are widely used:

• tempered glass reinforced with film
• triplexes made of tempered glass
• triplexes with several layers of PVB film
• triplexes with three or more laminated sheets of glass

Protection class A3.

Today, class A3 protection coatings are the most durable. Therefore, their use is limited to a narrow range of protected premises: banks, car services, etc. They can withstand energy equal to 362 J, that is, a blow from an object weighing up to 182 kg (about 70 blows with a fire ax).

Making a comparison between the “Triplex” glass protection technology and the effect of shockproof film, it is possible with formula 4.1.4, that is, a thickness of 9 mm, approximately corresponds to armored film of protective class A1.

To ensure comprehensive window protection, in addition to double-glazed windows with the Triplex system or armored glass, special anti-burglary fittings, as well as security roller shutters, should be installed on the window.

   My window faces the visor. I didn’t understand from the article what I should choose and how much this pleasure would cost me. Of course, the valuables I have are valuable only to me, but still...

   Answer

Advantages of impact-resistant double-glazed windows

• Wide possibilities in ensuring burglary resistance and security of translucent structures.
• The possibility of destruction of impact-resistant double-glazed windows by children or pets is unlikely.
• If destroyed, they have a low degree of injury risk.
• Double-glazed windows with impact-resistant glass provide a high degree of sound insulation of rooms.
• In suburban construction, impact-resistant double-glazed windows are a complete alternative to window bars.
• Possibility of combining impact-resistant and other types of special glass in one double-glazed unit.

The difference between double-glazed windows depending on the gas used to fill the chamber

The main properties of a double-glazed window - thermal permeability and sound insulation - largely depend on the gas that is pumped into the chambers. Light transmittance practically does not depend on this - the main role here is played by the characteristics of the glass itself.

Dry air is pumped into ordinary budget-level double-glazed windows; it has fairly low thermal conductivity, high transparency, and its chemical composition does not differ from atmospheric air. More expensive double-glazed windows use argon, krypton or xenon - inert gases that are completely harmless to humans. There is no need to fear that if the sealing layer is damaged, these gases will penetrate into the room. Even if this happens, they do not pose any danger.

The price of such double-glazed windows differs somewhat; it depends not so much on consumer properties as on the cost of gas. The cheapest is argon, the most expensive is xenon. Inert gases exhibit their main qualities when used in double-glazed windows equipped with energy-saving glasses (i or K). But even with ordinary glass, some indicators improve, although the changes are not so pronounced.

Useful qualities of inert gases:

• reduction in thermal conductivity coefficient;
• reducing the risk of condensation;
• protection of internal i-spraying from oxidation.

But despite the obvious advantages, double-glazed windows filled with inert gases are not without disadvantages. The main one is that the gas must be pumped under pressure above atmospheric pressure. This requires increased strength of the sealing layer at the end of the glass unit. The high penetrating ability of the inert gas determines its leakage through the slightest seal defects. Even in the best double-glazed windows, up to 3% of gas evaporates per year.

The average effective service life of an energy-saving window filled with inert gas is 10 years; after this period, the glass unit must be filled with gas again. This is associated with some inconvenience and unnecessary costs.

In addition, there is another risk factor - inert gases are odorless and colorless; it is extremely difficult to determine what exactly is pumped into your window. If you buy an expensive window from a trusted manufacturer, then you can be sure that the chamber contains inert gas. But in other cases there is no such 100% certainty.

How to decipher information from markings

Alphanumeric markings contain basic information about the glass unit. To avoid being deceived by unscrupulous sellers, it is important to be able to read the glass unit formula. It can be applied to a sticker on the glass unit, on the spacer frame, or contained in the accompanying documentation.

The marking provides information about the main characteristics of the glass, dimensions, presence of films and coatings, and type of gas filling.

According to GOST 24866-2014, the marking of a single-chamber double-glazed window is as follows - 4M1x16x4M1, where:

• 4 is the glass thickness in mm.
• M1 – brand of glass.
• 16 — width of the spacer frame.

Designation of additional properties:

• SPO - single-chamber.
• SPD - two-chamber.
• K or I - hard and soft low-emission coating.
• T0 and T1 - colored in the mass.
• Р1А, Р2А, Р3А, Р4А, Р5А - impact resistance and protection class.

