Water vapour can enter through damaged seals, reducing window insulation and causing higher the cost of energy. While replacing the glass unit may be a better option for a long-lasting solution, it is generally recommended to renew the sealant. This allows homeowners to upgrade their windows by using A-rated energy efficient glass. Damaged seals Double glazing that's misty could be more than just an ugly issue. It could also mean that your windows aren't properly insulated or sealed. This can cause drafts to form around your windows and increase your energy bills because you'll have to heat your home more frequently to keep it warm. It is crucial to act quickly when your double glazing begins to fog. There are a variety of ways to fix this problem and they don't have to cost a lot. The cause of misty double glazing is water vapour that has condensed between glass panes. This happens when the ambient air becomes too humid or when the cold surface (such as a window) comes into contact with a warmer surface. In both instances, the humidity is enough to saturate the anti-moisture granules (similar to the silica gel that is found in new shoe boxes) within the spacer bars of the double-glazed unit, which makes it ineffective and in a position to dry out the moisture between the two glass panes. It's not easy to replace these granules since they are encased in the sealant that is weakened by wear and tear or any damage that occurred during the installation. It's important to note that no sealant can be 100% effective so it's inevitable that a tiny amount of water will seep into the seal over time, just as air and Argon gas will leak out. The best method to avoid misting is to make sure that the space betwee
