During the winter months, you’re more likely to see condensation form on the windows of your home or inside the cavity of old double glazing units.
It’s actually possible for condensation to appear on any surface of window glass – inside your property, between double glazing panes, or even on the outside of your house.
What it means depends on where it forms, but generally the cause is a combination of humidity and a difference in temperature across the glass.
Here are the common causes of condensation on windows and some of the ways to reduce it.
Inside your home
Condensation on the inside of windows is often a sign that it is cold in your house, especially in the mornings after a particularly cold night or if you haven’t had the heating on.
It forms when water vapour in the air inside your home cools down on the cold surface of the glass, turning it back into liquid water droplets.
This can be annoying and unsightly, and can promote mould growth if left untreated, but there are a few things you can do beyond just wiping up the water every morning.
If possible, keep your home a little warmer so there’s less risk of condensation forming, and try to monitor and manage the humidity levels in the air in your home too.
Double glazing windows are another way to tackle condensation – the insulated layer between the panes helps to keep the heat in, so the glass does not get as cold and less condensation forms on it.
Inside double glazed windows
Condensation between the panes of double glazed windows is a sign that the unit is no longer sealed properly and moisture is creeping in.
If your double glazing is leaking moisture in this way, it’s probably time to think about replacing it – newer glass and especially triple glazed windows can be much more energy efficient, on top of getting rid of the condensation problem.
Remember that both temperature and humidity affect condensation, so it’s a good idea to ventilate your home when the weather is dry outside, to give the natural moisture generated within your household a chance to escape through the open windows.
Inside secondary glazing
Secondary glazing – where a second layer of glass is retrofitted to existing single glazed windows – does not have the same seal that you get with a true double glazed window unit.
Because of this, it’s more likely that moisture will enter the cavity and condense on the interior surfaces of the glass.
There’s not much you can do to prevent this from happening, other than to install sealed double glazing insulating glass windows.
Doing so can save energy and money, help you to control the humidity inside your home more easily, and reduce condensation on windows as a result.