If air was used as filling, there is no additional designation. Argon is denoted as Ar. Krypton - Kr.

Methods of decorating windows with impact-resistant double-glazed windows

There are several methods of decoration, thanks to which armored windows acquire an individual and unique look - laminating plastic or painting wooden and aluminum profiles, installing decorative layouts, using special tinted or stained glass film. They can be combined with each other or used separately.

What does an impact window consist of?

In production, we use not only frames made of plastic profiles (the most popular brands are Rehau, KBE, Novotex), but also aluminum with thermal inserts (warm aluminum) and wood of sufficient width (larch, oak, pine). An anti-impact glass unit is installed as a translucent filling. Reliable fittings are used for opening sashes.

Wood profile

Aluminum profile

In order to increase the protective properties of the window structure against the actions of intruders, it is recommended to use anti-burglary fittings in combination with a vandal-resistant double-glazed window.

Use of impact-resistant double-glazed windows

In impact-resistant double-glazed windows, our company uses laminated glass Stratobel and Stratophone produced by AGC Glass Russia. The company uses an exclusive PVB film with increased adhesion and rigidity, many times superior to analogues. This makes it possible to produce triplexes from thinner glasses, for example 3 + 3 mm, which ensures lower weight and cost of glazing.

Variety of glass decor

Most double-glazed windows are a regular plane without excessive decoration. But other options can also be used, for example, glass with sprockets - decorative metal profiles installed inside the double-glazed window. The profile width ranges from 8 to 26 mm. The color of the sprockets is silver, gold, bronze. They have a rather decorative appearance, but recently they have hardly been used.

In addition to spross, false linings are used - decorative elements of various configurations that are attached to the glass. They do not have any effect on the strength and tightness of the double-glazed window, but allow you to adapt any window to the features of the building’s exterior.

There can be many options for manufacturing double-glazed windows. If there is a choice, then professional builders should be involved - windows are not purchased every year, and they cost a lot. The comfort of housing and a healthy atmosphere in the house depend on their quality.

Double-glazed window according to functional purpose

You can order double-glazed windows based on their functional purpose. What types of packages are there and their characteristics, along with photos, will be discussed below.

Soundproof double glazing

This is a two- or three-chamber design that combines glass of different thicknesses (for example, 6 and 4 mm) and unequal width of spacer frames. This technique contributes to the occurrence of resonance during the passage of sound waves and their damping. Glass made using triplex technology is usually installed on the street side. Such windows are durable, have high thermal insulation properties and significantly reduce the penetration of noise from the street (37-39 dB).

Colored double glazed windows

An original solution for decorating the facades of modern buildings is colored double-glazed windows. They perform not only a decorative function, but also reliably protect the room from ultraviolet radiation, and also create an interesting atmosphere, shading furniture and walls. Adding tint to glass is done in two ways - by painting in the mass or by applying a film.

Which double-glazed window to choose for a plastic window depends on many factors:

1. What climate region do you live in? 2. For what purpose are you going to glaze the room; 3. What characteristics must be achieved when installing a plastic window; 4. Budget for window installation; 5. Type of house, features of the walls and window opening where the plastic window will be installed.

Triplex

The same laminated glass is used in the manufacture of triplex double-glazed windows. In this case, the emphasis is on strength and safety. The main function of such windows is maximum protection of the room from burglary, and those staying in it from cuts when glass breaks (the fragments do not crumble, but hang on the polymer film and have a rounded shape). They are used for glazing external storefronts, windows in high-rise buildings on the ground floor, country houses, children's institutions, banks, and so on.

Self-cleaning

These double-glazed windows allow housewives to save time and keep glass clean on the street side in hard-to-reach places. A special film is applied to the outer surface of such structures. Organic contaminants are destroyed by ultraviolet light and then completely washed away by rainwater. Water drops do not linger on the surface of the film, so the glass is always clean and transparent.

Energy saving

The glass on the windows is the coldest surface in the room; it is through it that most of the heat loss occurs. To retain heat indoors and keep the cold out, double-glazed windows are equipped with low-emissivity glass with i or k metal oxide coating. This layer reflects heat rays, returning them back into the room, retaining heat in winter, and protecting from overheating in summer. At the same time, spraying almost does not prevent the penetration of sunlight into the room.

