How to Prevent Condensation Inside Double Glazed Windows
Condensation in double glazing units is a common problem that often occurs as windows near the end of their lifespan.
Double glazed windows are a lot more resistant to condensation and fogging than single glazed windows, but they are still prone to moisture getting trapped between the two single panes of glass that provide the double glazing. Tiny silica balls are included in the spacer bar that separates the two panes to absorb any moisture that gets in, but over time, the unit can start to leak and you might see fogging on the window.
A++ rated double glazed windows are extremely hardwearing, well-insulated and thermally efficient. If you select a high-quality installer using premium products, you should not experience any issues with condensation until your windows are at least twenty years old. However, there are some measures you can take to ensure the longevity of your double glazing and prevent condensation from obscuring or damaging the windows.
- Don’t dry your clothes on radiators near the windows too often — this can increase the amount of damp in the air and the risk of condensation occurring
- Open the windows and ventilate your rooms often, allowing air circulation to clear the moisture in the air
- If your home is particularly humid or damp, invest in a dehumidifier to clear the atmosphere
- Don’t let the temperature get too low; if you’re going away in the winter, keep the heating on low to ensure that your pipes and windows don’t freeze
- If you have a tumble dryer, the air vent should not be blowing against any windows
Sometimes, condensation builds up in the air gap between glazing panes due to a temporary fluctuation in temperature or humidity. Once the atmosphere clears, so does the window. Unfortunately, if the condensation in your double glazing air gap is consistently visible, it’s a sign that the window has “blown” and the seal that creates the sealed unit has failed, allowing moist air into the gap. Wise Property Care advises that you don’t allow condensation to sit unattended inside your window panes, as this can lead to larger issues over time, such as wet rot or dry rot.
