Condensation in double glazing
I have been doing some research on the causes of condensation inside the sealed unit of double glazing and found some very questionable advice.
It was claimed that inside a double glazed sealed unit is some silica balls that absorb condensation and when these are all used up the condensation start to condense inside the sealed unit. there is some truth to this however this is not why your sealed unit has failed.
If you have condensation between the two panes of glass it means two things.
- Your sealed unit is no longer sealed.
- Your argon gas has escaped and you no longer have the thermal benefits of the argon gas slowing down heat transfer.
Basically your sealed unit either has to be replaced or better advice would be to replace your window.
Replacing the sealed unit will fix your condensation problem for the moment however it does not fix the real reason why it has occurred; therefore it will reoccur in your new sealed unit.
There is only one reason a sealed unit will fail in normal use and that is because the window does not have sufficient reinforcement in the frame and in the window.
When people make cheap windows they only add metal reinforcement to hold a screw, hinge or lock, however by doing so you are not protecting the sealed unit so the window starts to bow in the middle and through time this lack of support and the vibration from noise and opening and closing the window will eventually break the seal of the unit.
In short you get what you pay for; if you don’t compromise on design or quality your sealed unit will never cause you a problem again.
