Upgrade to energy-efficient windows that are high-performance to control humidity and decrease the chance that condensation will develop within the glass panes. Regular cleaning is crucial for maintaining your double glazing. Even with this preventative measure atmospheric changes and general wear will eventually cause the seals to break down. Replacement The misting of double glazing is a common problem which can occur in most modern windows and doors. This happens when the seals break down and moisture is able to enter the gaps between the glass panes.

In most cases the sealed unit will fail because air enters the gap between the glass panes. This will cause water to get into the gap and cause condensation. When a sealed unit fails it will not be possible to clean the glass as this could damage the glass and cause further problems such as the possibility of the glass breaking and even longer-
