But first:
What is Window Condensation and why is it bad?
Window condensation is the accumulation of moisture on your windows, which can have a number of negative effects on your home.
Not only does this cause unsightly streaks, but it can also lead to mold growth, peeling paint, and an overall decrease in your home’s energy efficiency.
And according to everest.co.uk, condensation can also damage windows and furniture. This is also known as a red flag of window insulation quality.
Window condensation is even more common in the winter months, when the temperature difference between indoors and outdoors is particularly large.
So overall it is bad, but what are the different types of condensation and why is its reasons and how can we stop it, let us see..
Types of Window Condensation
Window condensation is a normal problem for homeowners and renters alike. This can create an unsightly mess and even lead to mold growth.
Knowing the different types of window condensation will help you pinpoint the exact cause and help you get to a solution faster than average.
So here, we will explore the different types of window condensation:
1. Exterior Condensation
This type of condensation usually forms on the outside of your window. The main cause of exterior condensation is excessive humidity and poor ventilation in the area around your windows.
This kind of condensation is more common in climates with higher temperatures and humidity levels.
2. Interior Condensation
As it name suggests, this type of condensation cause on interior of the window. This is typically caused by warm, air humid inside the home coming into contact with a cool surface on the window. This can cause more serious damage to the window, such as rot, mold, and mildew.
3. Condensation between Glasses
The third type of window condensation is condensation between the glass and is also called edge seal failure.
This occurs when the seal between two glass panes fails and water accumulates in the airspace between them.
This type of condensation is usually caused by improper installation and can often be repaired by a professional.
What Causes Condensation on Windows?
So, what causes window condensation in the winter? Let’s look at some possible reasons why your windows may be collecting excess moisture:
- Poor Insulation – If your windows are poorly insulated, warm air can escape through them and condense on the glass.
- Excessive Humidity – When indoor humidity levels are too high, it can lead to moisture build-up on windows, walls, and other surfaces.
- Cold Weather – Low outdoor temperatures can cause moisture to form on your windows if the indoor temperature is warmer than outside.
- Poor Ventilation – Without proper ventilation, warm air becomes trapped inside your home and condenses on cold surfaces like your windows.
- Drafts – Leaky windows or gaps around the window frames can allow cold drafts to enter your home, resulting in condensation.
- Rain or Snow – When rain or snow lands directly on your windows, it can create condensation as the moisture evaporates.
- Overwatering Houseplants – When you overwater houseplants, the excess moisture in the air can form droplets on cold windows.
Now that you know what causes window condensation in winter, let’s take a look at how you can prevent it. With some simple steps, you can help keep your windows dry and reduce the risk of damage to your home.
How to Stop Condensation on Window?
Wintertime can be extremely cold, and if you live in an area with low temperatures for a long period of time, there is nothing worse than waking up to find fogging up and condensation on the inside of your windows or mirrors.
Although it may be very gross, it is actually not very dangerous to health or your household items; In fact, preventing it is quite easy.
Here are some tips to help prevent window condensation this winter.
1) Make sure to use a pan lid while cooking
It may seem like a small thing, but using a pan lid when cooking can help reduce window condensation during the winter. By using a lid on your cooking pan, you can prevent moisture from building up on your windows and walls.
This is because the lid helps to trap moisture and steam within the pan, preventing it from entering the air and sticking to your windows. After cooking, it’s best to leave the lid on your pan until the food has cooled.
This will help ensure that any remaining moisture is trapped inside the pan and doesn’t escape into the air. Additionally, be sure to wipe down your stovetop and walls after cooking as this will help remove any excess moisture from the area.
2) Use a dehumidifier
window condensation is not at all a rarest problem, especially during the winter months. It can also be caused by high levels of moisture in the air that condenses on the surface of a cold window.
In my opinion, the most effective method is to use a dehumidifier in your home. The dehumidifier will remove excess moisture from the air, reducing the likelihood of condensation forming on your windows.
It is important to note that you should only use a dehumidifier when the relative humidity inside your home is above 50%.
Any less and it won’t be effective at reducing window condensation. You can monitor the relative humidity in your home with a hygrometer, which is a device that measures humidity levels.
3) Ventilation is key
Ventilation is key when it comes to reducing window condensation. The most important thing to remember when preventing window condensation is to always keep your home properly ventilated.
One of the most effective ways to do this is to open the windows for a few minutes each day to allow fresh air to circulate around your home. This helps reduce the amount of moisture in the air that can cause condensation.
You should also make sure any exhaust fans such as range hoods and bathroom fans are on when needed, as these can help remove excess moisture.
4) Don’t dry your clothes indoors
One of the easiest ways to prevent window condensation is not to dry your clothes indoors. Hanging wet clothing near windows can allow warm, moist air to enter the room, increasing the likelihood of condensation forming.
Instead, try drying your clothes outside or in a well-ventilated area away from windows and radiators.
5) Avoid Overwatering Houseplants
Overwatering can create excessive moisture in your home and contribute to window condensation.
Make sure you are not over-watering your plants. Check for signs of over-watering such as wilted leaves or fungal growth. If you see these signs, cut back on how often you’re watering your plants.
6) Completely Cover Your Aquarium or Fish Tank
Covering your aquarium and fish tank completely with a glass lid or plastic sheet will help minimize the problem you may encounter.
Doing so will force cool, dry air out and trap warm, moist air inside your home. But make sure the lid or sheet is properly sealed, as any cracks can allow cold air to get in and cause condensation.
And covering an aquarium or fish tank does not any high effort, time and money.
7) Check your roof and seal any water leaks
One of the most unusual issues behind window condensation is water seeping into the home from the roof.
To prevent this, it is important to check your roof for any signs of water damage. Look for any missing or broken shingles, or any gaps around flashing, vents, or chimneys.
If you see any damage, seal it as soon as possible to prevent water from getting inside.
