The condensation inside the glass panes, however, is a different story. Smudged double glazing could be more than an eye sore. It could also mean that the seals of your window units with insulation have deteriorated or are broken. Seals If condensation forms on the outside of your double glazing This is normal and a indication that your windows are working well. This is due to the air outside reaching its dewpoint faster than your glass. If your windows start to mist on the inside this is a major problem and you must investigate it. This is because misting that occurs on the inside of your windows is typically a sign that there is a leak in the seal and water is leaking into the space between two panes. Window seals degrade as time passes due to ageing and general wear and tear. They also degrade if they are exposed to harsh cleaning chemicals, which can damage the material. A poor window installation can cause misting if the installer didn't use the correct techniques for fixing or fit the frame or insulated panels correctly. A spacer bar is used to fill in the gap between two panes of windows that are double-glazed. This creates a thermal barrier and also acts as an insulation. The spacer bar is sprayed with a special desiccant, which absorbs moisture and keeps the gap dry. The condensation occurs when the spacer bar gets damaged or worn-out, and the water that is trapped in the gap moves through the seals. Poorly fitting and badly maintained double-glazing isn't only a source of condensation and damp - it can also damage the efficiency of your home. Faulty windows let cold air in and warm air to escape which means you'll be spending more money heating your home. If your windows are showing signs of misting, consult
