Why Are My Double Glazed Windows Covered in Condensation?

why are my double glazed windows covered in condensation

When it’s cold and wet outside, the last thing you want is for the inside of your home to be the same. Sadly, many homeowners still find themselves asking the question, why are my double glazed windows covered in condensation?

Far too many people in the UK suffer from damp, draughty, and mouldy homes, with little idea what to do about the problem.

The issue is a lot more widespread than most homeowners think, with around 44% of homeowners living in a home with draughts, and 38% of people living in homes with condensation problems.

The condensation that gathers on windows is partially to blame for problems with mould, making a living environment less comfortable, appealing, and safe for your family. So, what is the answer to condensation on double glazed windows, and what can you do to solve the problem? It’s time to find out…

What Causes Condensation to Appear on Double Glazing?

When looking at the issue of condensation appearing on your double glazed windows, there are three types of condensation to be considered; exterior condensation, interior condensation, and internal window condensation.

While interior and internal condensation are the big problem causers, exterior condensation means something a little different.

Exterior Condensation

Believe it or not, the little beads of water that appear on the outside of your windows is a promising sight. This means that your glazing is working, and your home is losing less heat.

While the condensation is not the most attractive thing, it shows that the external temperature of your glazing is lower than the dew point.

In modern units, like those with triple-glazing, where the internal pane of glass is normally made from low-e glass, this will become a more regular occurrence. As your home retains more heat the external glazing stays cold and condensation appears externally.

Interior Condensation

If there is condensation inside your home, not just on your double glazed windows, then it can be a serious problem. Interior condensation demonstrates that the surface temperature of your glazing is low, and that your room has a high content of water vapour.

When warm air hits a cold window, the condensation will form. If you have a high humidity in your home then you’ll experience significant condensation issues. This is why many people see the formation of condensation in their bathrooms and kitchens, where water is more likely to be circulating.

Internal Window Condensation: The Additional Antagoniser

Seeing condensation inside your glazing is a troubling sight, especially since it is really not supposed to be there.

If left untreated, internal window condensation is going to cause some serious problems to the structural integrity of your window and is already an indication that your window is not performing as it should.

So, why exactly are your double glazed windows covered in condensation on the inside? Internal window condensation indicates a problem with the seal of your window.

The vacuum compartment between the double or triple glazing is supposed to be sealed; however, when this seal breaks, air and moisture can easily get in, leading to all manner of additional problems that can be incredibly costly to fix.

This reduces the whole energy-efficiency of the window, meaning you’re not going to be saving much energy in your home.

Is There a Better Glazing Type to Stop Condensation?

To reduce condensation in the home, your property should have adequate heating, and plenty of ventilation. The heat will prevent the problem of cold windows, allowing them to work properly, and ventilation will prevent the build-up of moisture in the air.

However, upgrading your windows could also give you a helping hand. After all, it’s not always viable to turn up the heating, and nobody wants their windows wide open on a chilly day. One of the best window types on the market to help reduce condensation problems is triple-glazing.

As we have already covered, the low-e glass inside triple-glazing can help your home to retain more heat. This helps to warm your windows up, preventing the temperature dropping low enough for condensation to become a regular problem on the inside of the windows.

The whole triple-glazing system is built with optimum heat retention in mind, with duel vacuum chambers, and glass with high insulation properties. This combined with a strong frame, with a sturdy seal, should help you to see an end to damp, dripping windows.
