Wooden heat-saving windows. Heat-saving glass

Proper glazing is one of the important factors in saving energy in a room, since a lot of heat can be lost through windows, and a significant proportion of the losses are due to infrared radiation. It is possible to reduce convective heat loss through the window by increasing the number of glasses and chambers in the package and installing a warm separating frame, while infrared radiation can be kept indoors due to the heat-reflecting glass coating.

If sufficient thermal insulation is not provided in the edge zones of double-glazed windows, the window freezes, becomes covered with frost, and the room leaves through it. warm air and cold seeps in. When using traditional aluminum dividing frames in the design of double-glazed windows, this problem is observed quite often.

Stainless steel frames improve the thermal properties of the double-glazed window. But the best heat-insulating properties are possessed by the so-called warm frames of the warm edge system, for the manufacture of which fiberglass, plastic, silicone and similar polymeric materials are used.

Read about other types of distance frames.

The material of the warm frames is durable and does not lose performance characteristics under the influence of sunlight, is not afraid of moisture. The thermal conductivity of warm frames is much lower than that of aluminum, therefore, thermal insulation characteristics above. In practice, double-glazed windows with a warm frame ( warm edge) have the following advantages over windows with an aluminum separating frame:

• v winter time the temperature of the edge zones of the window increases by 5-6%;
• the formation of condensate, mold is prevented, in winter - frost;
• there are no places in the design that are vulnerable to the penetration of cold from the outside;
• heat loss through the window is reduced, the coefficient of heat transfer to the room reaches 70%.

Heat reflective glass coating

Even a single-chamber package of two glasses retains heat well in the room if it is applied to the glass. It is almost transparent, permeable to the rays of the visible spectrum (the light transmission of an energy-saving window with a heat-reflecting coating is only 4-5% lower than usual).

The essence of a heat-reflecting (low-emission) coating in an electoral bandwidth. It passes solar energy (short-wave) well into the room, and long-wave energy released by heating devices and obtained as a result of solar conversion, it retains in the room. Heat losses are reduced, cold zones in the window area disappear, the draft effect is eliminated, and the likelihood of condensation is reduced, since the glass warms up well.

Back in the USSR, a technology for applying a three-layer coating was developed: the reflective layer is located between the buffer and protective ones. Silver, silver and copper are used for reflective, and aluminum, tin, titanium are used for buffer and protective. The coating according to this technology is applied to the cleaned glass by deposition in a vacuum, deposition can be arc or magnetron. Today, heat-reflecting coatings are divided into "soft" and "hard", or I-glass and K-glass.

• The soft coating technology is simpler, the vacuum cathode sputtering method is used, the coating is two-layer, the silver layer directly reflects infrared rays, and the titanium oxide layer is protective.
• A hard coating is applied by pyrolysis directly in the process of glass production, at the moment when it is hot and not yet cooled down. The peculiarity of K-glass is that metal particles penetrate into the crystal structure of the glass, the metallized heat-reflecting film is covered with a thin protective layer glass.

The adhesion and damage resistance of a hard coating is higher, but the actual heat-reflecting characteristics are better for a soft coating, and it lays down more evenly. In addition, the technology of its application is preferable in terms of environmental impact. Rigid heat-reflecting coating is losing popularity nowadays, since the process of applying it is very laborious, which affects the cost of such glasses and double-glazed windows with them. I-glass is more affordable, but less durable, the coating has a low chemical resistance.

The properties of the heat-saving film allow energy-saving windows to winter period keep the heat in the room and reduce the cost of heating it. In summer, they prevent overheating of the room, creating a comfortable and favorable microclimate in it.

Double-glazed windows with a heat-reflecting coating are more expensive than conventional ones, but more economical due to the ability to reduce the number of cameras when choosing a double-glazed window and saving on heating after installation. This technology makes it possible to get by with a smaller number of glasses - a single-chamber double-glazed window with heat-reflecting glass is superior in terms of heat-insulating characteristics to a two-chamber one without sputtering. This perfect solution for conditions that do not allow the use of massive double-glazed windows and solve the problem of heat saving by increasing the thickness of the glasses and the number of chambers.

