In short, your new double glazed windows should not get condensation. However, it’s important to know what’s normal and what isn’t when it comes to condensation. You may assume that if your windows aren’t clear all the time, then there’s something wrong with them. This can sometimes be the case, but only when talking about condensation between the two panes of glass.
To make sure you don’t continue with failed double glazed windows or worry unnecessarily about a ‘problem’ that is actually perfectly harmless, we’ve put together our comprehensive guide to condensation below.
Your new double glazed windows have condensation on the outside
Condensation on the outside of your double glazed windows occurs when the air outside is warmer than the temperature of your double glazing. Outside condensation means your windows are not allowing any heat transfer, so, if you have some condensation on the outside of your windows – relax! It just means your double glazing is doing a great job of insulating your home.
If you are bothered by how condensation looks on the outside of your double glazing, you could simply wipe it away if your windows are within reach. However, the best option is to simply wait, as the condensation will usually disappear when the sun shines directly on your windows.
Your new double glazed windows have condensation on the inside
If condensation forms on the inside of your double glazing, it is usually the result of steam from your shower, kettle, or hot pots and pans used whilst cooking. This is a natural phenomenon where water vapor turns back into liquid when it comes into contact with something cooler in temperature, like your double glazing.
However, condensation on the inside of your double glazing can sometimes indicate above-average humidity levels in your home and you may have a ventilation problem. If water vapour has nowhere to go, it will condense your windows, as well as your furniture, in carpets, and on walls. Excess moisture around the house can be very damaging to your home and to your family’s health. Encouraging air flow and letting fresh air in will naturally improve ventilation and lessen the chance of condensation on the inside of your windows.
Quick and easy ways to ventilate your home
- Open doors and windows.
- Dry laundry outside, avoid the tumble dryer.
- Open your windows trickle vents if you have them.
- Put your windows on the night vent facility keeping your home secure whilst still allowing airflow. (Especially if windows are behind a thick curtain/blackout blind or above a radiator etc.)
- Keep internal doors open (when not cooking/showering).
- In winter, open your windows periodically (Only when the central heating is off!)
You have condensation between the panes of your double glazed windows
The appearance of condensation between the panes of your double glazed unit indicates that the windows are not doing their job properly. The air-tight seal holding the insulating gas inside has failed, letting all the insulating gas out. When this occurs, water vapor can get between the two panes.
This means your double glazing can collect moisture, which can lead to further damage to the window, whilst wasting drastic amounts of energy as you attempt to heat your home and replace the heat being lost. New double glazed windows should not be collecting condensation between the panes, and if you have condensation between your panes, you definitely need new windows.
