New Windows frequently have two or even three panes with space between them for insulation. They keep heat or air conditioning from leaking outside.

It's called double (or triple) glazing: triple being used in more extreme, especially very cold, climates.
Homes with two panes of glass in windows have double-glazed windows, which offer better insulation and noise reduction compared to single-pane windows. The space between the panes is typically filled with insulating gas to improve energy efficiency.

Double glazing is the glazing process in which a window is formed by two panes of glass with a space between the panes. The space between the glass is usually several millimeters thick
Yes, a double glazed window - two panes of glass with an airspace between them - will provide considerably higher insulating value than a single pane of glass. For even greater insulating value, the space between the panes can be filled with argon gas instead of air. Argon-filled windows, often called Low E windows will generally be more costly than regular air-filled windows. Ray

I assume you are referring to double-pane windows, which are constructed by using two panes of glass separated by a space. The frame in which the panes are held is sealed (sometimes, an innert gas is used to fill the space between the panes as a way of limiting ultraviolet radiation penetration), and is airtight. If that seal is broken, air from outside the panes can enter the space between the panes of glass. This will result in the gradual introduction of moisture into the space. The amount of moisture will not be substantial at first, because there won't be much exchange of air from the space between glass panes and the outside unless there is a fairly substantial breach of the seal. That would usually require some substantial force, and would likely break the glass, anyway. Because there is virtually no regular circulation of air between panes (even if the seal is eroded in some spot), any moisture that gets between the glass will stay there. Furthermore, since there is (now) a breach in the seal, heat will cause the air between the panes to expand and cooling will cause the air to contract. This will keep a regular supply of moisture entering the space between the panes. The fog results from the moisture condensing on the glass in the space between the panes. When a seal is breached, you will first notice just a small bit of moisture , and that will usually be localized to the area of the breach, spreading out over time. This process takes years before you have a large portion of the window fogged. At its worse, the real issue is not the vapor itself (although it will eventually block your view in or out of the window), but the introduction of mold spores or other microorganisms which will grow in the nice, moist environment. (A neighbor of mine let this process get so bad that the entire window was coated with mold.) There is no way to repair this problem - the seal, once broken, has already introduced moisture which cannot be effectively removed. the pane must be replaced.
Double pane glass are passive items, they don't "do", or regulate anything. But doble paned windows are better insulated than single paned windows, which means it'll be easier to keep the room/house at a steady temperature. The space between the panes is filled with an inert gas - instead of air. This provides a 'barrier' to slow down the escape of heat from the room. Additionally, the panes are often coated with a microscopically thin layer of reflective material to help retain the heat inside the building.

The windows on a space station are typically made of a special type of glass called borosilicate glass, or a combination of materials such as acrylic or polycarbonate. These materials are chosen for their strength, durability, and ability to withstand the harsh conditions of space, such as micrometeoroid impacts and temperature variations.
Spacecraft windows are typically made of materials such as borosilicate glass or sapphire crystals because they are strong, durable, and can withstand the harsh conditions of space, including extreme temperatures and micrometeoroid impacts. Special coatings may also be applied to the windows to protect against radiation and glare.
the answer to how 'double-glaze windows work':,DOUBLE GLAZING works by trapping air between two panes of glass. This creates an insulating barrier. The benefits of this insulating barrier arePrevention of heat loss through windowsIt will help to Keep noise pollution downIt will help to reduce condensationBy making your home more energy efficient you will save money. By installing double glazing you will cut the heat lost through your windows by half and can save from £80 to £100 per year on your heating bills.
Double-glazing can reduce heat loss through windows by up to 50%. 20mm is the optimum space between the 2 panes of glass; less than this leads to increased heat loss; more than this makes little difference to the level of thermal insulation but does give improved sound insulation.
