Double glazing that is hazy or cloudy and cannot be cleaned has likely been "blown". This happens when the gap between the window panes opens up due to deterioration of the window seals.
Replacing the gasket seals on your windows can fix this and it is far cheaper than replacing the entire double glazed unit.
Seals
The window seal, often referred to as the window gasket is responsible for sealing air between the two panes of glass in your double glazing. This will stop cold drafts from entering your home as well as keeping condensation and moisture from building up in the gap between the panes of glass.
As time passes, this seal will degrade due to rapid temperature changes throughout the year, which causes it to shrink and potentially break away from the frame. Replacing the window seals is a cheap and efficient method to repair your double glazing units.
A common sign that your window seals have broken down is condensation that forms between the two glass panes in a double-glazed window. This is caused by the accumulation of humidity inside the home - this excess moisture is unable to escape through the glass as it cools and condense on the surface of the window pane. This can cause windows to become misty and obstruct your view.
Additionally, if a window is misting, the condensation can also accumulate on the outside of the window frames. This can damage the timber frames as it can rot and cause a damp house.
