However, as time passes, they can start to fail. It is essential to identify the reason for this and how to repair it. As time passes the inert gases which fill the space between glass panes can escape from the unit via cracks or breakage. This is known as a blown double-glazed unit and in this case replacing it is the best option to bring back thermal performance and to create an air tight seal that stops cold air from entering the house. During the replacement process it is essential to examine the condition of the frame and ensure that it is in good condition. If there are indications of damage it should be repaired immediately to avoid any further deterioration or leaks.
