This is due to the high insulating value of double pane low e glass with argon.
Double pane windows condensation.
Double pane windows also called insulated or thermal windows are made with two.
It is not uncommon in areas with high humidity to have condensation on the outside of the windows.
The wood gets too wet and starts to rot and eventually the glass seal breaks down.
In humid climates wooden window frames are often the culprit.
How to fix condensation in double pane windows the problem with tempered glass.
The windows are working as designed.
With double pane windows you should be able to sustain somewhere around 50 to 55 percent relative humidity indoors on a 40 degree night and not get condensation on your windows.
The outside glass actually gets colder then the air allowing condensation to form.
Condensation on the inside of windows because glass surfaces are usually some of the coldest parts of your home condensation appears on windows first.
Double pane windows have a layer of gas usually argon or air trapped between two panes of glass that acts as insulation to reduce heat loss through the window.
Luckily interior and exterior window condensation is not a sign of a faulty window and there are many ways you can reduce the condensation in your home.

The appearance of condensation between a double pane of glass indicates that the windows are not doing their job properly.
When condensation between double pane windows forms the seal on the glass is broken.
A critical temperature known as the dew point exists where these water droplets will be forced so close together that they merge into visible liquid in a process called condensation.
Replacing double pane windows.
New windows also tend to help reduce condensation on the glass because the internal pane of glass is that much warmer than single glazing so the moisture in the air doesn t condense on it helping keep the windows mist free.
The air tight seal holding the insulating gas inside has failed letting all the insulating gas out.
In these situations it s as simple as replacing the insulated glass unit.
Drill a small hole on the bottom of the window centered in between the 2 panes of glass use a pipe cleaner or coathanger wrapped in a thin layer of fabric and insert into the hold move the object around to.
