Water vapour can get through damaged seals, reducing window insulation and increasing the cost of energy. While replacing the glass unit could be a better option to ensure a long-lasting solution it is often preferred to renew the sealant. This gives homeowners the chance to upgrade their windows by making use of energy efficient glass with an A rating. Seals damaged Misty double glazing isn't just an unsightly issue. It can also indicate that your windows aren't properly sealed or well-insulated. This could lead to drafts around your windows and higher energy bills as you have to heat your home more often to keep it warm. It's essential to act fast when your double glazing begins to fog. There are a variety of options to solve this issue and they don't have to cost you a lot. The reason for misty double glazing is due to water vapour that has condensed between glass panes. This happens when the ambient air becomes too humid or when a cold surface (such as windows) is in contact with a warmer surface. In both cases, the humidity is sufficient to fill the anti-moisture granules (similar to the silica gel you find in new shoe boxes) within the spacer bars of the double-glazed unit, leaving it saturated and unable to dry out the water between the two glass panes. It's not easy to replace these granules because they are embedded in the sealant, which is weakened from wear and tear, or any damage that occurred during the installation. It is important to remember that no sealant is 100% effective so it's inevitable that a tiny amount of water will get in over time, much as Argon gas and air will escape. The best way to prevent misting is to ensure that the space between two glass panes is always completely free of any misting. This can
