Damaged seals allow water vapour in, reducing the window's insulation properties and increasing energy bills. While replacing the glass may be the best option to ensure a long-lasting solution it is usually preferential to renew the sealant. This also gives homeowners the chance to replace their windows with A-rated energy efficient glass. Damage to seals Double glazing that is misty isn't just an unsightly problem, it can also indicate that your windows aren't sealed or aren't properly insulated or sealed. This can cause drafts to form around your windows and increase your energy costs because you'll have to heat the home more often to keep it warm. This is why it's crucial to act fast if you notice that your double glazing is beginning to get cloudy. The good news is that there are plenty of solutions to the issue, and most of them won't cost the price of a house. The condensation of water vapour between the glass panes causes misty double glazing. This may occur when the air in the room is too humid, or when a cold (such as windows made of glass) comes into direct contact with the warm surface. In both cases, the humidity is sufficient to fill the anti-moisture granules (similar to silica gel found in the new shoe boxes) within the bars that make up the spacers of your double glazed unit, making it saturated and unable to dry out the moisture between the two glass panes. It's not simple to replace these granules as they are embedded in the sealant, which is weakened by wear and tear, or any damage that occurred during the installation. It's worth remembering that no sealant is 100% effective so it's inevitable that a small amount water will seep in over time, just as air and Argon gas will escape. The best