There is another technology for the manufacture of energy-saving windows, which has not yet received widespread due to the high cost, but characterized by exceptional energy efficiency. This is the so-called electrically heated double-glazed window made of tempered K-glass with conductive tracks, it is connected to the power supply and used as a heating element. Such double-glazed windows can be installed in unheated rooms.

Sliding warm glazing

On balconies and loggias, as well as on verandas, sliding glazing is often used, which allows the most efficient use of the available space. At the same time, the frames do not swing open, but move relative to each other. Such glazing can be cold (aluminum) and warm (using a plastic profile). If the glazed room is planned to be heated and used as a residential area, you cannot do without it, although it is more expensive.

Sliding systems based aluminum profile can also have a thermal insert, such systems can be used for warm glazing and are not inferior in energy efficiency to plastic double-glazed windows.

One of best solutions for warm sliding glazing - PVC system SLIDORS (Slidors). These systems are made of PVC profiles with galvanized fittings inside; in double-glazed windows, a double seal with a special insert is used. Double-glazed windows combine high strength with excellent heat and sound insulation characteristics, they are waterproof, thanks to the high rail they can be used in any weather. By price sliding systems based on a PVC profile is more accessible than hinged ones.

For warm sliding glazing, the KBE PremiLine system can be used, provided that energy-saving double-glazed windows are installed. The LG Hausys system with 18 mm double-glazed windows is also used for warm sliding glazing.

Panoramic warm glazing

The good thing is that it lets as much light into the room as possible. On the other hand, an increase in the glazing area can lead to an increase in heat loss in winter. Therefore, it is important to use for warm panoramic glazing not single glasses, but double-glazed windows, and with the best heat-insulating characteristics. For these purposes, it is worth choosing double-glazed windows with chambers filled with argon, low-emission glass coating and a warm separating frame.

For warm panoramic glazing, it is preferable not to massive PVC packages, but to lighter windows based on an aluminum profile with a plastic thermal insert. SunFlex structures (Germany) are ideal, this is a folding system that allows glazing openings of various configurations up to 3.5 m high, and performing non-threshold glazing. The design is characterized by low thermal conductivity and high soundproofing properties, each leaf has a double sealing contour. The system can be aluminum or wood-aluminum, has an aesthetic appeal.

The heat-saving characteristics of a window depend on a number of parameters - the thickness and number of glasses, the thickness of the chambers and their filling, the material of the dividing frame, the presence of a heat-reflecting coating and the technology of its application. The heat-saving properties of the window are enhanced by filling the chambers with argon, the use of a polymer dividing frame, and low-emission sputtering on glass. Windows that combine several heat-saving parameters are the most effective.

For the manufacture of energy-efficient windows at ISOLUX, manufacturers can order ClimaGuard ® heat-saving double-glazed windows 4 mm thick with a silver-based protective layer, as well as packages with I-glass 4 and 6 mm. Both those and others are filled with argon.

Advantages of heat-saving double-glazed windows

Durability and reliabilityWindow systems with heat-shielding double-glazed windows are lighter and load the fittings less, prolonging its service life. Low-emission coating is maintained throughout the entire period of operation of the system.

Effective thermal protection in winterThe design insulates heat much better than the standard, although it weighs less. A package with one chamber of two energy-efficient glasses is 1.5 times lighter than a typical one and retains 25% more heat in the room.

Comfortable microclimate in summerV summer heat bags reflect heat waves to the outside and keep the room pleasantly cool.

The heat in the room is provided by two sources. First - solar radiation, entering the windows from the outside - ultraviolet, visible light and short infrared waves; the second is heated objects and heaters in the room, from which long IR waves emanate. Help prevent heat loss I-glass with low-e coating reflecting infrared radiation into the room. The ion-coated glass is mounted first so that the coating is located inside the glass unit. Silver ions on the surface of the heat-efficient package create a mirror effect. In contact with heat waves from heating appliances, they direct the radiation back. As a result, the heating intensity can be reduced by up to 50%.

Energy packagesClimaGuard®Solar multifunctional. They solve two problems: in winter they keep heat in the room and in summer they protect the room from the sun. One layer of their coating reflects heat waves from heated surfaces into the room, the other one retains up to 60% solar energy. Silver plating does not affect the transparency and optical properties of glass, helps to save on heat supply, and prevents windows from fogging.

