Sometimes, the seals between the two glass panes can become damaged or worn out, causing condensation and misting on the windows. These problems are typically caused by moisture trapped between the glass panes or seeps into the wall through the window frame. Whatever the cause, moisture is bad news for double-glazed windows because it can lead to mold and water damage and can be expensive to deal with.

2. Seals

The window seal is a crucial element of double glazing and plays a crucial part in keeping your home energy efficient as well as draught-free and safe. The seal is located on the inner part of the uPVC frame and provides an air-tight seal over the gas-filled space between the two panes of glass that make up the window. This is a key part of the insulative effect the double glazing provides, and problems or frank failure to the seals will substantially diminish this benefit.
