When to know your window is damaged.

Where it is exceptionally humid. The water vapour cools on the inside of the glass against the surface and condenses across it. The condensation can be a real problem as it leads to the build of black mould inside the window, which can cause health problems for the occupants of the home and threaten to damage the window further.

Luckily, if condensation is occurring on the inside, it is more likely that you need to replace the seal rather than the glass. The seal is generally the first part of the window because it’s just a thin piece of rubber, but it is an essential element of a double glazed window.

The sun blasting through the window to a very cool room in the middle of summer might cause it. It happens because the window is trying to contract and expand simultaneously. Molecules get closer together when they’re cold and drift apart with heat. When something as fragile as a single pane of glass does this, it is inevitable that damage will be caused.

With double glazing, you’re a lot less likely to have this issue because of the thermally insulating gas separating the two sides of the window and keeping the temperatures clear of each other. However, if your double glazing has blown, then once the cool air comes to replace the insulating gas, you may find that thermal cracking occurs on one or the other pane of glass. Your window will have had to deteriorate significantly before this happened, and you’ll likely have had the glass replaced before this happened, but if you choose to ignore it, this could happen.
