Double-glazed windows have appeared on our market for a long time. Buyers are becoming more literate every year. Now even metal-plastic windows with energy-saving glasses are not something special and are increasingly used for glazing apartments.
Today energy-saving double-glazed windows are produced on the basis of
low -
emission glasses. There are two options for the technological manufacture of glass. In the first case, the coating is applied during the manufacture of glass at a very high temperature. In this embodiment, the coating molecules penetrate deep into the glass and act at the level of the crystal lattice. This method allows you to get a hard, durable coating, called K-glass.
But now they often use a different type of glass. The coating containing silver occurs in a vacuum chamber. The cost of such glass is lower, but its storage conditions are slightly tightened. This is I-glass, which is also called "soft coating". Now energy-saving double-glazed windows are most often made with I-glass.
Assembled single-chamber double-glazed window represents the following structure. From the side of the street there is an ordinary 4 mm glass. For double-glazed windows, glass with a mark of at least M1 should be used so that the presence of inclusions is minimal. If necessary, the glass thickness can be increased to 5 or 6 mm. It depends on the size of the package and the requirements for protection against external noise, which energy-efficient glass units must comply with.
If you use a single-chamber double-glazed window, then the second glass should be soft coated. In labels that are glued to a double-glazed window, I-glass denotes TopN. When glazing with two-chamber double-glazed windows, the first and second glasses are put ordinary, and the coated glass is inside. In order for energy-saving double-glazed windows with a soft coating to last longer, argon is not pumped into the package, but air. This is usually done in special cells.
It is enough to install a double-glazed window with two glasses, one of which with an energy-saving coating, so that you immediately feel the difference. If your batteries are turned on and there are such double-glazed windows, then the apartment will become warmer. In those places where severe frosts occur in winter, it is better to immediately install a two-chamber double-glazed window, strengthening it with an energy-saving coating.
So, you have come to the decision to install energy-saving double-glazed windows. The reviews expressed in various forums will help you to correctly approach the final choice. Especially if these are the statements of people living with you in the same city. There you can find wishes not only regarding double-glazed windows, but also companies that offer their services in this area.
But, so that the windows do not disappoint you in the future, try to take into account not only temperature indicators. After all, an energy-saving double-glazed window does not pass heat to the street, but at the same time it passes sunlight into the apartment. This is very good in the winter season, and in the summer can be a minus. To protect your furniture from burnout and create more comfortable conditions for yourself, it is worth considering this problem. In this case, it is enough to stick sun-protection film on the street glass.
