However, condensation inside the glass panes is a different matter. Double glazing that is misty is more than a nuisance; it can be an indication that the seals on your insulated window unit have worn out or become damaged. Seals It is normal for condensation to form on the outside of double-glazed windows. This is a sign that your windows function properly. This is due to the air outside reaching its dewpoint quicker than your glass. If your windows are leaking on the inside this is a major concern and you should take action. This is because misting in the interior of your windows is usually an indication that there is an issue with the seal and that water is leaking into the gap between two panes. The seals on windows deteriorate over time because of ageing and wear and tear. They also degrade when exposed to harsh cleaning chemicals, which can damage the material. Poor window installation can also cause misting as the installer may not have utilized the proper fixing methods or set up the frame and insulated panels correctly. The gap between the two panes of glass in a double-glazed unit is filled with a spacer bar, which creates a thermal barrier as well as insulation. The spacer bar has a desiccant layer that absorbs moisture, keeping the gap dry. The condensation appears when the spacer bar gets damaged or worn out and the water that is trapped in the gap is able to pass through the seals. Poorly fitting and badly maintained double-glazing isn't only a source of condensation and damp, it can also impact the efficiency of your home. Faulty windows allow cold air to enter and warm air to escape and you'll be spending more money heating your home. If your windows are showing signs of misting, seek out a profession
