If you’ve ever wondered why your double glazed windows mist up, then read on.
Normally, the air inside the window is trapped to keep heat in, but when the seals on the panes are broken, either from age or from being poorly manufactured, condensation appears and this results in a misted window. However, there are many myths as to why this happens, so here are a few below alongside the real reasons double glazed windows mist up.
When Mist Occurs on the Outside of the Window
Contrary to popular belief, mist rising on the outer parts of a window is a natural occurrence and not caused by damage to a pane or window. It’s created when the temperature of the glass drops below a low level during the night in combination with the moisture of the morning dew, which condenses on the cold area of the glass in spring and autumn. The best way to rectify this is to install thermally efficient windows.
Effects It Can Have on Your Energy Bill
When your Dublin windows and doors mist up, it can cause higher heating bills because you’re losing insulation from the window as more heat escapes. However, by fitting a B-Rated window, which is based upon the type of glass rather than the frame, you could be saving yourself over £150 a year on your energy bills. Investing in energy-efficient glazing can not only help to reduce your bills but also your carbon footprint.
Should You Change the Window Frame?
Another common fallacy people tend to believe is that they should change the frame of a misted window, but provided the frame in intact, it’s not necessary to this. What’s more important is to replace the unit of glass. If you want to, you could even upgrade it to A-Rated by using reputable companies such as www.keanewindows.ie/ in order to keep your bills down and increase insulation.
One of the most important things to consider is not to fall into the trap of ‘quick fixes’. When your window is experiencing condensation and misting in between two panes, then the glass should really be replaced to keep your home more energy-efficient. Additionally, always use a regulated window fitter (FENSA) to help get the best deal for your replacement and even improve your energy-efficiency to A-Rated glass.
