Argon Filled Windows Condensation

It is this sealed space that gives the window most of its thermal performance.

Argon filled windows condensation.

The spaces are filled with argon or other gasses to slow the transfer of heat through the window. Gases like argon are preferable to air because air contains moisture that can condense on the inside of the glass units making the window cloudy. Argon gas windows are energy efficient due to the density of argon gas being heavier than oxygen. In this case the insulation barrier reduces the heat transfer from the hot air outside so your home will stay cooler inside in the summer.

The short story is that the introduction of argon into the space between two panes of glass creates an insulation barrier. Sometimes a basic clean will take care of the problem. You ll notice this only when the window has lost a significant portion of the gas as condensation will build up inside the product without the argon gas. Another trademark problem of double pane windows that have become exposed to drafts and likely lost all the argon gas is when condensation builds up on the inner surface.

If an argon filled window has even the smallest gaps in it the argon gas that escapes can be replaced by moisture laden air. Double pane windows also called insulated or thermal windows are made with two panels of glass sandwiched over a spacer and sealant creating a space between the panes that is filled with air or with a gas usually argon or krypton. This saves you on maintenance and replacement costs. By keeping the heat or cold air inside the house the windows provide a better insulator than windows with oxygen between the panes.

Air also insulates less effectively than gas fills. In this way the gas between the double paned windows are less effected by convection currents and drafts. In general the lower the u factor the better job a material will do at insulating. Just like the insulation in the walls of your home argon gas filled windows keep the heat in and the cold out.
