A clean, clear pane of double glazing optimises the natural light that enters the room, as well as providing us with the best possible view out. If condensation covers your windows, the view and light is impaired, but are there other causes for concern?
Condensation on the Outside of Double Glazed Windows
If you’ve recently invested in replacement double glazed windows, you might be surprised to see condensation on the outside pane. Whilst exterior condensation might temporarily impede your view, it is actually showcasing the energy efficiency of the double glazing. In short, the heat from within your home is being retained, so the exterior pane of glass is colder than the air temperature.
The good news is that condensation on the outside of double glazed windows is usually quick to clear as the exterior temperature rises. Despite causing this temporary issue, the double glazed windows are actively working to prevent heat loss. This means it will take less energy to heat your home and as a result, the cost of your energy bills, along with your environmental impact, is lowered.
Condensation on the Inside of Double Glazed Windows
Condensation on the inside of double glazed windows is a little more concerning, as it can cause damp. You’ll find that it is most common in bathrooms, kitchens and bedrooms. It indicates a build-up of moisture within the room, rather than a particular problem with the windows.
As we head into the colder months, the contrast between cold outdoor temperatures and heated rooms becomes greater. This variation in the temperature will make condensation more noticeable. The most effective ways to reduce the problem are to:
- Open windows (even on the coldest days) for at least half an hour. This will allow fresh air to circulate and provide much-needed room ventilation which helps to reduce condensation.
- Make use of extractor fans when you are cooking or in the shower. These are designed to remove excess moisture from the room and prevent associated problems.
- Avoid drying laundry around the house. If it is a bright and breezy day, hang washing on the line, alternatively, make use of driers at the launderette. If you do have washing drying, keep it to one room, close the door and leave the window open whilst you are home.
Replacement double glazed windows will reduce persistent and severe internal condensation. One reason is that a ventilation strip is now included as a standard feature. Having said this, new windows won’t eliminate the problem, so other measures are needed to minimise the moisture levels.
Condensation between the Double Glazed Windows
Condensation on the inside, or outside, of double glazed windows may not be a cause for concern, but it is a different matter when the problem occurs between the panes. This indicates that the seal between the glazing panels has broken.
Double Glazed windows are energy efficient because the two panes of glass are separated. The transfer of heat is further reduced by trapping gases in the space between the glazing. If the seal has been compromised, the gases will escape and the efficiency of the window is reduced.
Furthermore, it is more difficult for the moisture to escape, so the condensation may be slow to clear. On cooler days, it might not clear at all. One thing is for certain, you are no longer gaining the heat retaining properties of your double glazed window, so it is time for a replacement.
