Window installers will not tell you for sure (savings in installation and replacement of double-glazed windows)

Now everyone has plastic windows. Unlike wooden ones, they keep heat much better. They have the best soundproofing. When the developer tries to save money, installs single-chamber double-glazed windows. But they are suitable only for loggias, balconies, terraces, summer houses, southern houses.

Pros of fellow inmates: lightweight, economical, easy to install and handle, easy to transport. The wear of mechanisms (opening, closing) is less.

Significant cons: not complete insulation, poor heat retention, etc. The biggest disadvantage is that condensation may fall out, freeze.

Over time, the owners realize that it is cold at home, you can hear the noise from the street. They decide to change the windows to two-chamber ones.

How to save money and what are the installers silent about?

1. A single chamber consists of one air chamber and 2 glasses. Typically 4mm thick and 16mm air chamber. There may be other sizes. When a single-chamber double-glazed unit with ordinary glass, then problems may arise (freezing, condensation, noise from the street, etc.).

One problem can be solved. Energy-saving glass will help to increase heat saving. It will keep more warmth in winter and cooler in summer.

A single chamber with energy-saving glasses retains heat in the same way as a double chamber. However, noise protection will not provide high protection. If you only make glasses of different thicknesses and the distance a little more between them. The noise will be less audible due to the increased air gap and the difference in glass thickness.

You can reduce the noise level by ordering a single-chamber double-glazed window filled with heavy gas (argon). Manufacturers assure that this option can be called energy-saving.

This is true, but the thermal characteristics increase by a little - only 5%. It is worth filling the glass unit chamber with gas - 200-300 rubles.

2. About itwindow installers won't tell you! A single-chamber double-glazed window can be changed to a 2-chamber one without removing the entire frame. No need to break out and install new 2-chamber windows.

The glazing beads are simply removed (extended strip made of PVC or fiberglass). A new glass unit and new glazing beads are ordered.

Then the single-chamber double-glazed window is carefully removed. A single-chamber window is replaced by a 2-chamber one. It will be much cheaper.
