Misty windows can be a real issue for homeowners. Condensation can be annoying because it restricts the views that we like to have of our gardens and outdoor spaces. Furthermore, condensation can also present certain risks to the home. It can damage the installation itself by a build-up of excess water if it isn’t wiped away properly and, if not treated, may cause the build-up of mould, which can cause health issues to the residents of the home and cause potential damage through damp.

what causes double glazing to mist up

So how can we clear the morning mist from our double glazed windows? Assuming that it’s on the inside of the window, there are a few options we can go with:

  • Maintaining proper ventilation and airflow throughout the home.
  • Isolating high humidity rooms, such as the bathroom, from the rest of the house.
  • Drying your clothes outside when possible or near an extraction fan.
  • Keep the windows open when you’re cooking.
  • If you’re able, purchase a dehumidifier to keep moisture under control.

How to maintain good airflow in the home

Various kinds of windows are best suited to maintaining consistent ventilation throughout the home. Tilt and turn windows, in particular, are very good at giving the homeowner full control over their home’s ventilation due to their two mechanism opening system. Tilt and turn windows can either open slightly through a hinge on the bottom to maintain a consistent airflow that keeps the rain out. Alternatively, they can open through a hinge on the side of the window to open the window more fully.

Like most windows, tilt and turn come with trickle vents at the top of the window. Trickle vents are now mandatory for all windows as per new government regulations coming into practice in June 2022. The regulations ensure that every home is able to maintain the proper level of ventilation whilst also maintaining the thermal efficiency required to meet the net-zero target by 2050. Trickle vents are excellent because they allow for ventilation without heat loss, so they should help keep your home safe from misty windows if left open during the night.

Isolating high humidity rooms and high humidity activities

High humidity rooms such as bathrooms are bad for causing misty windows across the home. The steam released when we shower can cause a lot of issues if not paired with an extraction fan or an open window. If not maintained properly, you could find that your home has an excess of humid areas and water vapour in the air.

If you close the door to your bathroom and leave the extraction fan on or the window open, the steam will have nowhere to go apart from outside, keeping it out of the home.

You can also do the same for drying your clothes or cooking; drying clothes releases a lot of water vapour in the air. The water from your clothes evaporates into your home’s air, if you do need to try your clothes inside, and will make your indoors humid and can cause steamy windows to build up and excessive condensation to follow. While cooking, cracking a window will also allow excessive steam to leave home, keeping your home dehumidified.

Using a dehumidifier

Dehumidifiers are purchasable machines that reduce the water content in your home’s air. Dehumidifiers work as a sort of reverse fan. They suck air in instead of blowing it out. As the air passes through the machine, they run over a cooling coil that condenses the water and collects it in a bucket built into the gadget.

Dehumidifiers cost anywhere from £100 to £150, so it can be quite a significant investment. However, if you are suffering from excessive condensation and steamy windows, it might be the product you’re looking for! We would recommend shopping around for a good deal as buying a cheap product might not affect what you’re hoping for.

Summary

So, suppose you are finding that you have a lot of condensation and misty windows. In that case, it is best to focus on ventilation first, as this is the easiest and cheapest way to remove excessive humidity within the home. If this doesn’t work, try isolating humid rooms and humid activities to spaces where you can ventilate easily. Finally, if none of this works, consider investing in a dehumidifier. It can be a substantial investment, but it should solve your issues if nothing else works.
