Condensation on Windows: How to Reduce and Prevent It

Whether it’s old or brand new windows, there is one issue that turns up in discussions with house owners preparing a replacement: condensation on windows.

If you have older windows that aren’t as efficient as modern-day vinyl windows, they are most likely to fog-up, collect wetness around the sill, or even freeze. Does this necessarily mean the window has to be changed? What if the window has just been changed and the condensation appears to be even worse than with the old windows?

We will show you how to understand and decrease or prevent condensation on your windows in this blog site. In order to get there, we need to start at the beginning with the most fundamental concern:

What is condensation?

Condensation is the procedure which turns water vapour that is present in the air into liquid water. One of the most significant mistaken beliefs that house owners have about condensation is that it is an outcome of a problem with the surface area on which it appears, usually a window or a wall. While problems in these areas can occur as a result of prolonged wetness exposure, condensation in fact originates from the air, or rather moisture in the air.

Why exists condensation on windows?

As the air in a space warms up, it broadens enabling it to hold more wetness. As it cools down once again, it contracts. When the air reaches a cooling saturation point, the excessive moisture turns into a liquid. This is exactly what takes place when the warm air from the within your home is available in contact with the cold glass pane in your window. The air cools rapidly versus the surface area of the window pane and becomes water.

This is most visible on the glass, your windows aren’t the only place condensation can occur. Breaks in your home vapour barrier can permit warm moist air to leakage into wall cavities, condensing there the same way it does on your windows. Since this issue is not apparent to the naked eye, it can go untreated for a long time and result in decaying or mould development over an amount of time. This issue is particularly common in the older with an abundance of older houses.

Condensation on windows is most obvious when the temperature level outside drops quickly, producing a higher distinction in temperature level in between the within and outside air. It is typically most obvious in the early fall when the days are warm and nights are cold. During a damp summertime, the home’s structure can take in a fair quantity of wetness. When the temperature level drops outside, this moisture becomes trapped inside the house, resulting in higher humidity levels and a greater chance of condensation on glass panes.

Where does excessive wetness in the air come from?

  • A household of four can include wetness comparable to 30 or 40 litres of water each week to the environment in your home.
  • Showering, cooking, bathing, and cleaning can include 15 to 20 litres weekly.
  • Drying clothing inside can include 10 to 15 litres per week.
  • Naturally, another considerable contributor to high levels of humidity is your family devices and even your ventilation system. That’s why kitchens and bathrooms are locations with a higher opportunity of condensation.
    During the wintertime, a proper level of humidity indoors is considered to be in between 25 and 40%.

How to prevent condensation from forming on windows?

Exactly how to fight condensation in your house depends upon just how much condensation there is, the condition of your existing windows, your vents, and so on. In other words, it has to do with balancing the air flow system in your whole house. The best fix for your condensation issues may be in a combination of fixes.

In essence, avoiding condensation is about 3 primary elements: minimise the level of humidity in your house, vent the damp air out of your house, and distribute air inside your house appropriately to lower the and maintain appropriate humidity levels.

Lower your thermostat. As we discussed above, warmer air consists of more wetness. If you are like the majority of homes, you can probably manage to turn the thermostat down a degree or two and still be comfortable. As a result, you might see a reduction in humidity and condensation.

Use your fans. Your devices, like the stove and dryer, can create a lot of humid air. Exact same chooses your shower. Ensure that these areas and devices are vented to the outside of the house. Run a vent fan in your bathroom when you shower and turn on your range hood while cooking.

Unclog your vents. A lot of times the biggest problem with airflow is a man-made one. Positioning furniture above or straight in front of the vents prevents air from dispersing correctly, and impacts the blood circulation in your spaces. Same goes for the return vent that takes the air back into the system. Ultimately it is all about making the air move through and around the whole house for best outcomes.

Clean your vents and change your filters. Dust on your vents or return grill can be a sign that the air walking around your house is not as clean as it ought to be. Physically cleaning the dust off can cause increased airflow. Replacing or cleaning the air filter not only provides your household with cleaner breathing air, but it also makes your heater run more effectively. Some companies advise changing the filter as typically as every two to three weeks, so you may want to add it to the list of your regular tasks. At the very least try to check on the health of your air filters month-to-month. This will be a good sign of their health and total furnace efficiency.

Seal dripping ducts. According to Energy Star, about 20% of the air that moves through the duct system is lost due to leakages, holes, and poor connections. That’s one-fifth of your heating costs disappearing into the ether. By redirecting, sealing, or repairing the dripping ducts you can improve the flow of air and boost circulation.

Flow the air inside your home. As we stated previously, colder air means less humidity. Among the quickest ways to cool the air in your home is by merely opening a door or a window. This might not always be ideal because of the weather condition, but you must consider aerating the air in your home daily, even if for a couple of minutes.

Get a dehumidifier. One service that seems to work well for everybody who experiences above normal condensation levels in their home is making use of dehumidifiers. These units are fairly low-cost and you can find one in your local DIY store quite cheap. This is likewise a good service for house owners with new windows that experience condensation, where other locations in your house may not be as significant in adding to moisture on windows.
