It is a sight that we have all seen. You wake up on a cold winter morning, open the curtains, and instead of a clear view outside, you are faced with windows that are covered in droplets of water. Condensation on windows might seem like a small issue, but it can lead to bigger problems down the line.
Every day, we breathe more than 15,000 times, and it is that breath that makes up a big part of the condensation that you see on your windows in the morning.
The amount of water vapour in our breath is most obvious on a cold day – when you breathe out what seems like clouds of steam. The reason you can see the vapour on a cold day is that the air temperature is sufficiently low for the water in your breath to condense, however that vapour is always there – even on a hot day. You can test this by breathing out once on a windowpane, and you will see the water vapour condense almost instantly.
As you sleep, your breathing slows down, but the concentration of water in your breath does not change, and on a cold night, when that moisture laden air comes into contact with the cold glass of your windows, it condenses to form the beads of water that you will see in the morning. If you sleep for 8 hours, you will breathe thousands of times, and while not every drop of water you produce ends up on the glass, enough does to cause a build-up.
Like all types of condensation, if you do not act on window condensation, it can lead to damp. If the moisture is allowed to run down onto your windowsills and settle, it can form small pools of water that will eventually soak into surrounding walls and wood causing damp patches and rot.
Damp is a problem anywhere in the home, but in bedrooms it is particularly harmful. Damp can lead to the growth of dangerous black mould which can affect your health and cause severe allergic responses.
The first step to handling condensation on your windows is simple – wipe them down each morning to prevent the water from having an opportunity to settle.
Wiping down windows each morning can be a bit of a chore, but it is important in preventing damp. But it is important to remember that it is not a permanent solution. If you really want to prevent window condensation and protect your home from damp, it is important to look at ways of reducing the humidity in your air.
One of the reasons why humid air builds up in our bedrooms at night is that there is less airflow in the evenings. During winter we will normally have windows closed throughout the night, and without people moving in the house, the air gets a chance to become still, so it is more likely to come into contact with the cold surfaces where it condenses.
The only solution to window condensation is to install a ventilation system in your home that works day and night to keep air moving around. Modern Positive Input Ventilation systems work by drawing fresh filtered air into your home from outside to replace the moist air. This reduces overall humidity and because the air is constantly moving, it no longer has the chance to cause condensation.