So summer is over, it's time for warmth, and with it autumn begins and preparations for heating season. Batteries will turn on very soon, as well as electric fireplaces and gas heaters that consume hot water, gas and electricity in large quantities. In connection with this situation, the question arises related to reducing the cost of space heating, and one of the most practical and cheap solutions is to replace ordinary windows with heat-saving ones. Saving energy and finances when using these windows is obvious: when using them, heat exchange with external environment reduced by 70%, which leads to a similar reduction in heat loss, and, of course, your money!

STIS double-glazed windows - Laureate of the "SAVE ENERGY" Award

What are heat-saving windows?

What are heat-saving windows? This regular windows with special glasses as part of double-glazed windows, covered with a very thin layer of metal, which practically does not allow heat to pass through itself - that is, it will be warm in the apartment in winter and cool in summer, while ordinary glass practically does not delay it. Also, a serious advantage of this type of windows is that it prevents furniture, wallpaper and carpets from fading, that is, over time they will not lose their color and brightness due to the sun! These windows also differ in types of coating: hard coating, used in single glazing without double-glazed windows (for example, when glazing balconies, loggias, etc.), and soft coating, which is universal in nature, because it has higher thermal insulation parameters and used only as part of a double-glazed window.

Glass-composite profile + double-glazed window: the ideal formula for a warm window

Also, one of the most significant advantages of heat-saving windows is that they are much lighter and stronger than their glass counterparts, which not only makes them easier to use, but also significantly increases durability due to the use of alloys and composites in them.

Thus, the advantages of energy-saving double-glazed windows are obvious, and if you want to get the best combination of price and quality, you can safely order them and calmly meet the heating season.

Please note that 80-90% of the Russian market are "B" and "C" classes and only 10-20% of "A" class profiles. At the same time, our range VEKA profiles Class "A" ONLY.

As a matter of principle, we DO NOT use profile systems of classes "B" and "C" (with a front wall width of less than 3.0 mm).

ONLY frost-resistant profiles

According to GOST 30673-99 "PVC profiles for window and door blocks" in terms of resistance to climatic influences, ALL of our profiles are "frost-resistant" - for areas with AVERAGE monthly air temperature in January BELOW minus 20 ° C.

GOST standards for different classes:

• normal version "N": average temperature in January - minus 20°C and above
• frost-resistant version "M": the average temperature in January is lower than minus 20°С

In our assortment ONLY frost-resistant profile systems, marked with the letter "M".

Heat transfer resistance (thermal heat resistance) is the main coefficient of thermal insulation. It is determined by the ratio of the temperature difference outside and inside the room to the heat flow passing through the window. The higher this number, the better the thermal insulation efficiency.

Evolutionary double-glazed windows SmartGlass 2.0

Our multifunctional double-glazed windows work for you both in winter and in summer. In winter, sputtering of silver particles saves up to 90% of the thermal energy of heating devices, and in summer a double-glazed window reflects 25% more solar heat than conventional ones. plastic windows.

• 42% more HEAT in winter (energy saving properties)
• 25% less HEAT in summer (sun protection properties)

All our double-glazed windows contain special energy-efficient glasses. We DO NOT use ordinary glasses even in the most basic configurations.

AirDrive I, II and III climate control systems

Optimal ventilation mechanisms are built into the windows - the sashes open slightly by 1-5 mm, depending on the selected mode. These are NOT external devices (combs or valves), but BUILT-IN furniture ventilation.

Three options:

• AirDrive I: night ventilation (1 mode)
• AirDrive II: discrete multi-stage ventilation (3 modes)
• AirDrive III: discrete multi-stage ventilation (5 modes)

We try not to put combs because of them appearance(only at your request). In principle, we do not use valves due to the fact that they violate the integrity of the window, reduce its tightness and strength (since the profile and its reinforcement are drilled through).

Comfort and warmth in the house depends on the quality of window structures. Many people want to buy windows in Moscow that have high thermal protection rates and let sunlight into the room well.
