As you know, it is through window openings in rooms of any type that most of the heat is lost. Previously, to save it, windows were made small. However, with the advent of modern technologies and materials, it became possible to build even glass walls. Why is heat retained?
The thing is in modern double-glazed windows, which are installed in window structures.
What is a double-glazed window?
Very diverse modern double-glazed windows. The technical characteristics of these special structures directly depend on the type of glass, sealant and distance frame used in the manufacturing process. Typically, the spacer frame is made from a durable polymer. Double-glazed windows are divided into classes depending on the number of air chambers:
- single chamber;
- two-chamber;
- three-chamber;
- five-chamber.
The space between the glasses is filled with special gas. Glasses themselves can also be different. For example, energy-saving, with a high level of strength, etc.
A huge number of indisputable advantages are modern double-glazed windows. Technical characteristics of such structures are very high. Due to this, window constructions are able to provide precious heat and desired coolness even under critical temperature conditions.
For different climatic zones, experts recommend using different types of double-glazed windows. Each species is distinguished by individual technical characteristics and features. A correctly selected and high-quality double-glazed window is the maximum comfort and coziness in any building, structure and construction.
Technical characteristics of modern double-glazed windows
Modern double-glazed windows can be divided by such characteristics as:
- number of air chambers;
- thermal insulation level;
- sound insulation level;
- level of protection against direct sunlight;
- security level;
- cost;
- appearance;
- the size;
- the form;
- availability of certificates of compliance with existing international requirements, standards and norms;
- other non-standard parameters (for example, the ability to change the color of the glass).
Today, by contacting one of the large companies that specialize in the production of double-glazed windows and window structures, you can order double-glazed windows, the technical characteristics of which, as well as the shape and size, may be the most optimal for your home or office.
Each type of double-glazed window has individual features, therefore, when choosing, it is necessary to consider each class separately.
Single chamber double-glazed windows
Modern single-chamber double-glazed windows have the lowest characteristics. However, there is also an undeniable advantage. In this case we are talking about low weight.
Such designs may have different thicknesses. Namely:
Depending on the thickness of the structure, its weight will change. Respectively:
- 16 mm - 21.7 kg (sq. M);
- 18 mm - 22.13 kg (sq. M);
- 20 mm - 22.56 kg (sq. M);
- 24 mm - 23.45 K. (sq. M).
The thicker the glass unit, the higher the noise isolation parameters and the level of heat transfer resistance. But such parameters as the transmission of solar energy and light remain unchanged (0.78 and 0.80).
For a temperate climate, it is quite possible to use a single-chamber double-glazed window. The technical characteristics of this design, of course, should be quite high. This is made possible using double-glazed windows with a thickness of 24 mm.
Double-glazed double-glazed window: specifications
Double-glazed windows have three windows, separated by air space and a special profile. Such designs have higher soundproof and heat-insulating parameters than those with a single air chamber.
Such double-glazed windows are much more expensive. However, their higher price is fully justified. A simple double-glazed window can be compared with a single-chamber double-glazed window, but only subject to the availability of a special energy-saving glass.
Thickness of two-chamber structures and corresponding weight:
- 24 mm - 32.5 kg (sq. M);
- 28 mm - 33.4 kg (sq. M);
- 32 mm - 34.3 kg (sq. M);
- 36 mm - 35.2 kg (sq. M);
- 44 mm - 36.9 kg (sq. M).
The thicker the glass structure, the lower the level of free access to sunlight. In double-chamber double-glazed windows, this figure reaches 0.72. It is worth saying that the lowered rate is not critical. Such parameters are quite enough for a comfortable life.
Double-glazed windows of three-chamber type
If you live in a cold climate zone, where harsh winters are the norm, then in this case, experts recommend paying attention to a three-chamber double-glazed window, consisting of 4 glasses and 3 air chambers.
Three-chamber double-glazed window technical specifications is really high level. With such windows you will never freeze! But in this case, it is necessary to take into account the load that will fall on the foundation and walls of the building.
With the above three-chamber structures, no type of double-glazed windows can be compared in terms of sound insulation. Therefore, if you value peace and quiet, then the choice is obvious.
Modern five-chamber double-glazed windows
A modern five-chamber double-glazed window, the technical characteristics of which are at the highest level, can only be compared with three-chamber glass structures. Such double-glazed windows are rarely installed in our country, since they are intended exclusively for harsh climates. Although similar windows are found in some country cottages and houses, they can significantly save heat and maintain optimal temperature inside buildings. It is five-chamber glass structures that are used for glazing large windows, but this does not apply to high-rise buildings (due to the large weight).
Energy-saving double-glazed windows: technical specifications
New technologies and innovative developments have allowed to obtain a new generation of glass. Many consumers prefer to install special double-glazed windows in their country houses and city apartments - energy-saving. The technical characteristics of these structures give them unique properties that allow them to retain heat in the room, despite weather conditions and other atmospheric phenomena.
Energy-saving glass is coated with a special coating of silver oxide. It is this protective layer that serves as the filter that freely passes short waves of solar radiation (heating furniture) into the room and reflects infrared long-wave radiation (heat) back into the room.
Savings with such glasses are about 40%, which, in turn, is quite high, given the existing high tariffs.
Universal window constructions
The universal design today is a double-glazed window of 24 mm. The characteristics of this class of glasses correspond to all the desired ratio: "reasonable cost - high quality." The main advantages of universal glass structures 24 mm:
- relatively light weight;
- excellent level of heat and sound insulation;
- an opportunity to order window designs with a double-glazed window of 24 mm of any size and form;
- excellent appearance;
- reasonable cost.
A modern 24 mm double-glazed window, the characteristics of which fully comply with the conditions of most cities of our country, will be an excellent choice. There is no point in overpaying and installing expensive windows if you can get the best and really reliable option at a more than affordable price!
We see such windows everywhere: in city apartments, country houses, country cottages, offices, shops, child care facilities, etc. Their incredibly high popularity and demand indicate that they are perfectly suited for creating the most optimal living conditions.
Caring for windows and double-glazed windows
In order to prolong the life of the windows, it is necessary to follow all the rules for care and maintenance. In reality, modern double-glazed windows and window structures do not require complicated special care. It is quite enough to clean the window structures from dust and dirt two or three times a year. To do this, use warm water, simple soap and lint-free napkins. It is advisable to wash the glass with special means that do not leave streaks and make the windows shine in the literal sense of the word.
It is important to clean the seals in a timely manner. In case of damage, the heat will go outside, and then it will not matter what kind of double-glazed windows are installed in the window profile.
Rules for the care of window structures:
- To wash glass, window profiles, gaskets, it is necessary to use warm soapy water and lint-free wipes. It is also allowed to use special detergents that do not contain abrasive substances (such substances can damage surfaces).
- It is necessary to periodically check the fittings and tighten parts and elements that have become loose over time. Fittings should be lubricated 2 times a year with oil. You can use a brush to do this.
The key to a comfortable and cozy life is good windows and reliable double-glazed windows! Technical characteristics when choosing such structures must be studied without fail! Indeed, only correctly selected double-glazed windows will serve faithfully for many years and will help create the most comfortable conditions for you and your loved ones!
