Misted windows are a real pain for homeowners, not just for the appearance of your home but also could be a sign of bigger problems. Understanding the causes of misted windows and how to fix them is key to keeping your windows working and looking good. In this post we’ll look at why windows mist and how to prevent and fix this problem.
Why Misted Windows
- Failed Seals
Double and triple glazed windows rely on airtight seals to keep the insulating gas between the panes. Over time these seals can fail due to age, poor installation or exposure to the elements. When the seals fail, moisture can get into the space between the panes and mists; therefore, when you wipe the window, you are unable to get rid of the mist.
This causes heat to be lost, making the energy efficiency of the windows poor and increasing heating bills.
- Condensation
Condensation is the most common cause of misted windows and occurs when moist air meets a cooler surface, like a windowpane. This is more common in areas of high humidity or where there are big temperature fluctuations. The condensation sits on top of the glass.
- Not Enough Ventilation
Poor ventilation in your home can cause high humidity levels which can lead to condensation on windows. This is often a problem in rooms with high moisture levels like bathrooms, kitchens and laundry rooms.
- Temperature Differences
Big temperature differences between the inside and outside of your home can cause condensation. For example in winter the warm indoor air meets the cold window surface and mist forms.
Misted Windows Solutions
- Improve Ventilation
Increasing ventilation in your home can reduce condensation. Use extractor fans in kitchens and bathrooms, open windows regularly to let fresh air in and consider installing trickle vents in your windows to maintain a constant airflow.
- Dehumidifiers
Dehumidifiers can reduce the overall moisture in your home and therefore reduce condensation. Place them in rooms that are most prone to humidity like basements or bathrooms.
- Repair or Replace Failed Seals
If the misting is due to failed seals in double or triple glazed windows the solution is to replace the affected units. We specialise in replacing the double-glazed unit (DGU) as it is more cost effective over replacing the whole window, resolves the mistiness and restores energy efficiency to the window.
- Upgrade Your Windows
Older windows with single glazing or old double glazing are more prone to misting. Upgrading to modern energy efficient windows with better insulation can prevent condensation. Look for windows with low emissivity (Low-E) glass and gas filled panes for better performance.
- Maintain Indoor Temperature
Keeping a consistent temperature inside your home can reduce condensation. Use your heating system to maintain a steady temperature and avoid sudden temperature changes that can cause misting.
- Insulate Your Home
Insulation can keep your home’s temperature steady and reduce condensation on windows. Make sure your walls, roof and floors are well insulated to reduce temperature differences that cause misting.
- Window Films
Window films can act as an extra barrier against moisture and temperature changes to reduce condensation. They are easy to apply and add an extra layer of insulation.
Misted Window Prevention
To prevent misted windows in the future:
- Check Seals Regularly: Inspect your window seals regularly for any signs of wear and tear. Fix minor issues before they become bigger problems.
- Use Window Coverings Wisely: Heavy curtains and blinds can trap moisture against the window pane. Use breathable window coverings and leave some space for air to circulate.
- Monitor Indoor Humidity: Use a hygrometer or humidity meter to monitor indoor humidity. Keep it between 30% to 50% to reduce condensation. There are many affordable options available on Amazon here: https://www.amazon.co.uk/humidity-meter/.
Misted windows are a common problem but one that can be solved. By knowing the causes and solutions you can have clear and functional windows and a more comfortable home. Whether it’s improving ventilation, repairing seals or upgrading your windows taking action will prevent misted windows and keep your home energy efficient and looking good.
