There is a layer of dry gas (e.g. argon, nitrogen) between the two panes of glass that acts as insulation, preventing heat flow in either direction between the glass panes. One thing very important is that the gas fill between the panes must be dry, or condensation will form between the panes in winter!
In industrial environmental testing temperature chambers this is taken to an extreme, with in some cases about a dozen panes of glass separated by either dry gas or vacuum to insulate the very high or very low internal temperature of the chamber from room temperature.
Air is usually trapped between double pane windows to act as an insulator. The layer of air acts as a barrier to reduce heat transfer, improving the window's energy efficiency. Additionally, it helps to reduce condensation and noise transmission.
to the people who want to know the answer to How can you clean a double glass window. To clean a double glass window you need two people. You need to get cleaning spray for the double glass window. You also need a cloth. Then after getting them, you can clean your double glass window.
The reason for using a double glazed window is that the two window panes trap a layer of air between them, which provides much better thermal insulation than a single pane of glass would provide, so a lot less heat is lost through the closed window during cold times of the year. During warmer times of the year, if you have air conditioning, then less heat enters the house through the closed windows.
The advantage of double glazed window units is how well they are able to insulate a house. A double glazed window unit can actually save a household hundred of dollars every year in electricity.
Basically you can't - you have to replace the whole double-glazing unit. Double glazing has an inert gas injected between the panes during manufacture - which aids the sound insulation properties of the unit. Once one pain is cracked - that gas escapes and is replaced by air - which is not a good sound insulator.

The air in a double pane window is insulation from cold weather.
If you mean in computers, then a double open window is either two programs running or a internet open with another tab open aswell. ;)

Vinyl windows are very important to a home.A replacement window will conserve energy in all seasons. The vinyl is the plastic material around the glass that fits where your old wooden window pane set. You can purchase vinyl window replacements online,at home stores,or window dealers in the yellow pages.
A cabinet window is a shop window with curved sides, commonly seen during the nineteenth century.
The double pane window should be more efficient in keeping heat out. However, there is also more heat transfer from the frames if they are metal rather than vinyl. And the surface area of the double pane window is greater so it takes more time for the energy to be absorbed than the single pane window....I think:( My friend told me this information
