Such an innovation as warm glass has appeared on the domestic market quite recently, but has already managed to win the sympathy of many consumers. Nevertheless, an impressive number of our citizens have not even heard of such a heating system. So what are the double-glazed windows with heating, what distinguishes them from ordinary windows, what are their advantages and do they have disadvantages? We will consider all these issues in this article.
What are heated double-glazed windows and how they work
The principle of operation of such glasses is based on the combination of two main tasks: to provide the room with a lot of sunlight and heat it.
Many will decide that warm glasses are the same automobile glasses inside which you can see a metal grid, but this is far from the case. Externally, double-glazed windows with heating are no different from ordinary plastic windows. At first glance, it is difficult to guess that the wiring is located inside the profile, and even transparent glass (of standard thickness) is coated with an even and very thin layer of metals that plays the role of a heater.
The structure of the heating element includes a protective and insulating layer, so that the thermal radiation is directed only one side from the window. Therefore, you should not worry at all that a significant part of the heat will go outside.
This system very quickly heats the glass to the desired temperature and maintains it for a long time.
Technology for the production of electric glasses
The process of manufacturing double-glazed windows with electric heating practically does not differ from the procedure for manufacturing ordinary window packages, which is as follows:
1. On the cutting tables, using a diamond glass cutter, cut the glass of the desired size.
2. The cut sheets will be driven through a special machine that rounds off all the sharp edges of the product. This procedure makes the glass more durable and prevents it from crumbling.
3. Prepared products are sent to the oven.
4. The tempered glass goes through the process of cleaning and washing.
5. A special desiccant is poured into the cavity of the distance frame, which is laid between the glasses.
6. A contour is glued to the finished glass, and a second glass is laid on top. The resulting product is sealed and pressure tested.
7. After crimping, a second layer of sealant is applied.
The difference in the production of ordinary and warm glasses is only in the installation of electrical conductors, a protective film and a sensor that controls the temperature to which heated double-glazed windows are heated.
The production of these products is based on the use of tempered and safe glasses, the strength of which is significantly higher compared to conventional counterparts.
What are the features of warm glasses
Heated double-glazed windows (the technology of which is based on connecting to electricity) are absolutely safe, since contact buses that conduct current are located inside the system, and access to them is possible only in case of product destruction. We also all know that glass acts as an excellent insulator, so it is simply impossible to get an electric shock.
The presence of a protective film prevents the formation of a large number of fragments (in case of damage to the glass). A failed window element can be removed and replaced without fear.
These systems can be installed in absolutely any window constructions, whether it is a plastic, aluminum or wooden profile.
Models with warm glasses can be in the form of a rectangle, triangle, circle, trapezoid and other non-standard shapes. They can be installed in both deaf and openable structures.
Key Specifications
Warm double-glazed windows with heating have the following characteristics:
• the maximum window size with warm glass is 2400 x 4800 mm;
• minimum size packages have dimensions of 300 x 400 mm;
• single-chamber bag thickness is 17 mm;
• the thickness of a two-chamber double-glazed window reaches 30 mm;
• maximum system heating temperature +55 degrees;
• soundproofing ability of the window is at the level of 31 dB;
• power consumption (depending on window size and set heating temperature) varies from 50 to 800 W m²;
Benefits
Let's look at the advantages of double-glazed windows with heating. Customer reviews talk about the following positive qualities of this system:
1. They do not need expensive maintenance.
2. Condensation never forms on warm glass.
3. Contribute to reducing dust in the room.
4. Do not occupy additional space (unlike heating radiators and heaters).
5. Due to the presence of protective layers, the glasses have a very high strength, therefore they are quite resistant to mechanical damage.
6. Consume some electricity. With small frosts on the street can act as the main heating.
7. They are an excellent heat insulator. In cold weather, the house does not get cold, and in summer the room remains cool.
8. Warm windows can be connected to the smart home control system and alarms. In the latest version, double-glazed windows with heating will serve as an additional security sensor.
9. The glass is heated evenly over its entire area. This property eliminates the possibility of thermal patterns.
Scope of warm glasses
Today, double-glazed windows with heating have found particular popularity in roof glazing. This is due to the fact that their high temperature does not allow much snow to accumulate on the roof.
Also with the help of warm glasses can be equipped with:
• winter gardens;
• balconies and loggias;
• facades of apartment buildings;
• pools;
• Sport halls;
• greenhouses;
• large windows;
• interior partitions;
• stained glass;
• anti-aircraft flashlights, etc.
What is the cost of electric double-glazed windows
Touching on the price issue, it should be noted that heated glass windows are far from cheap pleasure, and this is perhaps their only drawback.
So, tempered glass with a thickness of only 4 mm will cost the consumer from 8400 rubles per square meter (subject to the use of an aluminum profile).
Glass, whose thickness is 6 mm, will already cost about 9800 rubles for the same size.
A single-chamber double-glazed unit with a total thickness of 24 mm will already cost from 11 thousand, while the material used for the manufacture of the profile will be plastic or wood.
The price tag for two-chamber warm double-glazed windows (whose thickness is 32 mm) starts at 12 thousand per square meter. Natural wood or PVC can also be used here.
Please note that the final cost may vary depending on the reliability of the manufacturer and the quality of the components used (such as a sensor and a temperature controller).
When choosing these products, do not give preference to unfamiliar and cheap companies that have manufactured double-glazed windows with heating. Manufacturers who are confident in the quality of their products give at least two years of warranty and more than 10 years of free after-sales service. In other cases, there is a big risk that the glass heating will quickly fail.
Conclusion
Summing up, I want to note that there are a lot of positive aspects of electric double-glazed windows. Collected together, they allow you to build entire rooms from this material, which are distinguished by airiness and visual infinity.
Warm glass has greatly expanded the capabilities of architects and designers, because with its help you can implement even the most daring ideas. Projects with large windows and
transparent roofs, which previously could not be implemented (given the harsh Russian climate), are now available to everyone.
We hope that the information presented in our article gave answers to all your questions related to warm double-glazed windows.
