Misted Double Glazing

Double glazing that is misted is a sign of weakened seals that allow moisture enter the gap between the panes. This can affect the insulation properties of your windows and lead to various issues.

Condensation happens when warm air is in contact with cold surfaces and cools to its dewpoint. If this process isn't managed, your windows can become blurred.

Reduce Indoor Humidity

If your double glazed windows are misting, it's because there is an excess of humidity or water in the air. This water will condense if it touches a cold surface, such as the glass in your window.

If you wish to avoid misting, ensure that the area is well ventilated. Make use of extractor fans to reduce humidity in rooms that are hot. This will help prevent condensation on your windows, by keeping the humidity low in these areas.

A wide gap between double-glazed windows can aid in keeping them free of mist. If the gaps between the panes of windows are not enough, moisture can get in, and the seal may fail, leading to misting windows.

Another important aspect of the window's ability to withstand condensation is its insulation properties. Double-glazed windows are constructed of two separate glass panes, which are sealed together and have an opening bar between them. The spacer bar contains dessicant, which is designed to absorb and hold water vapour in the air. When the window cools, the silica will release the water vapour, preventing it from reaching its dew point, causing misting.

Over  misty double glazing repair , the seals could break down because of a variety of factors, including age, the method in which windows were constructed and cleaning chemicals.