The principle of operation of energy-saving double-glazed windows

Energy-saving double-glazed windows can significantly save heating costs, reducing heat loss from 40 to 20%, while their cost is slightly higher than conventional ones. In addition, the presence of low-emission glass in the glass unit almost eliminates fogging, since the inner surface is always warm. Spraying can reflect ultraviolet rays, which extends the life of the finish and furniture. Among the disadvantages of these products, it is worth noting a slight decrease in light transmittance, a more complex production process and loss of coating properties when the glass unit is depressurized.

Important! The heat efficiency of an energy-saving single-chamber double-glazed window is higher than that of a conventional double-chamber one.

Multifunctional double glazing

This is an improved version of an energy-saving double-glazed window, characterized by a two-layer coating of silver nanoparticles.
It costs a little more, but the difference in price is justified by the increase in all characteristics several times. Packages with multifunctional glass are also classified as solar-protective double-glazed windows. In such designs, one of the glasses is supplemented with a special film. It is usually located on the inner surface of the first glass, so it is not damaged and does not lose its tinting properties throughout its entire service life.

Advantages of multifunctional double-glazed windows :

1. Increasing the comfort of indoor conditions for people, animals and plants. 2. Protecting furniture from fading. 3. Savings on air conditioning due to reflection of sunlight. 4. The ability to use tempered glass with a light absorption rate of more than 25%.

Double-glazed windows with additional noise protection

Tinted solar glazed windows

Tinted double-glazed windows, which perform the same functions and have the same advantages, can also be classified as sun protection. We recommend installing them in windows located on the sunny side of the building. Tinting can be done either by applying a film or by:

1. By adding metal oxides to the mass at the glass manufacturing stage. 2. Magnetron sputtering of a film on glass under vacuum conditions. 3. Applying a layer of metals to a heated glass surface - the pyrolysis method.

"Smart"

“Smart” windows or smart windows are technologies of the future that have already become a reality. Such double-glazed windows operate on electricity, consume no more than one light bulb, are safe and multifunctional. Types of “smart” double-glazed windows:

• Electrically heated. These are double-glazed windows with low-emissivity coating and electrodes powered from the mains. This ensures the glass is heated and prevents condensation.
• Self-darkening. The level of darkness and transparency of such structures can be adjusted using the remote control.

Mirror double glazed windows

To protect the room from unwanted views from the street, which is especially important in offices and apartments of residential buildings, we recommend using mirrored double-glazed windows in the windows. They also reliably protect the interior space from sunlight, acting as curtains or blinds. They are often used to decorate facades, as the mirror finish looks original, modern and stylish. Thanks to the thinnest metallized coating (silver, titanium or chrome), mirrored windows block and reflect ultraviolet rays by 90%. The light transmission capacity is not reduced.

Energy-saving double-glazed windows with k-glass

The essence of these double-glazed windows is that a thin layer of metal oxides, mainly silver, is sprayed onto ordinary float glass. Waves of electromagnetic radiation are reflected from it.

In practice, this is reflected in an increase in heat reflectivity directed towards the higher temperature. This contributes to the absence of heat in the summer, in a room protected by such windows, and to the minimization of heat losses in winter. A spray thickness of 0.4-0.6 microns does not in any way reduce the transparency of the window, but significantly enhances it mechanically. K-glass is distinguished by its comparative simplicity of technology and does not add much to the cost of the entire structure. If there is a choice between k and i-glass, then you definitely need to choose the K-option. In addition to their lower cost, such double-glazed windows will not bring any surprises throughout their entire service life.

Double-glazed windows with i-glass

The glass manufacturing technology for such bags is much more complex than “K”. Sputtering is carried out in a vacuum and involves a kind of “sandwich” spraying, alternating oxide and metal layers (oxide-metal-oxide). In this case, the thickness of the metal layer (most often silver) is no more than 10-15 nm (10-9 m).

Even such a thin layer of metal reduces the thermal conductivity of the package by 90% without changing light transmittance. But spraying is quite vulnerable to external influences, so it is carried out exclusively on the inner surfaces of glass. At a comparative cost with K-packages, i-options allow you to save 20% more energy spent on heating. In addition, they are also 20 - 40% lighter, which makes it possible to install single-chamber, i-packages of any size in walls with not very high load-bearing capacity and in large-area structures - shop windows, facades, panoramas.
