Water vapour can get through damaged seals, which can result in lower window insulation and increasing energy costs. While renewing the sealant is an option replacing the glass unit is usually preferred for a lasting resolution. This gives homeowners the opportunity to upgrade their windows using A-rated energy efficient glass. Damaged seals Misty double glazing is more than an unsightly problem, it could also mean that your windows aren't sealed or insulated. This can cause draughts to build up around your windows and increase your energy costs as you'll have to heat the home more frequently to keep it warm. This is why it's crucial to act fast when you notice that your double-glazed windows are beginning to get cloudy. The good news is that there are plenty of solutions to the issue, and most of them will not cost the earth. The reason for misty double-glazing is water vapour that has condensed between the glass panes. This can occur when the air in a room becomes too humid or when the cold surface (such as windows) is in contact with a warmer one. In both cases, the humidity is high enough to soak the anti-moisture granules (similar to the silica gel you find in new shoe boxes) within the bars that separate 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 simple to replace these granules as they are encased in the sealant, which has been weakened by wear and tear, or damage that occurred during the installation. Remember that no sealant will be 100% effective, therefore it is inevitable that some water will leak in over time. The same is true for air or Argon gas. The best method to avoid misting is to ensure that the space between t
