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.

How do you detect fog?
Try looking out the window
What do you call the fog that's on your window?
Misting, or condensation.
Why is there foggy windows of an air conditioned bus?
The temperature difference between the inside and outside of the bus causes condensation to build up on the inner surface of the windows - that's what you see as 'fog''Why ARE' - But anyway, it is due to condensation - it is colder outside the bus, making the windows cold, so the warm, muggy, humid water vapour condenses as water droplets on the window. Also, because people breathe out carbon dioxide, it can steam up the water droplets. Maybe try opening the windows.
Why does fog form on bathroom mirrors and windows?
Fog forms on bathroom mirrors and car windows when the water vapor in the air condenses on the glass. This is due to the temperature difference between the glass and the air.
Why do eyeglasses fog up when you come inside from the cold?
That is the reaction of the cold lens meeting with the heat from the inside.
Which passage most focuses on the concrete?
The yellow fog that ribs is back upon the window panes The yellow smoke that rubs is muzzle on the window panes T.s.eliot from love song of j. Alfred prufrock
What substannce makes a window fog up?
It is the moisture leaking through the seal of the window. The moisture collects between the window panes and makes the glass fog up. I do not know how i can fix it. I think you just have to buy an all new window.
Why do car windows fog up?
well it could be because of the heat. if its cold out and you have the heat on in the car, then you will get hot and that will cause the window to fog.
Why are your house windows always foggy?
If the fog is between the panes it is the result of the seal being broken and the dry gas between the panes having escaped. If the fog is on the interior surface of a single pane window, that comes from high humidity inside the house condensing on the cold glass. High humidity can come from inadequately ventilated gas heaters or stoves or it may simply be that you don't run your exhaust fan when you shower. If the humidity is coming from burning natural gas, humidity is not your problem. If you don't have good exhaust, you will likely be poisoned by the carbon monoxide. It is recommended that the exhaust fan be left running for a half hour after a shower. They sell timer switches at the hardware store for that purpose.
Why do car windows fog up when the heat is not on?
It is called condensation, warm and humid inside, cooler outside.
Why does a car window fog up on a cold morning?
The air on the inside of the car is warmer than the air outside.
What can be done about windows that don't defrost in a 1996 Ford Windstar?
If the air coming out of the defrost isn't hot, your heater core may not be functioning. Also, coating the window with an anti-fog formula like Rain-X (sold at PepBoys and the like) may help keep moisture from clinging to it in the first place. I've also found that a credit card is helpful in scraping the inside of windows. try running the heat with the a/c system on, as the a/c removes water from the air, which would normally fog up or ice up the inside of your windows
What physical change is it when the windows begin to fog?
When the windows begin to fog, the physical change is: condensation of water vapor.
1997 Camry - the front and back window fog up and is next to impossible to clear using the vent and air condition system.any ideas?
Turn the conditioner when you are using the heater. It will decrease the humidity level (which causes windows to fog up.)
Why does the inner surface of the car window foggy on a rainy day?
They fog up when water condenses on the surface. If the air inside the car is warmer than the outside temperature you will experience fogging of the inside of the windows. In extreme humidity the problem is worse. You can also see fogging if the heater core is leaking. To dissipate the moisture turn on the defroster.
Why do brand new car windows fog up inside in cold weather?
Windows fog because the glass is cold and the humidity is high inside the car. It has nothing to do with the age of the car. Try turning the fan up to circulate the air better, and if that doesn't work, turn the AC on -- but turn the heat up so it doesn't get cold. That will do it for sure.
