The air inside your home is generally more humid than outside air, which can cause moisture to build up between the glass panes. It's a problem that can dramatically reduce the efficiency of your double glazing. Ignoring this problem will only result in increased energy bills and damaged windows. Condensation on the exterior If you notice condensation on the outside of your window frames, don't worry, this is completely normal. Window condensation on the outside is caused by cold glass coming into contact with humid, warm air. The air's moisture can't hold itself as a vapour and, when it comes in contact with a cold object like glass, it turns into water droplets (known as condensation). Exterior window condensation is most prevalent in the morning, when temperatures are low and sunlight hasn't warmed the windows enough to evaporate the water.

The downside is that excessive condensation from the outside of your windows can leak down and cause peeling paint, blistering or cracks in the frames of your windows.

You might also consider the use of a window coating that's hydrophobic. This is a clear material that makes water roll off the windows instead of sticking.
