A damaged seal lets water vapour to get in, which reduces the window's insulation capabilities and increasing energy bills. While replacing the sealant is an option, replacing the glass unit is generally preferred for a long-lasting resolution. This also gives homeowners the opportunity to replace their windows with A-rated energy efficiency glass. Damage to the seals Double glazing that is hazy could be more than just an unsightly problem. It could also indicate that your windows aren't properly insulated or sealed. This can cause drafts to build up around your windows and increase your energy costs because you'll need to heat the home more often to keep it warm. This is why it's crucial to act fast whenever you notice that your double-glazed windows are starting to fog up. The good news is that there are a variety of ways to fix the issue and many of them will not cost the earth. The cause of misty double glazing is due to water vapour that has condensed between the glass panes. This can occur when the air in the room is too humid, or if a cold surface (such as glass window) comes into direct contact with the warm surface. In both cases, the humidity is sufficient to saturate anti-moisture gel (similar to the silica gel in new shoe boxes) that is located within the bars that separate the spacers. This leaves the granules in no position to dry out the moisture between your two glass panes. Unfortunately, it's not as simple as just replacing these granules because they are embedded within the sealant that has been degraded due to wear and tear or by the damage caused by the installation process. Keep in mind that no sealant can be 100% effective, and it is inevitable that some water will leak in over time. This is the same for Argon
