It is an indication of the need to replace the window. The good news is that it is usually fixable. Double glazing is comprised of two glass panes sealed by an air gap (sometimes Argon gas is used) to form an insulating layer and prevent heat from escaping. If this seal is not maintained, it can cause the tell-tale condensation build-up. Glass unit repair or replacement If you notice a haze of mist on the outside of your double glazing, this is normal and occurs when the air warms up faster than your glass, such as early in the morning. This will cause the air to reach its dew point and begin to condense. However, if this happens on the inside of your window it generally means that the sealed unit has failed. This is a major issue that can be a challenge to fix and could need replacement of the entire window or at least the glass panes. A professional window installer will visit your home and advise you on what the best solution is. There are many methods to fix a blown window, but the most effective is to replace the glass panes. It is typically less expensive than replacing the entire window, and could even permit you to upgrade to a higher-quality glass to improve your home's energy efficient. A good firm will provide a complete warranty with the replacement and ought to provide a no-cost estimate without obligation. De-misting agents are a cheaper alternative. They work by drilling a tiny hole in the glass unit. This pump then injects a dry ingredient into the gap between glass to help absorb moisture. This is only a temporary fix, and will make the windows vulnerable to condensation in the future, as the granules of the spacer bar are saturated with moisture. Another option is to heat the frame and glass to get rid of any moisture however this method only works for a brief period
