Why do new windows often have two panes with space between them?

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.

Why do new windows have two panes of glass with space between?
insulates and reduces heat passage through the layers of glass.Read more: Why_windows_in_some_homes_have_two_panes_of_glass_separated_by_a_layer_of_air
Is Double Glazing a good insulator?
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
What does the process of double glazing do?
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

What are the windows on a space station made of?
Tempered Glass. The panes are very thick (2 to 3 inches) to assure no breakage.
Why do windows fog up inside window panes?
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.
What are space crafts windows made out of?
Very thick thermal panes windows, which is glass and acrylic thermally bonded together. They may very well be double glazed also.
How does double-paned windows glass regulate indoor temperature?
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.

How double glazing is a good insulator?
The big insulating value of double glazing has to do with the space between the two panes of glass. If it's filled with air, that's good, because air is a poor conductor of heat. For even greater insulating value, the space between the panes can be filled with argon gas instead of air. Argon is an even worse conductor of heat than air is.
Why are thermopane windows usually made with two layers of glass separated by an air space?
the air space is there for a reason. once the material changes its normal lenght, it probably will need space. this is due to temperature, also know as specific heat capacity The air space causes the window to transfer less heat. Glass is a relatively good medium for conducting heat, while air is a poor conductor. With single paned windows, heat can easily flow from the inside of your house to the outside environment, wasting energy. However, since air is a poor conductor, heat does not transfer as well through thermopane windows. +++ Is "Thermopane" a trade mark? The generic term is "double glazing", and windows for very cold climates are often tripe-glazed, i.e. with 3 panes.
What feature of double glazed windows makes them good insulators?
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.
