The space gets filled with an insulating gas like argon or krypton which increases the energy efficiency of the window.
Argon gas windows repair.
However it may only be a short term solution.
Start by checking the border of the window to determine whether there are any gaps between the frame and the wall.
By following a few steps you can be assured that the window can be repaired so it will be in the best condition.
A double pane window is essentially two panes of glass fixed into a frame with a small gap between each pane.
Start by examining the argon windows to get an idea of the full extent of the repair required.
In these dense gases the molecules move very much slower under the impact of thermal energy which means windows with igus filled with such gas will create a much better barrier against heat loss.
If you send out a window professional for an inspection he or she can gauge the current level of argon gas in your double pane windows.
If you can find a facility that has the capability of refilling the space with a dry gas your chances of success are a lot better because it is the moisture inside the cavity that causes the condensation.
Step 1 inspect.
The better solution is to fill the space between panes of glass in the igu with a heavy inert gas such as argon or krypton.
There are two measures of the energy efficiency of your double paned windows known as u value and r value.
Some rv windows are factory filled with argon or nitrogen gas.
The percentage of argon gas in a window shouldn t be a secret.
