How to prevent condensation on aluminium window frames

Whether you’re looking to enhance your home aesthetically or replace old wooden or PVCu windows, aluminium window frames are the perfect choice, offering high performance, security, thermal efficiency as well as style.

Why does condensation form on aluminium windows?

Usually, condensation on windows is caused by a build up of excess moisture. With all air holding moisture to some extent, it is common for condensation to form inside the home. However, the higher the amount of moisture in the air, the higher the chance of condensation forming, meaning bathrooms and kitchens are more susceptible to condensation.

When the warm air containing moisture, comes into contact with a cold surface, it precipitates, this is then deposited as droplets of condensation.

Generally, this happens more in winter as there’s a bigger temperature differential between inside and outside. Also, windows are less likely to be to be open in homes which reduces ventilation. This then creates the perfect conditions for condensation to form.

Why is condensation bad?

While condensation itself isn’t a problem, if it is not treated, it can cause damp patches to form, where subsequently mould, spores and mildew can grow. This can be bad for health as well with some people being sensitive to them with symptoms including nasal stuffiness, throat irritation, coughing, eye and skin irritation from its presence.

A hidden effect of condensation on windows is that as the sun appears on windows, it should be heating our homes interior. Instead, the suns heat is being used to evaporate window condensation while also putting the moisture back into homes and raising the humidity level even further.

If left untreated, even minor water damage can leave severe stains and damage on drywall as mould eats or digests whatever it is growing on. This could eventually cause structural damage to building materials and in turn cost homeowners money, and potentially reduce a home’s value.

Is all condensation on aluminium windows bad?

Firstly, it must be established where exactly the condensation is forming on the glass, for example if it’s it on the inside, outside or in between the glass itself. This is a huge factor as to whether the condensation is a serious issue or not.

Condensation on the outside of windows

Condensation on the outside of windows is generally an indication that your windows are doing exactly what they are designed to do, as they are sealing and insulating your home. This type of condensation typically occurs in summer, as it happens when the air outside your home is humid and warmer than your window glass. This means that outside humidity is staying outside. It can be a bit annoying as it can stop you from looking out of the window, but it soon disappears in the sun.

Condensation on the inside of windows

Condensation on the inside of windows is usually a red flag, unless it is caused by steam coming from the bathroom, kitchen or other similar events. However, if condensation develops on the interior side of your window without any direct cause, it could mean that your home’s humidity is too high, so the glass becomes colder than the temperature of your home. To solve this issue, it is a good idea to improve ventilation before it causes any further issues for your property. This can be as straightforward as opening the window for a while every day, or installing additional air bricks or even HVAC.

Condensation between the panes

If condensation forms in between the window’s glass in double or triple glazed units, this usually means that your insulated glass unit is no longer sealed. If this occurs, it means that the glass unit is no longer providing the full range of benefits it used to, the window may be leaking, and the insulating air (argon or krypton) has been lost. The quickest and easiest option to resolve this issue is to get the insulated glass unit replaced, or possibly even the entire window, if there is widespread failure.

How to stop condensation from forming on your aluminium window frames

Tackling condensation on the inside and outside of your windows isn’t easy and can be a continuous problem. However, there are things you can do to reduce condensation:

  • Keep drying your washing to one room only

Many people dry their washing on radiators and clothes horses indoors in the winter, but this action can release a lot of moisture into the air. To limit this moisture build up, try and keep drying your washing to one single room only and keep the door to this room closed to prevent the moisture spreading throughout your home. It could also be beneficial to keep a window in the room open slightly to increase ventilation.

  • Trap humidity where it is created

Most excess moisture is created in the bathroom and kitchen with hot showers and steaming cooking pots all releasing moisture that quickly spreads throughout the home. A simple way of stopping this moisture from creating condensation is by keeping the doors to these rooms shut, using an extractor fan wherever possible and opening windows after baths, showers and cooking.

  • Dehumidifier

Not only are dehumidifiers good for controlling condensation but they are also great for eliminating mould. They actively reduce humidity in homes by decreasing the amount of moisture that the air contains. This makes it harder for condensation to deposit on surfaces.
