Why Windows Fail 
There is much more to insulated glass unit (IGU) failure than common window legend tells. The 'ruptured' seal that allows moisture into the sealed unit is, in most cases a small breach in the airtight seal.
During the lifespan of a sealed unit, the window will take quite a beating. While manufacturing, transport, installation, exposure and building pressure can all compromise an IGU's seal integrity, it is the day-to-day atmospheric pressures acting on the unit, like temperature, that take the biggest toll. Among these stresses, radiant heat from the sun is by far the most destructive.
The great majority of failed IGU's are found on the sunny side of the property. Why? This is a factor of temperature pressures and time. When the suns direct energy hits a window, the rise in temperature between the panes of glass makes the air molecules more active, increasing pressure in the chamber, on the glass and on the seals. Then as the temperature drops, a negative pressure is exerted on the glass and seals.
