How to tell if your Double Glazing has failed? As a double-glazing repairs expert, we are often asked question in regards to failed double glazing. To help you understand whether or not it has failed, it is very important for you to understand what double glazing actually is. Double glazing comprises of two panes of glass put together with a thermally efficient spacer bar between them. The thickness of modern double-glazed unit is around 28mm thickness. This unit is sealed together by using a hot liquify adhesive. This double glazing unit is now sealed which means that all of the air is now trapped between the two panes of glass. If the double glazing is A-rated, then gas is applied and trapped between the two panes of glass instead. Now that the gas or air is trapped within the glazing unit, this acts as an insulated barrier. Therefore, preventing heat from escaping via the window whilst preventing cold air entering a home via the window. When gas is installed to glazing, this is much more energy efficient which allows the glazing to become A-rated. Why is my double glazing misting up? If the seal which surrounds the double glazing glass breaks down, or is damaged in some way, then condensation will build up. As this unit is no longer sealed, air and moisture can move freely inside of this glazing unit. Therefore, this is no longer a sealed unit and will no longer act as a barrier keeping the warm air in whilst cold elements out.
