What are double-glazed windows and what are their uses?

A double-glazed window is a window that has two layers of glass, they have many uses, specifications and advantages. For several years, with the help of advanced science and technology, a new type of conventional window to double-glazed window has entered the market, which has brought unparalleled comfort and peace to the residents of apartments in crowded neighborhoods. In fact, double-glazed windows are a type of sound and thermal insulation that significantly prevent energy waste and sound transmission in the building. Windows are one of the important indicators of a building's energy efficiency, and extensive research has been carried out since the last decades. This paper examines the performance of various window technologies, covering the physical and optical properties of traditional windows and advanced window technologies. In window technologies, one of the most important parameters is its thermal transmittance or U-value. In this article, we discuss the relationship between the physical and optical parameters of different types of windows and its U value. In addition, this article also provides the interested readers with a wide range of information, including research gaps in window technologies. Among the main results, we found that, although several advances have been made in this field in the last decade, more research is needed to develop window technologies that not only have high insulating properties.

A double-glazed window refers to a window that has two panes of glass. The main component of the window is the double-glazed sealed unit, also known as the insulating glass unit (IGU), which is housed in a frame of UPVC, aluminum or thermal break. The IGU consists of two sheets of glass separated by an insulating frame to create an air gap filled with an insulating gas. A bit like a glass bread sandwich filled with air. The main benefit of double glazing is thermal insulation – to keep heat in a room while preventing cold air from entering the room to save energy. Double-glazed windows make such a difference to energy efficiency that building regulations were set in 2002, meaning all replacement windows must have a minimum double-glazed rating of C – unless the property is a listed building or in a conservation area. Compared to the old doors and windows, which are often produced from iron profiles, and in addition to the heavy load that they impose on the building, and over time, they get rusted under the influence of weather conditions, the double-glazed window, with UPVC profiles, now have entered the market They have high resistance to weather changes and are of high quality. Therefore, these windows are currently used in most constructions as a suitable insulation to prevent sound from entering inside and wasted energy.

It may be hard to remember a time before double-glazed windows, as most homes today have upgraded their windows to be more energy efficient. But, once upon a time, we all lived in houses with cold, shivering windows. There are various claims as to who first experimented with double-glazed windows, but it is generally thought that the Scots were the first to do so in the Victorian era. Adding a second pane of glass to your existing windows to ward off the harsh Scottish elements. Although, it is noted that the Romans also had their own heat preservation system. Commercially, the double-pane window was "invented" in the United States in 1930 by CD Haven and later registered as "Thermopane" by an Ohio glass company. After this, in the 1950s, double-glazed windows began to filter into American homes. In 2003, Tehran, Tekindos started its life by selling a version of aluminum secondary glasses. In 2009, when we developed our first aluminum double-glazed window product. In 1392, our uPVC double glazed window was made and it quickly became the window of choice for people.

These types of windows are produced from UPVC frame glasses which are also double-glazed. In fact, UPVC is considered an alternative to non-metallic and metallic alloys that are used in the preparation of doors and windows. One of the important features of the doors and windows that are made with upvc can be mentioned very high resistance to collective changes, style and lack of employability. The main structure of UPVC windows is based on the double-glazed glass used in it. In this type of double-glazed window, two or more layers of glass are separated from each other with a spacer tape that is glued all over, and the space between the multi-glazed glasses is filled with argon, air or SF6 gas. Spacers are mostly made of aluminum, which are filled with silica gel, which is actually a type of moisture absorber, and leads to moisture not remaining between the glasses.

Double-glazed windows have many advantages, some of the most important of which are: Breaking two layers of glass requires a lot of energy and pressure. Therefore, types of double-glazed windows have very high security. The space between the glasses, which is filled with argon gas, actually forms a thermal insulation and prevents heat from escaping from the inside to the outside of the building. Double-glazed windows will prevent heat from escaping in the cold season and prevent it from entering the building in the hot season. Installing double-glazed glass prevents energy wastage and related costs. In addition to being considered a type of thermal insulation, this window also prevents noise pollution from entering the building. In fact, double-glazed windows will eliminate sound and create a peaceful environment for the residents of the building. The double-glazed window is very easy to clean and does not need to be painted. Dust will not penetrate in double-glazed windows in any way and they have a very high resistance to water penetration. Double-glazed UPVC windows are highly resistant to weather changes and will not change shape in any way. The use of UPVC windows reduces the costs of heating and cooling the building, and as a result, they are economical. These products are completely sealed, which prevents water from penetrating into them during heavy rains. Sealing the windows will prevent dust from entering the building. Windows are very resistant to ultraviolet radiation and will prevent its transfer to the interior of the building and also remove the harmful effects of this radiation. The long life and stability of this product has made it possible to reuse double-glazed windows after destruction and renovation, which is one of the unique features of double-glazed windows. Another advantage of double-glazed windows is that they are non-flammable. In addition, they are highly resistant to corrosive substances such as acids, bases, and other chemicals, as well as decay. Double-glazed windows are economical.

Double-glazed windows consist of various components, the most important components of which are the following: Profile Glass fittings Reinforcement or galvanized (for upvc double-glazed windows) connector Holder or Zamak Abandi tires
