How to Stop Condensation on UPVC Windows | Eurocell

How to stop condensation in your home

Condensation on windows is not an uncommon problem and can unfortunately impact the look and feel of your home, as well as the temperature.

With all the efforts taken to keep the heat in with energy efficient windows, we can end up shutting the moisture in our homes, which results in condensation. And despite double or triple glazed windows reducing condensation by insulating rooms from the cold outside, it can on occasion, be part of the problem.

If you’ve got an issue with condensation and you’re unsure on how to resolve it, here are some top tips from the team at Eurocell Home on how you can stop getting condensation on your windows.

One of the most effective methods of combatting condensation is to increase the ventilation in the home or specific room. Something as simple as partially opening a window or, if your windows have them, the trickle vents at the top of the window frame can make a huge difference to the ventilation.

It might seem as though you’re letting the warm air escape out of the room, but in fact you’re replacing warm, moist air with cool dry air, which is in fact cheaper to heat in the long run.

If that isn’t effective in getting rid of the condensation problem, there are alternative steps you can take. These methods depend on what kind of condensation you have in your home, what room it’s in and what the cause of it is.

Firstly, do you have condensation appearing on your window frames? The types of window frames which normally have condensation appearing on them are steel or aluminium. However, modern profiles now have a thermal break built into them, helping to prevent heat escaping through the frames.

Ultimately this means any condensation is normally the result of poor fitting, or a failure within the frame itself. To resolve this issue, we suggest contacting the manufacturer or installer who will be able to help resolve the problem.

Condensation on the inside of your windows

If you have double or triple glazed windows and condensation appears on the inside of your windows, there are a few steps which you could take to try to get rid and stop the condensation.

1. If it’s in your bathroom, ensure an extractor fan or heat exchange unit is fitted.

2. In cold weather especially, keep your heating on a low setting, even when you’re out of the house. Heating up your home by just a couple of degrees can be enough to prevent any condensation.

3. If you have curtains in the room, make sure they are hung at least 15-20 cm in front of your windows. By doing this you will allow for warm air to circulate between the curtain and window, keeping the glass surface warm enough to stop condensation forming.

4. Do you have a fireplace? If you do and it’s blocked, you could consider fitting wall vents to increase the airflow in the room. If you have a gas fire, check the back plate has vent holes below the fire, unless the vent holes are provided for in the design.

5. If you’re getting condensation on your kitchen windows, it’s worth getting an extractor hood fitted, and if possible, make sure it vents to the outside.

6. Have draught-proof internal doors and ensure they’re kept closed – in particular those from bathrooms or kitchens. It’s not possible to stop moisture circulating through your home but limiting the movement will certainly help.

7. Finally, wherever possible make sure radiators are fitted directly beneath windows. This will help to increase the surface temperature of the inner glass on the window and so, prevent condensation appearing.

Condensation on the inner panel of the glass 

When condensation appears on the inner panel of the glass, this can be more difficult to manage, and the condensation can’t simply be wiped away.

When this occurs, it’s likely because of the double glazing not providing an airtight seal between glass layers. This means air can creep in between the glazing panels, and when it meets the cold outer glass window it produces condensation.

Here are a few simple steps on how you can prevent condensation on the inner panel:

1. Make the seal between the secondary glass and original single glazed window as airtight as possible. This will help to stop any air creeping through.
2. Using desiccant packs, you can help to keep the moisture out. Used as a form of humidifier, they absorb any moisture, keeping your windows clear.
3. If possible, try to limit the number of times you open the secondary glazing, especially in cold weather. This will help to limit the volume of warm, moist air that gets behind it.
