Why are my Windows Steamed up on the Outside?

If you’ve got double glazed windows installed in your property, you should find that (for the vast majority of the time) these represent a great investment, that help you to save money and improve the overall energy efficiency of your premises.

But, you might have spotted a few signs of steam or condensation appearing on the outside of your windows. You may well be wondering what is causing this excess moisture, whether there’s anything you can do about it, and (most concerningly) whether it’s alerting you of any issues with your double glazing.

So, to ease your frustration and answer the question, we’ll be covering this particular area and some tips that you can use to minimise the amount of moisture that you see on your windows.

Why are my windows steamed up on the outside?

In order to solve the problem, you first need to find out what is causing your double glazed windows to steam up. If your windows are condensing on the outside (so on the pane of glass that is exposed to the outside), this is nothing to worry about.

In fact, condensation forming on this side of the window tells you that your window is operating in a way which is super energy efficient – this condensation is forming because these windows are successfully keeping your home warmer than the outside temperature. This is why you’re most likely to spot this extra moisture on the surface of the glass in the winter months.

If your windows are condensing on the outside, but on the pane of window that is exposed to your home’s interior, then this is most likely just being caused by an excess of moisture in the air. To minimise this, we’d recommend that you try opening your windows more frequently.

One of the main signs which allows you to easily spot a problem with your double glazed window is if you can see that it is steaming up between the glass.

In most cases, condensation on the insider of your windows is caused by something in your home. If you are cooking with lots of steam, or having a shower in your bathroom, it’s very common that your windows will steam up. There is no problems with your windows if this happens.

If your windows have steamed up before, it is worth having a good clean of your windows, as lots of moisture can leave streaks and residue on your windows, making them steam up quicker then next time.

Why are my windows steamed up between the glass?

While seeing your windows steam up on the outside is not necessarily an indication of a problem with your double glazing, if you see condensation appearing in between the two panes of glass, then there is an issue with your double glazing which is inhibiting its performance.

The most common issue with double glazing, which causes condensation to form between the glass, is around the seals and window itself. If you have a crack in your frame, the seals are loose, or the window itself is damaged on the outside or inside, this can cause serious issues.
